Session Title: From monsoons to mixing: coupled ocean-atmosphere processes in the Northern Indian Ocean
Session Description: The Northern Indian Ocean is a unique semi-enclosed tropical ocean basin whose dynamics are
forced by and coupled to the summer and winter South Asian Monsoons. The feedback between the ocean and
atmosphere influences regional to global weather patterns, often with major societal impact. This session aims to
synthesize our understanding of the role of the oceans on the South Asian Monsoons through observations, modeling,
and theory. Topics of interest include upper ocean processes, air-sea interaction, boundary currents, freshwater
dispersal, and mixing in the Bay of Bengal and Arabian Sea. We encourage presentations that characterize the upper
ocean structure and identify key processes that set the lateral and vertical temperature-salinity distribution over a range
of length and time scales. Processes that influence bio-optical and biogeochemical property distributions are also of
interest. We welcome studies that focus on the factors controlling sea surface temperature, surface fluxes, and air-sea
coupling on diurnal to intraseasonal scales, including those associated with the Madden-Julian Oscillation and other
tropical instabilities.

Session Title: Tropical Cyclone-Ocean Interactions: from Weather to Climate
Session Description: Tropical Cyclone (TC) ??Ocean interactions are critical processes for TC intensity change because
the ocean is the energy source for TCs. The air-sea interaction processes involve energy and momentum exchange
between TC and the ocean and are important in both TC (i.e., short-term) and climate (i.e., long-term) timescales. In the
TC timescale, TC-ocean interactions are critical to intensity forecasting. The intense TC wind also made significant impact
to the ocean through entrainment mixing and upwelling. In climate timescale, how the future ocean will evolve has
strong implications for future TC activity projection and consequential societal impact. Meanwhile, natural inter-annual
(e.g., ENSO) and inter-decadal (e.g., the Pacific Decadal Oscillation and Atlantic Multidecadal Oscillation) and global
warming also affect the ocean, TC, and their interactions. This session welcomes submissions under the broad discipline
of TC-ocean physical and biogeochemical interactions from
weather to climate timescales. It intends to provide a friendly platform for interactions among oceanographers,
atmospheric scientists, and climatologists in this multi-disciplinary field.

Session Title: James J. O'Brien Symposium: Advances in Air-Sea Interaction over the past 45 years and emerging
priorities
3|Page
Session Description: Air-Sea Interaction focuses on the transfer of energy and momentum between the atmosphere and
ocean. The field of air-sea interaction spans theoretical modeling and coupled prediction, process-studies based on situ
observations, satellite-based observations, flux coupling for ocean and atmospheric models, and the analysis of
spatial/temporal variability in surface turbulent fluxes. Over the past 45 years at Florida State University, James J.
O’Brien has been a leader of interdisciplinary research in air-sea interaction, the coupled ocean-atmosphere-land-ice
earth system, and climate prediction on scales of weeks to decades in order to increase understanding of the physical,
social, and economical consequences of coupled ocean-atmospheric variations. This symposium will include contributed
presentations on all aspects of air-sea interaction across a wide spectrum of temporal and spatial scales with an
emphasis on emerging and future priorities in the fore-mentioned areas.

Session Title: Upper-ocean Salinity Variability and its Impact on Climate
Session Description: Salinity variability and its vertical structure in the upper ocean affect the properties of the surface
mixed layer, oceanic circulation, and vertical mixing, thus altering the exchange of mass, momentum and heat at the airsea interface. Through its influence on ocean heat transport and sea surface temperature, upper-ocean salinity plays an
important role in weather and climate. With a growing database of satellite and in situ observations, progress has been
made toward characterizing spatial variations and intraseasonal to interannual changes in salinity. However, challenges
remain, particularly for quantifying long-term fluctuations and their climate impacts. This session seeks to bring together
recent efforts aimed at better understanding salinity variability and its influence on climate. Contributions are invited on
all aspects of upper-ocean salinity variations from the perspectives of observations and numerical models, including
phenomena such as the Madden–Julian oscillation (MJO), El Niño Southern Oscillation (ENSO), monsoons, and the
Meridional Overturning Circulation (MOC).

Session Title: Impact of the Ocean on Forecasting the Earth System from Weather to Climate Scales
Session Description: Earth System Models coupling ocean-atmosphere-ice models have been run at coarse resolution
for climate studies for than a decade. New efforts are underway to extend coupled weather models at high resolution
to longer time scales and increase the resolution of existing coupled climate models. Eddy heat flux and frontal air-sea
interaction are different between the coarse and high resolution coupled models. These differences potentially may
impact the results from climate change simulations. We seek talks describing the differences in the coupled systems at
different resolution and the impact of the ocean and its parameterization on air-sea interaction in coupled earth system
models.

Session Title: Atmospheric deposition and ocean biogeochemistry.
Session Description: Atmospheric deposition of marine, lithogenic and anthropogenic aerosols is an important transport
pathway for nutrients and contaminants to the surface ocean. Constraining local, regional and global atmospheric
deposition flux estimates and the bioavailability of aerosol-derived elements and compounds is essential for furthering
understanding of ocean biogeochemistry. This transport pathway acts as an important chemical bridge between the
lithosphere and hydrosphere linking major biogeochemical cycles. Aerosol emission, transport and deposition processes
are, in part, a function of global change related to changes in land coverage, anthropogenic emissions and climate.
Hence the study of ocean responses will improve our ability to predict future impacts. The GEOTRACES international
program includes objectives related to the atmospheric input of trace elements and isotopes to accomplish its goal.
5|Page
Other programs, such as SOLAS and CLIVAR, continue to make significant contributions as well. This session invites
contributions from studies of atmospheric deposition in the marine environment, including observations of atmospheric
deposition fluxes, aerosol composition, aerosol fractional solubility, the fate of aerosol-derived compounds and the
biological and chemical response to deposition within the surface ocean. Contributions from global and regional scale
field observations, laboratory studies and modeling efforts are welcomed.

Session Title: Interactions between the Kuroshio and Asian marginal seas
Session Description: The Kuroshio is a major western boundary current in the North Pacific, carrying tremendous
amount of water mass, heat, and salt from low to mid latitudes and thus affecting physical and biogeochemical
properties along its route. Asian marginal seas, such as the South China Sea, the East China Sea, and the Japan-East Sea
along the northwest rim of the Kuroshio, have shown distinct dynamic connections to the variability of the Kuroshio. The
exchanges between the Kuroshio and marginal seas can affect both the dynamical structures in the marginal seas and
the behavior of the Kuroshio, which could also be coupled with mesoscale eddies, local forcing, shelf processes, etc.
With increased efforts in development of in-situ monitoring, remote sensing and high-resolution numerical models, our
understanding of the impact of Kuroshio has significantly advanced in recent years. This session calls for presentations
featuring new results on the interactions between the Kuroshio and Asian marginal seas. Presentations that address
interactions between other boundary currents (e.g., the Mindanao and Oyashio currents) and Asian marginal seas, the
open Pacific Ocean, and the atmosphere, are also invited.

Session Title: Linking the Ocean with the Atmosphere - Exploring the Importance of the Ocean-Atmosphere Interface
and Near Surface Waters in Global Scale Processes.
Session Description: The sea surface microlayer (SML) is the interface layer between the ocean and the atmosphere,
controlling a variety of physical, chemical and biological properties and processes, including gas- and heat-exchange,
microbial diversity, biogeochemical cycling and the emission of aerosols. Recent technical developments such as the
application of high-throughput sequencing to assess microbial diversity within the SML and autonomous techniques to
quantify the physiochemical properties of the interface are significantly advancing our understanding of the interactions
between near surface waters and the lower atmosphere. Experimental studies applying controlled wind fields, or
simulating sea spray formation, furthermore advance our understanding of the SML and its diverse components.
However, to achieve a comprehensive understanding of the processes that occur at the interface layer requires the
development and application of interdisciplinary scientific approaches.
For this multidisciplinary session we invite participants from all research disciplines that are interested in the sea surface
microlayer and near surface waters. We will explore the interactions between physical, chemical and biological
processes at the ocean-atmosphere interface so that we can develop a holistic perspective and promote the
development of new collaborations between research fields.

Session Title: Physical processes driving the Ocean Surface Boundary Layer
Session Description: The ocean surface boundary layer (OSBL) lies at the interface between the atmosphere and the
ocean, and steers the pathway for heat and mass exchange between the atmosphere and the deep ocean. The OSBL is
7|Page
forced on diurnal timescales, and its variation has impacts on atmosphere-ocean coupling on weather and climate
timescales. The OSBL has been the subject of intense theoretical study recently, with the discovery that for example
surface wave processes and submesoscale processes play key roles in deepening and shoaling the OSBL. These
theoretical developments have motivated new observational programmes, which are just beginning to report results.
The combination of this new theory and observations will drive a new generation of parameterisations of the OSBL for
global weather and climate models. Papers are invited that report theory, modelling, observations or parameterisation
development of the OSBL. Studies of the OSBL from diurnal and longer timescales through to impacts on weather and
climate are within scope.

Session Title: Oceanic Whitecaps, their Significance to Air-Sea Exchange
Session Description: Whitecaps, the sea-surface foam signatures of the sub-surface bubble plumes generated by airentraining breaking waves, are distinguishable patches on the ocean surface associated with markedly enhanced air-sea
exchange processes. These features and the turbulence associated with them enhance the ocean-atmosphere exchange
of gases, especially those of relatively low solubility. The bursting bubbles within whitecaps are also a major source of
the sea spray droplets that transfer moisture, heat, salt, and marine organic matter to the atmosphere. Whitecap
coverage, which can be used to estimate the gas transfer coefficient and the sea surface spray production flux, can be
estimated from meteorological variables, but can also be retrieved from passive microwave satellite data. Current
modeling efforts and observational programs are aimed at improving the community’s abilities to parameterize
whitecap coverage and the related air-sea interaction processes. Submissions are welcome on the broad range of field,
laboratory, and modeling studies aimed at improving our knowledge of the factors influencing oceanic whitecap
coverage, and on the resulting improved parameterization of gas transfer, sea surface aerosol production, and other
whitecap-related air-sea exchange processes.

Session Title: Coastal submesoscale processes: Physics, biogeochemistry, and their interactions
Session Description: Sub-mesoscale features in the ocean, frequently manifested as filaments, fronts, and eddies, are
characterized by both O(1) Rossby number and a horizontal scale smaller than the internal Rossby radius of
deformation. Sub-mesoscale processes are important as they contribute to the vertical transport of oceanic tracers,
mass, and buoyancy and rectify the mixed layer structure and upper-ocean stratification. The coastal ocean, where most
anthropogenic activities take place, is especially sensitive to these processes. This session invites observational,
theoretical, and numerical modeling efforts associated with submesoscale processes in coastal environments and shelf
seas within the scope of the ocean physics, biogeochemistry, and their interactions.

Session Title: New Oceanographic and Atmospheric Knowledge through High-Performance Computing (HPC)
Session Description: Oceanographic and Atmospheric processes are highly complex and often couple with each other
and with land. New advances in HPC enabled models or efficiencies in algorithmic designs enable study or simulation of
these processes at higher resolutions and/or with more complex physics. Such advances can yield new scientific insights
into oceangraphic/atmospheric dynamics, coupling, or effects these processes have over the Earth. This session invites
presentations from oceanographic and atmospheric research using HPC that enhances knowledge of these processes
through discovery of previously unseen effects, enablement of new capabilities for coupling of complex and
heterogeneous processes, or estimation of uncertainty that is lowered or previously unknown. We seek contributions
9|Page
that attain these results through – but not limited to – HPC enabled study, HPC simulation results, or innovation in HPC
algorithm design.

Session Title: Observations and modeling of physical processes at the air-sea interface
Session Description: The exchange of momentum, energy, and mass across the air-sea interface is of significance for a
number of atmospheric and oceanic processes, such as wind wave growth, vertical heat flux, and mixing. These complex
dynamics exist over a wide range of spatial and temporal scales, with implications for local, regional, and climatic
variability. Challenges remain in understanding the nature of the air-sea interface in extreme conditions and along
coastal margins. This session will provide a forum for studies focused on furthering the general understanding of air-sea
coupling in a variety of physical regimes. Laboratory, field, and modeling investigations into the role surface processes,
such as waves, spray, bubbles, and turbulence, have on the fluxes across the interface are encouraged. Presentations of
novel techniques or venues for air-sea interaction study are of particular interest. Results from remote sensing of these
surface processes are also welcome.

Session Title: Mid-latitude Climate Dynamics and the Role of the Ocean
Session Description: Climate dynamics is fundamental to understand and predict regional to global climate variability
and change. More information on this topic is rapidly becoming available due to increasing amount of data from both
models and observations, particularly at high resolution. International climate research programmes such as CLIVAR
recognize the importance of climate dynamics. This session explores climate dynamics in mid-latitudes and the role
played by the ocean. Four major topics of this session are: 1) storm tracks, jet streams and weather systems, 2) air-sea
interactions, in particular ocean-to-atmosphere influences, including those over oceanic currents and fronts, 3) climate
phenomena such as the North Atlantic Oscillation, Pacific Decadal Variability, teleconnections and their relevance for
regional climate variability and change and 4) processes, variability and change in the ocean and coupling with other
components of the climate system, such as the cryosphere and stratosphere. Theoretical, numerical and observational
studies are welcomed.

Session Title: Ocean Circulation and Biogeochemistry in a Water Mass Framework
Session Description: Water masses are the phenomenological expression of large-scale dynamical processes in the
ocean, and for this reason have long been the foundation of our characterization and understanding of large-scale ocean
circulation. Recent and ongoing advances have focused on dynamically-active tracers (e.g. density, temperature, salinity
and potential vorticity), as these lend themselves most directly to characterizing the budgets of heat and freshwater and
more generally the overturning circulation. In addition a water mass framework is general, and can provide insight into
the dynamical and thermohaline controls on ocean biogeochemistry and the ocean carbon cycle.
Recently significant attention has been devoted to water mass modification processes (formation, erosion) occurring
within the ocean interior, and connecting this to surface transformations and the large-scale overturning circulation.
Additional efforts have begun to consider this for the case of ocean biogeochemistry as the concepts of interior
ventilation and dynamical controls on preformed nutrients and carbon are intrinsically linked to water mass formation
processes in the ocean’s surface boundary layer.
11 | P a g e
This session welcomes studies that exploit in-situ and integrated observations, theory, and numerical modeling-based
analysis (both Eulerian and Lagrangian). Abstracts are welcomed that focus on physical processes, biogeochemical
processes and/or the interplay between the two.

Session Title: High Latitude Air-Sea-Ice Interactions in a Changing Climate
Session Description: Exchanges of heat, mass and momentum across the air-sea interface impact the ocean and
atmosphere and their interactions within the coupled climate system. These exchanges, significantly enhanced in polar
regions by large air-sea temperature differences and high wind speeds, contribute to water mass modification and
ventilation that in turn impacts biochemical and physical conditions throughout the world oceans. Sea ice modulates
these processes and results in complexity that, combined with a sparsity of data in polar regions, contributes to
uncertainty regarding their spatial and temporal variability and large scale impacts. This session provides a venue for
the exchange of new information on all aspects of high latitude air-sea-ice interaction, including processes at the
interface and investigations of their impacts on local ocean, atmosphere, and sea ice processes as well as the larger
coupled climate system.

Session Title: Surface Water Mass Formation based on Satellite Observations
Session Description: The interior ocean circulation is governed by surface water mass properties (salinity, temperature,
density) in the convection and subduction source regions. These surface water properties are governed by heat and
moisture fluxes at the air-sea interface. The recent advent of satellite salinity measurements now makes it more
feasible to study these processes from space. Surface density and spice are being added to the next Aquarius satellite
data version (May 2015). However, cold water temperatures, sea ice and high winds compromise the high latitude
satellite salinity measurement accuracy and thus present a unique challenge. This session is intended to attract reports
on early analysis results of satellite remote sensing data to investigate surface water mass formation and variability in
mid to high latitude oceans. Satellite data sources may include sea surface salinity (SSS), temperature (SST), vector
winds, surface topography, gravity, air-sea fluxes, and ocean color, as well as in situ observations and numerical
modeling.

Session Title: The Dynamics of the Air-Sea Interface: Application to Oceanic Mixing and Transports
Session Description: The dynamical properties of the air-sea interface directly influence air-sea exchange of mass,
momentum and energy. The presence of whitecaps, sea ice, oil spills, or surfactants will have a significant impact on the
upper ocean dynamics, often in a complex interplay between the surface material, the mean flows in the air and water,
and the surface waves. As far as ocean circulation models are concerned, such processes must be parameterized by
changing the surface boundary conditions and/or modifying the internal model dynamics. One such example is the
inclusion of sea state dependent momentum and energy fluxes, which is highly relevant for modeling the transport of
dispersed oil or pelagic plankton.
13 | P a g e
In this session we welcome theoretical, numerical, and experimental studies of the properties of the air-sea interface.
This includes how various surface covers impact on surface waves and also how the upper ocean currents and mixing
depend on the waves and the properties of the air-sea interface itself.

Session Title: Understanding Air-Sea Coupling in Tropical Cyclones for Improving Model Intensity Forecasts
Session Description: Improvements in tropical cyclone intensity forecasts produced by coupled prediction models have
lagged behind improvements in track forecasts. Accurate intensity prediction requires that coupled models correctly
simulate the evolution of air-sea heat and momentum fluxes directly beneath storms. Limited evaluation performed to
date demonstrates that existing coupled prediction models contain significant errors and biases in simulated air-sea
fluxes, and in the responses of the upper-ocean and the atmospheric planetary boundary layer to these fluxes, that can
degrade the quality of intensity forecasts. Papers are solicited that describe the supporting science and methods
required to evaluate and improve the quality of coupled TC intensity forecasts, particularly with regards to improving
the representation of key ocean-wave-atmosphere physical processes within the models. Particular emphasis is placed
on physical processes acting within the under-sampled inner-core region of storms. Scientific topics of interest include
air-sea interface dynamics, upper-ocean dynamics, atmospheric planetary boundary layer dynamics, air-sea flux
parameterization improvements, and methods to improve model initialization. Papers describing the observational
requirements to achieve these goals, with respect to both the optimal use of existing observations and the design of
future observing programs, are particularly encouraged.

Session Title: Air-Sea Exchange Processes in Western Boundary Current Systems and Marginal Seas: Their Local and
Remote Climatic Implications
Session Description: This session focuses on intense surface fluxes of heat, moisture and momentum within western
boundary current systems and adjacent marginal seas, known as climatic “hot spots”. Particular emphasis is placed on
oceanic and atmospheric processes over a wide range of spatial and temporal scales that contribute to huge amounts of
heat and moisture supplied from the ocean to the atmosphere and wind forcing onto the ocean as well. Contributions
for oral and poster presentations based on diagnostic, modeling (either realistic or idealized) and theoretical studies are
invited on a range of topics including, but not limited to, the processes affecting spatial and temporal variations in
surface fluxes around the oceanic fronts/jets and meso-scale eddies, their local and large-scale influence on air
temperature and wind distributions, organization of cloud and precipitation systems, cyclone development, the
formation of storm tracks and jet streams, and their feedbacks/influences on ocean currents/jets and mode water
formation, and their interactions with marine ecosystems. Observational (both in situ and remote sensing) analyses to
characterize these processes and to evaluate their representations in atmosphere/ocean models and reanalyses are
encouraged. Contributions are also invited on surface chemical fluxes and related processes.

Session Description: Air-sea exchange processes occur across the sea-surface microlayer and are influenced by the
microlayer properties. The presence of bubbles, microbes, and surfactants all affect the microlayer properties, and in
turn influence the aerosol and gas flux across the interface. This session aims to bring together ideas and results from
15 | P a g e
field observations, laboratory experiments, and physical models. We welcome talks related to bubbles, microbes, and
surfactants, including those focusing on scavenging, enrichment of bioparticulates in aerosols, and gas exchange in low

Session Title: Interactions between ocean waves and environment – in observational numerical and theoretical studies
Session Description: Ocean waves propagate at a wide range of temporal and spatial scales. Their development and
evolution depend strongly on the surrounding environment, for example oceanic currents, turbulence, topography and
sea ice. In particular, in the latter two cases, wave processes related to bottom friction, shallow water coastal wave
breaking and sea ice in the marginal ice zone, are largely dissipative. Moreover, in terms of anthropogenic factors,
offshore wind farms and tidal/wave energy converters modify the natural environment and thus interact with waves. To
improve marine weather forecasting and climate studies, recent efforts have attempted to use numerical and
experimental approaches to elucidate the coupling dynamics that combine ocean, waves, atmospheric and ice models.
Although significant process has occurred, challenges remain. For example, the interactions between waves and oceanic
turbulence and its intermittent behavior are not yet solved. In this session, contributions are invited relating to
experimental, numerical and theoretical studies of the interactions of ocean waves and the environment, including
ocean currents, sea ice, coastal structures, the seabed and related processes at all spatial and temporal scales.

Session Title: Ocean Surface Wind: Advances in Observations, Processes, and Impacts
Session Description: Ocean surface winds are important to the exchanges of momentum, heat, freshwater, and carbon
across the air-sea interface. They regulate ocean-atmosphere coupling and influence the ocean and atmosphere
circulations and the associated property transports. Advances in remote sensing have allowed better examination of
these wind-related processes as well as the related impacts. Specifically, finer resolution, intercalibration, and sampling
across the diurnal cycle are improving our ability to characterize and understand the wind-related processes. More
detailed examples of the processes include the diurnal variability of wind forcing of the ocean, wind coupling with
precipitation, wind forcing coupled with currents and the related impacts on transport. The smaller scale processes
contribute to larger scale phenomena and thus impact the cycles of energy, water and carbon. This session focuses on
processes associated with ocean surface wind, the interactions between small- and large-scale processes, and the
impacts on the important cycles mentioned above. Both observational and modeling studies are encouraged.

Session Title: ESA’s SMOS Satellite Mission Salinity Datasets and Relevant Oceanographic Applications
Session Description: ESA’s SMOS mission is successfully operating and delivering, over ocean, global sea surface salinity
(SSS) data to the science community since 2009. This session will address major scientific achievements based on SMOS
datasets, with an emphasis on synergetic products and process studies, including applications with potential for
operational services, given the availability of multi-annual high quality data. The session will focus on the following
themes: • Major oceanographic achievements based on SMOS sea surface salinity (L2-L3) data;
• Salinity variability at different spatial and temporal scales;
• Synergistic use of SMOS measurements with different remote sensing SSS products (Aquarius, SMAP) and additional
Earth Observation datasets;
• SSS relevance in thermohaline circulation and ocean dynamics;
• Salinity as a tracer for freshwater fluxes characterization;
• Salinity role within ocean-atmosphere interactions (e.g.; barrier layers, upwelling, tropical cyclones);
17 | P a g e
• Salinity and ocean biogeochemistry;
• Data fusion for the generation of long-term datasets and ECVs over ocean;
• Salinity distribution links with climatic variability (El-Niño, la Niña, IOD, MJO etc);
• Salinity Data Assimilation into ocean circulation models.

Session Title: Physical, biological and biogeochemical impacts of shelf-deep ocean exchanges in highly productive
continental shelves
Session Description: The exchange of mass, energy and constituents between the continental shelf and the deep ocean
has a profound impact on the physical, biological and biogeochemical properties of both marine systems, may play a key
role on export of biodiversity and trace elements, and in the long-term ocean sequestration of carbon dioxide from the
atmosphere. The on-shelf flux of nutrients from the deep-ocean, for example, promotes the growth of phytoplankton
while the export of organic material from the shelf to the deep-ocean can contribute to long-term carbon storage. The
synergistic interaction and exchange of properties between the shelf and the deep ocean leads to the development of
some of the most important marine ecosystems of the world ocean. In this session we welcome presentations focused
on the physics, biology and biogeochemistry of shelf-open ocean exchanges of highly productive shelf regions.

Session Title: The Ocean Surface Mixed-Layer: Critical Roles in Weather, Climate and Biogeochemistry
Session Description: The Ocean Surface Mixed-Layer (OSML) regulates sea surface temperature and salinity, air-sea
exchange, oceanic storage and transport of heat and gases (e.g., oxygen, carbon dioxide), solar penetration for
phytoplankton and biological productivity, ice-ocean interactions, and ocean circulation responses to atmospheric
forcing. Quantification of OSML processes and properties is thus crucial for accurate description and prediction of a
variety of climate, weather and biogeochemical phenomena. The subsurface observations needed to quantify upper
ocean properties, however, are sparse and numerical models are limited by computational restrictions, incomplete
representation of fine-scale processes, and boundary condition errors. Capturing OSML variability on a global scale is
therefore a critical challenge that requires the development of new approaches to observation and estimation. We
invite the submission of abstracts for observational, modeling, or theoretical studies that describe and evaluate new or
existing techniques to quantify and understand the variability of OSML properties (such as mixed-layer depth), or that
consider science impacts of the limitations and errors inherent in such techniques. Of particular interest are studies that
examine existing or proposed OSML data or model products, or that demonstrate a specific need for improved estimates
of OSML properties.

Session Title: How does the pump pump? Evaluating the processes behind the Ocean's Biological Carbon Pump
Session Description: A major term in the carbon cycle is the ocean’s biological carbon pump (BCP) which is mediated by
the export of organic particles and dissolved organic carbon (DOC) from the surface ocean to depth below the main
thermocline. Representing the export flux and remineralisation rates of particles in biogeochemical models is
challenging: firstly, it is not clear which are the processes to include and secondly, there is often insufficient data to
parameterise those processes anyway. Consequently, both export flux and remineralisation rates are often represented
using uniform empirical relationships that potentially overlook specific processes essential to a mechanistic
understanding of the BCP. However, recent developments in optical/geochemical sensors, particle collection devices and
radiochemistry, as well as global data compilations and time series, have the potential to enable novel understanding of
export and its mesopelagic attenuation. Nonetheless, the influence of ecosystem structure, microbial community,
temperature, oxygen, DOC production, sinking material quality, ballast content and aggregation/disaggregation on
mesopelagic remineralisation rates is poorly constrained both in open and boundary regions. To pursue this effort, this
session invites contributions on observational, experimental, empirical or model studies that address the processes
controlling the export of biogenic elements from the surface ocean and their mesopelagic remineralisation

Session Title: Effects of Ocean Acidification on Carbonate Dissolution Processes and Rates in Reef, Bank and Shelf
Sediments
Session Description: Fossil fuel and land-use emissions of CO2 to the atmosphere have created the "other CO2 problem"
- the absorption of ~25% of that CO2in surface seawater resulting in increased ocean acidity. Considerable experimental
and observational research exists with regard to the effect of an increase in seawater acidity on the calcification rates of
organisms and the production of CaCO3. The dissolution of carbonate substrates, such as coral reef frameworks and
sediments, under conditions of rising ocean temperatures and acidity in the water column has received much less
attention despite its potentially large effect on the carbon budget in these environments where dissolution could exceed
calcification during thiscentury. In this session, we plan to highlight current carbonate dissolution research being done
around the world pertaining to nearshore carbonate and coral reef sediments. We encourage submissions involving
research from a range of environments, under a variety of physical and chemical regimes and anthropogenic influence,
as well as laboratory modeling studies. In addition, we will emphasize studies that incorporate new techniques for
20 | P a g e
measuring and understanding reactions between the overlying seawater, porewaters, and solid-phase sediments within
the context of changing ocean carbon system chemistry under various CO2 emissions scenarios.

Session Title: The Dynamic Ocean Carbon Sink: Mechanisms, Variability and Trends
Session Description: Cumulatively since pre-industrial times the ocean has absorbed 40% of anthropogenic carbon
emissions, and thus has significantly modulated climate change. There is much yet unknown about the physical,
biological and chemical processes driving this uptake. There is also great uncertainty about the how ocean carbon
cycling will evolve over the coming century. This session will summarize the latest findings with respect to the physical,
biological and chemical mechanisms driving current and future changes in ocean carbon uptake, with both the solubility
and biological pumps being of interest. It will also address detectability of anthropogenic changes in the ocean carbon
cycle in light of large natural variability in the physical state of the ocean. Observational, theoretical and modeling
studies from all oceanographic disciplines are welcome.

Session Title: Marine silica cycle, silicification and silicifiers
21 | P a g e
Session Description: Silicification is a key biogeochemical process in the ocean and yet the extent of silicification
throughout the different domains of life, its evolution, and its role are questions that are yet to be resolved. This session
aims to address key questions related to the biogeochemical silica cycle of the world ocean, and to develop a
transdisciplinary approach (including chemistry, biogeochemistry, biochemistry, physiology, genomics) of silicification
processes and of marine silicifiers (pelagic and benthic diatoms, silicoflagellates, choanoflagellates, radiolaria, siliceous
sponges and potentially picocyanobacteria). The session will aim to contextualize recent advances in the ecology,
evolution, biology and genomics of silicifying organisms. In parallel, we will aim to cover advances relating to the
biogeochemical cycles of the two polar oceans as well as of that of coastal zones and of continental margins.

Session Title: From WOCE through CLIVAR to GO-SHIP: Results from Global Repeat Hydrographic Surveys
Session Description: For the past 25 years, countries from around the world have participated in obtaining multiple,
high-quality, repeat, global, hydrographic transects. The 1990’s World Ocean Circulation Experiment (WOCE) included
some 30 countries. It focused on improving our understanding of ocean circulation, heat and carbon transport through
the acquisition of a one-time global survey. The JGOFS program that sought to investigate mechanisms controlling
concentrations of inorganic carbon and associated biogeochemical parameters and fluxes augmented WOCE. Ten years
later CLIVAR began repeating transects focused on trends in ocean climate. The international Global Ocean Ship-based
Hydrographic Investigations Program (GO-SHIP) carries this task forward by identifying natural variability and
anthropogenic changes since WOCE.
In this session, we invite contributions using and interpreting these physical, chemical and biological observations. The
session will highlight research that presents and interprets changes that have occurred over the last 25 years using the
multitude of observed properties. A full range of contributions is solicited from surface to bottom waters based on
rosette, underway or float observations. All avenues of investigation are welcome, including those using related data, as
well as modeling and remote sensing studies performing comparisons and/or assimilations.

Session Title: Linking Optical and Chemical Properties of Organic Matter
Session Description: During the last decade there has been a substantial increase in the number of studies using the
optical properties (absorbance and fluorescence) of dissolved organic matter (DOM) as a proxy for its chemical
properties in freshwater, estuaries and the coastal and open ocean. As a result progress has been made on finding the
actual chemical compounds or phenomena responsible for DOM’s optical properties. Techniques such as ultrahigh
resolution mass spectrometry have played an important role. However much requires further study. Spectroscopic
measurements which are relatively easier to employ in synoptic and high resolution sampling of DOM distribution and
dynamics offer unique insight to major advances in our understanding of organic matter cycling in all aquatic
ecosystems. We invite talks and posters that specifically make connections between optical signals in absorbance and/or
fluorescence and biogeochemical properties of freshwaters (lakes, rivers), estuaries and the coastal and open ocean. We
encourage studies that describe DOM’s optical and chemical linkages at interfaces: terrestrial-aquatic, oceanatmosphere, benthic-pelagic, dissolved-particulate, water-sediment, etc. We also welcome contributions that utilize
remote sensing and in-situ monitoring to make connections between optical and chemical properties of organic matter.

Session Title: Nitrogen at the Interface: The N-Cycle across Physical and Disciplinary Boundaries
23 | P a g e
Session Description: Nitrogen availability is an important control on ecosystem dynamics in marine realms, from
oligotrophic gyres to eutrophic coastal waters. Assessing what controls the rates and distribution of N-cycling processes
is therefore of paramount importance for linking nitrogen biogeochemistry to productivity and ecosystem function.
Physical interfaces in the ocean are locations where the biology and chemistry of distinct water masses and sediments
interact, and appear to be hotspots for N-cycling. This session highlights nitrogen biogeochemistry at aquatic interfaces,
including oxic-anoxic transition zones, eddies/fronts, estuaries, and coastal/upwelling regions. Research on N-cycle
processes from unique marine interfaces and gradients of any kind is welcomed.
Furthermore, recent advances in our understanding of N-cycling have come from increasingly diverse research fields,
such as refined isotopic techniques, unique methods for modeling biogeochemical rates, and novel microbial analyses.
In addition to research located at physical interfaces, this session seeks presentations at the “interface” of traditional
oceanographic methods. Primary consideration will be given to presentations that incorporate techniques from multiple
disciplines, including (but not limited to) isotope geochemistry, microbial ecology, physical oceanography, and marine
ecosystem modeling. Therefore, this session will focus on integrating data and ideas across several oceanographic
disciplines to holistically understand N-cycling processes at marine interfaces.

Session Title: Physical and biogeochemical processes and the support of shelf sea primary productivity and carbon
cycling.
Session Description: An important challenge in oceanography is to understand how high rates of primary production in
shelf seas are sustained by supplies of nutrients, and to what extent the subsequent cycling and transport of fixed
elements may result in a net export of carbon to the deep ocean. The problem requires knowledge of the physical
processes that exchange water between the deep ocean and the shelf, and the role of riverine and atmospheric inputs
of nutrients. On the shelf we need to understand how biogeochemical cycling of elements (e.g. C, N, P, Si, oxygen, and
Fe) in the water column and sediments is driven by and affects shelf ecosystems (e.g. primary production, grazing,
plankton community structure, carbonate chemistry, remineralisation, development of episodic or seasonal hypoxia)
and to what extent carbon is exported from the shelf to the open ocean. Contributions are invited on the physics and
biogeochemistry of shelf-ocean exchange, riverine inputs to shelf seas, shelf biogeochemical processes, and air-sea
carbon and nitrogen fluxes in shelf systems, as well as conceptual or model-based research that draws the physics and
biogeochemistry strands together.

Session Title: Bypassing the Sediment-Water Interface: Burial and Diagenesis of Organic Matter and Reactive Minerals in
Quickly Depositing Sediments
Session Description: It is generally assumed that organic matter and reactive minerals (e.g., Mn/Fe (oxyhydr)oxides with
adsorbed P, Mo, Co, Cu, Ni) deposited at the seafloor undergo a well-defined and steady sequence of alteration,
including organic matter remineralization, mineral dissolution, element desorption, and authigenic mineral
precipitation. However, in near-shore, deltaic, or continental margin environments with extremely high or variable
sedimentation rates, organic matter and reactive mineral phases can bypass the sediment-water interface and are
quickly buried below the seafloor. Consequently, these deeper sediments function as biogeochemical reactors where, in
a semi-closed system, the primary composition of the sediments is altered long after its deposition: The degradation of
reactive organic matter, dissolution of minerals, and desorption of nutrients can sustain an active deep microbial
community which, in turn, enhances further deep biogeochemical element cycles due to the interaction between
microbes, minerals and surrounding pore waters. These diagenetic reactions result in permanent changes to the original
sediment composition, overprinting paleoceanographic proxy records and biasing climate reconstructions. This session
invites contributions that study such sub-surface microbial and geochemical processes, and/or their effects on the
primary sediment composition, in marine environments with high and/or variable sedimentation rates.

Session Title: Physical-biogeochemical coupling in oceanic eddies and fronts: from submeso- to mesoscale processes
Session Description: Eddies, fronts, and upwelling systems are ubiquitous features with essential contributions on
disturbing and transporting materials and energies in the global ocean. Physical and biogeochemical processes in these
systems have been long recognized as “dynamically active” that are typically different from basin-scale adjustments.
With recent advancements in in-situ monitoring, remote sensing and high-resolution numerical models, physicalbiogeochemical coupling in these systems indicates prominent spatial and temporal variability that could be potentially
related to the nature of mesoscale and submesoscale dynamics. Systematic understanding of the underlying dynamics is
required to better interpret observed ocean biogeochemical variations, which can further advance the understanding of
global carbon cycle and ultimately climate change. Both observations (in situ and satellite) and numerical models are
able to provide clues to how these dynamics affect ocean biogeochemistry from nutrient cycling to ecosystem
structures, as well as how ocean biogeochemistry evolve with mesoscale and submesoscale dynamics. In this session, we
welcome contributions from any discipline that examine topics about physical-biogeochemical coupling related to
mesoscale and submesoscale dynamics from snapshots to long-term temporal scales. Researches that address impacts
of eddies, fronts, and upwelling systems on biological, chemical, and high-trophic level processes are particularly
encouraged for submission.

Session Title: Anthropogenic impacts on upper ocean biogeochemical processes
Session Description: Anthropogenic activity modifies environments and influences ecosystems and biogeochemical

ecosystems where multiple stressors can result in changes that are non-linear, with responses to pressures being
additive, antagonistic or synergistic. Climate change, due to the increase in atmospheric concentrations of radiative
26 | P a g e
trapping gasses, is one of the most recognized pressure to affect ecosystems. However other anthropogenic-mediated
activities, such as the input of the organic and inorganic nutrients from riverine and atmospheric sources, nutrient- and
toxin- containing effluents from oil and gas exploitation and marine transportation and the deposition of black carbon
can also influence ecosystem and biogeochemical processes at varying scales. Ecosystem services, such as upper ocean
primary and secondary production, microbial activity and biogenic carbon fluxes, including the ocean carbon pumps that
sequester carbon and mediate climate change, are potentially influenced by these human inputs. This special session
will bring together researchers that use a range of techniques, including observations, experimental and modelling
approaches to characterize and assess the cumulative effects of anthropogenic activities on ecosystem services with the
objective of better understanding their interactions with and responses to environmental forcings.

Session Title: Scaling up microbial and foodweb processes to global biogeochemical fluxes
Session Description: The structure and functioning of the marine microbial foodweb influence valuable ecosystem
services such as the marine storage of carbon, and hence mediate climate. Predicting how ecosystems might respond to
environmental change and the consequences of this for human systems relies on process understanding across a range
of molecular, microbial, physical, trophic and biogeochemical spatial and temporal scales. Estimation of carbon, oxygen
and nitrogen biogeochemical cycles requires an appreciation of the scaling rules connecting cellular metabolism to
global inventories and fluxes. However, the empirically derived or assumed scaling rules to make these conversions are
rarely discussed or tested, despite the frequent mismatch between measurements and models made over different time
and space scales (e.g. microbe, aggregate, seawater, mixed layer, shelf sea, ocean basin). This session invites
contributions which compare and contrast measurements and models of plankton metabolism and resultant
biogeochemical fluxes with particular emphasis on challenging the approaches used to scale up from the microbial to
global scale. Contributions are also encouraged which propose ways of highlighting the concept of time and space scales
in microbial oceanographic education and outreach.

Session Title: Nutrient Enhanced Coastal Acidification and Hypoxia
Session Description: Excessive nutrients often cause hypoxia through enhanced phytoplankton production of organic
matter that is exported to the bottom and consumed by microbial respiration. The released CO2 during respiration
further reduces the pH of already acidified water due to atmospheric CO2 in a way that is more than additive. This is a
concern due to the deleterious effects of low pH and O2 on marine life. Yet, factors regulating coastal acidification are
not fully understood due to the complexity of coastal systems. One complication is caused by benthic respiration which
reduces O2 and pH, but also generates alkalinity (via anaerobic processes), which buffers against rapid changes in pH.
The oxidation of reduced species could also reduce pH near the oxic-anoxic boundary. These and other biogeochemical
processes, along with stratification and end-member mixing influence the occurrence and location of ecologically
relevant combinations of low pH and O2. However, the uncertainties around these processes make the effectiveness of
management efforts aimed at nutrient reductions to reduce coastal acidification difficult to predict. This session invites
presentations describing observations and models that further understanding of and improve our ability to predict how
nutrients and other anthropogenic impacts contribute to coastal acidification and hypoxia.

anthropogenic contaminants. We invite papers on any biogeochemical aspect of sediment resuspension in coastal
marine and aquatic environments. In particular we encourage contributions on how these processes might be influenced
by factors such as photochemistry, global climate change (e.g. rising sea level), and land use changes.

Session Title: Understanding and predicting the marine nitrogen cycle: from microbes to the global ocean
Session Description: The oceanic fixed nitrogen (N) inventory exerts a significant influence on the biosphere by
controlling marine productivity and affecting climate relevant gases such as CO2 and N2O. Despite significant advances
in understanding the marine N cycle over the past decades, there are still large uncertainties in how the N inventory is
regulated by physical processes and by biogeochemical interactions with C, P, Fe, and O2 and how it is affected by
anthropogenic activities. In this session, we invite contributions on the regulation of the marine N-cycle, including N2
fixation, denitrification, nitrification, and N2O production. We welcome studies that use diverse biogeochemical
approaches (such as stable and radiogenic isotopes, trace elements, biomarkers, and modelling) and that cover diverse
spatial and temporal scales, including those that focus on the current, past and future ocean. We hope this session will
foster a multidisciplinary exchange on the drivers of and future changes to the N cycle.

Session Title: New Orleans 30 Years On: What’s the Future for the Marine Nitrogen Cycle?
Session Description: New developments in nitrogen biogeochemistry were the subject of a session at the Ocean
Sciences Meeting thirty years ago. Since then there have been many unexpected discoveries and new tools have been
developed not only for studying the nitrogen cycle, but also for integrating the nitrogen cycle with other biogeochemical
cycles and for extrapolating over space and time. This session will cover all aspects of the nitrogen cycle, from
unanswered questions remaining from 3 decades ago, to newly discovered processes and features of nitrogen cycling in
the global ocean. Speakers will be encouraged not only to talk about their recent work and discoveries, but to reserve
time and present a slide on what they see as the future important and significant questions for understanding the global
ocean nitrogen cycle, its biogeochemical interactions and impacts of global climate change.

Session Title: Wayne’s World: A Session to Celebrate the Career of Wayne Gardner and his Broad Contributions to
Understanding the Biogeochemistry of Aquatic Systems
Session Description: “Ocean Sciences at the Interface” describes Wayne Gardner’s career, spanning over 50 years with
work from Lake Mendota to the Gulf of Mexico, Taihu Lake to the hypersaline Laguna Madre (Texas). “Wayne’s World”
includes many topics, from humic and amino acids to PAHs, the microbial food web to nitrogen cycling, and has
transformed our understanding of eutrophication, hypoxia, algae blooms, and nutrient cycling in aquatic environments.
As Wayne charges into retirement, but remains active scientifically, it is time to celebrate his remarkable career. The
venue is ideal given his extensive work in the Gulf of Mexico. We invite investigators to present their work in the context
of Wayne’s vast web of influence. We seek contributions from investigators inspired in any way by Wayne’s body of
work, studying biogeochemical mechanisms in the locations where he has worked and/or are studying aspects of the
nitrogen cycle common to his most recent work. The session would hopefully conclude with a tutorial presentation by
Dr. Gardner. We have had preliminary discussions with several investigators, and initial interest is very strong. We
anticipate a minimum of 20-30 abstract submissions, and probably more.

particles (Honoring Cindy Lee’s retirement)
Session Description: Marine particles are key components in element cycling and organic matter transport in marine
environments. As one of the leaders in the field of marine organic geochemistry, Cindy Lee has made significant
contributions to our understanding of marine particle cycling, including production, decomposition, and sinking flux to
the deep ocean. Her work has greatly advanced our knowledge on diagenesis of sinking particles during the transit to
the deep ocean, interaction of organic matter with minerals, formation and distribution of marine transparent particles,
as well as the impact of ocean acidification on the fate of marine particles. In honor of her retirement, we invite
abstracts that deal with different perspectives on biogeochemical processes of marine particles in both eutrophic and
oligotrophic marine waters.

Session Title: Elemental Ratios as Tracers and Drivers of Plankton Biodiversity and Biogeochemical Function
Session Description: Microbial life in the ocean contains immense biodiversity, yet its collective activity yields global
cycles of key nutrients that are tightly linked. Recent studies have demonstrated the potential for large-scale variation in
nutrient uptake ratios, and the influence of nutrient ratios on plankton biodiversity and ocean biogeochemical
functioning. This session will bring together experimentalists, theoreticians, and modelers from a range of disciplines
with a goal to understand (1) how elemental ratios can be used to understand the coupling of major elemental cycles,
(2) mechanisms leading to different ratios of nutrients in ocean water or plankton, or (3) the influence of elemental
ratios on plankton physiology, biodiversity, and distribution. We invite studies that utilize novel culture, field, theory,
and/or modeling approaches to address these questions.

Session Title: Updates, Advancements and Projections on the State of the Ocean Carbon Cycle (SOCC) - How the Ocean
is "SOCC"ing it to us!
Session Description: The global ocean is a major sink of anthropogenic carbon dioxide (CO2), significantly slowing the
accumulation of this important greenhouse gas in the atmosphere. The physical, biological, and chemical processes and
exchanges that occur in and across ocean and atmosphere represent a major control on ocean CO2 uptake. This session
will feature new observations, process studies, and modeling advancements that further our understanding of the
carbon cycle in the ocean and its connection to ecosystems and climate. Spanning regions of the ocean dominated by
coastal and equatorial upwelling, deep convection, mesoscale eddies, etc., this globally expansive session will include
presentations that highlight the strong connection between the ocean carbon cycle and the climate, focusing on physical
dynamics, chemistry changes (e.g., ocean acidification), and biological responses and feedbacks.

Session Title: Beyond Redfield - Updating Biogeochemical Stoichiometry in a Changing Ocean
Session Description: Almost 80 years ago, A.C. Redfield discovered that relatively invariant elemental ratios found in
marine organisms are intimately entwined with the co-variation of these elements in the ocean. These ratios are key to
the ocean’s ‘biological pump’ that links nutrient and carbon cycling and is recognized as an important control on
atmospheric CO2 and thereby Earth’s climate. However, since Redfield’s time, a broad divergence in perspective has
developed. Biologists tend to view organisms, particularly autotrophs, of having some measure of plasticity in their
cellular stoichiometry. In contrast, geochemists tend to view Redfield stoichiometry as a fixed property of marine
systems, an assumption that is reflected in both data interpretation and model simulation. These contrasting views lead
to sharp differences in understanding of nutrient limitation, the regulation and evolution of biogeochemical cycles, and
the interaction between organisms and their chemical/physical environment. There is a growing realization of the need
to merge these perspectives fueled by new analytical and experimental techniques as well as modeling approaches.
This session will solicit oral and poster presentations from researchers across these different communities and topics
with the goal of achieving a new synthesis regarding biogeochemical stoichiometry in the ocean and its application to
key questions.

Session Title: Plankton food webs and the efficiency of the biological pump
Session Description: Predicting the impact of anthropogenic forcing on the biological pump requires understanding the
various processes concomitantly affecting export, including gravitational flux of particles, active vertical migration by
mesozooplankton and micronekton, and the production of refractory carbon by microbial communities. These are all
ultimately related to plankton structure and trophic efficiency of the grazer community. A mechanistic understanding is
limited by the lack of simultaneous measurements of carbon export, trophic structure, specific phytoplankton
production rates and energy transfer through the plankton food web. However, our ability to assess planktonic
ecosystem trophic efficiency is increasing rapidly. Compound-specific isotope analyses allow detailed estimates of food
web structure, triple oxygen isotopes and oxygen:argon ratios can determine net:gross production, combinations of in
33 | P a g e
situ grazing with pigment, molecular, and isotopic tools allow estimation of group-specific consumption rates, various “omics” tools help determine the distribution and activity of organisms with specific biogeochemical roles, and modeling
advances allow comparisons to be made across different ecosystems and ecosystem states. We invite presentations
that couple such novel investigations of the efficiency and character of the plankton to the strength of the biological
pump, particularly those comparing multiple ecosystem states in which export is measured simultaneously with
different trophic structures.

Session Title: The role of particles in the cycling of trace elements and their isotopes in the ocean
Session Description: A number of trace metals are thought to control marine ecosystem features and biological
productivity. While trace elements in the dissolved phase have been the focus of many investigations, we are still largely
ignorant of the large scale distribution of particulate trace elements and their size partitioning and chemical
composition. The GEOTRACES program, which aims to provide a comprehensive view of the distribution of trace
elements and their isotopes (TEIs) in the world's oceans, is providing new insights on these aspects. Furthermore, there
is a crucial need to understand the exchange mechanisms between particulate and dissolved pools, including
adsorption, desorption, aggregation, precipitation, biological uptake and remineralization processes. This session seeks
to bring together scientists interested in better constraining the role of ocean particles in the biogeochemical cycles of
TEIs, in different oceanic environments, such as the continental shelves and slopes, the nepheloid layers, or the particlepoor regions of the open ocean. We invite abstracts on all aspects of oceanic particulate TEIs, through experimental, in
situand modeling approaches.

Session Title: Trace Metal Bioavailability and Metal-Microorganism Interactions
Session Description: The distributions of trace elements in the marine environment are undeniably linked to biological
processes. Low concentrations or low bioavailability of trace metals in the water column can lead to micronutrient
limitation and stress, while greater availability may increase biological demand and enhance the growth of
microorganisms. Recent advances in high throughput biological techniques, including “omics”, as well as high-resolution
geochemical data from the GEOTRACES program (www.geotraces.org) has lead to a wealth of new data. However,
meaningful interpretation of these data often still relies on process studies, incubation-based experimental work, or the
culturing of representative or novel organisms. This session invites contributions on every scale of metal-microorganism
interactions, ranging from small-scale mechanistic work to large-scale biogeochemical cycle studies. We encourage
abstracts that investigate trace metal acquisition strategies, cellular metabolism, chemical speciation and bioavailability,
and/or studies that link trace metal and biological water column data. Presentations that strive to better understand the
biological control exerted on the distribution of trace elements in the marine environment are especially encouraged.

Session Title: Integrating approaches to understanding the distribution and transfer of trace elements in the upper
water column
Session Description: Micronutrient cycling in the upper water column involves a complex interplay of physical, chemical
and biological processes operating in concert. Thus, by nature, the study of micronutrient cycles is interdisciplinary.
Resolving these processes can be challenging, but the combined use of observations, experiments and models has led to
the better understanding of biogeochemical cycling of trace elements and their isotopes (TEI). In recent years there have
35 | P a g e
been significant advances in analytical capabilities, and there are a number of ongoing large-scale field programs (such
as GEOTRACES, AMT, and CLIVAR) that provide the perfect platform for conducting basin-scale studies of this nature. We
invite presentations that take interdisciplinary, integrated approaches to quantify micronutrient fluxes and
transformations in the upper water column, with a focus on geochemical interactions. Submissions are encouraged from
field studies, laboratory-based investigations and modelling studies in order to assess state-of-the-art applications and
future direction for TEI studies.

Session Title: Trace Elements and Isotopes at the Interfaces of the Atlantic Ocean
Session Description: Trace elements play a crucial role in the ocean. Some are toxic at high concentrations, others serve
as essential micronutrients in the many metabolic processes active in marine organisms. Some trace elements and their
isotopes (TEIs) are diagnostic and allow the quantification of specific oceanic mechanisms. Studying the biogeochemical
cycles of TEIs is thus necessary to deepen our understanding of carbon and nutrient cycling, climate change, ocean
ecosystems and environmental contamination. The Atlantic Ocean is one of the primary CO2 sinks of the world ocean
and one of the most biologically productive. Recently, full-depth high resolution measurement campaigns, especially in
the framework of the international GEOTRACES program, have revolutionized our understanding of the TEI cycling in the
Atlantic Ocean. However, processes occurring at the oceanic interfaces are very complex and need more attention. The
aim of this session is to increase our understanding of the exchange of TEIs at the interfaces between the ocean and i)
the atmosphere, ii) the continents (e.g. by rivers and groundwater), iii) the marine sediments, and iv) the ridges. We will
particularly encourage contributions dealing with interdisciplinary studies, with new insights gained by application of
state-of-the-art analytical tools and modeling approaches.

Session Title: Modelling of Chemical Speciation in a Changing Ocean
Session Description: Global change processes, in particular ocean acidification, are changing the chemistry of seawater
throughout the world. The carbon dioxide system and trace metals are expected to be among the chemical components
of seawater to be most strongly affected by global change processes. Chemical speciation modelling plays an important
role in understanding the changes that take place and in projecting future changes. This has been recognised by SCOR in
establishing Working Group 145: ‘MARCHEMSPEC - Modelling Chemical Speciation in Seawater to Meet 21stCentury
Needs’. One aspect that is receiving particular attention in this respect is the bioavailability of trace metals, where
extensive measurement programmes on the complexation of bioactive trace metals are currently under way, in
particular within GEOTRACES. Interpretation of these measurements does, however, include a substantial component of
speciation modelling that would benefit from more accurate input data and less simplified data treatment. Important
applications are not confined to trace metals: for example ongoing ocean acidification highlights the need for accurate
descriptions of aragonite and calcite solubilities under changing conditions. This session provides an important
discussion forum in a subject area that plays a central role in understanding the consequences of global change for
marine systems.

Session Description: To complement the overall theme (Ocean Sciences at the Interface) of this ASLO conference, we
invite presentations on research that involves the utilization of tracers such as fatty acids or stable isotope ratios to
address questions about trophic ecology at oceanic interfaces. Relevant ecological interfaces may include those formed
by the meeting of sediment and water, land and sea, sea and air, sea and estuary, converging currents, etc. In expanding
our knowledge on the trophic connections across boundaries, we will better understand the broader topic of
connectivity in the world’s oceans. We invite seminars that a) utilise one or more tracer methods to address some
37 | P a g e
aspect of trophic ecology (ranging from microbes to mammals) involving interfaces, and b) improve our knowledge of
the larger implications of trophic connections between oceanic habitats.

Session Title: The biogeochemistry of dissolved organic matter (DOM)
Session Description: Dissolved organic matter (DOM) plays a major role for biogeochemical cycles in the ocean and on
land. DOM contains as much carbon as all living biomass on the continents and oceans combined, and a similar amount
of carbon as atmospheric CO2. Due to its great size, even minor changes in the DOM pool will impact global
biogeochemical cycles and the heat budget of the Earth. The accumulation of DOM in the ocean over several millennia is
enigmatic and contradicts established paradigms in geochemistry for organic matter stabilization. On the other hand,
bacteria can only assimilate dissolved molecules, and DOM is therefore the main mediator for the flux of energy in the
ocean and freshwater ecosystems. The DOM pool is now recognized as paralleling the sedimentary record as an
information-rich set of tracers. These molecules carry the signatures of their source and subsequent journey through the
environment. For this session we invite contributions from all areas of research on DOM biogeochemistry. Molecularlevel studies and interdisciplinary studies that link microbiological or abiotic processes to DOM cycling are particularly
welcome. Also contributions that identify novel concepts, fundamental challenges, and the future directions of this fast
growing field of research are encouraged.

Session Title: Linking marine microbes and the molecules of dissolved organic matter through data science
Session Description: Dissolved organic matter (DOM) in the ocean comprises one of the largest reservoirs of reduced
carbon on Earth, and it provides an important base for microbial life in the water column. The interactions of DOM
molecules and marine microbes are of crucial importance in the cycling of carbon and other elements. The application of
emerging analytical techniques now routinely provides information on DOM composition and microbial communities in
unsurpassed detail. Linking chemical and microbiological information is an important step for understanding DOMmicrobe interactions on a molecular, and potentially mechanistic, level. Vast amounts of new data are generated in
molecular biogeochemistry; merging and mining these complex data sets poses a significant challenge to all researchers
in the field. Computational tools developed in bioinformatics have proven value in related research areas and have
immense potential to facilitate novel insights in microbe-DOM interactions within the ocean sciences. This session will
bring together organic geochemists, microbial ecologists, and informaticians with research interests at the intersection
of microbiology and DOM biogeochemistry.

Session Title: Kinetics: the force driving trace metal distributions in marine waters
Session Description: Kinetics, sensu lato, play a key role in controlling concentrations of trace metals in marine waters
and thereby shape their distributions. Trace metals undergo a range of kinetically controlled reactions with dissolved
and particulate organic and inorganic compounds in seawater. The emerging results from the International GEOTRACES
campaign illustrate more uneven distributions of many trace metals and isotopes in the world’s ocean than expected.
Our understanding of the kinetic supply and removal processes is clearly underdeveloped. Quantitative information on
the kinetics of the processes involved in trace metal cycling is required to parametrise biogeochemical processes in
regional and global ocean models. This will then allow us to interpret the elemental distributions in emerging
39 | P a g e
GEOTRACES sections. We invite submissions on the kinetics of trace metal cycling in the ocean, the formation and
dissociation kinetics of organic complexes and inorganic colloids, the kinetics of uptake and release of trace metals by
bacteria, phyto- and zooplankton, kinetics of the trace metal release by the microbial decomposition of organic material,
the kinetics of metal redox processes, the loss of trace metals by scavenging and sinking, and modelling approaches that
require parameterisation of kinetics for a more realistic view of ocean biogeochemistry.

Session Title: Ligand Concentrations and Composition for Metals Speciation in Ocean Waters
Session Description: Metals in seawater are presented with a myriad of possible reactions. The consensus is that
biogenic metals occur as organic species. These reactions (the chemical speciation) determines the route of uptake by
biota and whether the biota can take active or passive steps to improve its survival. In spite of the importance of the
ligands, there is no consensus as to which is the dominant ligand, and instead, ligands are classified as strong or weak, as
L1 or L2 (or more). This fits in well in the coming Ocean Sciences meeting as the speciation controls the important
reactions at the interface of microbes and scavenging particles. We are looking for contributions in the area of metal
complexation, the nature of the complexing ligands, and their effects on metal chemistry.

Session Title: Sources and Sinks of Reactive Oxygen Species in the Ocean:“Is seawater a radical solution?” (Zafiriou,
1987)Revisited.
Session Description: The formation of reactive oxygen species (ROS; e.g. H2O2, O2−, ŸOH, and 1O2) via photochemical
reactions has long been known to be ubiquitous in marine waters. These species help poise the chemical redox state of
the ocean and can have mixed impacts on marine macro- and micro-organisms. Surprisingly, good, basic in
situmeasurements are still lacking for all ROS but H2O2. Recent reports of ROS production by healthy and diverse
microbes, particularly superoxide and hydrogen peroxide, create new questions as to the relative role of photochemistry
and biology in ROS cycles and complicate assumptions about production pathways. In addition, new studies challenge
the assumption that ROS are simply a suite of detrimental metabolic byproducts, and call for a re-examination of the
impacts, feedbacks, and physiological role(s) of ROS in living systems. In the end, the magnitude and relative importance
of abiotic and biotic ROS sources and sinks in the ocean remain poorly understood. This session seeks contributions
covering all ROS sources, sinks, mechanistic processes and distributions in marine systems. Integrative studies that
quantify ROS dynamics and impacts are particularly encouraged.

Session Title: Sharing Ship-Based Ocean Research Through Innovative Technology and Hands-On Vessel Experiences
41 | P a g e
Session Description: Sea-going research vessels are increasingly devoting resources to bringing real-time experiences to
shoreside researchers, students, and the broader public. Bridging remote field research between scientists at sea and
the worldwide learning community has become a successful tool for exposing a variety of career pathways in the marine
sciences and engaging new and underrepresented audiences by broadening public outreach and learning capacity.
This session will highlight ship-based education and communication programs aimed at student and public participation
in the marine sciences, constructed through technology and participatory experiences. Emphasis will be on expanding
engagement with successful programs that conduct oceanographic research and exploration using telepresence, live
data and video streaming, and other forms of ship-based research activities involving shore-side researchers, students,
and general public. Presentations may explore lessons learned, strategies, challenges, and future directions for
strengthening education-focused oceanographic shipboard programs.
Examples of topics highlighted in this session may include student mentorship, scientist engagement, authentic research
experiences, telepresence and remote science, and other similar types of online programs that reach and captivate
broad audiences.

Session Title: Ethical principles and practices in the Ocean Sciences
Session Description: Geoethics is an interdisciplinary study that encompasses professional ethics and scientific integrity,
stewardship, and risk communication. As such, Geoethics provides a valuable framework for exploring our ethical
obligations as ocean scientists in a variety of settings. As scholars and experts, we have an obligation to not only conduct
research responsibly but also to inform society of potential marine resources and hazards. For example, ocean scientists
are uniquely suited to address such issues as tsunami warnings, overfishing, iron fertilization, and ocean pollution,
informing science-based management and policy decisions. As educators, we also have an obligation to train our
students in ethical practices and principles. The goal of this session is to discuss these obligations through presentations
that highlight case studies at the interface of marine science and ethics, as well as educational strategies for
incorporating Geoethics into undergraduate and graduate curricula.

Session Title: Innovations in Environmental and Ocean Science Education
Session Description: Environmental and ocean science incorporates the life sciences, the physical sciences, and the
Earth sciences. Traditionally, it has been taught in disciplinary and multi-disciplinary curricula, but new approaches have
relied on hands-on learning, project-based learning, instructional technology, flipped classrooms, and Earth system
science approaches. Innovative ideas are embedded in a variety of marine, environmental, and natural science
programs, formal courses, and other activities and delivered by a great diversity of instructor. This session welcomes
innovative approaches to teaching environmental and/or ocean sciences in grades 5-20 (middle school, high school,
community college, university, graduate school). An emphasis will be placed on evidence for effective teaching and
learning.

Session Title: Integrating Ocean and Climate Science Education: Preparing the Next Generation of Scientists and Citizens
Session Description: The foundation for understanding, studying, and managing many of the most pressing current
global issues must be built on knowledge of the complex relationships between the ocean and climate. Interdisciplinary
preparation is essential, and 21st century oceanographers and climate scientists can no longer work exclusively within
their own disciplines. Moreover, the ocean and climate sciences workforce is increasingly active in addressing problems
of critical importance to society, such as improving the forecast accuracy for tropical cyclones and increasing coastal
resilience. There is an urgent need for young investigators who can not only address questions related to the
interactions of ocean processes with the atmosphere, land, and ice systems, but also work collaboratively outside of
43 | P a g e
academia and communicate with non-scientists to identify strategies for mitigating and adapting to global changes.
Beyond scientific research, national efforts to address Earth’s changing systems must include ocean and climate science
education. This session focuses on initiatives that highlight the intersection of higher education, scientific research, and
the communication of science. Scientists, education professionals, learning scientists, and evaluators are invited to share
their designs, implementation strategies, and/or evaluation results related to interdisciplinary programs.

Session Title: Teacher-Researcher Partnerships: working at the interface of science and education to enhance student
learning
Session Description: Future scientists grow from children who discover a love of science as students, often because they
were inspired at some point by an amazing science teacher. These science teachers can find inspiration and support by
working directly with researchers in the field. Current research on science education emphasizes the need for multiple
ways to engage students with scientific inquiry. Partnerships between research scientists and classroom teachers
provide authentic experiences that can also engage students in scientific practices and application. Teachers who
experience research first hand can become better science educators. Researchers can benefit by having their science
translated to a broader audience. Developing and sustaining effective and reciprocally beneficial teacher-researcher
partnerships can be difficult yet transformational for both parties. How do you make research relevant for target
audiences? How do you sustain those collaborations between researchers and educators? How can the scientific
community support these partnerships in the future? We invite successful partnerships between researchers and
educators, as well as researchers and teachers intrigued by the idea, to share their ideas and experiences. In a world
where science and ocean literacy is increasingly vital, involving teachers, students, and their families in scientific inquiry
has never been more important.

Session Title: Innovative Informal Learning for Improving Environmental and Ocean Science Literacy
Session Description: All communities including coastal and land-locked areas are affected by the ocean. As the ocean
change, so do local environments. Once people leave formal K-16 education, how do they learn about relevant and
important environmental issues in their communities? Informal science education provides a creative, accessible, and
interdisciplinary means of engaging adults with opportunities to learn about their changing climate. Traditionally
conceptualized as nature centers, zoos, aquariums, and science museums; informal science education is broadening its
reach by finding new and innovative ways to provide learning opportunities for the general public. This session will
focus on how different disciplines can come together to engage the public and promote the understanding of
environmental and ocean sciences through such efforts as Place Based Learning, Out-of-Home-Media, Social Networks,
Virtual Expeditions, Art in Science, and Citizen Science. A special emphasis will be placed on innovation and creativity in
science communication.

Session Title: Using Informal Science Programs to Connect Ocean Science to the Public
Session Description: As much as 90 percent of learning takes place outside the classroom and through lifelong learning
opportunities – such as museums, aquaria, film, video, books, music, art, lectures and much more. Using innovative
informal science techniques and tools, ocean scientists and educators are reaching out to the public to raise awareness
and knowledge of ocean topics in new and interesting ways.
This session will focus on cutting-edge and creative STEM programming aimed at families and the general public outside
the classroom. We invite presentations highlighting interactive experiences and multimedia that engage the public on
highly relevant ocean topics. Presentations may include examples of successful programs, evaluation studies, challenges,
partnerships between scientists and educators, new resources and upcoming opportunities. Topics may include
45 | P a g e
interactions between formal and informal programs, strategies that reach large numbers of people, the pipeline and
training for marine informal science educators, the impacts of particular programs, exciting uses and potential of new
technology and social media, connections between science and art, techniques for reaching traditionally underserved
audiences, and many other related programs.

Session Title: Creative Ways to Enhance Ocean Literacy - Marine Research Meets Art
Session Description: Recent findings in marine research, advances in marine technology, and marine conservation
efforts are hot topics that may be used to enhance ocean literacy. Manifold outreach activities link such topics with a
life-long learning concept and address audiences with or without scientific backgrounds. Designing adapted activities
starts an exciting process, which is as challenging as reaching out to new audiences. And good outreach, just like cuttingedge marine research, requires a great deal of creativity. One way of injecting new creativity into marine science
outreach is to connect creative people from outside this “researcher–outreacher” environment. This session seeks to
highlight inventive ways to outreach from all those who connect scientific and artistic creativity and/or work at the
interface of research and arts. For example, researchers and science communicators may present their experiences in
introducing marine topics in plastic art classes within school environments or at specific events dedicated to artists.
Experiences and outcomes in visual arts, literary and performing arts, or with new streams (e.g. serious/educational
games) are welcome. Contributions to this session may also evidence a dialogue between dissimilar groups as well as
the strength of artistic expressions to link marine research with impacts e.g. on societal backgrounds.

Session Title: Graduate Student Outreach: Students at the Interface of Their Ocean Science Career
Session Description: Graduate students represent the interface of between education and the workforce in ocean
science, whether it be academia, research, education or other related careers. In addition to intense hours in the lab and
seemingly never-ending fieldwork, many graduate students are also involved in education/outreach to broader
audiences. Graduate students are generally isolated with much of their collegiate interaction being with their advisor,
who may or may not encourage educational outreach in addition to a strong focus on research during their graduate
careers. This session will be run for graduate student presenters with all graduate student co-chairs and aims to give
students an opportunity to present any education and/or outreach activities with which they are involved such as afterschool programs, science fairs, social media platforms, science cafes, etc. Any abstract to this session will not prohibit
the presenter(s) from also presenting in a research session.

Session Title: Ocean science education: Collaborations, partnerships, and activism
Session Description: Nearly half the global population lives in or near coastal regions. Along with increasing population,
the percentage of people living near coastal regions is expected to rise dramatically in coming years, increasing
anthropogenic pressure on inland waterways and the ocean. Despite this, community knowledge and understanding of
the ocean is often limited. For example, in the United States, people of all ages are relatively unknowledgeable about
the ocean (Ocean Project, 1999, 2009), particularly when considered holistically. With only a small percentage of the
population having regular access to the marine environment, and less than 10 percent of science education curricula
focused on the ocean, where do youth gain the knowledge and experiences they need to gain respect and find value in
the marine environment in order to act for conservation and better resource management? Further, how do scientists
use their position to educate youth and the population in general? This session highlights the value of marine and
aquatic science education and the importance of the role and interaction of ocean scientists and science educators to
act as catalysts for youth activism and civic engagement for ocean-related issues. Both US and international perspectives
are welcomed.

Session Title: Nearshore Processes ..............................................
Session Description: The nearshore region is a dynamic environment shaped by interacting processes encompassing
different spatio-temporal scales and the complex feedbacks between wind, waves, currents, and morphology. The
susceptibility of this region to sea level rise and climate change constitutes a major concern for society. We invite
abstracts that focus on the physical processes occurring in the nearshore region from the beach face to the shelf break.
Topics of particular interest include: 1) surface and internal waves 2) riverine, tidal, wind and wave driven currents, 3)
mixing and turbulence, 4) non-cohesive/cohesive sediment transport, 5) morphodynamics, 6) beaches, barriers, tidal
inlets and river mouths. We welcome a range of presentations covering field observations (both remote sensing and insitu), numerical and laboratory modeling, theoretical analysis, and model-data assimilation. The nearshore processes
session is a well-established and well-attended session in which student participation is strongly encouraged.

Session Title: Coasts in Crisis: Sea Level Rise, Inundation Mechanisms and the Need for Adaptation
48 | P a g e
Session Description: Sea-level rise, a dominant driving force of coastal change, along with altered wave conditions,
storm intensity and ocean circulation patterns, is increasingly evident and important as a persistent and long term
hazard worldwide. Geologic records show sea level has been as much as ~8 m higher and ~130 m lower than today. Sea
level was stable for the past 3000 yrs until the mid-19th century, but during the 20th century sea level began rising at a
global average rate of ~1.7 mm/yr. The current average global rise rate is ~3.1 mm/yr. Sea-level rise, with high regional
variability, is expected to continue for centuries, with rise of 0.5- 2 m predicted by 2100. With this is the expected
increase in enhanced coastal storm and inundation activity – further enhancing flooding and coastal damage. Adaptation
planning is advisable with reliable and validated models for predicting future coastal change and inundation. Papers
invited for this session include: the impacts of sea-level rise, storms, waves on coasts; field and numerical model studies
of storm surge, waves and inundation predictions and effects; links between warming and sea-level rise; assessments of
coastal impacts; examples of adaptation; investigations of coastal elevation and change; and case studies.

Session Title: Advances in Coastal Hypoxia Modeling: From Physics to Fish
Session Description: Hypoxia (< 2 mg O2 L-1) has been reported with increasing frequency from a variety of coastal and
estuarine ecosystems. Hypoxia develops as a result of complex interactions of physical and biological processes, which
often cannot be fully understood through observations alone. Numerical models are an important research tool that can
be applied to understand the processes that determine the spatial and temporal variations in hypoxia. This session is
devoted to diverse modeling approaches, including mechanisms controlling hypoxia development, anthropogenic and
climatic influences on hypoxia, and the ecological effects of hypoxia on regional ecosystems. Studies may consider the
causes, processes, effects or prediction of hypoxia, and focus on physics and/or biology, including fish. Applicable
models range from purely empirical to complex three-dimensional models.

Session Title: Physical and Biogeochemical Processes at the Sediment-Water Interface in Estuaries, Coastal Oceans and
Shelf Seas
Session Description: Benthic processes and the resulting fluxes at the sediment-water interface are highly significant in
the shallow waters that characterize estuaries, coastal oceans and shelf seas. Many physical and biogeochemical
processes influence benthic-pelagic exchange, and near-bed fluxes and transport of sediments, nutrients, carbon and
other bioactive solutes. Sediment resuspension and bed reworking by tides, waves, and biological activity are frequent
in the energetic coastal environments considered. Dissolved material can be exchanged by diffusive and
pumped/advective processes. The interactions between the flows and large and small scale seafloor morphology are
complex and can modify flux rates. Particulate matter settles and accumulates in an unconsolidated fluff layer easily
remobilised by bottom currents. Our understanding of these processes nevertheless remains limited to date, and fully
elucidating the benthic-pelagic exchanges requires approaches encompassing biology, chemistry, physics, and the
interactions and feedbacks between them. This session seeks contributions across these disciplines which directly
address processes affecting cycling and fluxes at the sediment-water interface and in the near-bed boundary layer in
estuaries, coastal oceans and shelf seas. This session will welcome studies based on in-situ observations, laboratory
experiments, and modelling either resolving or parameterizing processes.

Session Title: On the use and challenges of applying remote sensing in coastal waters
Session Description: The use of remote sensing data, including ocean color (chlorophyll), sea surface temperature (SST),
and sea surface winds over the last two decades has significantly advanced our understanding of large-scale oceanic
processes. However, there are a number of issues and challenges with using remote sensing data in coastal areas.
Coastal areas are much more dynamic than the open ocean, and the spatial, temporal and spectral resolution of current
satellite sensors is often inadequate to properly characterize them. The standard chlorophyll algorithms for ocean color
sensors do not work well in optically-complex (Case-2) coastal waters. Present methods used to retrieve altimeter data
do not provide reliable estimates of sea surface height in the nearshore region. Infrared derived SSTs provide high
50 | P a g e
resolution (< 4km), but are limited to cloud-free conditions. Microwave sensors provide all-weather SSTs, but the 25km
resolution limits their usability in coastal regions. However 40% of the world’s population resides in coastal areas, and
the increasing anthropogenic pressures on the coastal areas are making the ability to monitor these environments with
satellite data imperative. Presentations are sought that address the challenges associated with using satellite data in
coastal areas, along with those that apply remote sensing for research and/or applications.

processes are key controllers of coastal ocean water properties, including heat, freshwater, nutrients, and pollutants,
and they play significant roles in coastal ecosystem dynamics. This session will explore processes that drive exchange
across the continental shelf and slope in a variety of geographical settings including problems related to seasonal cycles
and inter-annual variability, extreme events, and linkages to ecosystem dynamics. Results from observational,
numerical, and theoretical efforts are welcome.

Session Title: The coastal carbon cycle: Understanding organic matter exchange and dynamics across terrestrial-marine
boundaries
Session Description: Transfer of carbon across the terrestrial-marine boundary and carbon cycling within estuarine and
coastal waters are important components of the global carbon cycle. The investigation of the complex interactions of
51 | P a g e
organic carbon in these environments requires multiple observational approaches for identifying material sources and
ages, exchange mechanisms, transport pathways, and process time scales. We invite contributions that examine the
dynamics of particulate and dissolved organic carbon in estuarine and coastal systems and how those processes mediate
the transfer of carbon from land to sea and between the water column and sedimentary environments.
Possible topics include: partitioning of organic matter between particulate and aqueous phases, exchange between
dissolved and particulate components, oxidation and burial in sediments, linkages between organic matter dynamics
and nutrient cycling, transport of organic matter, biomarker and isotopic studies, air/sea trace gas fluxes, carbon
sequestration and modeling approaches.

Session Title: Geological and Biogeochemical Dynamics in Major Deltaic Coasts
Session Description: River deltas occupy only 5% of the Earth’s surface, but nourish over a half billion people around the
world. Deltas play a vital role in transferring water, sediment and nutrients to the global coastal ocean. Many river
deltas, however, are endangered because of rising relative sea level and coastal erosion, leading to significant threats to
natural, economic and social systems. During the past half century, lots of deltas have been impacted by human
activities, such as levee construction, dam construction-induced sediment decline, as well as fertilizer-induced coastal
hypoxia. In this session we encourage the submissions of the studies on geological processes, biogeochemical processes
and the interaction of two in dynamic major deltaic systems through the use of field observations, numerical models, or
laboratory experiments. We propose to gather presentations that highlight recent findings on various aspects of deltaic
sciences, including coastal morphodynamics, sedimentary geology, sediment transport, coastal restoration,
biogeochemical cycles, as well as the linkages of water-column and seabed processes. Studies on the Mississippi and
Yangtze dispersal systems are particularly encouraged, and the studies in other deltaic systems are certainly welcome.

Session Title: Assessing the Health of Critical Freshwater, Estuarine, and Coastal Environments using Optical Remote
Sensing and in-situ Optics
Session Description: Freshwater resources and coastal and estuarine environments are being stressed by growing
human populations and their demands for resources. Changes in land use, loadings, and resource utilization are
significantly impacting these critical environments. The Group on Earth Observations (GEO) has identified water
resources as a key societal benefit area and seeks advances in Earth observation capabilities. Multispectral ocean color
sensors with moderate spatial and temporal resolution (e.g. MODIS and VIIRS) provide an excellent overview of the
coastal ocean. However, coastal and inland environments are typically diverse and dynamic ecosystems, requiring new
approaches for remote sensing. Presentations are solicited on recent advances in optical remote sensing to address the
complexity of coastal and inland waters. This includes results using in-situ bio-geo-optical characterization with field
spectrometers, airborne hyperspectral ocean color sensors (e.g. PRISM, AVIRIS-2) and new satellite sensors including
HICO, GOCI, and Landsat-8. Topics include methods to assess, monitor and predict the quality of coastal and inland
waters. Presentations on improved atmospheric correction and product algorithms, and new ways of exploiting
multispectral, hyperspectral and geostationary time-series data are solicited. Presentations on future sensors (e.g. OLCI,
EnMAP, and PACE), modeling and algorithms are also encouraged. This session will include oral and poster
presentations.

Session Title: Blue Carbon: Response and Mitigation Potential of Kelp, Seagrasses and Other Vegetated Habitats to
Coastal Climate Change and Acidification
Session Description: In this session, we will highlight observations of biogeochemical, ecological and physical
parameters associated with vegetated habitats (e.g., salt marshes, mangroves, seagrass beds, kelp forests, and algal
beds) in the context of climate change and ocean acidification. Predicting the response of marine ecosystems to climate
change, ocean acidification and hypoxia requires a better understanding of the natural variability of a variaty of
parameters in coastal and estuarine environments. This is particularly important for nearshore areas, where the carbon
system is more complex and variable than the open ocean. How will vegetated habitats respond to climate change and
do they present unique strategies (e.g., ‘blue carbon’) for coping with coastal biogeochemical change? Research focusing
on laboratory, theoretical and field experiments documenting the role, response and importance of photosynthetic
habitats are welcomed, as well as research focused on the sequestration of organic and inorganic carbon in these
habitats.

Session Title: Coastal Oceanography through Integrated Data Analysis
Session Description: With increasing coastal ocean observing systems collecting various data streams, our
understanding of continental shelf processes has advanced significantly in recent years. This session highlights new
scientific results obtained from these sustained or process-oriented coastal observations including, for example, moored
current meters, HF radars, AUVs, gliders, drifters, profilers, tide gauges, C-MAN stations, as well as satellites and other
remotely-sensed data. Progress on a variety of coastal topics such as along- and cross-shelf circulation and exchange,
upwelling and downwelling dynamics, sea level variations, tidal dynamics, buoyancy fluxes, local and remote forcing,
estuary-plume-shelf systems, offshore current/eddy intrusions, topographic influences, and their downstream impacts
are all encouraged. New insights from integrated data analyses covering multiple scales by combing two or more types
of data are particularly encouraged. Numerical model-assisted data analyses and accompanying insights are also
welcome.

Session Title: Progress in modeling seasonal to multi-decadal coastal change: A summary of the state of the art
Session Description: Reliable forecasts of coastal change that are capable of predicting evolution over time scales of
seasons to decades are in high-demand. Unfortunately, modeling the impacts of multiple storms, beach recovery
periods, seasonal variations, and climate variability are non-trivial, and certain processes are typically neglected. For
instance, most studies that attempt to assess the impacts of climate change on future coastal hazards neglect the
dynamic response of the coast due to the complexity of the processes involved. Therefore, these studies are missing a
key component of coastal vulnerability, as coastlines evolve continuously due to changes in wave conditions, sediment
supply, climate variability, sea level rise, and storm patterns. Due to the strong societal need for information on
projected coastal change at a variety of spatial and temporal scales, this topic is now attracting worldwide attention to
fill this knowledge gap. This session focuses on bringing together the state-of-the-science in seasonal to multi-decadal
coastal change modeling, including the latest advances for a variety of coastal settings, including sandy and rocky coasts,
lessons learned, and future challenges and research directions. This session will build on the success of an informal
workshop on this topic that took place during Fall AGU 2014.

Session Title: Carbon Fluxes in Coastal Environments: Research and Education
Session Description: Coastal ecosystems are highly productive, dynamic systems that provide critical ecosystem services
to human populations. Because these systems are increasingly threatened by a myriad of anthropogenic activities, it is
imperative that we develop that capacity to predict the impacts of present-day activities and the benefits of future
management strategies. Carbon fluxes across interfaces such as air-water, land-ocean, and sediment-water need to be
better understood, and their significance better communicated to the public, NGOs and government resource managers.
Resilience to ocean acidification, carbon sequestration potential, and amelioration of storm-induced sediment transport
are just a few examples highlighting the importance of current coastal carbon research. This session invites papers
exploring the measurement, modeling, or prediction of carbon fluxes in coastal areas as well as papers describing
education and outreach efforts regarding carbon cycling or carbon markets in coastal zones.

Session Title: Coastal Wetlands as an Important Interface Between Land, Sea and Atmosphere: Capturing Temporal and
Spatial Variability in Chemical Fluxes
Session Description: Coastal wetlands, including tidal marshes, mangroves, and seagrass beds, occur along much of the
world’s shoreline, with an area of ~500,000 km2. These ecosystems continue to experience rapid loss due to coastal
development, sea level rise, hydrological and sediment supply alterations, and other processes. In addition to their
ecological roles, coastal wetlands are a major sink for carbon dioxide and contain important carbon stocks in soils and
biomass. Under some circumstances they may be important sinks or sources for other greenhouse gases such as
methane and nitrous oxide. Lateral fluxes via tidal exchange between wetlands and adjacent estuaries and oceans may
also be important to wetland and connected water body chemical budgets. However the magnitude and processes
controlling exchange between coastal wetlands, the atmosphere and ocean remain uncertain, due to the large spatial
and temporal variability in these fluxes, and lack of a theoretical framework. This session will investigate exchange
across the interface between coastal wetlands, the atmosphere and the adjacent ocean. We welcome submissions on
chemical exchange, including greenhouse gases, carbon, alkalinity, and nutrients, across all spatial and temporal scales.
Presentations that highlight novel instrumentation approaches, high resolution time series, spatio-temporal variability,
isotopic sources, and modeling approaches are encouraged

Session Title: From coasts to the open ocean: global modeling of land –ocean fluxes and feedbacks on the continental
shelf
Session Description: The goal of this session is to provide a platform for coastal oceanographers and hydrogeologists
studying land-ocean interface for combining efforts in establishing the current state of our knowledge on magnitude and
effects of submarine groundwater discharge (SGD) on global scale. Despite the large amount of regional SGD data
collected in the last two decades, attempts of upscaling of SGD have been particularly difficult because of the large
temporal and spatial heterogeneity of fluxes. However, the translation from local scale to global scale is critical in
assessing the effects of land-ocean constituent fluxes and feedbacks in the ocean system. The lack of interactions
between the two scientific communities working at this interface, coastal oceanographers and hydrogeologists, had
contributed to a delay in this important matter. From terrestrial hydrology and geochemistry perspectives, modeling
continental scale SGD can advance our understanding and analytical capabilities relating to terrestrial hydrological and
biogeochemical cycles. To address this subject, the session invites contributions ranging from local field observations to
global model approaches of land-ocean matter fluxes. However, the contributors are encouraged to focus on the
upscaling of local observations to larger scales, or the downscaling of large scale information.

Session Title: Records of Carbon Burial and Biogeochemical Cycling in Coastal Wetlands: Response to Past, Present, and
Future Sea-Level Rise and Global Climate Change.
Session Description: Coastal wetlands, broadly defined as salt marshes, mangrove forests, and seagrass meadows, are
important transitional ecosystems that incorporate characteristics of both marine and terrestrial ecosystems. Along with
providing critical habitat for many economically important and protected species, they also provide critical ecosystem
services (including carbon sequestration and wave and storm-surge protection), thus having high economic value. These
highly productive ecosystems account for a disproportionately large amount of total organic carbon burial in marine
environments compared to their surface area and therefore play an important role in the global carbon cycle. Among
the myriad of global threats to coastal environments, accelerated sea-level rise is perhaps the greatest threat to coastal
wetlands. Sea-level rise and associated global climate change are expected to cause fundamental biogeochemical
changes in coastal wetland ecosystems that may provide a positive feedback on climate change, as once sequestered
organic carbon is oxidized and returned to the atmosphere. We invite submissions that focus on the relationship
between sea-level rise and biogeochemical function in coastal wetlands across multiple disciplines and spatio-temporal
scales, including modern process-based ecosystem function studies, paleo-records of biogeochemical and sedimentary
response to past sea-level rise, and projections of future trends and behavior.

Session Title: Advances in understanding biogeochemical processes in the coastal oceans: modeling, observations and
predictions
Session Description: Coastal ocean dynamics and related biogeochemical processes are complex, due to the influences
of coastal geometry, topography, hydrography, and atmospheric and deep ocean forcing, as well as variabilities and
interconnections of various biological and chemical components. In this session, we propose to discuss the latest
advances in interdisciplinary coastal ocean studies, modeling or observational, of the variability associated with: physical
processes including (but not limited to) ocean circulation, mixing and wave dynamics; primary productivity, algal blooms,
CDOM and other biogeochemical processes; coupled biological and physical interactions. Time scales for those
processes range from high-frequency (internal waves, storm events such as hurricanes and winter storms) to lower
frequency (long-lived ocean eddies, interannual to decadal variations in a changing climate). Research presentations

toward the quantification of predictability of those processes based on modeling or observational efforts are also
welcomed.

Session Title: Advances and Challenges in Ocean Operational Modeling and Product Services
Session Description: Real-time marine forecasting products based on numerical ocean models have being widely used
by a variety of applications ranging from guiding maritime transportation in ports, planning recreational activities for
general public and supporting hazard and emergency responses. Advances in observation technology, ocean dynamics,
numerical techniques and visualization tools have made the marine forecast more accurate and reliable and products
dissemination more timely and user friendly. However, the real-time applications of ocean modeling and product
services pose additional challenges such as real-time data acquisition and quality control, model stability, performance
assessment matrix, etc. This session will provide a forum for real-time applications of ocean forecasting based on
hydrodynamic, ecological modeling and/or the integrated land-air-ocean coupling modeling systems. Abstracts from the
following key areas are encouraged, such as (1) real-time maritime applications and products employing new
techniques; (2) tools and metrics for forecast performance; (3) advanced visualization tools for modeling products; (4)
issues and challenges in maintaining and improving the real-time systems; (5) pathway of transitioning research to
operations. This session will promote discussions on research requirements to meet the operational needs of real-time
ocean forecasting and product improvements.

Session Title: The Rise of Aquatic Hyperspectral Remote Sensing and Promised Advances in Coastal and Inland Water
Science and Application
Session Description: The land/sea interface plays a critical role in global biogeochemical cycles and in shaping and
sustaining marine and terrestrial ecosystems. These environments are highly complex, interconnected, and are vital to
human habitats and economy. They are rapidly changing with climate and increasing human activities. Remote sensing
is a critical tool for the study of inland and coastal waters and their watersheds and the advent of hyperspectral imaging
is expected to be transformational. New spaceborne hyperspectral missions will be launched shortly, such as EnMap
(Germany), PRISMA (Italy), and HISUI (Japan). The USA plans to launch specialized aquatic hyperspectral imagers PACE,
HyspIRI, GeoCAPE, and ACE. Meanwhile, numerous airborne sensors are being employed, such as AVIRIS, PRISM, and GLiHT. Algorithms are being developed to fully exploit the promised spectroscopic information to study coral reefs, sea
grasses, wetlands, and phytoplankton blooms. Recent advances herald new insight in areas of biodiversity, habitat
ecology, the status and fate of blue carbon, water resources and quality, harmful algal blooms, and human health and
safety. This session will explore the latest interdisciplinary research, and consider how this can guide future
development and utilization of hyperspectral remote sensing resources (in situ, airborne, and satellite) and better
inform public policy.

Session Title: New Insights in Coastal Oceanography from High-Frequency Radar Observations
Session Description: Over recent decades, high-frequency radar has become commonplace in observing surface
circulation in coastal waters. With hourly data and land-based operation that can be maintained continuously for years,
this technology provides new insights in coastal oceanography. At several sites, records of surface circulation have been
continued for over a decade, providing new information on interannual variability. Further, networks of radars provide
continuous coverage over hundreds of kilometers of coastline and up to 200km offshore. California invested significantly
60 | P a g e
in HF radar technology by establishing a statewide network 10 years ago. With the maturing of this technology,
attention has turned to what we can learn from HF radar data. These data have been assimilated in numerical models
and used in operational systems including search and rescue and oil-spill response. Studies along the California coastline
and around the world have produced new insights that could not have been generated without HF-radar observations.
The data have also been invaluable in education, enabling visualization of surface circulation in coastal waters. This
session seeks contributions that address transport patterns resolved by these data, including physical oceanographic
studies that explain flow patterns and biological/chemical oceanography studies that address transport in key ecological
and environmental questions.

Session Title: Morphological Evolution of Coastal Environments - Crossing the Land/Water Interface
Session Description: Models of sediment transport and geomorphic change in the coastal ocean have become more
detailed and probably more accurate. However, the oceanographic models are increasingly challenged in shallow water
and most of them stop at the water’s edge. Complete models of coastal environments must include subaerial processes
that shape the upper shoreface, dunes, bluffs, cliffs, and marsh and back-barrier environments, including aeolian
transport and effects of groundwater, permafrost, or vegetation. The goal of this session is to highlight research and
models that combine or couple both oceanographic and terrestrial processes to provide a more holistic representation
of coastal evolution.

Session Title: From watersheds to oceans – physical, ecological, and population models that cross boundaries
Session Description: Recently, there have been significant advances in research linking freshwater and coastal ocean
ecosystems. Much of this progress has been driven by the integration of empirical studies with physical and biological
models to elucidate the exchange of water, nutrients, and biological material between these systems. Examples include
biogeochemical modeling coupled with individual based models based on basic physiology, and life-cycles for fish or
other higher tropic level species. This session invites reports on interdisciplinary research projects and approaches to
further our understanding of how the exchange of water, nutrients, plants and animals between freshwater and marine
systems drives trophic, biogeochemical, population, and ecosystem dynamics. We encourage submissions that merge
novel modeling and experimental approaches and across a range of physical, spatial and temporal scales.

Session Title: The Dynamics of Buoyancy Driven Flows in Estuaries, River Plumes and on the Continental Shelf
Session Description: The mixing and dynamics of river water entering the ocean profoundly impacts ecological and
physical processes in the estuary and coastal ocean, representing processes at the interface between fresh and ocean
waters, and also at the interface between terrestrial and marine ecosystems. The dynamics of buoyancy driven flows are
complex due to the large range of scales and include stratified mixing, internal waves and frontal processes, among
others. These buoyancy--driven flows are influenced by many different factors, including freshwater discharge
magnitude, winds, surface gravity waves, tides and bathymetry. Understanding the complex dynamics of buoyancy
driven flows on the shelf is necessary for appropriate management of these valuable and sensitive coastal ecosystems.
We welcome submissions that investigate buoyancy driven flow in estuaries and over the continental shelf over a wide
spectrum of scales, including observational, numerical, theoretical, laboratory and remote sensing investigations.

Session Title: Coasts in Crisis: Sea Level Rise and Inundation and the Drivers for Adaptation
Session Description: Sea-level rise, a dominant driving force of coastal change, along with altered wave conditions,
storm intensity and ocean circulation patterns, is increasingly evident and important as a persistent and long term
hazard worldwide. The geologic record shows that sea level has been as much as ~8 m higher and ~130 m lower than
today within a timeframe that, though in a geological extent, coincides mostly with current coastal settings.. Sea-level
rise, with high regional variability, is accelerating and is expected to continue for centuries, with rise of 0.5 to 2 m
predicted by 2100. Inherent with this process is the expected increase in enhanced coastal storm and inundation activity
– further enhancing coastal flooding and damage. Adaptation planning is advisable with reliable and validated models
for predicting coastal change and inundation resulting from storms and rise. Papers invited include the impacts of sealevel rise, storms, waves on coasts; field and numerical model studies of storm surge, waves and inundation predictions
and effects; links between warming and sea-level rise; assessments of coastal impacts; examples of adaptation and/or
adaptive planning; national and regional investigations and/or policy of coastal elevation and change; and case studies.

Session Description: The global warming seriously influnce the variability of water mass and current system in East Asia
Marginal Seas（EAMS) and EAMS is one of the fastest warming area in the global ocean. Recent observations and
modeling studies have suggested links among the variations of the EAMS ，the global climate variability and Pacific
western boundary current. The frequently burst of ecological disaster in EAMS was confirmed to influnce by the
hydrological variation of EAMS. The session will focus on the multi-scale hydrodynamic process in EAMS and its influnce
to the continental shelf ecosystem. In this session, researches on the hydrodynamic variation of EAMS, impact of
kuroshio and East Asia Monsoon to the EAMS，the design of observation system and numerical forecasting system on
EAMS is welcomed. In addition, contributions are also encouraged about the impact of hydrological variation of EAMS
on the variability of ecosystem in EAMS.

Session Title: Autonomous systems for study of coastal and estuarine processes
Session Description: This session is intended to review the current state-of-the-art in the use of autonomous systems for
observation and study of coastal and estuarine processes. Autonomous in this context refers to all forms of unpiloted
systems operating in the air, land, and sea and focused on coastal zone sensing including unmanned aircraft systems
(UAS), autonomous underwater vehicles (AUVs), gliders, and potentially autonomous terrestrial vehicles. This session
will consider technology development, methods for data acquisition, and how data from these systems are processed
and applied to measure and analyze coastal and estuarine processes. The geographic domains of interest extend from
the littoral boundary inland through sub-aerial coastal landforms to estuaries. Of particular interest in this session is the
use of UAS for coastal mapping, hazards assessment, and monitoring nearshore processes; integration of data acquired
from unmanned systems for model calibration or parameter estimation; fusion of measurements derived from air and
sea platforms; and all other emergent forms of the use of autonomous systems for study of coastal and estuarine
processes.

Session Title: Shelf-slope exchange: coupling of physical, biogeochemical and biological processes at the interface of the
continental shelf and deep ocean.
Session Description: Exchange at the interface of continental shelves and the open ocean is a critical link between
regional and global scale ocean processes. Regional and local-scale differences in shelf-slope exchange can be related to
a range of factors, including air-sea interactions, the formation and persistence of fronts, the proximity of strong
boundary currents, tidal forcing, shelf/slope configuration and the complexity of local bathymetry. In this session we
invite contributions that emphasize inter-disciplinary approaches to the study of shelf-slope exchange processes.
Contributions are encouraged from observational and modeling studies that address the coupling of physical,
biogeochemical and biological processes in the outer shelf to upper slope region in various systems as well as
submissions that illustrate similarities and differences in shelf-slope exchange across shelf margin settings, seasonal and
inter-annual patterns, and the role of episodic or extreme events.

Session Title: Dynamics of the Arctic Ocean and Sea Ice System in a Changing Climate
Session Description: Major sea ice loss and Arctic air temperatures rising faster than the global mean are precursors of
significant change that the Arctic Ocean is already beginning to experience. The retreat of sea ice greatly affects the
Arctic system, allowing the direct exchange of heat, momentum and fresh water between ocean and atmosphere with
implications for the ecosystem as well. Recently, novel and innovative year-round observational programs provide
insight on this transition, however a correct interpretation of the changes inevitably requires an improved
understanding of the actual processes at play. In the context of a changing Arctic, this session invites observational and
modeling studies describing and quantifying dynamical processes, feedbacks and the role of fluxes across the air-iceocean interface. Particular attention will be paid to topics such as momentum transfer into the ocean, the transfer of
energy across scales, connections between the surface and the deep ocean (e.g. internal waves and mixing), and links to
changes in stratification and large-scale circulation. Submissions on both physical and multi-disciplinary aspects are
welcome.

Session Title: Waves, Ice, and Winds across the Changing Arctic Ocean
Session Description: With recent declines in the extent of seasonal ice cover, air-sea-ice interactions in the Arctic are
changing. This session focuses on Arctic surface processes, with a particular emphasis on the hypothesis of increasing
wave energy and therefore the increasing importance of wave-ice interactions. Wave-ice interactions include wave
attenuation and scattering, as well as feedbacks to the ice, including the fracturing of continuous ice, the controls on
floe size distribution via fracturing, and impacts on ice characteristics during formation (e.g. pancake ice). These
processes may dominate in the marginal ice zone (MIZ) and modulate the exchange of heat between the ocean and
atmosphere. This session is intended to include results from in situ observations, remote sensing, laboratory
experiments, and numerical models. Climatology studies of Arctic surface influences are also welcome.

Session Title: What Regulates the Seasonality in Southern Ocean Productivity?
Session Description: Southern Ocean primary productivity plays an important role in regulating marine resources, ocean
biogeochemistry and the global carbon cycle. Canonically, variations in iron supply and demand are thought to central
to the control of phytoplankton productivity. However, via the actions of ocean physics, the Southern Ocean also
encounters substantial fluctuations in temperature, and the availability of light and/or macro- and micro-nutrients over
different timescales. How these regulatory factors act individually and in combination to shape the dynamics of
biological activity across food webs in different Southern Ocean regions is not well understood. This hampers our ability
to project with confidence how future environmental change will affect this important ecosystem. Thanks to
GEOTRACES we have an emerging picture of the distributions and surface supply of iron in this region, but how this is
underpinned and connected to the broader picture of ecosystem structure and biogeochemical feedbacks, over
different spatial and temporal scales, is lacking. We invite presentations from field, laboratory, remote sensing and
modelling studies that seek to unravel the seasonal dynamics of upper ocean productivity from different regions of the
Southern Ocean. Efforts to combine insights across disciplines from physics to biogeochemistry to ecosystems are
actively encouraged

Session Title: Heat transport processes in the Arctic Ocean's Atlantic and Pacific water layers
Session Description: One of the most significant contemporary changes to occur in the Arctic Ocean has been a warming
of the Atlantic and Pacific water layers. This warming impacts sea-ice cover only where the ocean heat is transported to
the surface. However, over much of the Arctic Ocean the strong halocline stratification insulates the surface ocean and
sea-ice cover from the underlying Atlantic and Pacific waters. Therefore, in order to predict and model Arctic sea-ice it is
crucial to understand processes that are able to flux this heat vertically to the ocean surface. A whole host of processes
are expected to play a role in this transport, such as double-diffusive convection, lateral intrusions, wind and internal
wave driven mixing, as well as coastal upwelling and mesoscale eddies. This session invites submissions that investigate
the vertical and lateral transport of heat from the Atlantic and Pacific layers. We invite studies that focus on the range of
important heat transport processes, and encourage studies that encompass observational, theoretical and numerical
approaches, to understand ocean heat transport in a changing Arctic system.

Session Title: Predicting changes in the Arctic Sea Ice cover using coupled atmosphere-ice-ocean-wave modelling
systems.
Session Description: This session will address Arctic sea ice prediction with an emphasis on coupled modeling systems
(e.g., ocean-ice, atmosphere-ocean-ice, atmosphere-ocean-ice-wave). The heat and freshwater storage in the upper
ocean plays a large role in the melt and re-freeze of the ice in the Seasonal Ice Zone. What are the impacts of ocean-ice
feedbacks and the role of ocean initialization (with and without waves) on sea ice prediction? How should snow cover be
represented in ice modeling systems? What are the methods to quantify and assess model skill (forecast verification) in
coupled modeling systems? What is the present status of sea ice prediction on multi-day to seasonal and annual lead
times? Also of interest are developments in sea ice modeling relevant for high-resolution simulations, such as improved
rheologies and form drag parameterizations.

Session Title: Dynamics on the edge: shelf-sea and continental slope processes of the Arctic and subpolar Arctic
Session Description: It is now beyond dispute that the Arctic is experiencing rapid climate change. There remain many
open questions about the future of the Arctic and how changes occurring here will impact the lower latitudes. In the
Arctic and subpolar Arctic, freshwater inputs from rivers and glaciers are dispersed across the shelves where vigorous
mixing from winter convection, winds and tidal dissipation transform water masses. The mechanisms controlling export
from the shelves and other cross-slope exchange processes including eddy fluxes and Arctic Ocean lateral intrusions
carrying Atlantic heat, salt and biogeochemical tracers into the central Arctic basins are likely to be sensitive to changing
ice and freshwater conditions but remain unresolved. Boundary current dynamics interacting with separate first-order
shelf-slope exchange processes set the stratification in the Arctic and the sub-polar Arctic seas i.e. Greenland, Irminger,
Norwegian, Labrador and Bering, and are likely to ultimately impact deep convection and meridional overturning. We
invite physical and biogeochemial contributions from colleagues focusing on shelf and slope processes, especially shelfslope exchange, boundary current dynamics, freshwater dispersion and communication between the high Arctic and
subpolar Arctic seas.

macroecological approaches in polar regions that range from the micron scale (e.g., flow cytometry; phytoplankton, ice
algae and bacteria) to the km scale (e.g., satellite pixels-from-space; spring and fall blooms). We encourage
presentations at melt ponds, arctic lakes and ocean basin spatial scales and turbulent bursting phenomena to longer
time scales as well as research on complex systems and thresholds. We especially invite advances linking the hard-tomeasure biological distributions to the easier-to-measure physical conditions at large and long temporal scales.

Session Title: Fjord dynamics and interactions with land, ice, and the continental shelf
Session Description: Fjord systems play a fundamental role in the transport of heat, salt, sediment, and other material in
high latitude systems. They are a key interface between the land and open ocean, and in many regions they provide an
outlet for the discharge of ice from rapidly retreating glacier systems. This session focuses on theory, observation, and
modeling of fjord processes, including: the relative role of ocean forcing versus internal fjord dynamics in determining
the circulation, the dynamics of riverine- and glacier-forced freshwater plumes, sediment discharge from land and its
accumulation in the ocean, and the mechanisms of deep water renewal.

Session Title: Climate change induced changes of the sea ice interface and its implications on biogeochemical cycles
Session Description: The Arctic is one of the regions where the effect of climate change is most pronounced and
currently significant transformations occur. The most striking physical changes are associated with diminishing sea ice
70 | P a g e
extent and thickness, resulting in a loss of an important interface between the ocean and the atmosphere.
Understanding the response of biogeochemical cycles and the Arctic marine ecosystems to these changes requires the
integration of physical, biological and chemical oceanographic studies across a range of temporal and spatial scales. In
addition climate change increased the warming polar waters at the fastest rate on the planet, with a transition of the
key species from large to small cells highlighting the critical role of small cells in carbon cycling. Integrating modelling
and observations will identify linkages and feedbacks between atmosphere-ice-ocean forcing and biological-geochemical
processes and will subsequently improve the prediction of future scenarios. Here, we seek interdisciplinary data and
synthesis products that elucidate the current status of the physical and biogeochemical processes in the Arctic marine
system on regional and global scales, how feedbacks and controls could change these systems and ultimately, what new
conditions might be present in the Arctic on decadal and longer time scales.

Session Title: The Physics, Biology and Biogeochemistry of Marginal Ice Zones
Session Description: Rapid decline in Arctic summertime sea ice extent has produced extensive seasonal ice zones,
where broad marginal ice zones separate pack ice from open water. The potential importance of these transition regions
motivates efforts to understand the processes that control evolution of the marginal ice zone and the potential changes
that may accompany increased seasonality. The complex interplay between ice, ocean and atmospheric processes, and
the potentially strong feedbacks between, modulate sea ice melt and the transfer of momentum and buoyancy into the
upper ocean. For example the influence of wind, waves and passing storms drives highly variable floe size distributions,
which impact melt rate, momentum and heat transfer, light fields and phytoplankton productivity. Similarly, increased
areas of open water may lead to stronger coupling between atmosphere and ocean, internal wave generation and
elevated upper ocean mixing. This session invites presentations that describe observational, experimental, theoretical
and numerical investigations of MIZ processes in both the Arctic and Antarctic.

Session Title: Sea ice biogeochemistry and ecology: observation, patterns, and changes at the interfaces of ice and
ocean
Session Description: Sea ice covers 25 million square kilometers of the Earth and plays an important role in regulating
global climate. In recent years, the extent and volume of sea ice in the Arctic has declined, while Antarctic sea ice
coverage is slowly increasing. Although these regions are separated in space and time, with different physicochemical
properties, the changes in their sea ice ecosystems could provide complementary insights as to how sea ice impacts
biological productivity, nutrient cycling, and trophic interactions. The session invites contributions from a variety of
studies on sea ice ecosystems ranging from carbon and nutrient cycling to cryo-pelagic-benthic coupling. The session
also welcomes contributions on the role of sea ice to biodiversity, key polar species, and ecological functioning.
Multidisciplinary studies linked with sea ice physics are of particular interest. Together, contributions will provide the
community with a broad view of research within sea ice and at the interfaces of sea ice and the ocean from both Arctic
and Antarctic realms.

Session Title: The Beaufort Sea in Transition: Responses to Climate Change and Human Impacts
Session Description: The Beaufort Sea comprises a seasonally ice-covered and comparatively shallow shelf characterized
by the strong influence of productive waters from the Chukchi Sea in the west and high riverine inputs along the entire
shelf, peaking in the east with the Mackenzie River. Over a steep slope, shelf waters interact with the complex
hydrography of the deep Canada Basin. This interface between the coast of North America and the open Arctic Ocean is
experiencing sea ice retreat, increased coastal erosion, enhanced primary productivity and upwelling, and oil and gas
exploration. We welcome scientists from all disciplines of the ocean-science community to submit abstracts for this
session to help advance our knowledge of the status and processes that define this critical interface and its response to
climate change and human impacts. We are especially interested in abstracts that link aspects of circulation, primary
productivity, nutrient and carbon chemistry, arctic contaminants and/or the structure and function of biological
communities to environmental forcing factors.

Session Title: Western Antarctic Seas: From Trace Metals to Trophic Levels
Session Description: Western Antarctic Seas are some of the most productive on earth. Therefore, it is no surprise that
they have been the focus of numerous studies over the past several decades highlighting the importance of this region
to the Southern Ocean and global elemental cycles. Western Antarctic Seas support a highly productive and diverse
marine ecosystem that is strongly driven by seasonal shifts in micronutrient and light availability. Although mostly
isolated from many of the direct anthropogenic influences in temperate regions, these seas remain highly susceptible to
seasonal and climatic environmental change. This session invites research that is focused on changes occurring in the
Western Antarctic due to disruptive singular events or changes over seasonal, annual or decadal (climate change) time
scales. We encourage a variety of research topics including observational and manipulative studies spanning from trace
metals to trophic levels. Abstracts may encompass the response of organisms to change at the physiological level and
impacts of change on the structure and function of the Western Antarctic ecosystem.

Session Title: An integrated approach to recent change in the Antarctic coastal ocean
Session Description: Over the last several decades the Southern Ocean has been experiencing a wide range of change,
including: absorption of anthropogenic CO2 and consequent changes in pH, changes in wind stress and upwelling, with
impacts on nutrients and primary production, changes in patterns of annual sea ice distribution, increasing contribution
of meltwater to the coastal ocean, and the introduction of invasive species. Biological responses to these complex and
often inter-related changes are observed with impacts cascading through all levels of the Southern Ocean marine
ecosystem. This session invites contributions from diverse research programs, including those addressing recent change,
via modern process studies, systematic and repeated sampling efforts, and modeling, as well as from a
paleoceanographic perspective, with marine sediment and ice cores records from the past several centuries providing a
longer time scale frame of reference.

Session Title: Physical and Ecological Impacts of Land Reclamation on Coastal Waters
Session Description: Although restoration of coastal wetlands is widespread in developed countries, economic and
population pressures have constrained similar large-scale reclamation activities on coasts and islands of many
developing countries. Thousands of kilometers of shorelines have been permanently modified through construction of
dikes, seawalls, groins, and other engineering structures. Many areas that served as critical habitats for migrating birds
and as hatcheries and nurseries for aquatic organisms have been lost because tidal marshes, mangroves, dunes, coral
reefs, and shellfish beds have been transformed for agricultural, urban, and industrial uses. The morphologies of river
deltas and estuaries have been altered due to changes in tidal dynamics, wind-wave interactions, natural circulation, and
transport of sediment and solutes. The direct and indirect impacts of coastal land use changes on coastal circulation,
sedimentation, water quality, and ecological health have not been adequately investigated. The purpose of this session
is to bring together international researchers involved in study of environmental impacts of coastal reclamation. We are
particularly interested in regional studies that demonstrate impacts of coastal modifications on the physics and ecology
of estuaries and coastal waters. It is hoped that the presentations will provide scientific guidance and suggest innovative
solutions to problems of coastal land reclamation.

Session Title: The impact of seawater desalination on the marine environment
Session Description: Freshwater is a rare commodity. More than a third of the world’s population lives in areas with
water shortages that are vulnerable to drought. The increasing need for potable water, in conjunction with technological
advances, has transformed large scale seawater desalination into a fast-growing industry worldwide. In contrast to the
75 | P a g e
rapid technological development, the long-term environmental impacts of desalination on the marine ecosystem have
been poorly documented. Among the possible effects are entrainment and impingement of organisms at the intake,
changes in the physico-chemical environment at the brine outfall (including chemicals used in the desalination process),
and shifts in the biological communities. The scant published studies emphasize the effects of salinity on the benthic
communities and those are site- and organism specific and provide conflicting results.
We invite abstracts that explore the impacts of seawater desalination on the physical, chemical, biological, and
ecological aspects of the marine environment. We welcome a range of presentations covering in situfield
measurements, controlled laboratory studies and modelling of seawater intake and brine discharge. Of special interest
are studies integrating the different methodologies into a holistic view, an approach that is lacking in the literature, and
is essential for future planning and regulation.

Session Title: Marine Renewable Energy: Resource Characterization, Environmental Impacts, and Societal Interactions
Session Description: To reduce greenhouse gas emissions, there is an urgent need to support our electricity generating
capacity through the development of low carbon technologies, particularly those generated from renewable sources.
The ocean represents a vast and largely untapped energy resource, that could be exploited as a form of low carbon
electricity generation, and there is much research within the oceanographic community into resource characterization
and environmental impacts. This session seeks contributions spanning a broad range of topics related to marine
renewable energy, including wave, ocean current and tidal resource assessment (and wave-tide interactions) over
timescales ranging from semi-diurnal to decadal, and feedbacks between electricity generation and the resource at both
device and array scale. The session will also include studies of environmental impacts of arrays of marine renewable
energy devices, covering physical impacts (e.g. impacts on sediment dynamics affecting beaches and offshore sand
banks), and ecological & societal interactions of marine energy devices. We welcome contributions which examine
either theoretical studies or case studies, and which include either observational or modeling methodologies.

Session Title: Offshore Energy I: Connectivity and Habitat Consequences of Rigs-to-Reefs Programs
Session Description: Worldwide, thousands of offshore oil and gas platforms will soon cease energy production. Instead
of complete removal, rigs-to-reefs (RTR) programs that permit at least a portion of decommissioned platforms to remain
in the ocean are now being considered by a number of different countries. Understanding the potential environmental
effects of novel habitat created by offshore oil and gas platforms is an important information need for managers when
considering RTR proposals. This situation presents a timely opportunity for marine science to inform policy decisions at
an international level. As de facto artificial reefs, platforms may change species composition and abundance or biological
productivity of an area. When interacting with flow fields and the distribution of natural reefs, these structures may
alter population connectivity at local or regional scales. This session will provide a forum to (1) describe tools for
measuring artificial reef performance (e.g. comparative demographic rates with natural reefs) or analyzing connectivity
(e.g. ocean modeling of propagule dispersal, genetic analyses, tagging studies), (2) elucidate potential outcomes from
either altered connectivity (e.g. facilitate non-native species colonization) or from the creation of an artificial reef
complex (e.g. affect fishing effort), and (3) identify data gaps in any of these areas.

Session Title: Marine Debris Monitoring and Assessment: The Science Behind Prevention
Session Description: Anthropogenic marine debris has been found in coastal and ocean ecosystems across the globe,
and is emerging as a major threat to marine species and habitats. Assessment of the quantity, composition, and spatial
extent of marine debris is necessary to understand the drivers of debris accumulation and impacts on wildlife and
habitats. Monitoring projects are essential to evaluate the success of efforts to mitigate marine debris, and can be used
to develop more effective prevention programs and policies to reduce impacts on coastal and marine ecosystems and
communities. At present, a myriad of approaches to marine debris monitoring are being implemented on local, regional,
77 | P a g e
and national scales, through both traditional research and citizen science programs. This session will examine results of
marine debris monitoring and assessment efforts, data management and analysis approaches, new technologies, and
compatibility among field techniques and data collection tools. Discussion will consider how these efforts may be used
to inform priorities and approaches for preventative actions, evaluate effectiveness of mitigation measures, better
understand debris sources and life cycles, and assess the chemical, biological, physical, and/or socioeconomic impacts of
marine debris.

Session Title: Offshore Energy II: Exploring Effects from Renewable Energy
Session Description: Offshore marine renewable energy (wind and wave energy conversion to electricity) seeks to prove
itself as a viable industry on the outer continental shelf of the United States (U.S). Agencies, industry, and scientists
involved in U.S. efforts to develop the processes are supporting and conducting research off the Atlantic and Pacific
coasts and Hawaii. Efforts in the U.S. have the opportunity to benefit from investigations across European seas, where
offshore renewable energy from wind and wave is well established. This session is designed to gather and relate
research methods, plans, and results from global investigations into field techniques, statistical modeling, and
integrative mapping used to assess the presence, distribution, migration, dispersal, and/or abundance of species most
likely affected by offshore renewable energy at local and regional scales. The potentially affected species, such as
seabirds, marine mammals, fish, sea turtles, and decapod crustacea, may traverse multiple environments. We also invite
reports of research into the potential or existing effects due to novel aspects of offshore renewable energy structures,
such as the presence of artificial habitat, noise, electromagnetic field emission, and species barrier or displacement, and
before and after studies of specific sites and projects in the marine environment.

Session Title: Continuing Perspectives on Restoration in the Gulf of Mexico: From Coastal Habitats to the Deep Sea
Session Description: Almost six years has passed since the explosion of theDeepwater Horizon oil rig in the Gulf of
Mexico (GoM) resulted in the largest accidental marine oil spill in history, and we continue to see impacts to the diverse
habitats that thrive in this region. In order to combat continued degradation, improve ecosystem health, and stimulate
recovery, major efforts identifying productive restoration strategies are underway. The science of restoration in the
GoM is a complex, multidisciplinary endeavor, requiring differing strategies depending on the habitat of concern, as no
single strategy can be applied across all impacted environments. Restoration may involve direct reconstruction of
certain habitats while other habitats may require protection from future disturbances. Given that theDeepwater Horizon
oil spill was implicated in detrimental impacts to a wide variety of GoM habitats, and that the extent of these impacts
are still being realized, the time is right to revisit and identify the relevant research required for developing effective
restoration plans. Contributions from NGOs, government and academic researchers, and resource managers that discuss
the various difficulties and challenges associated with developing restoration strategies, designing marine protected
areas, and monitoring restoration success in the nearshore, offshore, and deep-sea will be welcomed.

Session Title: Ocean-Atmosphere System Geoengineering: Benefits and Detriments
Session Description: Large-scale geoengineering approaches may produce substantial societal benefits. However, to
date it is unclear if potential benefits would outweigh possible negative impacts on the environment. Therefore, a
cautious approach to geoengineering must be taken because altering the ocean-atmosphere system may have
unexpected consequences. The potential to help society mitigate climate change versus the inherent risks of negative
impacts require adequate research. The US National Academy of Sciences has recently concluded “…that with proper
governance, which it said needed to be developed, and other safeguards, such experiments should pose no significant
risk.” This session, in addition to “traditional” geoengineering options, including capturing and storing some carbon
dioxide and reflecting more sunlight to outer space, will consider the options relating to the ocean and air-sea interface.
Further topics include but are not limited to: • Advances in the methodology of artificial upwelling with potential
applications in marine aquaculture and fisheries;
• Ocean iron fertilization for CO2 sequestration;
• Cooling the ocean for hurricane mitigation and climate modification.

The latter is an interesting but more questionable approach, which however could become more effective in
combination with solar radiation management and CO2sequestration.

Session Title: The Science of Marine Debris: Here, There and Everywhere
Session Description: Marine debris, marine litter, microplastics, microbeads, abandoned and derelict vessels, and Japan
tsunami debris are all topics that have received increasing public attention over the past few years. Marine debris is a
global issue that affects marine organisms from the smallest creatures to the largest whales via ingestion, entanglement,
and habitat impairment. It has been found in rivers, lakes, and the ocean from the equator to the poles, including deep
sea sediments and ice cores. Marine debris also affects humans who live in coastal communities and depend on the
ocean as a way of life. This session will provide a learning environment for those who are 1) new to the science of
marine debris, or 2) interested in the wide array of marine debris issues. Presentations may focus on the movement of
marine debris, sources and sinks, and impacts to marine wildlife and habitats. Presentations that would fit into this
session include:
Marine debris hot-spots – debris movement, convergence zones, and collector beaches
The emerging science of microplastics
Wildlife and habitat impacts, including invasive species
Derelict Fishing Gear (DFG) and Abandoned and Derelict Vessel impacts – studies and solutions

Session Title: Coastal Geomorphology, Subsistence Resources, and Community Resilience
Session Description: Climatic, tectonic, and human-related impacts are changing the distribution of both shorelineassociated food resources and habitats critical to fishery food webs. Shorelines are vulnerable to change due to isostatic
rebound (ground rebound following glacier retreat), tectonic shift, sea level rise, exposure, substrate type, oil spill
residence, and native and non-native species invasion. There is a need to summarize current and future shoreline
geomorphic – biotic relationships to better understand potential impacts to subsistence resources and lifeways. Such
interdisciplinary synthesis studies provide critical background information for state and federal managers having the
objective of sustaining Native life ways. By strategically integrating Native knowledge, inclusive vulnerability assessment
strategies are created facilitating win-win research opportunities for resource users and research scientists alike. In this
session, we welcome interdisciplinary studies integrating components of science with Native knowledge; studies aimed
to better understand underpinnings of community coastal resilience.

Session Title: Research findings and challenges in oil spill organic geochemistry studies
Session Description: Since the 2010 Deepwater Horizon (DwH) oil spill, more than 40 oil spills have occurred throughout
the world, releasing 39,000 - 260,000 tons of crude oil. Most spills occurred on the surface but deepwater spills, such as
DwH, are also important research topics. Besides, the importance of released petroleum from marine natural seeps is
increasingly recognized. Researchers around the world from academics, government, and industry have conducted
remarkable studies to better understand various oil weathering processes and spatial distribution of residual oil in soils,
sediments and marshland. The proposed session will provide an opportunity to present novel organic geochemical
approaches, report current research findings, and promote ideas for collaboration with other research areas.
Contributions dealing with subjects such as, but not limited to, the fate of hydrocarbons in the ocean and on coastlines
(e.g., incorporating in the food web and accumulating in sediments), oil degradation processes (e.g., biodegradation,
photodegradation, and formation of oxygenated weathering products), differences between spilled and seeped oil, and
the application of novel analytical methods are encouraged. Both oral and poster presentations will be accepted.

Session Title: Advancing Water Quality Monitoring and Forecasting in Urban Coastal and Inland Waters
Session Description: Water is an increasingly threatened resource, particularly the quality of coastal and inland waters
due to population growth, urbanization and climate change. Further, the interfacial nature of the urban coastal zone,
bridging aquatic, terrestrial, atmospheric and anthropogenic domains, means they are significantly impacted by dynamic
and complex processes. Timely, accurate, and consistent scientific-based assessments, monitoring and forecasting of
water quality are crucial across global, regional and local scales. This session solicits contributions addressing the endto-end value chain for urban coastal and inland water quality. This includes new and improved physical,
biogeochemical, and ecological observations and data (remote and in situ), model output with data assimilation and
forecasts, and synergistic generation of fit for purpose water quality products and indicators to provide integrated
information for water quality managers and other stakeholders. In particular, developmental and operational activities
that couple products and indicators (from observations, models etc.) across the land-water interface are solicited, as are
information delivery systems and decision making tools to enhance user knowledge. This session advances goals and
objectives of the international Water Quality Summit held in 2015 by the Group for Earth Observations, particularly
development of urban water quality monitoring and forecasting service(s) in developed and developing nations.

Session Title: Co-design, co-production, co-communication of scientific knowledge– how to frame concerted research
for sustainable development in times of change
Session Description: This session addresses questions of how scientific knowledge is co-designed, co-produced,
communicated, received, perceived and utilized by local communities in coastal areas. The aim is to focus on the
relationships between producers and users of scientific knowledge and what policy measures may be needed for
improvement.
The world ocean is undergoing rapid changes, which impacts local communities, countries and larger regions in different
ways. These changes are forcing critical decisions regarding preparing for climate impacts like sea level change, ocean
acidification and warming, as well as human activities like fishing, shipping, oil and gas extraction, tourism and others.
Only a holistic approach, encompassing ecological, economic and social considerations will allow societal transformation
for sustainable development in times of change. This obviously needs the involvement of multiple perspectives,
disciplines, and sectors within science, society, industry and policy.
The session encompass examples of
1) Knowledge generation, including development of scenarios and narratives and perception frameworks
2) Co-design and co-production of research, including approaches like citizen scientists (crowd science)
3) Ways of communicating between science and stakeholders, including effective feedback mechanisms and innovative
ways of communication
The specific role of indigenous communities as producers and consumers of knowledge.

Session Title: In-situ Sensors and Instrumentation for Improving Understanding of Ocean Processes and Ecosystems
Session Description: The earth’s oceans cover over 125 million square miles of its surface, are heterogeneous at both
local and regional scales, and are known already to be responding to the changing climate. It is widely recognized that
in-situ measurement methodologies are critical for characterization of marine processes (physical, chemical, biological)
at the spatial and temporal resolutions necessary to understand the complex ecosystem interconnections and to predict
the reaction of these systems to new forcings. This session focuses on the development and demonstration of novel
sensors and instruments for in-situ use, with a particular focus on engineering innovations and challenges, within the
context of pressing oceanographic questions. Topics may include: (1) adaptation of traditional instrumentation for field
use, i.e., “field hardening,” (2) development of novel in-situ hardware (new techniques or new targets), or (3) innovation
drastically improving functionality of existing designs such as methods for reducing energy consumption, continual
calibration, data storage/transmission, bio-fouling limitation, etc.

Session Title: Advancing Ocean Biogeochemistry with In Situ Sensing Technologies
Session Description: Development and deployment of in-situ sensor technologies for measurements of biogeochemical
parameters have been widely recognized as a research priority in the oceanographic community. This stems from the
need to study dynamics of ocean biogeochemistry on various temporal and spatial scales ranging from
seconds/millimeters to decades/thousands of kilometers. Recent advancements in both biogeochemical sensing
technologies and their fast-growing applications have prompted oceanographers to tackle complex issues and questions
that otherwise are difficult to address adequately. Biogeochemical in-situ sensors have been widely used in diverse
marine environments on various observational platforms with many successes as well as unforeseen challenges. It is
critical to communicate both cases to the ocean biogeochemistry community with the goal of improving ocean science
studies based on in situ sensing technologies. This interdisciplinary session welcomes contributions from a broad
spectrum of ocean researchers to present the latest developments in sensing technologies, data quality control,
applications of high-resolution sensor data to address challenging research questions as well as to identify the broader
issues and solutions of development and operation, study design, and publication or dissemination of the data. The aim
of the session is to bridge technology development with real world applications in order to advance ocean
biogeochemistry.

Session Title: Airborne Systems in Support of Oceanographic Research
85 | P a g e
Session Description: This session will review current and future methods and uses of manned and unmanned aircraft in
ocean sciences, including ocean-atmosphere interaction studies, remote sensing, satellite product validation, marine
mammal and seabird populations, oceanographic mesoscale and submesoscale processes, as well as studies of sea ice,
fisheries and shipping. This topic is timely because of advances in sensor capabilities, and the increasing availability of
airborne systems to the scientific community, likely to expand with the recent Federal Aviation Administration (FAA)
approval of unmanned aircraft research centers in the US. FAA regulations have been drafted to facilitate Unmanned
Aircraft Systems (UAS) operation >12 miles offshore. Together with recent changes in FAA small UAS regulations, the
increased availability of UAS systems provides increased opportunities for use by the oceanographic community. This
session will also address UAS integration in the research fleet. Operation of UAS from shore and ships can advance
oceanographic research and expand capabilities of ocean observing systems. Additionally, use of airborne systems in
coastal and offshore waters provides information for marine resource management and response to natural and
shipping accidents, including search and rescue, coastal erosion, and oil spill response. Examples of airborne operations
in support of oceanographic research will be highlighted.

Session Title: Advances in Lidar for the Detection of Layers and Physical Processes in Aquatic Environments
Session Description: Light penetration into water is dependent on the source wavelength and the concentration and
distribution of dissolved and particulate material in the aquatic environment. Profiling lidars have the ability to probe
the sub-surface structure of water and detect bio-optical layers and sub-surface processes. These optical layers vary
from less than 20 cm to much higher and are associated with biological (phytoplankton and zooplankton) to detrital
particle layers that respond to physical processes such as the mixed layer depth, internal waves and turbulence. This
session aims to explore standard and emerging submersible, surface, air and space lidar technology including elastic
space lidars, high spectral resolution lidars and tunable systems. In addition, we aim to discuss the importance of
polarized returns and advances in blue laser technology. We welcome all contributions that focus on the development
and use of profiling active systems to further our understanding of optical properties in riverine, coastal and open ocean
environments in order to demonstrate the potential and limitations of these systems in various water types.

Session Title: Recent Advances for In Situ Biogeochemical Instrumentation, Sensors, and Observatory Science
Session Description: Complex interactions affecting aquatic biogeochemical cycling occur over a wide range of spatial
and temporal scales. Detailed observations of one set of physical, biological, or chemical indicators often serve as signals
for initiating complementary sampling strategies to better understand the world around us and inform management and
policy decisions. While meteorology has long benefited from widespread observatory infrastructure, aquatic sciences
have only recently begun to break through technological and practical barriers for deploying more diverse instruments
in the environment to address limitations of classic ‘undersampled’ systems and ‘snapshots’ in time. It is thereby
necessary to advance technologies that improve our ability to continuously quantify biogeochemical parameters with
high spatial and/or temporal resolution.
Recent advances and decreasing costs in embeded systems, nanotechnology, open-source hardware and software, and
telecommunication enable the launch of monitoring systems and networked observatories. This session will invite a
broad group of aquatic researchers and engineering-minded scientists to share updates on recent advances in sensor
development, new instruments, hardware, or software technologies to enable previously unavailable widespread
deployment of lower-cost ‘mininodes’ in aquatic environments including hydrothermal systems, water columns, coastal
systems, and sediments.
This session would be an ideal candidate to include hardware or software tutorials.

Session Title: Advancing Discovery, Observation, and Process Studies Throughout the Ocean with Robotic Technologies
Session Description: Understanding ocean processes requires observations over a broad range of temporal and spatial
scales, and motivates using mobile platforms capable of operating over these scales. Furthermore, an increased
demand exists for platforms that can collect co-registered data and samples throughout the vertical water column
including the seafloor and air-sea interface, thereby enabling us to understand coupling between all ocean realms.
While gliders and Lagrangian floats are used in most oceans, except in ice-covered seas where results are rarer, their
capabilities can be complemented by other mobile assets. Examples include autonomous underwater vehicles (AUVs)
capable of short duration but sensor rich observations, as well as emerging technologies -- e.g., long-range AUVs suitable
for long-duration studies, hybrid ROVs capable of providing high-resolution observation and intervention capabilities in
regions traditionally difficult to access, and ice-tethered profilers in the ice-covered oceans. This session seeks to bring
together scientists and technologists to (1) report science successes with these platforms; (2) demonstrate emerging
capabilities (e.g., sensing, sampling, platforms, communications, autonomy, long range navigation); and (3) highlight
challenges and opportunities for improved ocean observations. Communications of field results with these systems are
encouraged including preliminary results of potentially high-impact systems and science.

Session Title: Ocean Ecology and Biogeochemisty from Space: Next Generation
Session Description: In the thirty five years since the launch of the Color Zone Color Scanner, great strides have been
made to interpret remote sensing data and provide a better understanding of ocean biology and biogeochemistry. Next
generation instruments and technologies will address user needs for an improved view of the ocean. For example, lidar
and hyperspectral ocean color data will allow us to see deeper into the ocean and provide new opportunities to observe
the oceans at a resolution not currently possible. Furthermore, polarimetry can improve the characterization of ocean
particle compositions and atmospheric corrections for ocean color retrievals. This session aims to explore the most
current ocean observing technology and its potential for advancing quantitative ocean biogeochemical propreties. We
invite abstracts that focus onexperimental results using the latest observing technologies (in-situ or remote platforms)
addressing topics of ocean biology, chemistry, and air-sea interactions.

Session Title: Interactive Effects of Global Warming and Low Oxygen Stress: Temperature Regulation of Dissolved
Oxygen Supply and Respiratory Oxygen Demand in Pelagic Food Webs
Session Description: Temperature directly influences oxygen solubility in seawater as well as the metabolic demand of
aquatic ectotherms. To effectively assess the impacts of hypoxic stress, it is necessary to consider the effects of
temperature on both oxygen availability and animal metabolism. An underlying theory to predict effects of hypoxia that
allows quantitative comparisons across ocean ecosystems remains elusive, particularly for pelagic organisms. Oxygen
concentration alone is not sufficient to categorize hypoxia biologically and not all hypoxia is equal. Temperature is an
essential component defining hypoxic conditions, thus geographic, seasonal and inter-annual differences in temperature
can dramatically impact the severity of hypoxia even at similar oxygen concentrations. This session will emphasize
developing a unifying approach to assess the impacts of hypoxia by fully considering the multiple effects of temperature
on oxygen availability and animal metabolism across multiple temporal and spatial scales. In order to assess the effects
of globally expanding low oxygen zones, we propose to bring together physiologists and biological oceanographers that
focus on field observations and experiments as well as ecological modelers to review and expand our analysis of the
temperature controls of oxygen availability and demand by zooplankton and their fish predators.

organism behavior, interactions, recruitment, reproduction, and community structure. Relevant studies span topics of
biomechanics, transport and settling, propulsion, and sensory ecology. Themes may include the influence of
instantaneous flow patterns, the influence of extreme physical events, the influence of scale on the biological-physical
coupling, and biological/ecological advantages mediated by flow and chemical transport. For instance, what can we
learn from how organisms balance physical versus biological forcing? We invite studies addressing a broad range of flow
regimes spanning creeping, laminar, unsteady, wavy, and turbulent flows.

Session Title: Bioconstructors and climate change: from individuals to ecosystems
Session Description: Many organisms, from plants to animals, build bioconstructions. Bioconstructions can be highly
dynamic, involving skeletal growth processes and biotic interactions established among co-occurring species. They are
important to habitat building and greatly increase benthic diversity by providing hard substrate for other organisms to
settle on. These roles as habitat builders and nursery areas will become increasingly important in the face of marine
climate change (warming, ocean acidification, multiple stressors). Importantly, the effects of climate changes on their
structure (skeletal resistance and composition) and physiology will likely affect the biodiversity and in some cases the
economy of the coastal populations.
We invite oral and poster contributions that investigate the effects of climate change on bioconstructor species at all
scales, from physiological or structural to community responses.

it spans from study of free and attached unicellular organisms to a range of multicellular invertebrates (especially
worms!), from the deep sea to intertidal, and from sediments to the water column. Accordingly, this session welcomes a
broad range of studies that identify limitations in theory or experimental capability and apply new theoretical
frameworks or develop novel techniques. We seek reports of mechanistic approaches leading to advances in
understanding of feeding, digestion, and locomotion by infaunal and planktonic organisms, animal-sediment
interactions, and impacts of fluid dynamics on ecological functions of organisms. To honor Pete’s role as an outstanding
mentor, we seek new approaches in education and promotion of ASLO and ocean sciences to policy-makers.
Contributions are welcomed from scientists and educators inspired by Pete’s work, especially those focused on
interactions of organisms and environments that highlight novel syntheses or theory, application of other fields to
ecological questions, and integration of theory with experiment.

Session Title: Integrated Assessments of Vulnerable Deep-Sea Ecosystems: Methods, Recent Advances and Future
Challenges
Session Description: Deep-sea ecosystems at complex topography (e.g. ridges, canyons, carbonate mounds, seamounts)
are prominent features of the world’s oceans and provide valuable goods and services, such as biodiversity, climate
91 | P a g e
regulation and provision of natural products and food. Human activities increasingly affect the deep-sea, through the
exploitation of living (e.g fisheries) and non-living (e.g. deep-sea mining) resources or deep-sea pollution. The dynamics
of deep-sea ecosystems at different temporal and spatial scales and the environmental consequences of exploiting
deep-sea resources are far from understood. Improving our knowledge of deep-sea ecosystem dynamics and variability
is imperative for weighing risks against benefits of anthropogenic activities in the deep-sea. Recent advances in hydroacoustic seabed mapping, habitat imaging, in-situ observatories and modelling provide high quality datasets linking the
geosphere, biosphere and hydrosphere, and resolving deep-sea ecosystem structure and variability across multiple time
scales. This session aims to review the current state-of-the-art in integrated deep-sea ecosystem assessments and
discuss novel approaches based on observational and modelling techniques. Contributions from any part of this scope of
deep-sea environmental research are welcome in this session. We particularly encourage contributions addressing the
capacity of deep-sea monitoring and habitat mapping for improving dynamical and statistical modelling tools (e.g.
species distribution models).

Session Title: Utilizing biogeochemistry to understand the biological consequences of global ocean change
Session Description: As anthropogenic forcing of marine systems continues to accelerate, biological responses will have
dramatic consequences for the structure and function of marine ecosystems. A solid foundation of work has been laid,
focusing on understanding biological responses to changing ocean conditions. Most recently, the incorporation of
biogeochemical tools into the study of global change biology offers new, interdisciplinary insights. This session will focus
on the utilization of biogeochemical tools, such as stable isotopes and trace elements, to characterize the biological
consequences of global ocean change (e.g.warming, acidification, deoxygenation, eutrophication, nanoparticles). We
invite contributions on a range of topics including (1) organismal response to changes in abiotic conditions over
ecological and geological timescales, (2) links between environmental exposures and organismal performance, and (3)
biophysical feedbacks. We particularly welcome contributions that make connections across levels of organization
(molecular to global-level processes) spatial scales, (nm-km) and temporal scales (past, present, future).

Session Title: The Individuality of the Plankton: Single-cell analysis and agent-based modeling
Session Description: Fascinating advances in individual and single cell analytical techniques (e.g., flow cytometry,
chemical analyses, genomics) are providing an unprecedented view into the individuality of planktonic organisms (viro-,
bacterio-, phyto- and zoo-plankton). Plankton populations, which have traditionally been viewed as homogeneous
collections of individuals with identical properties and behavior, are now recognized to be heterogeneous, even in
environments commonly considered to be well mixed, like the open ocean. At the same time, agent-based modeling
(ABM, aka individual-based modeling, IBM) technology is evolving as a powerful approach to analyze and interpret these
observations. These models provide insights into the mechanisms underlying the heterogeneity (e.g., mutations,
stochastic gene expression, deterministic aging, microscale patchiness) and put them into ecological context (e.g.,
fitness benefits of bet hedging strategies). The combination of individual and single cell analyses and ABM has the
potential to transform plankton and microbial ecology across the freshwater-marine continuum and in other
environments. In this session, we aim to bring together scientists to share individual and single-cell research, to take a
snapshot of the state-of-the-science in this field, and to connect researchers with synergistic skills and interests.

Session Title: Big Data In Marine Ecology: Advances and Applications
Session Description: In recent decades, the rise of computing technologies and methods for high-throughput sampling
have been both a response to and a generator of emergent biological and ecological questions. These technologies have
93 | P a g e
helped to connect local and global scales of investigation in many fields including marine connectivity, evolutionary
ecology, pelagic food-web interactions, and responses of marine biota to climate change. Accordingly, biologists are
increasingly facing issues associated with “Big Data”: higher volumes (the scale of data in bytes or data points), velocities
(the rate at which data arrives), and variety(the different types, or sources of data), while verifying itsveracity (issues of
data quality). This session will examine 1) outstanding scientific questions and processes that necessitate the acquisition
of large datasets, 2) the power of big data in ecological inferences, 3) new methods for the visualization and analysis of
large datasets in ecological applications, and 4) novel and interdisciplinary methods of data collection and processing
(e.g. citizen science, crowd-sourcing, competitions, etc). We intend for this session to be cross-cutting, and thus invite
submissions from many fields, including imaging, acoustics, (meta)genomics, modeling, and eco-informatics.

Session Title: Physical-Biological Interactions at Ocean Fronts: from Processes to Predators
Session Description: Ocean fronts are sharp horizontal gradients in physical properties such as temperature, salinity and
density. Fronts manifest throughout the oceans over a range of spatio-temporal scales, from ephemeral sub-mesoscale
features in shelf seas to persistent basin-scale water mass boundaries in the open oceans. Under certain conditions, biophysical coupling along fronts can lead to enhanced primary productivity and the aggregation of zooplankton and
micronekton. This low trophic level enhancement is known to attract marine predators such as seabirds, turtles, sharks
and tuna to front-associated foraging and migration habitats. However, key questions remain regarding the
mechanisms through which the physical properties of fronts interact with prey field dynamics and the foraging ecology
of marine predators to influence associations. A better understanding of the physical-biological interactions that occur
at fronts, and the influence of spatial scale, frontal persistence and wider regional oceanography is required to ascertain
their ecological importance, and predict future shifts in critical predator habitats. This session seeks to gather
researchers to share new insights into physical-biological interactions at fronts in pelagic systems. We particularly
encourage inter-disciplinary presentations that integrate model-derived or remotely-sensed oceanographic data with
biological indices to elucidate the mechanistic links between physical processes, predators and prey.

Session Title: Modeling and observing the spatio-temporal structure of plankton ecosystems and its impacts
Session Description: New instruments and satellite technology have recently revealed unprecedented detail in the
structure of phytoplankton distributions at both micro and large scales, providing new insights into planktonic
ecosystems. For example, a microstructure profiler equipped with a new laser fluorescence probe resolves the highly
intermittent organisation of phytoplankton into millimeter-scale aggregates and larger-scale thin layers. At much larger
scales, satellite observations processed by sophisticated algorithms capture phytoplankton community structure and cell
size distributions. Contrary to the assumptions of nearly all large-scale models, the distribution of phytoplankton is far
from uniform at scales from millimeters to meters. Meanwhile, recent modeling studies have added new insights into
the response of plankton ecosystems by considering that plankton traits, including flexible physiology, have evolved
subject to fundamental trade-offs under changing environmental conditions. However, for the most part such studies
have not explicitly considered the spatio-temporal organization revealed by recent observations. In order to capture
mechanistically the flexible response of lower-trophic ecosystems to environmental change, models need to account for
realistic distributions of plankton and nutrients. We invite presentations of new approaches applying models,
observations, and model-data comparisons to understand the spatio-temporal structure of plankton in the natural
environment and its impact on ecosystem response.

Session Title: Assessing Ecosystem Variability from Paleoceanographic Archives
Session Description: The assessment of climate-change impacts on marine ecosystems is currently significantly
hampered by the lack of a sufficient number of long-term observations. Marine sedimentary archives provide a unique
opportunity to obtain information on the magnitude of ecosystem variability, trends, changes of biogeographic ranges,
and the extinction and emergence of species. Moreover, the analysis of ecosystem variability on longer timescales can
inform about the response to known climate forcings as well as, for example, on the existence and occurrence to
thresholds in ecosystems. Over the past years, progress in the development of proxies informing on key aspects of
marine ecosystems as well as in obtaining high-resolution sedimentary sequences has opened new opportunities in
marine-based paleo-ecosystem research. We invite contributions from all areas of paleo-ecosystem research, covering
high-resolution reconstructions, proxy development, and modeling studies.

Session Title: Ecosystem responses to climate variability in eastern boundary upwelling ecosystems
Session Description: The ocean’s mid-latitude eastern boundary currents support elevated levels of primary and
secondary production that sustain lucrative fisheries and attract an abundance of top predators. However, populations
in these systems exhibit high degrees of variability in productivity and/or distribution at interannual to multidecadal
time scales, challenging efforts to describe ecosystem health and develop effective strategies of resource management.
Coupling between physical and ecological processes in eastern boundary current systems has stimulated
multidisciplinary studies that aim to better describe the sensitivity of biogeochemical properties and biological
communities to climate variability and climate change. Variability in the intensity, spatial distribution, and seasonal
timing of wind-driven upwelling, changes in vertical stratification and mixing of the water column, differences in
mesoscale and submesoscale features, and changes in the biogeochemical properties of these regions’ deep source
waters have been proposed as critical factors influencing temporal variability in ecosystem conditions. In this session,
we welcome presentations highlighting work (observational, conceptual, and/or numerical) contributing to better
understanding of the dynamics of ecosystem response to climatic (both natural and anthropogenic) and hydrographic
changes in eastern boundary current upwelling systems over interannual to centennial scales.

Session Title: Plankton diversity: patterns, processes, and methods
Session Description: Recent field, laboratory, modeling, and theoretical efforts have improved understanding of the
patterns of plankton diversity and the mechanisms that maintain them, as well as the broader importance of diversity in
setting ecosystem properties and functions. Despite significant progress, considerable research challenges and
uncertainties remain. For this session, we invite contributions addressing these and related fundamental questions: How
is plankton diversity measured, manipulated, and modeled?; What are the observed and simulated patterns of plankton
diversity?; What controls the diversity of plankton?; and, How does diversity affect broader ecosystem properties and
functions? We welcome contributions from any methodological approach focusing on any aquatic system or taxonomic
groups. We particularly encourage studies that diagnose and interpret spatial and temporal diversity gradients across a
range of scales and organisms, and examine the dynamic interplay between physical and biological processes. The goals
of the session are to: a) build understanding of the patterns, regulation, and importance of plankton diversity, b)
highlight areas of persistent uncertainty as focal areas for future research, and c) provide an interdisciplinary forum for
communicating novel methodological and conceptual developments in the study of plankton diversity.

Session Title: Impacts of ecological interactions on marine ecosystem dynamics: New insights from models, theory, and
field measurements
Session Description: Ocean ecosystems make up the largest living space on the planet. Understanding the behavior,
physiology, and evolution of marine organisms in the context of their chemical and physical environments and species
interactions is key advancing our understanding of community and ecosystem functioning across systems. Multiple
general concepts in ecology have originated from pelagic systems, including ecological stoichiometry, trophic cascades,
and the match/mismatch hypothesis. However, a fundamental hurdle in advancing our understanding of ecological
processes in the ocean remains the traditional boundary between ecology and oceanography. In this session, we seek to
bring together those posing questions about pelagic ocean ecosystems, bridging empirical investigations with ecological
theory and process models. We welcome both theoretical and empirical research addressing ecological interactions
across a range of scales and trophic levels, with particular emphasis on the integration of field sampling, ecological
theory, and/or modeling aimed to reveal processes structuring ocean ecosystems.

Session Title: Ecological Consequences of Internal Waves, Internal Tides and Solitons in the Ocean
Session Description: At the crossroads of physics and geology, nonlinear internal waves (NLIWs) are generated where
currents in a density-stratified water column intersect with topography. They are ubiquitous in the ocean and contribute
significantly to physical mixing, biological productivity and benthic biodiversity across a wide range of scales, from
diurnal internal tides to packets of solitons. Changes in stratification might alter NLIW energetics in the future ocean, but
the consequences for the biota are at present unknown. Here, we invite contributions linking NLIW dynamics to pelagic
productivity and export to the benthos, aggregation and transport of food and propagules, shoaling of NLIWs,
propagation of bores and the consequences of the resulting environmental variability on pelagic and benthic biota. Field,
laboratory and modelling studies linking the physics, geology and biology across a full range of marine ecosystems are
welcome.

Session Title: Interaction of Physical and Biological Systems in the Ocean
Session Description: The session invites a broad range of interdisciplinary papers addressing interactions of physical and
biological systems in the ocean and offering more accurate understanding of marine ecosystems as a whole. It is
understood that physical oceanographic features, such as oceanic currents, jets, eddies, etc. can influence distributions
of organisms at the base of food webs as well as distributions and dispersal pathways of larval and adult fish, and other
marine organisms. Examples of such bio-physical interactions include, among others, the influence of the Gulf Stream on
movement of American eel larvae from the Sargasso Sea; effects of oceanic transport barriers on harmful algal blooms
near the West Florida Shelf; effects of the 2010 Deep Water Horizon oil spill on the sea turtle populations whose
movements intersected oil-rich areas; and avoidance of underwater oil plumes by sperm whales. Diverse observational
tools are required to collect data across spatiotemporal scales governing physical and biological processes, and
integrated bio-physical models are needed to understand and realistically represent the nature of those coupling
mechanisms. It is thus critically important to bring together researchers working at the interface of their disciplines to
encourage new, large-scale collaborations to study marine ecosystems as whole complex organisms.

Session Title: Exploring the Spatial and Temporal Scales of Marine Animal Response to Global Change
Session Description: As anthropogenic influences on marine environments increase, there is considerable scientific and
practical interest in understanding how animals will respond. There is increasing awareness, however, that
understanding how species will fare requires explorations of the interface between the response of individual organisms
to the suite of co-occurring stressors and larger scale variability in exposure and sensitivity. There are strong temporal
factors, such as adaptation and seasonality which interact with spatial components, such as connectivity and interpopulation variation in environment and sensitivity, that will influence the capacity of a species as a whole to cope with
environmental changes. New approaches, including studies of seasonality, application of time-series datasets,
comparative analyses across broad spatial scales, integration of circulation patterns, observations of the influence of
migration and dispersal on adaptation responses, and multi-generational experiments will pave the way for this more
nuanced understanding of species response. Innovative multidisciplinary approaches require opportunities for
researchers approaching these larger scale problems to interact, cross-fertilizing ideas. This session thus aims to bring
together studies applying a number of disciplines to characterize the influence of temporal and spatial variation on the
genetics, ecology and physiology of marine animals, particularly in the context of changing physical and chemical
landscapes.

be gleaned from examining its components in isolation. It can reveal mechanistic explanations of system dynamics in
space and time, and can be used to assess the vulnerability and resilience of a system. This session invites presentations
of research that applies network theory to marine systems, including studies of population connectivity, animal
movement patterns, food webs, the spread of disease, and the socio-ecological aspects of managing marine resources,
including marine reserves. The session will provide a space for researchers to exchange ideas, techniques, and new
developments in applying network analysis to marine science.

Session Title: Exploring biological-geological interactions in coastal and nearshore habitats
Session Description: The coastal and nearshore zones are some of Earth’s most heterogeneous and dynamic geological
environments, directly influenced by both terrestrial and oceanographic processes. These environments, which are
economically and societally important, host a variety of ecosystems and are critical habitats to many marine species.
Many of the ecological processes that occur in the intertidal and subtidal zones involve close physical and/or chemical
interactions between the organisms and the geologic substratum. There are a vast number of species and biological
assemblages that are intimately associated with substrata. Classic examples include rocky intertidal communities and
giant kelp. This interdisciplinary session aims at bringing together geologists and biologists who are exploring biologicalgeological interactions in coastal and nearshore habitats across multiple spatial scales using both classic and novel
methods of scientific investigation. We especially encourage the submission of multidisciplinary, educational, and
outreach-oriented topics.

Session Title: Toward Mechanistic Understanding and Prediction of Abrupt Ecosystem Changes
Session Description: Ecosystems can experience abrupt changes in productivity, species composition and trophic
structure that can profoundly impact marine resources and undermine resource management. Such changes often
arise from shifts in multiple ecosystem drivers (e.g., climate forcing, pollution, fishing, acidification) that are integrated
within complex communities. Dynamical systems theory has provided fundamental insights into the nature and drivers
101 | P a g e
of abrupt ecosystem change - including potential early warning signals. However, greater process-level understanding of
drivers and mechanisms underlying abrupt ecosystem changes are essential for robust prediction. In this session, we
invite observational and modeling studies elucidating the processes and mechanisms underlying abrupt ecosystem
changes.

Session Title: Scaling up: Marine infectious diseases from the molecule to the ecosystem
Session Description: Infectious diseases are key drivers that shape local biodiversity and are becoming increasingly
important as anthropogenic change exacerbates disease processes. Despite this, parasites and pathogens are commonly
overlooked or under-appreciated as drivers of ecology and biodiversity in many ecosystems. The establishment, severity,
and outcome of disease are governed by numerous interactions within the host-pathogen-environment paradigm. A
shift in these factors can lead to or away from a diseased state, and disease emergence is modulated by this interplay.
The factors that impact disease outbreaks and severity occur across many scales of magnitude, from viruses-antigen
interactions, to trait- and density-mediated responses of hosts to pathogens, to regional and global environmental
oscillations. Understanding how processes interact across these scales to alter epidemiological patterns is an important
challenge, for which numerous new multidisciplinary fields are emerging, including molecular epidemiology, ecoimmunology, and ‘big data’ approaches. In this session, we invite contributions that investigate marine diseases across
scales. Student participation is highly encouraged.

Session Title: Resolving OMZ processes: single-cells to ecosystems, coasts to open ocean
Session Description: Areas of low oxygen have spread dramatically over the past 40 years and represent a significant
ecosystem perturbation. The formation and persistence of both natural and anthropogenically induced oxygen minimum
zones (OMZs) result from linkages among physical, chemical and biological processes. OMZs are spatially diverse and
found worldwide in marine environments, particularly in upwelling or nutrient rich coastal systems. In these OMZs,
oxygen is consumed more rapidly than it is resupplied, and declining oxygen concentrations result in a shift from aerobic
to anaerobic metabolisms. This transition can result in production of potent greenhouse gasses such as methane and
nitrous oxide. Thus, OMZs represent a potential positive feedback loop for global warming. This session will explore the
current state of knowledge on OMZs, scaling from genes and transcripts to microbial cells and populations, and finally to
whole ecosystems in coastal and open ocean OMZs. Of particular interest is work that integrates biological, chemical
and/or physical data across micro to macro-spatial scales. Contributions are encouraged from biologists across all
ecological levels, and from both chemical and physical oceanographers studying regions of low dissolved oxygen.

and change on marine ecosystems from the surface to the benthos. Climate-related parameters (e.g. ocean
temperature, salinity, turbidity, stratification, currents, coastal precipitation, runoff, inundation, pH, etc.) can directly
and indirectly affect marine ecosystem conditions. These changes are likely to impact the abundance, distribution, and
103 | P a g e
productivity of the organisms composing the ecosystem, some that support economically important fisheries. Many of
these changes remain undocumented or not rigorously evaluated especially between the Equator and the cooler
temperate zones, perhaps due to their subtle nature.
This session encourages contributions that illustrate that climate change is affecting marine ecosystems including
people from the surface pelagic realm to the marine benthos. Of particular interest are: 1) biogeographic shifts and
timing of life history behaviors (phenology) in response to changing water temperatures; 2) changing hydrodynamics
and forcing (locally, regionally and oceanic); 3) ocean acidification; 4) changing geochemical conditions (e.g. salinity,
turbidity, chlorophyll, other optical); and 5) sea level rise.

Session Title: Pacific Ocean anomalies of 2014-2015: Consequences for Marine Ecosystems
Session Description: Unusual atmospheric and ocean conditions existed across much of the North Pacific Basin in 2014
and early 2015, especially in middle to high latitudes. Sea surface temperature anomalies reached >2.5º C in the central
Gulf of Alaska and it has been suggested that these conditions are related to an unusually strong and persistent pattern
of much higher than normal sea level pressure in the region. The pattern of strong positive SST anomalies has been
referred to colloquially as ‘the blob.’ Elsewhere, in parts of the California Current System, temperature anomalies
exceeded 5º C. Numerous biological perturbations have been suggested to be associated with the NE Pacific
ocean/atmosphere anomalies, including depressed Chl-aconcentrations, geographic shifts of zooplankton and other
taxa, reduced biomass of some small pelagic fishes, increased pinniped strandings, altered breeding success and
survivorship of some seabirds, and others. This session invites contributions pertaining to either physical ocean and
atmospheric conditions during 2014-2015, or evidence for biological and biogeochemical responses (or lack thereof) to
these anomalies. Both observational evidence (especially in the context of longer term records) and models
representing the dynamical basis of the anomalous conditions and underlying responses are encouraged.

Session Title: Plankton Grazing and Selectivity in Marine Food Webs
Session Description: Grazing by heterotrophic plankton is a key process that mediates the flow of energy and material
through planktonic food webs, yet is poorly parameterized in many food web and biogeochemical models. Various
methods have been used to measure grazing empirically, including prey removal experiments, gut content studies, and
biochemical analyses, each with its own advantages and challenges. Additionally, many studies use bulk relationships
between grazers and prey to describe and measure grazing, and as such, we still often have rather course resolution for
parameterizing complex food web models. Yet it is widely accepted that marine planktonic grazers are highly selective,
and the mechano- and chemosensory mechanisms of that selective behavior are not well understood or constrained.
This session seeks to bring together a wide array of research on planktonic grazing and the selectivity of grazers, in an
effort to explore broad questions of the role of grazers in structuring food webs and communities. Our goal is a varied
set of presentations on a variety of aspects of grazing to gain insight into the impacts of this process on our
understanding of marine ecosystem dynamics. We welcome presentations from any work related to grazing, including
experiments, observations, or modeling.

Session Title: Hydrocarbon seepage as a conduit connecting deep subsurface sediments, shallow sediments, the water
column, and atmosphere
Session Description: Cold seeps are broadly distributed along active and passive continental margins. At these seeps,
hydrocarbons migrate from shallow or ultra-deep reservoirs through fault networks that penetrate sediment packages,
releasing hydrocarbons from the seabed through slow, diffuse seeps as well as high flow vents. Hydrocarbons are
105 | P a g e
transformed biologically within the sediments during transport and after release into the water column. Hydrocarbon
exposure affects patterns of microbial community structure and activity in sediments and the water column.
Additionally, these fluxes also can promote physical mixing, potentially altering nutrient and material fluxes through the
water column. Water column processes serve as the final biological filter than can consume hydrocarbons ranging from
simple gases (e.g., methane) to petroleum (e.g. alkanes and polycyclic aromatic hydrocarbons), and prevent them from
reaching the sea surface and atmosphere. Nonetheless, the patterns, rates and regulation of microbial hydrocarbon
oxidation in sediments and the water column remain poorly constrained. This session will highlight recent advances in
hydrocarbon dynamics at cold seeps, including the geological, physical, biological, and environmental factors that
regulate the fate of hydrocarbons in oceanic environments. This session will target an interdisciplinary audience to
provide a holistic understanding of hydrocarbon cycling in sediments and waters across diverse systems.

Session Title: Oceans and Human Health: Improving Ecological Forecasting of Marine Microbes
Session Description: Oceans and human health are intimately connected. Human activities resulting in pollution,
temperature and salinity changes, among others, affect the health of the ocean. Conversely the ocean and Great Lakes
affects human health in positive and negative ways. Potential goods and services derived from the ocean include but is
not limited to food and the discovery of new medicines and natural products. Negative impacts include, but are not
limited to, diseases contracted through various mechanisms: direct contact, food and drinking water ingestion, and air
inhalation. Marine microbes, ubiquitous throughout the marine environment, play many varied roles and may affect
human health directly or indirectly. Marine microorganisms broadly include microalgae, bacteria, protozoa and viruses.
Recent successes in forecasting conditions favorable to the bloom of harmful algae or the presence of Vibrios and other
pathogens in our coastal and ocean waters emphasize the importance of the ecological forecasting efforts. This session
will explore worldwide advances in the ecological forecasting for marine microbes ranging from harmful algal blooms to
pathogens.

Session Title: Microbial and geochemical dynamics of deep, hypersaline anoxic basins
Session Description: Hypersaline ecosystems offer rich targets for deep-sea exploration and discovery, and this
interdisciplinary session will highlight recent transformative discoveries from such habitats. Deep hypersaline anoxic
basins (DHABs) occur worldwide in locations where ancient salt deposits come into contact with seawater, leading to
salt dissolution and formation of dense brines. Upward movement of brines, either through slow advection through
sediments or violent eruption at mud volcanoes, significantly alters the biogeochemical signatures of benthic habitats
and creates distinct surficial habitats and interfaces defined by strong salinity gradients. Because brines are denser than
seawater, they may form brine pools in seafloor depressions, or move along and across the seafloor in brine flows within
topographic lows. The physical and geochemical characteristics of brines vary tremendously across and within systems.
These variations in physical and geochemical characteristics create unique extreme habitats that support diverse and
novel microbial communities that mediate a number of discrete and unusual metabolisms. This session will attract talks
and posters that address the fundamental geologic processes that lead to brine formation and flow, that quantify the
geochemistry, microbiology, microbial processes, and macrobiology of brine ecosystems, and that compare and contrast
the geochemistry and biology of different brine environments.

Session Title: Microbial Biogeochemistry of Hydrothermal Vents in Shallow and Deep Waters: Commonalities and
Differences
Session Description: Submarine hydrothermal systems in shallow- and deep-water are both the result of volcanic or
tectonic activity, hosting habitats that are strongly driven by geophysical and geochemical extremes operating on a wide
range of spatial scales. Yet, both systems are often studied in separation. This session intends to bridge this gap and
seeks contributions from shallow and deep-sea vent systems, covering geochemistry and microbiology, examining
specifically the hydrothermal effects on microbial diversity and function and the impact of microbial activity on fluid
composition. The session aims at synthesizing the knowledge from both systems and at building a ‘toolbox’ to use
geochemical parameters to predict community composition and functioning in submarine hydrothermal systems, based
on observations, experimental work and models. Conversely, the session shall also enhance our understanding of the
impact of microbial activity on chemical fluxes of both inorganic and organic constituents within hydrothermal systems
and on the surrounding ocean. We also encourage contributions focusing on the potential significance of hydrothermal
vents as sites for the origin of life and as potential analogs for life elsewhere in the universe.

Session Title: Frontiers in Ocean Color Remote Sensing: Science and Challenges
Session Description: The advent of satellite oceanography in late 1970's has given rise to a realization that our ocean
plays a critical role in weather, climate and sustaining life on Earth. Satellites have revolutionized our understanding of
linkages among the ocean and other components of the Earth system and have revealed a diversity and complexity in
ocean ecosystems not previously appreciated. Further, the explosive growth of human populations along coastal
margins places increasing pressure on these ecosystems, modifying natural processes and putting life, health, and
property at risk from hazards inherent to the ocean. Scientific observations from the vantage point of space help solve
important problems. Advanced technologies and frequent, repeated, multi-scale satellite observations, in combination
with field measurements, are essential for observing and predicting changes.
Without global ocean color satellite data, humanity loses its capacity to take Earth’s pulse, explore its unseen world, and
monitor our living marine resources. This session explores the next generation of ocean science questions from satellites
and challenges to those observations from science, technology, and modeling perspectives. Our goal is not only to
understand and monitor the Earth’s changing climate and ecosystems, but also to enable the next generation of
students to make new discoveries.

Session Title: Advances in the ecology, behavior, physiology, or conservation of marine top predators
Session Description: Top predators are a vital part of the marine ecosystem, and as such, their ecology, behavior and
physiology can influence important processes such as trophic interactions, carbon flow, and nutrient recycling. Virtually
all top predators have a history of over-exploitation or they have special management status because of their sensitivity
to marine industrial activities and other human uses (e.g., bycatch, shipping, resource exploration/extraction). Basic
research on top predators often focuses on gaps in our understanding of their ecology, but unlike many other branches
of biological oceanography, research can also be motivated directly by management and conservation needs. This
session will focus on studies of the ecology, behavior, and physiology of marine top predators that either advance our
scientific understanding or support the conservation of these important taxa. Because Ocean Sciences provides a
unique forum for marine ecologists, marine biologists, and oceanographers to interact, we seek contributions from
researchers studying a wide variety of taxa, including fish, squid, reptiles, seabirds, and marine mammals, from
anywhere in the world’s oceans.

Session Title: Ocean Exploration of Atlantic Canyons: Summary and Results of Recent Cruises
Session Description: In response to emerging science and management drivers for data and information from shelf and
slope habitats, the U.S. National Oceanic and Atmospheric Administration (NOAA) in collaboration with its federal (e.g.,
109 | P a g e
Bureau of Ocean Energy Management, U.S. Geological Survey) and academic partners focused a variety of ship and
submersible assets on the US Atlantic canyons between 2011 and 2014. The data and information acquired from more
than 23 cruises have provided a wealth of new knowledge to scientists and managers interested in these critical offshore
habitats. Over four field seasons, the complementary capabilities of ships and camera systems were applied to acquire
high resolution multibeam data over nearly all of the U.S. Atlantic Canyons and used submersibles to examine the
diversity and distribution of deep-sea habitats - including deep coral and seep communities. This session will summarize
the cruises and will highlight the results obtained by our partners and collaborators and will compare our results with
those obtained by the ocean community at large (national and international) as a result of Atlantic exploration cruises.

Session Title: Geology and ecology of deep-sea interfaces: a holistic approach to understanding complex submarine
canyons and seamount environments
Session Description: Submarine canyons and seamounts are topographically, geologically, and oceanographically
complex features with environmental characteristics (e.g., substrate types, carbon flux, and current patterns) that vary
greatly along continental margins and across seamount chains. Differences in environmental characteristics may
influence community structure among adjacent canyons or seamounts, yet we know little about what controls these
factors have across multiple spatial scales. The dynamic nature of these environments, including intense currents,
variability in upwelling conditions and nutrient transport, and substrate type and availability can all influence the habitat
suitability for benthic organisms, locally supporting high species biodiversity, biomass or both. Furthermore, they can
provide goods and services that are vital for the health and wellbeing of our planet and are vulnerable to impacts of
human activities and climate change. With a better understanding of environmental drivers, the intimate relationship
between sessile fauna and the exposed substrate in submarine canyons and on seamounts could provide a framework
for determining the relative age of geologic processes such as canyon wall and edifice failure and sediment transport
events. We invite contributions from researchers that investigate the complex relationships at the interface between
ecology, geology, chemistry and physical oceanography in these deep sea environments.

Session Title: Eulerian Versus Lagrangian Perspectives on Marine Ecosystem Change
Session Description: Climate change is altering our oceans, be it ocean acidification, warming temperatures, or altered
ocean currents, and these changes will impact marine species and the food webs that support local and global fisheries.
In the face of a changing ocean climate, marine species that currently occupy a particular place may move, may evolve
and adapt to the new conditions, or they may die. In this session we invite contributions that address this issue using
either Eulerian or Lagragian perspectives. The session will specifically focus on work that addresses the impact of climate
change on marine communities, and the ways in which communities may adapt, through the evolution of local types
and/or the immigration of new types from other areas. Will warming waters drive certain species to extirpation, or will
connectivity maintain local populations? What is the role of evolution relative to shifting species distributions? Which
places are likely to be thermal-refugia, which places are likely to become biodiversity deserts? We anticipate
presentations that address these questions to be both theoretical and empirical, and also to discuss what this means for
us, in terms of the marine ecosystem services that we rely on for sustained wellbeing now and in the future.

Session Title: Evaluating short and long-term ocean model predictions for fisheries management
Session Description: A critical step to predict the impacts of natural events and climate change on marine populations is
to select accurate environmental predictors at appropriate resolutions. Use of ocean models is increasingly popular for
this purpose. However, statistical evaluation of the accuracy and applicability of numerical models, and their
contribution to overall error in ecological models are rarely completed. In addition, the gains from implementing high111 | P a g e
resolution versus less-costly low-resolution numerical models are not always considered. We will invite presentations on
studies and models covering a range of species, ecosystems, and spatiotemporal scales (e.g. data assimilative model
reanalysis, real-time experiments, short-term forecasts, and long-term (climate) forecasts). A particular focus area will
be submesoscale instabilities in the marine environment, including how they are connected to both larger scale and
smaller scale motions, and to what extent they influence environmental variability and transport processes in the ocean.
We will bring together interdisciplinary ocean modelers and fisheries oceanographers to discuss these issues, learn from
each other, and plan how to improve both the predictive skill of ocean models and the management of marine
resources.

Session Title: Ocean Deoxygenation: Integrating Coastal and Oceanic Perspectives
Session Description: Deoxygenation of coastal and oceanic waters is one of the major manifestations of global change.
But there have generally been two separate schools of study - one that addresses eutrophication-induced hypoxia in
coastal ecosystems and another that examines naturally occurring oceanic hypoxic zones (including oxygen minimum
and limiting zones, and their shoaling into coastal habitats). Both forms are, however, predicted to worsen with
increasing temperatures, are affected by surface layer productivity, and affect physiological processes, animal
movement and fishing practices. In this session, we hope to bring these two groups of researchers together to develop a
better understanding of the commonalities and differences in different types of hypoxic systems, and to examine where
and how these realms interact. We especially encourage talks that, either individually or by clustering contributions,
consider similar processes in different types of systems or examine interfaces. Contributions on predicted patterns of
hypoxia, adaptation to hypoxia, and the effects of hypoxia are welcomed.

Session Title: Multi-model approaches to ecosystem-based management of aquatic ecosystems
Session Description: Ecosystem Based Management (EBM) is widely accepted by scientists, managers and policy makers
as important for the conservation and management of natural resources. Ocean-based EBM ranges from consideration
of environmental influences in single-species stock assessments (i.e., Ecosystem Approaches to Management) to
complex multi-sector trade-off analyses. Risk and trade-off analyses in natural resource management are intimately
associated with the analysis of uncertainty and include evaluation of policies that are most robust over the full suite of
alternative future conditions given uncertainty about the behavior of a system. Multi-model inference is a powerful
approach for synthesizing disparate model projections and transdisciplinary information relevant to aquatic ecosystem
management.
In this session we invite presentations describing multi-model approaches to inform aquatic ecosystem management
across all sectors: fisheries, spatial planning, coastal development, transportation, conservation, etc. Of particular
interest are modeling efforts that • connect changes in the biophysical system to changes in human wellbeing;
• evaluate the strengths, limitations, and caveats of alternative modeling approaches,
• analyze possible ecosystem or population responses to human activities and environmental drivers; or
• provide managers and policy makers with knowledge in a manner that promotes more informed decision making.

Session Title: Between a Rock and a Soft Place: Interfacial Dynamics on Reefs and Their Consequences for reef processes
Session Description: Interfaces in the marine environment are dominated by diffusive processes, but metabolic activity
influences the dynamics within the microenvironment created at these interfaces, both at the surface of an organism,
and within the organism itself. Because they are small, dynamic, and often isolated, microenvironments can be difficult
to characterize. Despite the small scale of microenvironments, they can have large impacts on the physiology of marine
113 | P a g e
organisms, species interactions, and large scale ecological processes on reefs. The purpose of this session is to bring
together researchers who are using unique methods to investigate the dynamics within microenvironments in reefdwelling organisms. Investigating these dynamics is essential to improving our understanding of the interplay between
physical, chemical, and biological processes influencing reef-dwellers, how they may be influenced by environmental
change, and the associated consequences for reef processes worldwide. We welcome abstracts related to interfacial
dynamics of any benthic marine organisms associated with reef structures.

Session Title: Sediment Dynamics of a Tropical River-Marine Dispersal System: the Mekong from River Source to Ocean
Sink
Session Description: The Mekong sediment dispersal system has a major impact on the landscape and seascape of
southeast Asia and on the people living there. Investigations of its operation are important for a basic understanding of
fluvial and deltaic sedimentation, and for preparing to deal with environmental change of many types (e.g., sea-level
rise, salt intrusion, river damming). Recent studies by a range of international scientists have provided a wealth of new
knowledge about the numerous interfaces along the continuum from fluvial to tidal-river to estuarine to coastal
(mangrove) to continental-shelf environments. Among recent advances are understanding of impacts on sedimentation
from: seasonal exchange between the river channel and floodplain; non-steady flow imparted by tidal influence;
modulation of estuarine processes with level of river discharge; variable wave energy impacting mangrove shorelines;
monsoonal circulation patterns controlling growth of the shelf clinoform. This session is an opportunity to present
recent results and integrate them into a comprehensive understanding of deltaic sedimentation and of the Mekong
system, in particular.

Session Title: Soil Mechanical and Hydrodynamic Processes of the Seabed Surface
Session Description: The uppermost seabed sediment layers are exposed to a number of different soil mechanical
processes such as shear forces, particle-to-particle interactions, sediment deposition and consolidation, and pore
pressure fluctuations in response to hydrodynamics. These processes depend on and influence the soil mechanical and
physical characteristics of the seabed surface, and thus, sediment transport, as well as the evolution of habitats or the
long-term fate of morphological features or offshore structure stability. An example is the pore pressure response to
different wave characteristics, and potential risks for sediment liquefaction and increased erosion or scour. Another one
is the impact of sediment characteristics on shear resistance and particle entrainment or consolidation behavior after
deposition, and the resulting consequences for morphodynamics. This session is aiming for contributions investigating
such processes and their impacts on sediment erosion and deposition processes in a coastal and marine environment.
The presentations will cover field exploration methods and case studies, routine and specialized laboratory testing of
coastal and marine seabed sediments, as well as numerical modeling of processes and environments.

Session Title: Response of Coastal Sedimentary Systems to Anthropogenic Alterations and Climate Change
Session Description: Coastal environments, located at the interface between terrestrial and marine processes, are
becoming more vulnerable due to climate change and human activities. These dynamic sedimentary systems operate
115 | P a g e
through a series of feedback loops responding to natural and anthropogenic alterations. The responses of these systems
vary widely over a range of spatial and temporal scales, and may be observed as geomorphological changes and/or
preserved within the sedimentary record. Increasing our understanding of how these systems respond, or have
responded in the past to natural and anthropogenic changes will be critical to the future sustainability of valuable
coastal ecosystems.
This session will broadly address sedimentation, and sediment dynamics of coastal systems such as estuaries, beaches,
marshes, and wetlands with a focus on the linkages between how environmental and sedimentary process are
preserved within the geologic record. Emphasis will be placed on how these coastal systems respond to natural changes
(e.g. climatic, tectonic, sea level, episodic storms) and anthropogenic alterations to the system, and how these changes
influence sedimentary dynamics and ultimately are preserved within the geologic record. We encourage submissions
that highlight these linkages through studies utilizing high-resolution geophysics, sediment and stratigraphic analyses,
field observations, and modeling among others.

Session Title: Sediment Delivery, Transport, and Deposition in Coastal Aquatic Environments
Session Description: Coastal aquatic environments are shallow and their waters are particularly susceptible to
environmental degradation in part because they often experience high loadings from rivers and shorelines. Expanding
populations have stressed these regions, and in many cases have contributed to increases in the frequency and severity
of unwanted effects, such as coastal erosion, hypoxia, harmful algal blooms, excess turbidity, and high rates of
sedimentation. These problems are often tied to sediment transport, because many nutrients and anthropogenic
pollutants are transported with sediments, and sediment-induced turbidity can limit the amount of light available for
photosynthesis and visual predators. Sediment transport in coastal waters can create deposits that in some cases are
modified or destroyed by subsequent events, while in others may be preserved in the geologic record.
Recent advances in theoretical, observational, and numerical modeling techniques have led to increased understanding
of the processes and products of sediment delivery, transport and depositional processes in shallow-water
environments; including continental shelves, estuaries, and lakes. This session showcases research relevant to these
environments covering physical forcing, sedimentary response, modes of transport, biogeochemical feedbacks with
sediment, particle behavior, and event stratigraphy. Studies may derive from field observations, laboratory
experiments, and modeling across a range of timescales.

Session Title: Mapping the oceans: co-ordinating seabed and habitat mapping for maritime spatial planning.
Session Description: Globally it is estimated that hydrographic maps are available for only 5% of the world’s oceans,
even less of which have been mapped geologically or to identify benthic habitats. Recent international reports place a
value of US$24 trillion on the raw economic value of the global oceans, two thirds of which rely directly on healthy
ocean conditions. Maritime planning, sustainable use of marine resources, and forecasting all need good maps, which is
now recognised by the growing number of national seabed mapping programmes and initiatives such as the Atlantic
Ocean Research Alliance launched by the European Union, the USA and Canada when these countries signed the
‘Galway Statement’. This session will investigate the scientific and technological progress in mapping the seabed,
addressing bathymetric mapping, which improves the safety of navigation in our seas, geological mapping, which
provides detailed knowledge of seabed/subseabed characteristics and identifies marine resources, and habitat mapping
which provides essential information for food security and the protection of the most vulnerable seabed communities
and ecosystems, to maintain healthy and biologically diverse oceans. The session will also address seabed mapping gaps
and challenges as well as data management and access to data and information products.

Session Title: Rates of ice retreat and insights into a warming Earth from Antarctic sedimentary and ice records - Dating,
chronology, regional correlations, and environmental change
Session Description: Antarctic ice, margin sediments, and Southern Ocean deep sea sediments contain records of the
last deglaciation that are important to interpreting current observations of ice mass loss in Antarctica. Many of these
records contain readily identifiable contacts between the Last Glacial Maximum and the Holocene, however dating these
contacts, providing chronologies for individual records, and correlating records across the Antarctic continent and
Southern Ocean remain problematic. Understanding of the timing of these events recording in ice and sediments is
critical to relate these records to northern hemisphere deglaciation records.
This session will seek presentations focused on aspects of dating, chronology, and regional correlation of Southern
Ocean and Antarctic records of deglaciation. We seek the latest developments in accurately and precisely dating
geologic records, new chronologies, and approaches to achieve regional to continental correlation, as well as
subsequent records of paleo-environmental changes. Abstracts focusing on data generation from records and modelling
efforts are welcome. From this session, we hope to achieve a better understanding of the timing of Antarctic
deglaciation and how it relates to global change at the end of the Last Glacial Maximum.

Session Title: Action! Microbial activity and interaction with organic and inorganic matter in the dark ocean
Session Description: The notion of low metabolic activity in the dark ocean is a view from the past. On the contrary,
meso- and bathypelagic microbes exhibit relatively high biomass production and respiration, variable enzyme activity,
and measurable fixation of inorganic carbon, manifesting that bacteria and archaea are a dynamic component in earth’s
largest habitat. In addition to a lack of data of major parts of the global open ocean, the quest now is to uncover the
source for this metabolic activity, deciphering the hot spots of dark ocean microbial interactions with organic matter in
all forms and the potential energy sources utilized.
This session invites contributions presenting the magnitude of bacterial and archaeal activity in the dark ocean,
indicating potential metabolic pathways on an omics level, addressing the relationship between microbes and the
118 | P a g e
organic matter pool, or linking the composition of organic and inorganic matter to microbial processes. Thus we seek to
paint an interdisciplinary picture of the microbial processes in the dark global ocean.

Session Title: New Methodological Approaches to Study the Microbiology and Biogeochemistry of Oxygen Deficient
Zones
Session Description: Oxygen deficient zones (e.g. eastern tropical Pacific, Arabian Sea, Baltic Sea, Black Sea, Cariaco
Basin) are intrinsic features of the modern oceans, expected to expand in the future due to climate change. These areas
harbor an unknown diversity of microorganisms involved in the C, N, S and metal cycles. The development of omic
techniques (metagenomics, transcriptomics, proteomics, lipidomics, metabolomics), as well as advances in
biogeochemical methods and modelling are giving some hints on the microbial diversity, activity, novel metabolisms,
and interactions between microorganisms inhabiting oxygen-deprived marine ecosystems. However, many unknowns
still remain on the structure of the microbial communities and the internal metabolic networks occurring in these unique
environments. To resolve the complexity of these systems a multidisciplinary approach is required. This session aims to
bring together microbiologists and biogeochemists and we welcome contributions related to the application of new
methodological approaches applied to oxygen-deficient marine systems.

Session Title: The hitchhiker’s guide to the aquatic realm: Microbial life on particles
119 | P a g e
Session Description: Particles of different sizes, origins and composition, including living, senescent and non-living
biomass, colloidal matter, as well as inorganic particles are ubiquitous in the water column. They constitute distinct
microenvironments enriched in organic and inorganic nutrients and are characterized by redox and oxygen gradients
where microorganisms can thrive. Commonly, microbial abundance and activity is orders of magnitude higher in these
microenvironments than in the surrounding water. Particle-associated microbes, including Bacteria and Archaea, viruses
and Protozoa have been shown to be metabolically and phylogenetically different from their free-living counterparts,
constituted by both adapted and opportunistic microbes. However, recent research is rapidly expanding our knowledge
on this underexplored habitat, e.g. its significance for deep-sea microbes, the reported association and interaction of
certain yet poorly known key organisms, such as members of the phylum Euryarchaeota, differential potential metabolic
pathways, mechanisms of viral adsorption, or the significance of quorum sensing and chemotaxis in this pelagic
microbial consortia.
This session intends to bring together aquatic microbial ecologists to discuss recent advances in our understanding of
microbial diversity and processes on pelagic particles and aggregates in aquatic ecosystems.

Session Title: Viruses in Aquatic Ecosystems: Diversity, Biogeochemistry, and Host Interactions
Session Description: Viruses are quantitatively significant components of aquatic ecosystems, where they cause
mortality of organisms from bacteria to whales. Research over the past 25 years has highlighted their critical roles in
aquatic biogeochemical cycles, maintaining or enhancing the biodiversity of their hosts, and in gene exchange between
individuals and populations of microorganisms. Aquatic viruses are also incredibly diverse as free particles in
virioplankton, as integrated temperate viruses and in association with the tissues of metazoans and higher animals. In
this session, we seek submissions addressing the abundance and diversity of viruses across aquatic ecosystems and in
association with hosts, and the impacts of viruses on host ecology and host-driven biogeochemistry. We also welcome
submissions describing new techniques for the study of viral ecology in aquatic ecosystems, and those that address viral
discovery.

Session Title: Understanding Biogeochemistry and Molecular Microbial Ecology across Oxic-Anoxic Interfaces of OxygenDepleted Pelagic Ecosystems
Session Description: Expansion of oxygen depletion in marine waters is closely tied to climate change and human
activities. Increasing temperatures reduce O2solubility and intensify stratification, which limits deepwater ventilation,
while eutrophication contributes to deep water oxygen demand. Oxygen stratification establishes multiple chemical
gradients effectively imposing structure on activity and phylogenetic composition of biotic assemblages within microoxic, suboxic, and anoxic layers. Recent evidence suggests that expanding ocean hypoxia/anoxia accelerates fixed N
losses to the atmosphere, climate active trace gas production and ocean acidification as well as altering biogeography
and biogeochemical cycling of numerous elements. Recent research combining molecular, geochemical and process rate
approaches have provided new insights into coupled biogeochemical cycling in oxygen-deficient marine waters and
revealed general trends in global distributions of microbial key players. However, processes controlling biogeochemistry
and biological assemblages’ activity and composition are still poorly understood, thereby limiting our ability to predict
effects of oxygen deprivation on biota and major elemental cycles in future climates. The goal of this session is to
stimulate discussion among biogeochemists, molecular microbial ecologists and biological oceanographers who study
oxygen minimum zones, anoxic basins, deep hypersaline basins, fjords and eutrophied estuaries and coastal waters and
to identify unifying principles among these systems.

Session Title: Microbial enzymes in aquatic environments: environmental control, genomics and biogeochemical
functions
Session Description: Heterotrophic microorganisms process substrates by enzyme-catalyzed reactions inside and
outside the cell. Multiple environmental factors in the marine environment, e.g. temperature, inorganic nutrient
concentrations and organic matter availability, have a strong regulatory impact on the expression and activity of many
catabolic enzymes, thereby modulating fluxes and concentrations of enzymatic products. Operating at microscale,
enzymes in aquatic systems drive large-scale transformations that are central to elemental cycles and the decomposition
of organic matter. In addition to well-established methods for rate measurements, recent methodological developments
such as microscopic techniques and the quantification of single-cell activity, high-throughput assays and improved
biochemical characterization are significantly advancing our understanding of the role of aquatic microbial enzymes.
This session invites contributions that investigate any aspect of extracellular enzymes in aquatic environments, from
rivers and estuaries to the oceans and sediments. These may include (I) environmental factors that control enzyme
activities in natural communities, (II) genomics of enzyme-producing organisms or species or (III) the role of enzymes in
biogeochemical processes from microhabitats to the ecosystem scale. We aim to learn more about the wide spectrum of
enzymatic reactions driven by marine microorganisms and the complexity of their biotic and abiotic regulation in natural
aquatic systems.

Session Title: Proteomics and Lipidomics: Expanding the Macromolecular Toolbox to Understand Oceanic processes
Session Description: Analysis of proteins and lipids produced by an organism can be a direct view into adaptation
strategies used by an individual or community in response to changing environmental conditions. In addition to dynamic
cellular responses of lipids and proteins to environmental perturbations, these two classes of organic molecules can also
be preserved long after death of the organism. Thus, the analysis of proteins and lipids can either provide real-time
biological interaction evidence, or when examined in aged matrices, they can be used as tracers to reconstruct past
environments. Discovery of these analytes in a variety of locations and matrices (e.g., sediments, frustules, dissolved
organic matter fractions) emphasizes the great potential for expanding our understanding of ecosystems using
proteomic and lipidomic methodologies. We invite contributions from all studies examining the use of marine protein
and lipids to elucidate biological, geological or physical systems in the ocean. We encourage studies that integrate
multiple “omics” approaches and aim for this session to open a discussion on relationships between transcripts,
122 | P a g e
proteins, lipids, and their resulting metabolites or activities so that integration and interrogation of these analyses can
provide novel biological insight into marine systems.

Session Description: Integration of observational and manipulative techniques are increasingly allowing scientists to
study organismal interactions at a wide range of spatial and temporal scales. These approaches are revealing the
diversity of interactions that occur in natural populations including competition and predation but also facilitation. In
this session we encourage submissions focused on how microbes interact with other taxa (e.g. microbe-microbe and
microbe-metazoan). This session is intended to explore questions related to the interactions that allow organisms to
outsource specific functions or that may be altered by changing environmental conditions, for example interactional
shifts from mutualism to competition. We hope to bring together a wide range of researchers including ecologists and
biogeochemists to discuss the important role interactions play in structuring the diversity and productivity of marine
microbes and their influence on biogeochemical cycling.

field, lab, and modeling work cutting across chemistry, microbial physiology, ecology, biogeochemistry, biogeography,
and responses to global change. Presentations will highlight studies that leverage, blend, or interpret 'omics data in
novel, interdisciplinary ways to inform pressing questions in marine biogeochemistry.

Session Title: Evolving Biologically-Enabled Ocean Observing Systems: Integrating Biological Observations with
Physicochemical Measurements for Informed Ecosystem-Based Decision Making
Session Description: The role ocean observing systems play in informing conservation and management needs is rapidly
expanding with efforts to integrate biological, physical, and chemical measurements into a “whole ecosystem”
understanding of coastal and oceanic regimes. Sustained, interdisciplinary observing now spans spatial, temporal, and
trophic scales by utilizing a wide variety of platforms (e.g., moored observatories, gliders, profiling floats, satellites) and
technologies (e.g., acoustics, bio-optics, metagenomics). Technology development is rapidly advancing biological
observing capability, such as eDNA tools for assessing biodiversity, in-situ bio-optical instrumentation for measuring
planktonic assemblages, acoustic telemetry for tracking tagged animals, and passive acoustic monitoring of marine
mammal vocalizations. Expanding national and international networks contribute to the larger Global Ocean Observing
System (GOOS) and include the Marine Biodiversity Observation Network (MBON), Animal Telemetry Network (ATN) and
Ocean Tracking Network (OTN), Ocean Observatories Initiative (OOI), Ocean Networks Canada (ONC), Long-Term
Ecological Research (LTER), and other programs collecting long-term biological observations. Incorporation of living
marine resources into the ocean observing framework is a high priority, as the scientific community strives to provide a
long-term understanding of ecosystem trends to inform policy and decision making in a world faced by multiple natural
and anthropogenic stressors to our coastal and marine environments.

Initiative installations in both the Pacific and Atlantic, research-based ocean observatories are providing advanced,
comprehensive systems for studying the ocean, atmosphere, and seafloor. Most observatories include the integration of
off-the-shelf technologies and instruments, opportunities for real-time interactive investigation, mobile and fixed assets,
various numerical model over-lays, and sophisticated data interaction tools for enhanced data exploration. This session
welcomes presentations on all aspects of ocean observatory science, from historic mining of long time series, to the
latest technological innovations. Papers dealing with interdisciplinary cross-cutting science are particularly encouraged.

Session Description: This session welcomes submissions relevant to the complete life cycle of marine data stewardship,
from proposal design and data management plans, through data acquisition, evaluation, analysis, storage,
dissemination, publication and preservation. Data from oceans, lakes, coastal, and/or estuary regions, including nearsurface atmopheric data, are all appropriate. Careful stewardship of marine data is essential to meet the growing needs
to understand the ocean/lake interface and interactions of the marine-atmosphere system on multiple time scales.
Marine data are required by researchers, planners, policy makers, and other stakeholder communities, including
secondary users not involved in the original data collection. Additionally, new requirements for linking datasets to
scientific manuscripts during the publication process are highlighting the need for more comprehensive stewardship
practices. Presentations can focus on a single data stewardship topic up to overarching visions for upcoming
national/international initiatives.

Session Title: Towards a Subsurface Ocean Climate Record and Applications that Improve Understanding of Climate
Variability and Change
Session Description: This session aims to bring together scientists working on improving ocean profile datasets with
those who use these data for climate research. The intention is to promote dialogue between these communities as we
work towards a climate-quality ocean profile database to support advances in our understanding of climate variability
and change.
Historical ocean profile observations underpin a host of ocean and climate research activities, including decadal
prediction and understanding variations in Earth's energy imbalance, the water cycle and sea level. These data have
been collected with various technologies and their accuracies and biases remain poorly determined and documented.
We invite contributions on all aspects of global and regional subsurface ocean dataset development, including: data
archaeology; quality control methods; mapping procedures; and uncertainty estimates.
We also invite contributions based on use of subsurface data, such as: ocean state estimation; seasonal-to-decadal
prediction; climate monitoring; and model evaluation. Work that employs several datasets to explore structural
uncertainty is particularly welcome.
The emphasis of this session is on the “physical” ocean variables of temperature, salinity, and related quantities (such as
heat/freshwater storage, the ocean mixed layer and steric sea level). Work based on biogeochemical tracers and other
ocean variables may also be considered.

Session Title: MBON Voyage: Integrating marine biodiversity into ocean observing systems
Session Description: Living organisms comprise the engine of ocean geochemical and ecosystem processes, and support
human communities and economic activity around the world. Understanding the role of biodiversity in these processes
is a major frontier in ocean science, with implications for global climate models, carbon budgets, fishery management,
and public health. Yet the ocean observing system strategy developed over the past few decades has not adequately
incorporated biodiversity (as evidenced by the word’s absence among the >250 index terms for this meeting’s sessions).
The staggering biological diversity and complex interactions among organisms and their physical, chemical, and
geological milieu present many challenges. Overcoming them is now becoming tractable with increasing appreciation for
the value of biodiversity, advances in molecular tools, new technologies for high-resolution remote sensing, revolutions
in bioinformatics, and a growing culture of networking, collaboration, and data sharing. This session aims to provide an
overview of these recent advances, their implications for a new understanding of changing marine ecosystems and the
consequences for humanity, and the outlook for regional to global, collaborative Marine Biodiversity Observation (and
research) Networks (MBON).

Session Title: Autonomous Observations of Coupled Physical-Biogeochemical Properties and Processes in the Open
Ocean: From the Diel and Local Scales to Climate on the Global Scale
Session Description: Profiling floats, gliders, mooring and instrumented animals were initially developed to address
questions relevant to physical oceanography. Thanks to the development of miniature low-power biogeochemical
sensors, these platforms can now perform mutli-disciplinary measurements over a wide range of spatial (sub-mesoscale
to global) and temporal (hourly to inter-annual to decadal) scales, including in highly remote areas and harsh-sea
conditions. A global robotic observation system based on these networks is thus now being progressively built which will
allow reducing uncertainties in biogeochemical stocks and fluxes and detect change in underlying processes. In this
context, the present session welcome submissions on a variety of topics, which include: emerging technologic
developments in sensors and platforms; concepts and methods to address optimal observing design from local to global
scales (e.g. OSSE); integration and fusion of multiplatform data with remote sensing (altimetry, ocean color); use of data
in initialization/validation of coupled physical biogeochemical-modeling, including science and operational aspects;
fundamental science questions (e.g. phytoplankton phenology and bloom dynamics, export, respiration, nutrient
obduction, OMZs) related to coupled physical-biogeochemical processes at any scale; use of autonomous platforms
data, in particular in real-time, in support of outreach activities.

Session Description: Today’s oceanographic research is increasingly being conducted with broad and varied time series
data that often bridges several remote sensing datasets with in situinformation from autonomous sensors, ships, animal
tracking, as well as ocean model inputs. However with more instruments becoming available that allow for longer time
series and higher spatial resolution the datasets have become larger so that downloading and computing them locally is
cumbersome and unwieldy. There are also an increasing number of datasets available. Previously there was often a
128 | P a g e
single “community recognized dataset” for a parameter, for example, the “Reynolds SST” for sea surface temperature
(SST). Now there are numerous other SST datasets to choose from. Working in this emerging environment requires new
tools and services, storage and access paradigms, visualization and remote computation capabilities. Some existing web
services like OPeNDAP, ERRDAP and Live Access Server do address some of these concerns, but fall short in addressing
new challenges. In this session we seek such new or improved technologies that address these emerging challenges in
using large volume and heterogeneous oceanographic data including tools, web services, visualization capabilities, novel
storage and access methods, dataset discovery and relevance, and server and client side analysis.

Session Title: Regional and Thematic Innovation Supporting Global Sustained Ocean Observing
Session Description: Long-term, sustained ocean observations underpin discoveries in the ocean and climate systems,
allow the detection of human-induced changes in the ocean, improve ocean and climate prediction and projections on
multiple time scales, and feed real-time ocean services that allow for appropriate decisions and policies. These efforts
are increasingly contributing to scientific knowledge and policy advice on sustaining ocean health and ecosystem
services, enabling sustainable ocean development.
Regional observing systems and projects—including but not limited to the Atlantic, tropical Pacific, Southern, and Indian
Oceans—are contributing to innovation in the design, implementation, and use of a Global Ocean Observing System,
delivering new scientific results and societal benefits.
This session invites contributions from project-based and individual efforts on: • identification and refinement of
observing requirements driven by scientific and societal needs,
• ocean models and statistical methods used in Observing System Evaluation and Observing System Simulation
Experiments,
• advances in observing technology and techniques that are building readiness for large-scale sustained observation,
• innovative integration of diverse in situ and satellite observing elements, and
• new scientific results underpinned by sustained observations.

Session Title: Integrating Ocean Observing and Animal Telemetry - the US Animal Telemetry Observing Network (ATN)
Session Description: Aquatic animal telemetry is the science of elucidating the behavior of animals as they move
through the world’s oceans and freshwater systems. Detailed observations of animal movements and their aquatic
environment, have significantly improved our understanding of ecosystem function and the evolutionary constraints of
species. These data are critical for conservation, preserving biodiversity and implementing ecosystem-based
management of living resources. Animal-borne sensors have come of age and deliver high resolution physical
oceanographic data at a relatively low cost. Animals are particularly adept at finding areas of interest to oceanographers
(fronts, upwelling areas) and they provide important insights into regions of the oceans that are difficult and expensive
to monitor (e.g. Polar Regions). Animal telemetry technology is operational and the community is starting to
incorporate this capability into the Animal Telemetry Observing Network (ATN) through the US Integrated Ocean
Observing System (US IOOS). This session will explore advances in animal telemetry observations and integration with
ocean observing to meet the current challenges of understanding ecosystem function and interaction between the
environment and the distribution of species.

Session Title: Accessing the Deep Ocean From Higher Ground: New Advances in Telepresence-Enabled Research.
Session Description: In recent years high bandwidth telecommunications have been used, particularly in ocean
exploration, to bring the immediacy of discovery to the widest possible community. In parallel the size of the
oceanographic fleet - from the number of vessels in the fleet to the physical size of the newly commissioned vessels- is
decreasing. A timely question, therefore, is: How can telepresence be used, beyond outreach, to help facilitate real-time
and meaningful participation in deep ocean investigations by scientists and students from shore as well as at sea? This
would minimize the pressure on high-value science bunks at sea while simultaneously maximizing input from the wider
intellectual capacity that can be drawn upon from an infinitely larger (potential) research team on shore. This session
will draw upon perspectives from students, early career scientists and experienced participants who have worked with
telepresence across multiple recent expeditions supported through federal agencies (NSF, NOAA, NASA) and non-profit
organizations (Monterey Bay Aquarium Research Institute, Ocean Exploration Trust, Schmidt Ocean Institute). We
encourage contributions from any and all engineers, scientists, educators and social scientists who have used
telepresence or have developed ideas on how to use telepresence better to facilitate research and education in their
expert fields.

Session Title: Advances and Challenges in Computational Oceanography
Session Description: Numerical modeling plays an indispensable role in modern-day oceanographic investigations. The
number of numerical codes and approaches that is available to address oceanographic problems is ever increasing, and
so is their complexity. In particular the push towards mesoscale and submesoscale resolving resolutions brings about
new challenges in software and hardware infrastructure.
For this session we invite contributions that address any aspect of computational oceanography. Potential topics of
interest are: new codes and parameterizations; new approaches to spatial discretizations, time stepping, analysis, and
visualization; and cutting edge simulations.

Session Title: Moving the Mississippi River Delta towards Long-Term Sustainability: Opportunities and Limitations
Session Description: The Mississippi River Delta (MRD) region contributes an estimated $45 billion in revenue annually
and has a natural capital asset estimated $1.3 trillion. The existence of the economy and associated jobs are being
threatened by the rapid coastal land loss. Solutions to the problems are complicated by many challenges including
riverine sediment supply, sea level rise, and maintaining navigation safety, flood control, ecological integrity, energy
security, and socioeconomic/cultural assets. Despite a large number of research in the past, fundamental questions
remain – Do we have sufficient scientific knowledge about the MRD? What else must we know in order to develop a
sustainable solution for saving the sinking coast? How can science and policy work together to support the solution? This
session aims at bringing together the endeavors of research and practices on the Mississippi River Delta as a complex
dynamical system between the natural and human environments. We encourage submissions reporting results from
field, modeling, and synthetic studies concerning river hydrology, sediment transport, sedimentation, coastal wetlands,
energy infrastructure, population dynamics, real estate development, and policy making in the vulnerable MRD. We
132 | P a g e
especially encourage presentations that stimulate intellectual discussion and critical thinking pertinent to finding an
answer to the above questions.

Session Title: Plastic marine debris: Advances in understanding its sources, fate and impacts
Session Description: Plastic debris was first documented in the open ocean in the 1970s, but only recently has scientific
inquiry advanced to rigorously investigate the sources, distribution, behavior, fate and biological impacts of plastic in the
marine environment. Research has expanded beyond reports of floating plastic debris and entangled animals to
systematic studies asking questions ranging from the global scale of plastic inputs and fate in the environment to
biological responses from plastic exposure in a variety of marine organisms.
Global plastic production reached nearly 300 million tonnes in 2014, experiencing exponential growth since plastics
entered the consumer marketplace in the 1950s. Plastics are ubiquitous and necessary to the modern lifestyle, yet are
frequently lost to the environment with largely unanswered questions about their sources, fate and impacts. Current
research aims to answer these questions not only to advance basic science, but also to inform members of the public,
industry, NGOs and policymakers who are working to find feasible solutions.
We invite researchers to present new results that further our understanding of the size and scope of the plastic marine
pollution problem, including its impacts on all levels of the marine ecosystem and information that will advance
solutions to this pollution problem.

Session Title: The causes and consequences of the 2014-2015 anomalous warming of the NE Pacific Ocean
Session Description: The Ridiculously Resilient Ridge of high atmospheric pressure that amplified California’s drought in
the winter of 2014 also caused an extreme regional warming of the Gulf of Alaska’s upper ocean. Then in the spring of
2014 a separate regional upper ocean warming near the southern end of the California Current System (CCS) occurred
off Baja and Southern California. By July 2014, the southern warming spread north to the Gulf of the Farallones, and by
autumn, the southern and northern warm anomalies spread and merged, warming the entire NE Pacific Ocean from
Alaska to Mexico with surface temperature anomalies exceeding 3°C -- a historical record. Anomalous biological
behavior, including occurrence of plankton species with tropical affinities at the northern end of the CCS, northward and
inshore range expansions of many subtropical fishes and sea birds, and starvation and death for top predators,
confirmed this ocean “weirdness.” Key topics for this session range from the basin-scale atmospheric conditions leading
to the wide-spread warming to the consequences to ecosystem structure and fisheries. Contributions from all disciplines
that related to the physical, chemical, and/or biological aspects of the 2014-15 evolution of the NE Pacific and CCS are
encouraged.

Session Title: Advances in interdisciplinary research to understand and sustain coastal and marine ecosystems
Session Description: The complex challenges facing our oceans and coasts extend beyond the bounds of individual
disciplines. Ocean sciences are interdisciplinary by nature, and studies spanning physical oceanography,
biogeochemistry, biology, and ecology are common. However, understanding how climate change, water quality,
fishing, and conservation decisions affect coastal and marine ecosystems requires integrating natural sciences with an
understanding of how human actions influence and respond to changes in the ocean. Building the scientific base for
decisions related to resource management and sustainability requires studies that span disciplines and that focus on
interactions and feedbacks within and between human and natural systems.
134 | P a g e
This session will bring together scientists working at disciplinary interfaces to evaluate how changes in one or multiple
components of coastal and marine ecosystems affect ecosystem conditions, resource productivity, and human uses or
benefits. We are particularly interested in contributions that focus on linkages and feedbacks between physical,
ecological, and social-economic factors across multiple scales to understand complex issues facing marine ecosystems,
such as climate change, fisheries sustainability, and water quality. In addition, how scientific information is
communicated and integrated into decision-making processes shapes its use in management, governance and policy
settings, and we encourage contributions that address outreach and policy topics.

Session Title: Integrating research on the blue crab (Callinectes sapidus): interdisciplinary approaches to investigating a
widespread and commercial important marine species.
Session Description: Blue crabs (Callinectes sapidus) are important ecologically, economically and culturally on the
Atlantic and Gulf Coasts of the United States. They range, and are studied, along the Atlantic Coast from Maine into the
Caribbean and along the Gulf coast of the USA. They have been studied in multiple ways, including through genetics,
population dynamics, and toxicological studies. This session will foster collaborations between researchers that focus on
disparate topics covering blue crabs at multiple scales and locations and encourage an understanding of the species in a
broad context. We invite submissions on the ecology, genetics, physiology, toxicology, population dynamics, and
fisheries management of the blue crab. We also encourage submissions relevant to the cultural or sociological aspects of
blue crabs and their fisheries.

Session Title: High-resolution geochemical proxies of global change: progress, problems, and utility
Session Description: Knowledge of climate and environmental change throughout geological time is derived from deepsea and terrestrial records representing long time scales. While records of climate and environmental changes at long
time scales are essential, high-resolution records at seasonal, annual, and decadal scales are equally important and
under-represented in the literature. Much of what we know about past environments is based on the geochemical
signature in various proxy archives. While substantial progress continues to be made in this area, specific obstacles and
problems do exist. We encourage papers presenting geochemical records of global change, including
calibration/validation studies, in biologic or inorganic carbonates, and highly resolved (decadal resolution) sediments.
Geochemical studies highlighting recent progress, problems, or utility are especially welcome.

Session Title: El Niño Southern Oscillation (ENSO) Diversity in a Changing Climate
Session Description: ENSO events differ in amplitude, spatial pattern, and temporal evolution. These event-to-event
variations are difficult to predict and can result in markedly different global impacts. Moreover, tropical Pacific
interannual variability appears to undergo decadal/interdecadal variations, which may obscure the detection of possible
ENSO changes associated with global warming. In this session we welcome contributions that target the US CLIVAR goal
of advancing our understanding of the origin, dynamics, impacts, and predictability of all aspects of ENSO diversity in a
changing climate, using observations, theory, model simulations, as well as paleoclimate reconstructions. The unusual
evolution of the 2014-2015 El Niño is a recent example of this diversity, and studies aimed at elucidating the physical
processes underlying that event are strongly encouraged. We also welcome studies that clarify how model biases
contribute to the diversity of ENSO representation among model simulations of past, present, and future climates, as
well as research into how to reduce or otherwise cope with those biases.

Session Title: Applications of Climate Data Records for the benefit of ocean sciences, marine ecosystems, and coastal
communities
Session Description: Many dozens of Climate Data Records (CDRs) have been produced and distributed by the scientific
community over the last decade from in situ and remotely-sensed observations of the ocean, atmosphere, and
cryosphere. These CDRs are of a sufficient quality and duration to accurately describe one or more components of the
variability of Earth's climate. Submissions are encouraged that elaborate on the use of these CDRs in both basic research
and the applied sciences. Such uses include, but are not limited to, guiding new air-sea research activities, evaluation of
impacts of climate change on coastal ecosystems, the creation of new combined or derived information products, the
analysis of extreme events, informing new public policies for coastal communities, and enabling applications that realize
specific societal benefits. Contributors are encouraged to share their best practices and lessons learned from their
experiences creating, using, and sharing CDRs as well as their results based on CDRs.

Session Title: Calcification in a changing environment- do mechanisms define vulnerability?
Session Description: Ocean acidification and warming have been shown to negatively impact many calcifying organisms.
However, the underlying mechanisms behind these impacts are largely unknown, as the mechanisms of calcification are
still poorly understood. For example, it is unclear whether invertebrate larval shells originate from intracellular
precursors or how external changes in carbonate chemistry and temperature will impact initial processes of
biomineralization. Calcification is accompanied by a huge energetic cost and is often fastest during early life stages of
137 | P a g e
animals or in unicellular organisms. How the energetics of skeleton or test formation influence vulnerability to climate
change is important for understanding long term effects of climate change. Population level differences in vulnerability
are also important for understanding adaptability. With this session, we invite researchers that study calcification
mechanisms in a wide range of marine taxa. Key questions will include: (1) What do we know about the mechanisms of
calcification, particularly relating to intracellular vs. extracellular calcification? (2) How does climate change impact
calcification processes? (3) Does vulnerability to climate change correlate with mode of carbonate formation? (4) What
are the energetic costs involved in calcification at various life stages? (5) Can differences between populations help us
better understand calcification mechanisms and vulnerability?

Session Title: Climate Impacts on Marine Fish, Fisheries, and Protected Species
Session Description: We invite presentations that explore the observed or modeled response of marine fish, fisheries,
and protected species to climate variability and/or climate change. A wide-range of marine organisms will be
considered, including invertebrates, fish, reptiles, mammals, and sea birds. Climate forcing can derive from natural
variability (i.e. ENSO), anthropogenic climate change, or both. Impacts can derive from changes in physiology,
bioenergetics, abundance, distribution, habitat, community structure, reproduction, behavior, and phenology. We also
invite presentations that explore climate impacts on marine fisheries in terms of spatial distribution, changing target
species and/or gear type, or simply the challenges faced by fisheries management in a changing climate. Studies can be
based on the dynamics of marine ecosystems and food webs, populations, or individual species. We also encourage
presentations that focus on fish, fisheries, and protected species management strategies (i.e. stock assessments, marine
spatial planning) that incorporate climate information.

Session Title: The Southern Ocean and Its Role in the Climate System: Observations, State Estimation and Modeling of
Physical and Biogeochemical Processes
Session Description: The Southern Ocean, south of 30°S, occupies just under one-third of the surface ocean area, yet it
accounts for a disproportionate share of the vertical exchange of heat, carbon and nutrients between the deep ocean,
the surface ocean and the atmosphere. The Southern Ocean is, therefore, a key player in the climate system:
understanding the physical and biogeochemical processes that determine the Southern Ocean’s mean state, variability,
and response to external forcing is critical to our understanding of the climate system as a whole, and for reducing
uncertainties in climate projections. Recent advances in data collection, state estimation and modeling capabilities have
finally established the necessary infrastructure to permit a deeper understanding of the Southern Ocean’s role in
climate. Working toward this goal, this session will present new results based on modeling and/or observational efforts
that investigate all climate-relevant aspects of the Southern Ocean, including biogeochemical processes, large-scale and
mesoscale circulation, mixing, as well as ocean-atmosphere and ocean-ice interactions.

Session Title: Ocean heat and carbon uptake and storage: observations, mechanisms and feedbacks
Session Description: Heat and CO2 exchange between the atmosphere and ocean is a major control on Earth’s climate.
Climbing atmospheric CO2concentrations, along with associated radiative impacts, perturbs the ocean state and
circulation. These physical changes in the ocean generally feedback positively on atmospheric CO2 levels by reducing
ocean carbon uptake. However, the uptake of heat alters the circulation in ways that may feedback negatively (i.e. a
stabilizing feedback) or positively on atmospheric warming trends. The sign and strength of these feedbacks depends on
139 | P a g e
the complex interplay between physical and biogeochemical processes in the ocean and their interaction with
atmospheric dynamics and radiative feedbacks. Recent advances in observational and modeling capabilities have
deepened our understanding of these relevant processes. However the exact mechanisms governing the magnitude and
regional distribution of heat and carbon uptake and storage remain poorly understood. This session seeks new and
evolving insights into modeling and observational efforts that investigate all aspects of the ocean’s role in anthropogenic
CO2 and heat uptake, storage and transport including the role of large-scale overturning circulation, water mass
formation, ocean-ice-atmosphere, mixing, mesoscale and biogeochemical processes. We invite contributions that
investigate ocean heat and carbon uptake, storage and transport on regional to global scales.

Session Title: Representation of Physical Processes in Global Climate Models
Session Description: Advancing theoretical understanding of physical processes using process studies and observations
to improve the representation of such (usually unresolved) physics in models is one of the research priorities of US
CLIVAR and the broader international modeling community. These improvements may be achieved by advances in
parameterizations or by explicit representation of the processes via, e.g., increased resolution. Pathways for improved
model parameterizations are rarely obvious, but the key steps include identification of poorly represented physics;
improving our understanding; and improving or inclusion of their representations in the models. The final step involves
an evaluation of their impacts on the model simulations, considering, for example, bias reductions and improved
forecast skills. The success of this development effort requires close collaborations among observationalists,
theoreticians, process modelers, and climate model developers.
This session is intended to facilitate such progress by bringing together needed specialists to discuss recent advances in
our understanding of missing or inadequately represented physics in models to improve or include their representations
in climate models. In addition to observational, theoretical, and process and climate model studies, submissions
addressing interactions and exchanges between different components are particularly encouraged (e.g., air-sea/iceocean/land-ocean interactions), as are advances facilitating scale-aware parameterizations of subgrid-scale processes.

Session Title: Contemporary evidence of climate change effects on lake and estuarine ecosystems
Session Description: Climate change may profoundly affect the dynamics of lakes and estuaries, by altering water
inputs, evapotranspiration, nutrient cycling, sediment load, water temperature and a myriad of other physical, chemical
and biological drivers. Climate change often is viewed in the context of future effects, yet lakes and estuaries already
display changes caused by global warming relative to past conditions. This session will highlight these fundamentally
important changes with case studies, space-for-time substitution analyses and global data analyses, as a way to gain a
better understanding of the future trajectories of lake and estuary ecosystems.

Session Title: US CLIVAR Session on Oceanic Heat Uptake, Earth's Energy Imbalance, and the Global Warming 'Hiatus'
Session Description: Through its enormous heat capacity, the ocean plays a leading role in storing transient energy
imbalances in the climate system – both forced and as a result of natural variability.. The recent debate on the so-called
global warming 'hiatus' highlights the need for improving our understanding of mechanisms that control radiative
imbalances at the top of atmosphere and in the magnitude (and uncertainty) of implied oceanic heat uptake, together
with its spatio-temporal distribution, on interannual to decadal time scales. Such understanding is also a prerequisite for
developing skillful decadal prediction. This session solicits contributions dealing with critical assessment of the
uncertainties in Earth radiative imbalance estimates; estimates of ocean atmosphere heat exchange; mechanisms of
ocean heat content (OHC) variability inferred from observations and/or models; context of the recent 'hiatus' period
within climate variability over the last century; gaps in the current global ocean observing systems and implied
141 | P a g e
uncertainties in recent OHC change estimates; estimates of radiative forcing variability over the last decades; and
observational and data assimilation requirements for improving OHC estimates.

Session Title: Assessing the Cumulative Effects of Complex Ocean Change on Marine Biota
Session Description: Oceanic conditions are changing at an unprecedented rate due to anthropogenically-driven
changes. Life in the ocean will increasingly have to contend with a complex matrix of concurrent shifts in properties that
set their physiology and control their life histories. This matrix of change will have a combined influence on marine
biota, due to both the individual effects of altered properties such as warming, but also due to the interactions between
these properties. A further challenge to studying the cumulative effects of anthropogenic change will be the
identification of the interactions of local, regional and global scales of such change. We invite abstracts to this session
from studies which highlight how this multiplicity of factors can be addressed and will alter organismal physiology,
biogeochemical cycles and/or food-webs. Theoretical, experimental and modelling approaches are welcome.

Session Title: Southern Ocean Decadal to Centennial Climate Variability and Global Teleconnections
Session Description: The Southern Ocean (SO) plays an important role in the global climate system as it connects the
major ocean basins and is the origin of bottom water, which is an integral part of the global overturning circulation. Due
to its circulation patterns, the SO is responsible for much of the anthropogenic carbon and heat absorbed by the global
ocean, and for the nutrient supply to critical oceanic biological production zones north of 30°S.
The goal of this session is a clearer understanding of the causes and consequences of decadal to centennial variability in
the SO, with a focus on (i) identifying the modes of SO variability and their underlying mechanisms, and (ii) determining
how SO variability can, in turn, influence atmospheric and (physical or biogeochemical) oceanic conditions elsewhere on
the planet. We particularly invite studies that deal with propagation pathways of anomalies originating from the SO, and
identify regions that are most affected by SO natural variability. The potential role of the SO and related teleconnections
in explaining global warming hiatus decades is also of interest. Studies from both the modeling and observational
community looking at these phenomena during past and present times and under climate warming scenarios are
welcome.

Session Title: Predicting the ecological effects of multiple environmental changes: insight through the lens of existing
natural gradients and proxy records
Session Description: Sharp increases in atmospheric CO2 are causing ocean warming, acidification and deoxygenation,
as well as changes to patterns of primary productivity and consequently food supply to marine organisms. Rates of
change are unprecedented, raising questions about whether (and how) species will adapt, communities will change, and
if these responses will reflect synergistic interactions among multiple stressors. The potential impact of multiple
environmental stressors can be examined through: 1) laboratory experiments, 2) studies of ecological dynamics along
natural environmental gradients, and 3) examinations of changes in the fossil and/or sedimentary geochemical record.
The latter two offer the advantage of illuminating responses over a complete range of variable space for multiple
stressors and often account for adaptive plasticity arising from the evolutionary history of organisms; both of which are
143 | P a g e
significantly less tractable in laboratory experiments. Thus, this session invites submissions that offer insight into future
ecological responses to global change through examination of species and ecosystems dynamics along natural
environmental gradients (e.g. CO2 vents, oxygen minimum zones, latitudinal, estuaries) and among environmental
perturbations in the fossil record.

Session Title: Implications of Global Climate Change on the Health of Coral Reef Ecosystems
Session Description: Coral reefs are some of the most diverse and valuable ecosystems in the world. Vital for
maintaining ecological balance in coastal tropical environments, they also stand as the foundation for enormous cultural
and economic resources. However, the increasing threat of global climate change and the continued degradation of
coral reefs around the world is an alarming call for action towards the identification of implications of temperature
stress and subsequent rehabilitation of these vital marine environments. Recent bleaching events throughout the Pacific
Ocean and subsequent coral reef studies lend greater insight into how these ecosystems cope with warming oceans and
what shifts in ecosystem structure can be expected. In this session, focus will be dedicated towards elucidating shifts in
coral reef ecology, changes in molecular biomarkers of stress, zooxanthellae clade variation, and physiological and
molecular changes during heat stress, which will allow for greater insight into anticipating and addressing coral reef
environmental changes.

Session Title: Climate Trends, Hydrographic Variability, Circulation and Air-Land-Sea Interactions in the Marginal Seas of
the North Atlantic.
Session Description: The regional scope of the session includes North Atlantic seas (e.g., Labrador Sea, Irminger Sea,
Iceland Basin) and semi-enclosed basins (e.g., Gulf of Main, Gulf of Saint Laurence, Newfoundland Basin, Hudson Bay,
Baffin Bay), each showing strong annual, interannual and multidecadal variability and interacting with open ocean. The
processes responsible for these changes and interactions may have atmospheric (e.g., varying cumulative heat losses
driving winter convection in the Labrador Sea), terrestrial (e.g., varying fluvial and glacial discharge) and oceanic (e.g.,
advection of heat and salt, sea level rise) origin or nature. In turn, the forcing mechanism may be triggered by natural
variability or anthropogenic factors. Each region, subregion or layer may show some characteristics of changes found
elsewhere or act differently, including acceleration of dominant trends if not shifts between modal states. The session
will present an opportunity to relate these findings and identify key points, processes and scales associated with the
largest signals which are likely to influence many aspects of societal life. Interdisciplinary presentations, syntheses of
existing sources of oceanographic information including, but not limited to, vessel and profiling float observations,
moored and remote sensing data, comparisons of model simulations and observations are cordially invited.

Session Title: Mesoscale eddies and processes: dynamics, transport characteristics, and biological impacts
Session Description: Oceanic mesoscale features such as eddies, fronts, jets, and striations represent a large fraction of
oceanic kinetic energy and contribute significantly to the horizontal and vertical transports of momentum, heat, salt,
nutrients, plankton, and even plastic! The extent to which eddies are coherent structures that can act as material
transport agents, carrying their contents over large distances and across ocean basins, is a topic of great interest.
145 | P a g e
Mesoscale features often interact with large-scale ocean circulation, mixed layer, mode water formation, coastal
upwelling, and atmosphere as well as with Rossby and inertia-gravity waves. Yet their life cycles, three-dimensional
structure, and transport characteristics, as well as their dynamics remain poorly understood. The recent expansion of insitu observations, eddy-resolving numerical models, and ecosystem models provides, in combination with satellite
observations, data assimilation, and theory, a great opportunity to advance our understanding of mesoscale
phenomena. This session invites reports on observational, theoretical, experimental, and modeling studies of the
dynamics of ocean mesoscale processes, as well as their direct impacts on marine ecosystems. Studies of the
interactions of oceanic mesoscale phenomena with smaller or larger scales, biogeochemical processes, coastal seas, and
the atmosphere are also welcome.

Session Title: Atlantic Meridional Overturning Circulation: Past, Present, and Future
Session Description: The Atlantic Meridional Overturning Circulation (AMOC) comprises warm upper waters flowing
northward, becoming colder and denser until they form deep water in the Nordic and Labrador Seas that then returns
southward through the North and South Atlantic. The AMOC transports a substantial amount of heat from the tropics
and Southern Hemisphere toward the North Atlantic, where the heat is then transferred to the atmosphere.
Consequently, changes in the AMOC could have a profound impact on many aspects of the global climate system.
Climate models in unforced control integrations, simulate a rich spectrum of internal AMOC variability on seasonal,
through decadal and multidecadal, to multicentennial timescales. The AMOC is also thought to be externally driven, e.g.
by solar variability and changing volcanic activity. Anthropogenic climate change may also impact the AMOC, and most
climate models project a significant slowing by the end of the century.
We invite contributions on the AMOC of the past millennium, studies that describe the present state of the AMOC
including its dynamics, mechanisms of property transport, short-term temporal and spatial variability, and work
addressing the future evolution of the AMOC. Observational (proxy and instrumental) as well as modelling studies are
welcome.

Session Title: Observing and predicting historic and future surface and internal tides
Session Description: The gravitational pull of the sun and the moon causes predictable but fascinating surface tidal
motions in the world’s oceans. These motions may become resonant in shallow coastal seas and affect commerce and
the exchange of matter at the land-ocean interface. Throughout the ages changing sea levels and stratification have
influenced the predictability of the surface tides, and the tides of the past and future are different than today. As the
surface tides propagate over under water topography in a stratified ocean, tidal internal waves are generated. Although
these internal tides are seen propagating for 1000s of kms, their fate is still unknown. Along the way the internal tides
may scatter off underwater topography and interact with the mesoscale circulation, greatly affecting their predictability.
Hence, these incoherent internal tides may alias with mesoscale-submesoscale circulation in altimetric satellite
observations. In this session, we encourage submission of talks on observations of surface and internal tides, on regional
and global modeling of surface and internal tides, and on how tidal predictive capabilities can be improved in models.

Session Title: Observations and Modeling Studies on the Physical, Bio-physical and Bio-geochemical Processes and Airsea Interactions of the Indian Ocean
Session Description: This session emphasizes recent studies on physical, bio-physical and bio-geochemical processes and
air-sea interactions in the Indian Ocean. Scales of interest range from submesoscale and diurnal to intraseasonal and
interannual variability of ocean circulation, upwelling, boundary layer dynamics, upper ocean mixing processes, the heat
and salt budget, water mass exchanges and transports, monsoon variability, and the impact on the oceanic biosphere of
those processes. Studies that link the regional oceanography to global scales such as the IOD, MJO and ENSO will also be
included. Analyses of observations based on remote sensing, in situ measurements, gliders, Argo floats and drifters are
particularly encouraged as well as theoretical and modeling works. This session is one of the foci of IIOE-2 campaign and
also we encourage papers from field campaigns from Air-Sea Interactions in the Northern Indian Ocean – Regional
Initiative (ASIRI), Northern Arabian Sea Circulation- autonomous Research (NASCar), and Dynamics of the MJO
(DYNAMO).

Session Title: Ocean salinity and water cycle variability and change
Session Description: The session highlights research investigating observed and modeled ocean variability and change,
and focuses on ocean salinity, an important driver of ocean circulation and a key indicator of the global water cycle. New
salinity observations are extending the scope of ocean and climate research. The SMOS and AQUARIUS/SAC-D satellite
missions present an unprecedented opportunity to monitor surface salinity and study its relation to ocean circulation
and the water cycle. Satellites are complementing in-situ observations and process-oriented field experiments (e.g.,
SPURS) that are allowing researchers to develop a detailed understanding of the causes and consequences of salinity
variations. Recent observations, along with historical measurements and model simulations, are revolutionizing the view
of the ocean on short (daily to seasonal) and longer (climate, >30-year) timescales.

Session Title: Ocean Circulation Variability in the Tropical Western Pacific and Eastern Indian Oceans
Session Description: Surrounding the inter-basin warm pool, air-sea interaction and
time-varying ocean circulations in the tropical western Pacific, eastern
Indian Ocean and marginal seas are critically important for regional and
global climate variability. This session seeks contributions with topics
including oceanic circulation variability in the tropical western
Pacific and eastern Indian Oceans, interactions with the extra-tropics,
low-latitude western boundary currents, the Indonesian Throughflow, and
upper ocean processes and air-sea interactions associated with the warm
pool and Asia monsoon. The session will cover signals of all timescales
from diurnal, intra-seasonal, inter-annual to decadal. This session
intends to provide a forum for coordinating observational (such as
TPOS2020 and IIOE2) and modeling efforts relating to climate variations
in the tropical western Pacific and eastern Indian Oceans.

Session Title: Variability and Predictability of Ocean Circulation and Climate in the Indo-Pacific Ocean
Session Description: The tropical Indian and Pacific Oceans are the areas where the warm pool and the strong equatorial
ocean currents dominate. The variability of the ocean in this part of the globe is of great importance to the global
climate variability and predictability. Among them, ENSO and Indian Ocean Dipole (IOD) are the strongest interannual
climate modes that interact over and through the Indonesian seas. Under global warming, the ENSO and IOD are subject
to long term variations, which are believed to be controlled by the tropical and extra-tropical exchange. A number of
field experiments have been designed and implemented to understand the dynamics of the processes that give rise to
the variability and predictability of the Indo-Pacific ocean circulation and climate. In this session, studies about the
ocean circulation and the warm pool in the Indo-Pacific Ocean, its effects on the variability and predictability of ENSO
and IOD, tropical-subtropical-Southern-Ocean interactions and exchange and their climatic effects, etc., are in scope.
Authors are encouraged to submit abstracts for discussions and information exchange. In addition, contributions are
also encouraged about the impact of the Indo-Pacific oceans and their climate variability on the variability and
predictability of monsoon and typhoon and their feedback.

Session Title: Advances in Coastal Ocean Modeling, Observations, and Prediction
Session Description: Downscaling and extending predictability in coastal and shelf seas are two of the objectives of the
GODAE OceanView (GOV) initiative through its Coastal Ocean and Shelf Seas Task Team (COSS-TT). Broad participation
and international coordination of interdisciplinary coastal and shelf models nested in data assimilative large scale
models are COSS-TT priorities. This session will provide a forum for multi-scale hydrodynamic modeling and integrated
observational studies that aim toward scientific validation, prediction and operational applications of numerical models
in coastal and shelf seas, leading to new understanding of multiscale nonlinear ocean processes. Applications of nested
models, such as the influence of physical processes on ecosystem dynamics and interdisciplinary coastal simulations and
predictions are also welcome. The session will promote the discussion of methodologies that lead to reliable coastal
forecasts and applications (such as data assimilation, probabilistic approaches, influence of nesting, currents-waves and
atmosphere-ocean interactions), Observing System Simulation Experiments and the impact of sustainable, integrated
modeling and observational networks that connect local, regional and global scales.

Session Title: Lagrangian Perspectives on Ocean Circulation and Mixing
Session Description: Advances in Lagrangian and semi-Lagrangian instrumentation have made it easier to sample the
ocean in two and three dimensions, and at scales down to a meter or less. Analyses of the trajectories obtained from
these instruments is leading to a deeper understanding of dispersion, turbulent and chaotic mixing, and coherent
features. At the same time, advances in dynamical systems theory have made it possible to map out coherent
Lagrangian structures, such as material boundaries of eddies, in ocean models, and to perform direct assimilation of
Lagrangian trajectories into models, all in the presence of complex time dependence. This session will bring together,
and stimulate a lively discussion among, investigators from the various communities (instrument design, field programs,
applied mathematics, and data assimilation) that have supported progress in these areas.

Session Title: Evaluation, Design, and Optimization of Observing Systems using the Observing System Simulation
Experiments framework
Session Description: Given the expense of deploying and maintaining ocean observing systems, a pressing need exists to
optimize regional-to-global operational observing systems, and also to design short-term regional observing programs to
151 | P a g e
improve ocean forecasts for specific applications. Observing System Experiments (OSEs) and Observing System
Simulation Experiments (OSSEs) are powerful tools for quantifying the impact of specific observing systems on ocean
analyses and forecasts, and for optimizing their deployment. OSEs are used to evaluate existing observing systems, while
OSSEs are used to assess the impact of new observing systems or to quantify alternate deployment strategies toward
the optimization of existing systems. Presentations are solicited that use these advanced techniques to evaluate existing
and planned ocean observing systems with applications to a broad range of oceanographic problems that include:
improving regional-to-global ocean analyses and forecast products and monitoring ocean climate variability. Papers are
welcome that present alternative methods in observing system design and impact assessments, such as information
matrix analysis and adjoint-based procedures.

Session Title: Circulation, biogeochemistry, and ecosystem of the western North Pacific marginal seas
Session Description: The western North Pacific consists of series of marginal seas from the Okhotsk Sea, Japan/East Sea,
and East and South China Seas. The circulation, biogeochemistry, and ecosystem of these seas are known to vary on a
wide range of temporal and spatial scales, as they interact with the western boundary currents, monsoonal winds, and
land. There have been considerable advances in exploring these seas, with some successfully establishing a solid
framework for developing a detailed implementation plan for integrated multi-national time-series observations and
accompanying process research. This is a good time to share the knowledge and experience/lessons learned in
dynamics, biogeochemistry, and ecosystem variability, and discuss the future directions. The session seeks contributions
from studies including, but not limited to, frontal mixing, ventilation and overturning circulation, strait-exchange flows,
biogeochemistry cycles, and pelagic ecosystem and its underlying dynamics.

Session Title: Observing and Modeling the Meridional Overturning Circulation in the South Atlantic: Causes of variability
and impacts on climate, weather, and ecosystems
Session Description: The meridional overturning circulation (MOC) in the Atlantic is a key element of the time-variable
coupled climate system and may have played a significant role in the subsurface sequestration of heat during the recent
global warming hiatus. The South Atlantic Ocean is unique in its role as a nexus and melting pot for water masses
formed elsewhere and transiting between the far regions of the World Ocean. In the past decade, the South Atlantic
MOC observing system has expanded to include moored arrays and intense hydrographic surveys, providing tantalizing
glimpses of the variability introduced to the MOC. Here, we invite contributions of recent studies quantifying and
analyzing South Atlantic MOC (SAMOC) variability over time scales ranging from intra-seasonal to decadal using recently
collected in situ observations, remotely sensed data, theory, and numerical modeling. This includes, but is not limited to:
an exploration of the local and remote SAMOC forcing mechanisms, analysis of how SAMOC variations relate to interocean exchanges and storage of heat, salt, and nutrients, and an evaluation of the impacts of SAMOC on regional and
global climate, extreme weather, and/or marine ecosystems.

Session Title: The Ocean's Energy Cascade: Measuring and Modeling of Instabilities, Internal Waves, and Turbulence
153 | P a g e
Session Description: Large scale O(105 m) oceanic motions are linked to the turbulent scales O(<1 m) through a variety
of mechanisms including internal wave radiation, interaction, and scattering, frontal instabilities, and boundary layer
physics. Such mechanisms are essential for the vertical redistribution of energy generated along the ocean’s upper and
bottom boundaries and thus are of critical importance in providing mechanical energy to processes in the stratified
interior of the ocean. Regions of enhanced mixing are often found where a combination of currents, stratification, and
topography act together to increase the potential for nonlinear interactions in the flow, for example through frontal
instabilities and strong internal wave generation. Enhanced turbulence leads to mixing of water mass properties and
changes to flow dynamics that can feedback on the larger-scale physics. This session welcomes contributions from
observational, theoretical, and numerical studies of the ocean's energy cascade at small scales (i.e. submesoscale and
smaller).

Session Title: Boundary Currents and Their Interactions with the Continental Shelf Ocean
Session Description: On many continental shelves, the proximity of energetic boundary currents in deep water at the
shelf edge is a key dynamic in mediating shelf-sea/open-ocean exchange, and this remote forcing can match or exceed
local drivers of coastal circulation. Boundary current transports themselves are of leading importance in basin-scale
budgets, but their observation is challenging where shelf-edge flow-bathymetry interactions foster variability at short
length and time scales. The provision of three-dimensional and time-varying ocean circulation estimates in boundary
current regimes, resolving scales of a few kilometers, are improving through the synthesis of coastal observatory data
and advances in data-assimilative modeling.
This session invites contributions on shelf/coastal/boundary current observing and modeling, specifically, but not limited
to; the impacts and influences of large-scale remotely driven variability on boundary currents; how variability of the
strength and dynamics of the dominant boundary currents drive shelf-sea/open-ocean exchange, including nutrient
forcing, carbon export, and other aspects of productivity of shelf waters; the design of integrated coastal/boundary
current observing systems; the response of coastal and boundary current dynamics to local and regional wind and
buoyancy forcing fields; and, the impact through teleconnections that boundary current processes have on dynamics
and climate variability at larger scales.

Session Title: Internal wave driven mixing and its role in the climate system
Session Description: Mixing in the stratified ocean interior is observed to be variable in both space and time, and is
largely set by the geography of internal wave generation, propagation, and dissipation. The processes leading to mixing
include dissipation of wind- and tidally-generated internal waves occurring in the near- and far-field, as well as breaking
internal lee waves. Theoreticians and modelers have recently been developing more physically-based parameterizations
of the sub-grid-scale processes related to internal wave-driven mixing for implementation in climate models. Climate
models indicate a sensitivity of the large scale circulation and climate to both the magnitude and distribution of the
parameterized mixing. This session will bring together theoreticians, modelers and observationalists to share recent
progress in the development and implementation of relevant mixing parameterizations in global climate models,
including in paleo-climate scenarios, as well as relevant observations of processes to be incorporated into these models.
This session will act as a forum to update the larger oceanographic community on the latest observations and model
implementations, providing an evaluation of climate model representations of internal wave driven processes, as well as
an assessment of areas where continued observational and modeling effort is required.

Session Title: Ice-ocean interactions and circulation around the Antarctic margins
Session Description: Processes occurring at or close to the ice-ocean interface around Antarctica influence the state and
circulation of a large proportion of the global ocean. Over 1/3 of the global sub-surface ocean is filled and ventilated by
Antarctic Bottom Water, largely sourced from the Weddell and Ross Seas. Sea ice exported from coastal polynyas
freshens surface waters further north, contributing to the formation of Antarctic Intermediate Water. Inflow of warm
Circumpolar Deep Water beneath floating shelves of marine-terminating glaciers promotes retreat of the grounded
portion of the ice sheet, and thus sea level rise. Yet our understanding of these processes has historically been limited by
the prohibitive costs of in situ observations and high-resolution models. This session will showcase recent advances in
understanding the physical processes occurring in the Antarctic marginal seas, across the Antarctic continental shelf and
slope, and within the ocean cavities beneath floating ice shelves. Studies based on observations, numerical models and
theory are all welcome. The conveners particularly encourage submissions addressing mechanisms that facilitate water
mass exchanges across the Antarctic continental slope, the role of short-timescale flows like mesoscale eddies, tides,
and dense water overflows, and processes occurring at the interface between the ocean and sea/shelf ice.

Session Title: Is it “roughness” or “bathymetry”? Resolving the Often Unresolved Interactions Between Time-varying
Flow and Topography
Session Description: Topography in the ocean varies continuously over a wide range of length scales, from those
typically considered “roughness” to those considered “bathymetry”. Flow is also driven over topography at a range of
time scales, by processes such as surface and internal waves, tides, mesoscale motions, and steady currents. Interaction
of flow with topography causes persistent spatial patterns in pressure, currents, and turbulence. In ocean circulation
models where the domain is discretized into a finite resolution grid, some of these processes are resolved and others are
not. Spatial averaging gives rise to additional terms in the momentum balance (e. g., drag and dispersion) that are not
included explicitly in many observational efforts, theoretical analyses, and modeling studies. The goal of this session is to
bring together the growing number of people who are investigating flow topography interactions at a range of spatial
and temporal scales. Field observations, laboratory measurements, numerical modeling, and theoretical studies that
contribute to understanding this problem are all encouraged. We hope to inspire discussion about the physics of
156 | P a g e
interactions between time-varying flow and topography, the limitations of existing parameterizations, and how these
processes can be better represented.

Session Title: Mesoscale processes in the ocean and their representation in earth system mode
Session Description: Mesoscale eddies regulate momentum and tracer budgets in the ocean, playing a primary
role in the circulation and biogeochemical cycle of the ocean and the climate of the Earth system.
However, eddy dynamics, three-dimensional structure, sources, and life cycle, are not fully
understood and remain poorly represented in general circulation models.
Parameterization schemes are commonly used to approximate their
effects on physical and biogeochemical components of ocean models, but
the sensitivity of regional and global scale dynamics to
different parameterizations and spatial resolutions remains unclear. This
session invites reports on observational, modeling, and theoretical
studies of the dynamics of mesoscale eddies, Rossby waves,
fronts, jets and eddy-mean flow interactions, among other subjects related to ocean mesoscale eddies.
We also encourage discussion of rectified effects and potential feedbacks between
ocean processes pertaining eddies and other earth system components (e.g.,
between ocean physical and biological processes), representation of
these feedbacks in general circulation models, and examination of
model sensitivity to changing resolution and different parameterizations. This session aims
to elucidate the effects of improved representation of mesoscale eddy process
on the physical and biogeochemical climate in earth system models and to explore hypotheses concerning
the dynamical response to projected changes in climate in the future.

studies on the physics and chemistry of the deep Gulf, beyond the shelf break. This session focuses on these studies, and
how they are changing our views of the processes that occur there. We encourage submissions that cover in situ
measurements and models of the deep Gulf, from the surface to the ocean floor.

Session Title: North meets South: an integrated perspective of high latitude ocean dynamics
Session Description: The ocean dynamics at high northern and southern latitudes exhibit a rich range of behavior that
differ substantially from those at lower latitudes. For example, the classical subtropical Sverdup solution does not
provide a lowest-order description of the wind-driven circulation at high latitudes. The large-scale flow instead appears
jet-like, often associated with mixing barriers, as in the Antarctic Circumpolar Current (ACC) and in topographicallyguided boundary currents. Mesoscale eddies emerge as key agents in fluxing tracers, momentum, and vorticity across
such jets. Topographic control, the possible presence of sea ice or ice shelves, and extremes of strong and weak
stratification, are all characteristics found both in the high north and high south. Yet important differences exist: for
example, high-latitude northern hemisphere boundary currents typically flow in the same direction as
planetary/topographic Rossby wave phase propagation, while the ACC flows in the opposite direction. We invite
observationalists, modelers, and theoreticians to submit talks and posters that focus on the dynamics of the large-scale
and mesoscale dynamics of high latitudes. The aim is to bring together scientists with expertise from south and from
north to discuss both similarities and differences between the two hemispheres.

Session Title: Variability and connections of ocean boundary current systems in the Indo-Pacific Ocean and their climatic
and environmental impacts
Session Description: Variability of the West Pacific-East Indian warm pool plays a vital role in the occurrences of ENSO
events and in the genesis of climate disasters. Strong Ocean Boundary Currents (OBCs) systems, including the tropical
Pacific western boundary currents (WBCs) and Indian eastern boundary currents (EBCs), and the Indonesia Throughflow
(ITF) in between, play a key role in the heat, mass and freshwater budgets of the warm pool where marine bio-diversity
and sediments convergent. The OBCs are also the main route for extra-tropical decadal variability to influence the
tropical region, and their variability is important for understanding the ENSO and its decadal modulation. Taking
advantage of the substantive investment over the past decade, the understandings of the Pacific WBCs, the Indian EBCs,
and the ITF, as well as their effects on the warm pool and ENSO dynamics have been much improved. This session will
offer a forum to bring together fundamental and multi-disciplinary advances in our knowledge of variability and
connections of OBC systems in the Indo-Pacific Ocean and their collective impacts on climate and environment
variability. The session will also seek the coordination in the observations to ensure that the sum is greater than the
total of these individual efforts.

Session Title: Interaction between internal waves and mesoscale processes
Session Description: Internal waves and mesoscale processes are common phenomena in continental shelf and also in
general ocean. Since internal waves and mesoscale processes have different temporal and spatial scales, they were
usually studied separately. However, recent experiments reveal interactions between them. For instance, along the west
boundary of the North Pacific Ocean, interaction between tides and abrupt topography generates strong internal waves.
Meanwhile, the Kuroshio flows along the west boundary and mesoscale eddies arrive from the central Pacific Ocean.
The Kuroshio and mesoscale eddies change local stratification and induce additional flow, which affect the internal wave
generation and propagation. On the other hand, when the internal waves propagate across the Kuroshio and mesoscale
eddies, internal wave breaking or scattering provides energy for local mixing, hence influencing the evolution and
dissipation of the Kuroshio and mesoscale eddies. In this session, contributors are encouraged to present recent
progresses on the interaction between internal waves and mesoscale motions, including remote sensing and in situ
measured evidences, as well as newly development in theories and numerical models. This session will not limit only to
the west boundary of the Pacific Ocean. Studies in other regions, as well as general solutions, are all welcome.

Session Title: Developments and Ocean Applications of Data Assimilation, Uncertainty and Sensitivity Analyses
Session Description: Data assimilation and uncertainty and sensitivity analyses are vital components in the production of
ocean science reanalyses for the study of various ocean processes. They are also used in model calibration (including
parameter estimation), design of observation systems, and for operational forecasts and analyses. The challenges in this
area are numerous due to the non-linear interaction of multiple spatio-temporal scales as well as uncertainties due to
the resolution of physical processes, parameterizations, and uncertain inputs. The goal of this session is to bring
together researchers working in the areas of ocean data assimilation, model sensitivity analysis, and uncertainty
quantification, with the goal of discussing new technical developments and recent applications. Contributions
concerning the following issues are particularly of interest:
New developments and original applications of data assimilation, uncertainty and sensitivity analyses methods
Coupled data assimilation, including ocean-atmosphere and ocean-biogeochemical systems
Estimation and uncertainty quantification of ocean models parameters, inputs, and outputs
Developments of advanced ocean operational and reanalysis systems

Session Title: Satellite-data based studies of heat and freshwater budgets and the air-sea interface: From diurnal to
decadal timescales
Session Description: The continuous record of satellite data over the last 30 years has allowed fundamental advances in
our understanding of processes that control the heat and freshwater budgets of the ocean and their variability over a
broad range of timescales. Satellite altimetry measurements of sea level, microwave based measurements of sea
surface temperature, scatterometer winds, gravity measurements that give us the mass distribution, and new
measurements of sea surface salinity have all contributed to this understanding. This session will bring together
scientists who work to synthesize satellite data along with in situ observations and models to improve our
understanding of the controls of the ocean heat and fresh water budgets and the ocean interaction with the atmosphere
on diurnal to decadal time-scales. We especially encourage submissions that focus on the way in which oceanic
processes control the exchange with and impacts on the atmosphere. We also encourage submissions that link to the
career of Dr. Kathryn Kelly on her retirement. She is a pioneer in the use of satellite data to understand not only the
surface of the ocean, but also large-scale processes at work in the ocean from the surface to the thermocline and their
interactions with the atmosphere.

Session Title: Quantifying and Applying Operational Oceanography Forecast Skill
Session Description: We welcome contributions in the area of Operational Oceanography with an
emphasis on quantifying forecast skill or uncertainty and translating
forecasts into operational guidance or risk assessment. Operational
oceanography encompasses the steps necessary to formulate quantifiably
accurate representation or probabilistic distributions of real time or future
ocean states that can inform decision-makers for supported activities. Topics
include assessment of forecast accuracy, data assimilation, ensemble or other
probabilistic forecasts, and risk assessment allowing for forecast
probabilities or uncertainty. Areas of interest include physical (waves,
currents, ice, thermohaline), biogeochemical (optical properties, chlorophyll,
bioluminescence, etc.) and acoustic properties and their downstream
applications. Submissions may encompass results from the nearshore to the open
ocean within local, regional, or global models and their complementary
observing systems. We would like to focus on risk analysis, forecast validity
and uncertainty; observational network assessment and adaptive sampling; and
reconciliation of multi-model / ensemble simulations. With the move towards
the routine dissemination of oceanographic services we also welcome
contributions reflecting the current trend in this discipline.

Session Title: New Insights on Continental Shelf and Slope Processes from the use of Autonomous Platforms
Session Description: Moving from large to small scales, a variety of energetic processes are found over continental
slopes and shelves ranging from wind-driven boundary currents; upwelling; eddies and fronts; topographically-trapped
162 | P a g e
motion; internal tides and waves; strong submesoscale flows; and turbulent mixing. Autonomous platforms including
gliders, floats, and propelled Autonomous Underwater Vehicles (AUVs), among others, are increasingly being used in the
coastal ocean to provide high-frequency, fine-scale, and extended duration measurements that offer the potential for
gaining new scientific understanding of these complex processes. Autonomous platforms also increasingly support
biogeochemical measurements that facilitate new studies into the biogeochemistry of the shelf-slope waters and the
impacts of physical processes on biogeochemistry. This session welcomes all submissions that exploit the new potential
offered by autonomous platform data collection, either alone or in combination with other data types and/or with
numerical modeling, in order to gain new understanding into physical or biogeochemical shelf-slope processes.

inland, or marginal seas and large lakes (depths less than 1000 m). Research pertaining to numerical modeling,
experimental, and laboratory studies of physical processes such as circulation, ice dynamics, waves, turbulence,
stratification, storm surge, and sediment dynamics are solicited. Studies should focus on large water bodies where the
Earth’s rotational effects are important, such as the Gulf of Mexico, Adriatic Sea, Persian Gulf, Bering Sea, China Seas,
Baltic Sea, Caspian Sea, the Great Lakes, Sea of Okhotsk, or similar systems.

interface near strong currents, they contribute to numerous physical, biological, chemical, and climate processes and
constitute a means of communication between high and low latitudes. This session aims to examine recent advances in
our knowledge of these wide-ranging water masses. Abstracts are welcome that address diverse physical,
biogeochemical, and climate aspects of mode and intermediate waters: their formation and ventilation; their pathways
to lower latitudes; their impact on surface and subsurface ocean biology and chemistry; and their variability on
timescales from interannual to ice age.

Session Title: Energy Transfer Across Scales: Interactions Between Structures, Physical Processes, and Energetics
Session Description: Ocean circulation involves strong nonlinear coupling between processes and structures over a wide
range of scales, from the global down to the microstructural. Such interactions play a primary role in determining
budgets of momentum, heat, carbon, and other biogeochemical tracers in the ocean, which regulate Earth’s climate. A
promising approach to better understand dynamics at various scales, as well as their interactions, is to consider their
energetics. Yet, significant uncertainties remain in our understanding of oceanic energy pathways. This includes various
nonlinear processes and their contribution to the transfer of energy across scales, such as instabilities, eddy-mean flow
interactions, wave generation and breaking, among others. Understanding energy transfer across scales is fundamental
not only for developing a more complete description of ocean dynamics, but also for the formulation of
parameterizations in ocean climate models.
In this session we invite discussions of theoretical, observational and modeling studies addressing the above issues
pertaining to energy transfer, spanning a range of scales from global down to the submesoscale.

Session Title: Theory and applications of variational data assimilation
Session Description: Ocean models from coastal to global scales are known to be erroneous due to model numerics and
other simplifications that must be made. Data assimilation is the most widely used process through which the ocean
models can be periodically adjusted to better match reality, and thus, produce improved forecasts and/or simulations.
The advancement in computational resources (in terms of efficiency, storage, and parallel CPUs) has provided
researchers the opportunity to push the envelope in applying advanced data assimilation methodologies in realistic
and/or operational ocean forecasting settings. This session seeks proposals that focus the theory of 3-dimensional and
adjoint-based 4-dimensional variational methods, and their applications with realistic models and observations, which
take advantage of the improved computational resources now available, or the projected computational resources that
will be available in the future. Applications can include assimilation with large geographical grids, high-resolution
domains and complex flow regimes.

Session Title: Ocean Analysis and Forecasting via Probabilistic Techniques
Session Description: Probabilistic methods are becoming more widespread to improve ocean forecasting from the
coastal environment to the deep ocean. These techniques are attractive because the mean probabilistic forecast is
thought to give a better forecast than a single deterministic forecast and they also give an estimate of the uncertainty
about the mean state. Ensemble techniques are an attractive methodology for generating probabilistic ocean forecasts.
The goal of this session is to provide a forum for the presentation of ensemble modeling techniques and results. Topics
of interest include but are not limited to: Generation of ensemble perturbations; evolution and measures of ensemble
spread; use of stochastic forcing; extension to coupled modeling; applications for data assimilation; bias correction and
calibration; ensemble metrics and validation; and post-processed derived probabilistic products.

Session Title: North Atlantic warming and its impact on the Greenland Ice Sheet and Arctic glaciers
Session Description: The warming of the upper layers of the subpolar North Atlantic, over the last two decades, has
been associated with a thickening of the warm, salty layer of subtropical origin and changes in the coupled atmosphereocean circulation. The resulting heat content anomaly of the upper ocean is unprecedented over the instrumental
record (50-100 years) except, perhaps, for a similar warm period during the 1930s. These changes have spread to the
continental margins of the subpolar North Atlantic, Baffin Bay and the Nordic Seas where they have been implicated in
the widespread retreat of Greenland’s and other Arctic glaciers. The goal of this session is to bring together
contributions that document and/or seek to explain the recent changes in the subpolar North Atlantic, the Nordic Seas,
the adjacent marginal seas (including the continental margins) and their impact on Greenland and Arctic glaciers. Of
interest are studies targeting the basin-wide North Atlantic and sub-Arctic coupled atmosphere-ocean system, as well as
local atmosphere-sea ice-ocean processes that may modulate glacier-fjord-continental shelf interactions. While the
main focus is on the recent decades, reconstructions addressing the 1930s warm period are also encouraged.

Session Title: The dynamics and consequences of non-stationary tides: tidal variability from the coastline to the deep
ocean
Session Description: Astronomically-forced ocean tides are generally one of the most predictable components found in
oceanic time series, but non-stationary tides, i.e., tidal signals which are not directly predictable from astronomical
forcing, have received recent attention for their relation to long-term evolution of coastal water levels, including
extreme events, their use as diagnostics of non-tidal processes, and their role in dissipation and mixing in the ocean. This
session seeks contributions concerning tidal variability at a range of space and time scales encompassing seasonal and
interannual variability of barotropic tides and baroclinic tides in the open ocean and at the coast, as well as shorter timescale processes such as, for example, internal tide/mesoscale interactions. Both observation- and model-based studies
of the nonlinear processes leading to non-stationary tides are invited, as well as application-based studies focused on
tidal prediction. The session seeks to facilitate an exchange between researchers focussed on narrow-band tidal
dynamics and researchers of broadband phenomena, such as storm surges, to highlight new investigations and
applications in both areas.

Session Title: MOC choke points, dense overflows, and rotating hydraulics
Session Description: The dense water component of the Meridional Overturning Circulation (MOC), formed in the highlatitude oceans, undergoes significant mixing and water mass transformation at choke points such as the deep passages
of the Greenland-Scotland Ridge, Samoan Passage, and mid-ocean ridge fracture zones. These flows are characterized by
a driving internal pressure gradient, a sheared and density-stratified interface, and often significant mixing and
entrainment due to lee waves, eddies, and hydraulic jumps. The resulting diapycnal fluxes are therefore driven by the
mean flow and available potential energy, modifying the energetic requirements on tidal mixing and surface buoyancy
fluxes for closing the overturning circuit. Coriolis and potential vorticity effects are often important to varying degrees.

As these water masses have been recently ventilated and therefore contain anomalous properties relative to the
surrounding waters, studies of natural and anthropogenic tracers are highly valuable for understanding mixing rates and
residence times. This session welcomes abstracts on observational, theoretical, laboratory, and modeling studies of
processes relevant to MOC choke points (whether occurring in the deep limb of the MOC or not).

Session Title: Interactions between the open ocean and marginal/coastal seas in a changing climate
Session Description: Climate changes affect physical and biogeochemical processes in both the open ocean and
marginal/coastal seas. Observations have shown that coastal waters in some areas have experienced significant changes
in the last several decades, such as rises in water temperature, changes in coastal circulations and marine ecological
systems. Processes in the open ocean, such as gyres and overturning circulations, have also been affected by changes in
surface wind stress and buoyancy fluxes. Oceanic processes in marginal/coastal seas and the open ocean are intimately
linked through processes that govern cross-shelf exchanges. Flows on shelves, for instance, are influenced by oceanic
gyres through boundary currents and eddy fluxes. Marginal/coastal seas also exert their influences on open-ocean
processes. Thermohaline circulations in the deep open ocean, for example, are driven in part by water-mass
transformations in marginal/coastal seas. To assess and to predict oceanic responses to climate changes, it is imperative
to understand how the open ocean interacts with marginal/coastal seas, and how such interactions are affected by
climate changes. This session provides a venue for sharing interdisciplinary studies that address key linkages of physical
and biogeochemical processes between the open ocean and marginal/coastal seas under a changing climate.

Session Title: Abyssal ocean mixing: from small scale turbulence to large scale meridional overturning circulation
Session Description: Diapycnal mixing is one of the primary mechanisms driving the ocean meridional overturning
circulation (MOC). Full understanding of how mixing drives the MOC, however, requires studies over a wide range of
spatial and temporal scales. Such studies include, but are not limited to, (I) studying the influence of spatial/temporal
variations in mixing on strength and patterns of circulation on regional to global scales, (II) estimating global scale mixing
due to interaction of tides and geostrophic motions with bottom topography, (III) measuring mixing through direct and
indirect observational methods, (IV) studying the underlying physics of stratified turbulence which inform our
parameterization of mixing in models as well as our interpretation of observational data. While in principle no clear
boundaries exist between these topics, in reality more interaction between the research efforts focused on them is
more than needed and will certainly be beneficial to all. To this end, this session aims to bring together the frontiers in
research on various aspects of ocean mixing and circulation. The emphasis will be on connecting the large scale picture
to the small scale theory and observations of mixing. All approaches are welcome as are studies on sensitivity of the
climate to ocean mixing

Session Title: Hot or Not? Interdisciplinary investigations of the drivers and variability of marine biodiversity and
productivity: how do we detect and model change?
Session Description: The ocean is highly heterogeneous in terms of productivity and biodiversity. Upwelling drives
narrow bands of high productivity along eastern boundaries; blooms of varying magnitude and duration punctuate the
seasonal cycles of the open ocean regimes; rich, diverse ecosystems thrive in the polar margins, particularly at oceanic
fronts, polynyas and marginal ice zones. In these systems and others, the magnitude and variability of productivity and
the relationship to planktonic diversity is driven by a complex set of biochemical and physical forcings. Understanding
the mechanisms that drive pulsed or sustained enhancements of productivity is critical to our capacity to model the
response of ocean ecosystems to anthropogenic forcing. Furthermore, linking changes in productivity to planktonic
species composition is needed to understand critical components of ecosystem function, e.g. carbon export. We invite
submissions that address the physical, chemical, and ecological mechanisms that contribute to episodes of high
productivity, as well as submissions that address the overarching question of how we measure and model changes in
marine productivity and biodiversity in ‘bloom’-prone regions. We particularly encourage submissions that are
interdisciplinary or employ novel methodology.

Session Title: Primary Production in the subsurface: mechanisms, key species, significance for export and the marine
biological carbon pump.
Session Description: Our understanding of oceanic primary production and producers has been dominated by sampling
of the surface ocean (typically < 20m). Similarly, our knowledge of global patterns of primary production has been led by
ocean colour measurements from satellite sensors that again, have surface bias. During the 20th Century there were
few systematic attempts to target the subsurface resulting in a gap dating back to Schimper’s pioneering use of closing
nets on the 1898 Valdivia cruise. Over the past two decades, however, a burgeoning suite of observations has
highlighted the significance of subsurface production. A range of mechanisms have been identified including the ability
to grow in low light in subsurface chlorophyll maxima, exploitation of mixing events at the pycnocline/ nutricline,
buoyancy regulation allowing the mining of deep nutrients. Significantly, new research is also demonstrating that this
subsurface production may be of major significance for carbon export. With climate change driving increased ocean
stratification, these styles of subsurface production may become more significant so it is timely to focus on them. This
170 | P a g e
session will aim to bring together observation, theory and modelling of the subsurface to synergistically improve
understanding and to identify new targets and priorities for research.

Session Title: All microorganisms must die: mechanisms of mortality in the planktonic environment
Session Description: Processes that either promote growth or cause mortality drive the abundance of all organisms. As
planktonic organisms are the central currency in the flow of material and nutrients throughout the marine environment,
even small shifts in growth and mortality rates can have large-scale implications for ecosystem structure and
biogeochemical cycling. While much is known about processes that influence growth in the planktonic environment,
little is known regarding the regulation of mortality. This interdisciplinary session invites studies that investigate
mechanisms of mortality in marine microorganisms (e.g. consumption, viral lysis, programmed cell death, allelopathy).
Integrative approaches that connect scales of mortality, from single-cells to the ecosystem level are encouraged. This
session will cover a broad range of topics including: mechanisms and rates of mortality, targeted studies of mortality in
model culture systems, direct and indirect consequences of stress on mortality, comparing competing modes of
mortality, quantifying the consequences of mortality, and modeling efforts.

Session Title: Protistan Mixotrophs: Jacks of all trades or masters of none?
Session Description: Protistan mixotrophs, unicellular eukaryotes that gain energy through a combination of
phototrophic and phagotrophic mechanisms, are omnipresent in aquatic ecosystems. They employ a variety of
171 | P a g e
metabolic strategies, from periodic acquisition of photosynthesis by predominantly heterotrophic organisms to
occasional grazing by plastidic protists, and make important contributions to biogeochemistry. For example, mixotrophs
are bloom-formers in coastal and estuarine ecosystems and act as key nutrient recyclers in oligotrophic gyres. Despite
their significance, many aspects of mixotroph physiology and ecology remain unexplored. In this session, we invite
investigators to present their research on mixotrophic organisms in both marine and freshwater systems, using
laboratory, field, and/or modeling approaches. Studies ranging from cellular processes (e.g., regulation of metabolic
machinery) to community ecology (e.g., species interactions) to ecosystem dynamics (e.g., biogeochemical
consequences) are welcomed.

Session Title: Bridging the gap between lab and sea: integrating experimentation and observation to explore marine
phytoplankton ecology
Session Description: The physiological performance of marine phytoplankton is often dramatically greater in their
natural environment than in laboratory cultures. These differences represent a critical gap that must be addressed in
order to understand niche realization and predict changes in phytoplankton ecology over varied taxonomic, spatial, and
temporal scales. Advances in genomic, biochemical, and ocean observing capabilities are allowing ever more highly
resolved descriptions of ecological complexity in the ocean and point to diverse mechanisms underlying differences in
niche realization: from previously undescribed species diversity to newly uncovered interspecies and bacterial
interactions to specialized adaptations for small- and large-scale physical and chemical heterogeneity. We invite
presenters who are using diverse models and approaches to characterize and address “the gap”, especially those whose
work draws on a combination of field and laboratory observations to better understand ecologically relevant
phytoplankton dynamics at local to global scales.

Session Title: Scaling up phytoplankton ecophysiology from cultures to biogeochemical processes in aquatic
environments: A tribute to the legacy of Dr. Paul J. Harrison
Session Description: Scientific research aimed at understanding biogeochemistry in marine and freshwater systems is
challenged by the logistical constraints of fieldwork, and the complexity and variability of natural environments. Clearly
demonstrating the effects of variables on phytoplankton physiology often requires control that can only be achieved in
the laboratory, e.g. presence of select species, manipulation of single variables, high degrees of replication, and high
spatiotemporal frequency of measurements. However, experimentation under controlled conditions creates inevitable
concerns about ecological relevance. Over several decades, Harrison and collaborators regularly navigated the waters
between lab and field, using a number of approaches that included field manipulation experiments at varying scales.
Such work has involved studies of resource limitation (e.g. nutrients, trace metals, temperature and light), effects of
ocean acidification, and food web energy transfer that extended the phytoplankton investigations to interactions with
their grazers and pathogens, among others. This session will highlight results from ecophysiological studies of
phytoplankton in a range of experimental scenarios (laboratory cultures, field micro- and meso-cosms, andin situ
experiments) that can fill critical gaps in our understanding of large-scale aquatic biogeochemistry.

Session Title: The Magnitude and Variability in Marine Ecosystems on Sub-seasonal Timescales
Session Description: New methods to observe biological production with high temporal resolution and large spatial
coverage provide the ability to explore marine ecosystems on sub-seasonal timescales. Such novel datasets aid our
understanding of how biological and physical processes interact in the surface ocean to sustain marine life.
Biogeochemical models are in development offering ever-increasing spatial resolution, allowing them to resolve smallscale processes dynamically. The ability to address sub-seasonal timescales provides a new opportunity to directly study
processes that affect the biological system, rather than relying on time-integrated data and steady-state assumptions.
This session aims to bring together projects concerning physiological experiments, field observations, analysis of
remotely sensed data, or numerical modeling that addresses questions about bio-physical interactions or biological
173 | P a g e
production on sub-seasonal scales. Some examples are sub-meso scale processes, the importance of extreme events,
seasonal variability in primary production and respiration, different physical processes that control biological
production, and dominating temporal and spatial scales.

Session Title: Technological Advancements in Phytoplankton Ecology: Observation Techniques and Platforms, Data
Analysis and Interpretation, and Model Development
Session Description: Phytoplankton are a vital component of the aquatic ecosystem and affect water chemistry through
nutrient uptake, alteration, and excretion. Shifts in phytoplankton community structure serve as indicators of
environmental perturbations to aquatic systems, including climate change, eutrophication, and pollution. Furthermore,
bloom-forming species can cause negative effects including hypoxia, high turbidity, or toxicity.
Technologies for assessing phytoplankton distribution and ecological variables have improved in efficiency and
spatial/temporal resolution through the development and advancement of laboratory techniques, adaptation to new insitu platforms, and incorporation into regional observation systems.
Phytoplankton observations range from simple detection (e.g. remote sensing, optical techniques) to species
discrimination (e.g. microscopy, spectral fingerprinting, molecular approaches), to community structure determination
(i.e. chemotaxonomic analysis). Additionally, laboratory and in-situ measurements of phycotoxins, macro- and
micronutrients, and chemical and physical variables provide a critical ecological context for phytoplankton observations.
In turn, advancements in data interpretation and modeling offer insight into phycological observations and allow for
forecasting and prediction of harmful algal blooms, providing resource managers with tools to mitigate negative effects.
We invite presentations focused on the development or use of new or improved observation technologies, data analysis
and interpretation techniques, and model development that address the many aspects of phytoplankton ecology.

Session Title: Policy Impacts of Aquatic Science: Communicating Science to Policymakers
Session Description: Bringing science to the forefront of policy discussions is important for sound decision-making and
the sustainability of the world's aquatic systems. Aquatic science and research can inform policies to address some of
the most challenging societal problems including rising sea levels and the impact of pollution on aquatic ecosystems.
Understanding the interaction between the aquatic environment and our natural resources, public and environmental
safety, national security, and the global economy requires a wide range of expertise, including the scientific community.
Many scientists want to broaden the impact of their research, but don’t know how or where to start. In this session,
presenters will discuss how they've engaged with policymakers, what policymakers want to know, and what kinds of
contributions scientists can make to policy development and implementation.

Session Title: Dynamic Ocean Management: Managing at Finer Scales for Mobile Ocean Resources
Session Description: Dynamic ocean management aims to respond to the movement of managed species, ocean users,
and underlying ocean features. Higher temporal resolution of management measures can create efficiency gains and
allows managers to address problems that were previously intractable. Understanding patterns in space and time for
both target and non-target species can allow management to explicitly respond to the dynamic movements of marine
animals and people that rely on them. Dynamic approaches are particularly important for highly mobile species as well
as resource users that follow features such as fronts and eddies that evolve rapidly in space and time. Advances in
remote sensing, archival tagging, hand-held technology, and species-distribution models have improved our ability to
predict areas of low to high risk of unwanted species interactions in near-real time. That information can be
disseminated to alert users to changing dynamic management areas via website and mobile applications. This session
will explore (1) life history traits and ecosystems that may benefit from dynamic ocean management approaches; (2)
175 | P a g e
how both human and marine resources respond to dynamic oceanography; (3) empirical examples to help quantify the
efficacy and efficiency of dynamic management; and (4) ultimately data frameworks that can improve responsiveness of
ocean management.

core, transitional in nature. These technologies cross multiple boundaries, both regulatory and physical, and their
success requires our best technological development, science, and policy to ensure that they are environmentally and

Session Title: Integrating Science And Management At The Coastal Interface: Landscape-Based Approaches And
Application To Watershed, Coastal, And Ocean Resource Management
Session Description: The growing complexity of natural resource users, jurisdictions, and regulatory authorities has
placed a greater emphasis on integrated management at landscape or ecosystem scales. Largely because of the scope of
those authorities, the management of watershed, coastal, and ocean systems and their resources has developed
independently and at different paces, despite the strong interconnectivity of these systems. This session will consider
three applications of integrated management – watershed, coastal zone, and marine ecosystem – and their nexus. These
management applications are the focus because of the need for their coordination at, and integration across, the landocean interface. Such integrated approaches have been widely-recommended as key components of climate adaptation
strategies.
This session brings together policy experts, scientists, and managers from these landscapes to: 1) highlight resource
managers' and users' needs, and what scientists are doing to meet them, 2) share lessons from each spatial
management sector, 3) identify common strategies and principles to these approaches, and 4) discuss how to integrate
science and management across the coastal interface as these environments change over time. The session will contrast
the recent application to marine ecosystems, to more seasoned efforts in the coastal zone and the even longer history of
watershed management.

Session Title: Making National Policy Work Locally: Approaches For Implementing The National Ocean Policy At
Regional, State, And Local Levels Through Ecosystem-Based Management
Session Description: The National Ocean Policy identifies ecosystem-based management (EBM) as a foundation for
providing sound science-based and adaptable management to maintain the health, productivity, and resilience of U.S.
ocean, coastal, and Great Lakes ecosystems, and the many, diverse benefits they provide. Furthermore, EBM is an
important approach for efficient and effective interagency, multi-jurisdictional, and cross-sectoral marine planning and
management that is consistent with and authorized by many existing Federal, Tribal, State, and local statutes and
authorities.
To become part of the marine planning and management culture, EBM must be applied and proven through local and
regional examples, and meet management objectives at those scales and for those jurisdictions. To facilitate this, States,
177 | P a g e
Tribes, and key stakeholders should be incentivized and empowered to collaborate with Federal agencies from the
outset as partners on its implementation.
This session brings together EBM researchers, planners, and decision makers to present the regional needs (the
management) for EBM tools (the science) that help regional marine planning within the context of National policy.
Presentations will advance the conversation about applying EBM by highlighting key challenges to its implementation,
tools and trainings available, and lessons learned from pilot projects. EBM principles, theory, and case studies will be
presented.

Session ID: 7999
Session Title: Observations and Modeling of Physical Processes Along Coral Reef-lined Coasts
Session Description: Coral reefs function as protective barriers that shelter many of the world’s tropical and sub-tropical
coastlines from storm and tsunami waves while producing carbonate sediment that form most of their beaches and reef
islands. Physical processes along these coasts tend to be quite distinct from open coast shorelines because
hydrodynamics over coral reefs tend to be strongly influenced by steep slopes, complex topography, and large, often
spatially variable, bottom roughness. Sediment transport is complicated by the small-scale interactions with corals, as
well as in situ biogenic sediment production and diagenesis that ultimately make determining sediment budgets in these
areas challenging. Although reefs reduce wave energy reaching the coastline, their role in shaping coastal morphology
through short-term processes such as storms and longer-term changes in oceanographic forcing or sediment supply is
often unclear. This session aims to synthesize recent advances in this broad, multi-disciplinary research area, including
hydrodynamic and sedimentologic processes in reef environments and their resulting impacts on coastal
geomorphology, ecosystems, and hazards both at present and under future climate-change scenarios. Studies focusing
on a diversity of reef types using process-based field, laboratory, and numerical modelling approaches are encouraged.

Session Title: Coral Reef Calcification in a Changing Ocean: from Microscale Mechanisms to Macroscale Responses
Session Description: Coral reefs support an estimated 500 million people worldwide. Yet anthropogenic CO2 emissions
are driving unprecedented changes in the tropical oceans, where the vast majority of shallow water reefs exist. Rapid
warming, acidification and declining productivity will have potentially deleterious effects on calcification, the
fundamental process of reef building. However, quantitative projections of coral reef futures are limited in part, by gaps
in our understanding of the calcification process – from the production of crystals to the building of reefs – and of the
response of coral and coral reef calcification to multiple, interactive global change stressors on timescales of days to
decades. This session invites contributions from biologists, marine chemists, physical oceanographers, ecologists and
geochemists to bring diverse expertise and new perspectives to a subject of global significance. We encourage
submissions from field, laboratory, and theoretical studies that offer new insights into the fundamental mechanisms of
coral calcification and reef building, and the response of calcification to global change at the cellular, colony and
ecosystem scale. Paleoperspectives on calcification responses to past global changes are encouraged as well as papers
that offer insights into potential for adaptation.

Session Title: Detecting, Characterizing, and Understanding Impacts of Ocean Eddies
Session Description: Mesoscale and submesoscale eddies are ubiquitous in the world ocean, and have significant effects
on the large-scale circulation by transporting and mixing heat, freshwater, nutrients, momentum, and vorticity. Even as
model resolution improves, the need to parameterize eddy effects does not diminish. As a consequence, we are
continually seeking new ways to quantify and characterize eddy impacts. An improved appreciation of eddy impacts is
both a necessary ingredient in our understanding of the oceanic circulation, as well as an invaluable guide for correctly
representing the effects of unresolved scales in numerical ocean models.
This session invites reports on novel ideas for better detecting, characterizing, and understanding eddy impacts from the
theoretical, observational and modeling communities. These include development or application of new analysis
techniques, instrumentation, measurement approaches based on satellite or in-situ data, model diagnostics, or
mathematical frameworks for identifying and quantifying eddies or their impacts on the ocean circulation. Our objective
is to stimulate out-of-the-box thinking about how to measure and understand eddy impacts that will make the most of
the rapidly growing sophistication of the datasets and numerical models that are currently available, and to motivate
future studies on the role of eddies in the ocean circulation.
