Global breakout group:
Re-thinking after remarks from M.Leinen, R.Weller, J.Orcutt:
• Given funding constraints we cannot build a global system
• Re-focus on building a system that addresses global science issues in innovative
transformative ways, not exhaustive (regionally, issues, disciplines) and
providing complete coverage !
• Goal is not to provide sustained observations to a network like GOOS or users
in various disciplines, but to build new capabilities that can be used later in
development of an IOOS/GOOS.
• Bring out more clearly the #1 science questions that can be answered with the
system, and target the system more clearly towards these
• formulate one global primary question per discipline and ask for 2 globally
important/critical locations to address these.... (hopefully will find again some of
the original sites...)
We could group the science questions into:
response of the ocean to surface and subsurface forcing, and internal variability.

Role of hi-lat sourthern ocean in climate change and variability (physical and
biogeochemical and )
What is the effect of unique hi-wind processes on air-sea fluxes ?
How will CO2 uptake affect biogeochemical cycles ?
The effect of changing aerosol forcing on changing ocean productivity and human
health ?
How will changing surface physical forcing due to climate change perturb ocean
ecosystem and flux of carbon to the deep sea and sea floor ?
What is the role of the oceans in preserving global biodiversity ?
What is the interplay between tectonic and volcanic forces and biogeochemistry and
ecology of the oceans ?
What is the mantle circulation that drives plate tectonics ? What is the role of the
superplumes in global mantle circulation ? How does the rotation of the earths inner
core affect length of day and how does interact with the hydrosphere ?
Can we detect changes in the meridional heat flux of the oceans ?
What is the role of eddy fluxes in the evolution of the physics, biology and chemistry
of the upper ocean ?
How do subtropic and subarctic gyres respond to wind and large-scale climate
forcing ?
How does ocean interior heat content affect sealevel rise ?
What is the space-time geography of energy input and dissipation in the ocean ?
1.
How will changing physical forcing due to climate change perturb ocean ecosystem
and flux of carbon to the deep sea and sea floor ? (Includes CO2 impact on
biogeochemical cycles.)
2.
Ecosystem community changes/ Biodiversity/ contrasting regime....
3.
What are the linkages between tectonic and volcanic processes in the ocean crust,
from its formation to its destruction, and ocean ecology and biogeochemistry, both
above and below the seafloor ? (Ridge/Margins processes)
4.
What is the scale, shape and nature of heterogeneities in the earth‘s mantle and core,
and how do they relate to key processes such as plate tectonics, generation of the
earth‘s magnetic field, or variations in earth‘s rotation ?
5.
Impact of extreme and/or episodic conditions and of aerosol/dust on air-sea fluxes....
(physical and biogeochemical)
6.
Over-arching ocean circulation/P.O. question...
Can we detect changes in the meridional heat flux of the oceans ?
What is the role of eddy fluxes in the evolution of the physics, biology and chemistry of the upper
ocean ?
How do subtropic and subarctic gyres respond to wind and large-scale climate forcing ?
How does ocean interior heat content affect sealevel rise ?
What is the space-time geography of energy input and dissipation in the ocean ?
White: questions 1&2 (biogeochem, ecology, biodiversity)
yellow: question 3 (ridge and subduction sites)
Pink: question 4 (seismic studies of earth structure)
Green: question 5 (air-sea flux)
Question 6 still missing
Still to do:
• Introduce prime circulation/P.O. science driver
• Choose between several Ridge/Margin and seismic and bio/eco site options
• sharpen justifications in terms of critical and unstudied processes of global
relevance
• Re-introduce multi-disciplinarity
• Define better the transformative infrastructure needs (instrumentation, platforms,
sampling, communication/control)
• Consider possible phasing, taking into account other programs, both national and
international
• formulate recommendations to STAC
• address the breakout group questions
