Variations in the world's ocean heat storage and its associated volume changes are a key factor to gauge global warming and to
assess the earth's energy and sea level budget. Estimating global ocean heat content (GOHC) and global steric sea level (GSSL)
with temperature/salinity data from the Argo network reveals a positive change of 0.5 +/- 0.1 W m(-2) (applied to the surface area
of the ocean) and 0.5 +/- 0.1 mm year(-1) during the years 2005 to 2012, averaged between 60 degrees S and 60 degrees N and the
10-1500m depth layer. In this study, we present an intercomparison of three global ocean observing systems: the Argo network,
satellite gravimetry from GRACE and satellite altimetry. Their consistency is investigated from an Argo perspective at global...

Autores: Reverdin, Gilles; Morisset, S.; Bellenger, H.; Boutin, J.; Martin, N.; Blouch, P.; Rolland, Jean; Gaillard, Fabienne;
Bouruet-aubertot, P.; Ward, B.
This study describes how the hull temperature (Ttop) measurements from multisensor surface velocity program (SVP) drifters can
be combined with other measurements to provide quantitative information on near-surface vertical temperature stratification
during large daily cycles. First, Ttop is compared to the temperature measured at 17 -cm depth from a float tethered to the SVP
drifter. These 2007-12 SVP drifters present a larger daily cycle by 1%-3% for 1 degrees-2 degrees C daily cycle amplitudes, with
a maximum difference close to the local noon. The difference could result from flow around the SVP drifter in the presence of
temperature stratification in the top 20 cm of the water column but also from a small influence of internal drifter temperature on...

Thermosalinomètres des navires de recherche : procédures de validation temps différé
Provedor de dados: 5
Autores: Krieger, Magali; Diverres, Denis; Gaillard, Fabienne; Gouriou, Yves; Grelet, Jacques.
La collecte systématique des mesures de température et de salinité de surface par les navires de recherche a été initiée en 1999,
lors de la phase pilote du projet Coriolis. Aujourd'hui tous les navires hauturiers sont dotés de systèmes homogènes, qualifiés et
suivis, ils transmettent leurs données en temps réel au centre de données Coriolis et des échantillons d'eau de mer sont
régulièrement prélevés à bord puis acheminés vers le laboratoire d'analyse. Malgré le soin accordé à l'étalonnage des systèmes de
mesure et leur nettoyage régulier, il est fréquent d'observer une dérive dans la mesure de conductivité. Il est donc important, en
particulier pour le suivi à long terme et les études climatiques, de contrôler et corriger ces mesures. Ce document décrit...

Multi-angular images of the brightness temperature (TB) of the Earth at 1.4 GHz are reconstructed from the Soil Moisture and
Ocean Salinity (SMOS) satellite sensor data since end 2009. Sea surface salinity (SSS) products remote sensing from space is
being attempted using these data over the world oceans. The quality of the first version of the European Space Agency operational
Level 2 (L2) SSS swath products is assessed in this paper, using satellite/in situ SSS data match-ups that were collected over the
second half of 2010. This database reveals that 95% of the SMOS L2 products show a global error standard deviation on the order
of ∼1.3 practical salinity scale. Simple spatiotemporal aggregation of the L2 products to generate monthly SSS maps at 1◦ × 1◦...

Observation of spiciness interannual variability in the Pacific pycnocline
Provedor de dados: 5
Autores: Kolodziejczyk, Nicolas; Gaillard, Fabienne.
Monthly gridded fields predominantly based on global Argo in situ temperature and salinity data are used to analyze the
density-compensated anomaly of salinity (spiciness anomaly) in the pycnocline of the subtropical and tropical Pacific Ocean
between 2004 and 2011. Interannual variability in the formation, propagation and fate of spiciness anomalies are investigated. The
spiciness anomalies propagate on the isopycnal surface sq = 25.5 along the subtropical-tropical pycnocline advected by the mean
currents. They reach the Pacific Western Tropics in about 5–6 years in the Southern Hemisphere and about 7–8 years in the
Northern Hemisphere. Their amplitude strongly diminishes along the way and only very weak spiciness anomalies seem to reach
the equator in...

In-situ based reanalysis of the global ocean temperature and salinity with ISAS: variability of the heat
content and steric height
Provedor de dados: 5
Autores: Gaillard, Fabienne; Reynaud, Thierry; Thierry, Virginie; Kolodziejczyk, Nicolas; Von Schuckmann, Karina.
The In Situ Analysis System (ISAS) was developed to produce gridded fields of temperature and salinity that preserve as much as
possible the time and space sampling capabilities of the Argo network of profiling floats. Since the first global re-analysis
performed in 2009, the system has evolved and a careful delayed mode processing of the 2002-2012 dataset has been carried out
using version 6 of ISAS and updating the statistics to produce the ISAS13 analysis. This last version is now implemented as the
operational analysis tool at the Coriolis data centre. The robustness of the results with respect to the system evolution is explored
through global quantities of climatological interest: the Ocean Heat Content and the Steric Height. Estimates of errors...

ISAS-Tool Version 6 : Method and configuration
Provedor de dados: 5
Autores: Gaillard, Fabienne.
ISAS (In Situ Analysis System) is an analysis tool for the temperature and salinity fields. Originally designed for the synthesis of
ARGO dataset, it has been tested for the first time on the POMME area in the North-East Atlantic in 2000, it was later extended to
the Atlantic and the Global ocean as the Argo array was setting up. It is developed and maintained at LPO (Laboratoire de
Physique des Océans) within the Argo Observing Service (SO-ARGO) where it is used for research purposes on ocean variability.
ISAS is made available to the Coriolis datacenter for exploitation in operational mode. It can accommodate a wide range of in situ
measurements if they are provided in the standard NetCdf format distributed by the Coriolis datacenter...

Low-frequency thermohaline variability in the Subtropical South Atlantic pycnocline during
2002-2013
Provedor de dados: 5
Autores: Kolodziejczyk, Nicolas; Reverdin, Gilles; Gaillard, Fabienne; Lazar, Alban.
Low-frequency variability of spiciness is observed in the Subtropical South Atlantic over the period 2002–2013 with the Argo
gridded product In Situ Analysis System. Within the pycnocline, spiciness anomalies propagate at a mean speed of 0.04 ± 0.02 m
s−1, the same speed as the gyre mean circulation, from the Agulhas Retroflection region off South Africa (~35°S–20°E) toward
the South American coast (~18°S–35°W). After 2010, propagation is still found, but stationary local spiciness generation is also
found over the Subtropical South Atlantic. This spiciness increase is associated with high values of vertical Turner angle below
the mixed layer base during late winter. This suggests spice injection resulting from penetrative convective mixing due to air-sea...

Global hydrographic variability patterns during 2003-2008
Provedor de dados: 5
Autores: Von Schuckmann, Karina; Gaillard, Fabienne; Le Traon, Pierre-yves.
Monthly gridded global temperature and salinity fields from the near-surface layer down to 2000 m depth based on Argo
measurements are used to analyze large-scale variability patterns on annual to interannual time scales during the years 2003-2008.
Previous estimates of global hydrographic fluctuations have been derived using different data sets, partly on the basis of scarce
sampling. The substantial advantage of this study includes a detailed summary of global variability patterns based on a single and
more uniform database. In the upper 400 m, regions of strong seasonal salinity changes differ from regions of strong seasonal
temperature changes, and large amplitudes of seasonal salinity are observed in the upper tropical and subpolar global ocean....

Variability of the Heat and Salt Budget in the Subtropical Southeastern Pacific Mixed Layer between
2004 and 2010: Spice Injection Mechanism
Provedor de dados: 5
Autores: Kolodziejczyk, Nicolas; Gaillard, Fabienne.
The mixed layer heat and salt budget in the southeastern subtropical Pacific are estimated using 7 years (2004-10) of
Argo-profiling float data, surface fluxes, precipitation, surface velocity data, and wind observations and reanalysis. In this region,
the mixed layer heat budget is characterized by a strong annual cycle mainly modulated by the shortwave radiation annual cycle.
During the austral fall and winter, the shortwave radiation input minimum is overwhelmed by the heat loss mainly because of the
latent heat flux. The mixed layer salt budget also presents a strong annual cycle with a minimum of salt content during the late
austral winter. In contrast with the heat budget, the salt budget is mainly driven by the unresolved terms computed as the...

Sea surface freshening inferred from SMOS and ARGO salinity: impact of rain
Provedor de dados: 5
Autores: Boutin, Jacqueline; Martin, Nicolas; Reverdin, Gilles; Yin, Xiaoming; Gaillard, Fabienne.
The sea surface salinity (SSS) measured from space by the Soil Moisture and Ocean Salinity (SMOS) mission has recently been
revisited by the European Space Agency first campaign reprocessing. We show that, with respect to the previous version, biases
close to land and ice greatly decrease. The accuracy of SMOS SSS averaged over 10 days, 100 x 100 km(2) in the open ocean and
estimated by comparison to ARGO (Array for Real-Time Geostrophic Oceanography) SSS is on the order of 0.3-0.4 in tropical
and subtropical regions and 0.5 in a cold region. The averaged negative SSS bias (-0.1) observed in the tropical Pacific Ocean
between 5 degrees N and 15 degrees N, relatively to other regions, is suppressed when SMOS observations concomitant with rain

some spikes. Sudden salinity jumps are found in drifter salinity records that are not always associated with temperature jumps, in
particular in the wet tropics. A method is proposed to decide whether and how to correct those jumps, and the uncertainty in the
correction applied. Northeast of South America, in a region influenced by the Amazon plume and fresh coastal water, drifter

The Argo array, by offering simultaneously global coverage and high vertical resolution, made the monitoring of inter-annual and
decadal variability of the ocean interior possible. In the ARIVO project, we have initiated the production of gridded monthly
fields of temperature and salinity using an optimal analysis tool and designed an iterative approach to combine near-real time and
delayed mode data. The monthly gridded fields are averaged over time to produce the reference state needed by climatological
studies, dynamical modeling and reconstruction methods themselves. Higher degree statistics such as variances and extreme
values are later derived. Global indices (heat content, dynamical height) and corresponding error bars are also computed.

Many oceanographic applications require the positioning of the underwater sensor at measurement times. We consider here the
case of subsurface moored tomographic instruments, where the distance between source and receiver must be known within a few
meters. For that purpose, a long baseline array is deployed: this system includes a navigator, attached to the mooring element and
an array of three transponders set on the ocean bottom. To process the navigation data collected with such system, we have
developed a method based on optimal estimation. The triangulation problem is not a basic spherical constraints one and the
specificity of deep underwater positioning, related to the variability of the ocean sound speed profile are pointed out. Correcting

(September 2000 - October 2001), over a 8 degrees square area centered on 18 degrees W, 42 degrees N. In order to synthesized
the in-situ physical observations, and merge them with satellite altimetry and surface fluxes datasets, a simplified Kalman filter
has been designed. Daily fields of temperature, salinity, and stream function were produced on a regular grid over a full seasonal
cycle. We propose here the gridded fields (KA_ files) and the in-situ datasets used by the analysis (Data_ files).

Use of the analysis system for monitoring the ARGO sensors drifts
Provedor de dados: 5
Autores: Autret, Emmanuelle; Gaillard, Fabienne.
In the previous letter, we briefly presented the analysis system operational at the Coriolis datacen-ter. This system both synthetises
data sets by pro-ducing temperature and salinity gridded fields and checks for quality the data from the Coriolis data-base in real
time. We will focus here on this latter application of the system. We will discuss of the use of the analysis tool to perform the real
time and delayed mode quality control (QC), particularly of the ARGO profilers. Those two modes of QC are fundamentally
different. Real time QC are meant to flag the data according to pre-defined quality levels, these tests must not slow down the data
flow, they are therefore only qualitative. The delayed mode QC has to be quantitative, one wish to detect and...

Variability in the ICES/NAFO region between 1950 and 2009: observations from the ICES Report on
Ocean Climate
Provedor de dados: 5
Autores: Hughes, Sarah L.; Holliday, N. Penny; Gaillard, Fabienne.
The ICES Report on Ocean Climate presents the latest information on the status and trends of sea temperature and salinity in the
North Atlantic and Nordic Seas. It is the main product of the ICES Working Group on Oceanic Hydrography, published annually.
Bringing together multiple time-series from across the ICES and NAFO regions offers insight into the concurrent spatial and
temporal trends in ocean temperature and salinity. This paper presents an overview of the physical variability in the North Atlantic
Ocean at decadal and longer time-scales and reviews the current state of understanding of the causes and mechanisms of this
variability. Between the 1960s and the 1990s, the North Atlantic Oscillation (NAO) index increased from a persistent negative

Errors in SMOS Sea Surface Salinity and their dependency on a priori wind speed
Provedor de dados: 5
Autores: Yin, Xiaobin; Boutin, Jacqueline; Martin, Nicolas; Spurgeon, Paul; Vergely, Jean-luc; Gaillard, Fabienne.
The wind speed (WS) provided by the European Centre for Medium-Range Weather Forecasts (ECMWF) is used to initialize the
retrieval process of WS and Sea Surface Salinity (SSS) obtained by the Soil Moisture and Ocean Salinity (SMOS) mission. This
process compensates for the lack of onboard instrument providing a measure of ocean surface WS independent of the L-band
radiometer measurements. The SMOS-retrieved WS in the center of the swath (± 300 km) is adjusted regarding to its a priori
estimate. The quality of the SMOS-retrieved SSS (SSSSMOS) is better at the center of the swath than at the edge of the swatch
because the larger number of brightness temperature measurements available at the center of the swath reduces the effects of noise
and because the...

SMOS salinity in the subtropical north Atlantic salinity maximum: 1. Comparison with Aquarius and
in situ salinity
Provedor de dados: 5
Autores: Hernandez, Olga; Boutin, Jacqueline; Kolodziejczyk, Nicolas; Reverdin, Gilles; Martin, Nicolas; Gaillard, Fabienne;
Reul, Nicolas; Vergely, J. L.
Sea surface salinity (SSS) measured from space by the Soil Moisture and Ocean Salinity (SMOS) mission is validated in the
subtropical North Atlantic Ocean. 39 transects of ships of opportunity equipped with thermosalinographs (TSG) crossed that
region from 2010 to 2012, providing a large database of ground truth SSS. SMOS SSS is also compared to Aquarius SSS. Large
seasonal biases remain in SMOS and Aquarius SSS. In order to look at the capability of satellite SSS to monitor spatial variability,
especially at scales less than 300 km (not monitored with the Argo network), we first apply a monthly bias correction derived
from satellite SSS and In Situ Analysis System (ISAS) SSS differences averaged over the studied region. Ship SSS averaged over

A four-dimensional analysis of the thermal structure in the Gulf of Lion
Provedor de dados: 5
Autores: Gaillard, Fabienne; Desaubies, Yves; Send, Uwe; Schott, Fritz.
The Theoretical and Experimental Tomography in the Sea Experiment (THETIS 1) took place in the Gulf of Lion to observe the
evolution of the temperature field and the process of deep convection during the 1991-1992 winter. The temperature
measurements consist, of moored sensors, conductivity-temperature-depth and expendable bathythermograph surveys, ana
acoustic tomography. Because of this diverse data set and since the field evolves rather fast, the analysis uses a unified
framework, based on estimation theory and implementing a Kalman filter. The resolution and the errors associated with the model
are systematically estimated. Temperature is a good tracer of water masses. The time-evolving three-dimensional view of the field
resulting from the analysis...

Uncertainty in ocean analysis methods and deficiencies in the observing system are major obstacles for the reliable reconstruction
of the past ocean climate. The variety of existing ocean reanalyses is exploited in a multi-reanalysis ensemble to improve the
ocean state estimation and to gauge uncertainty levels. The ensemble-based analysis of signal-to-noise ratio allows the
identification of ocean characteristics for which the estimation is robust (such as tropical mixed-layer-depth, upper ocean heat
content), and where large uncertainty exists (deep ocean, Southern Ocean, sea ice thickness, salinity), providing guidance for
future enhancement of the observing and data assimilation systems.

The Bay of Biscay climatology is the synthesis of all the in situ data collected in the bay of Biscay area as far as 15°W, in the 20th
century and mainly by IFREMER, SHOM, and WDCA. It shows temperature and salinity monthly information through the whole
water column with a 1/10 degree resolution. The resulting atlas was produced by an optimal analysis which can reflect different
scales: shelf and abyssal plain. A fine scale on the coast reveals all the local effects, including plume and upwelling, and a large
scale on the shelf where a slower signal is obtained due to the large scale circulation

Autores: Bouruet-aubertot, Pascale; Mercier, Herle; Gaillard, Fabienne; Lherminier, Pascale.
The purpose of this paper is to characterize inertia-gravity waves (IGW) activity and to investigate the variability of these waves
in relationship to atmospheric forcing and larger-scale motions. To this aim, we analyzed Eulerian measurements of horizontal
currents and temperature collected over 1 year during the Programme Océan Multidisciplinaire Méso Echelle (POMME). We
focused on the main frequency components of the IGW spectrum, namely the inertial frequency f and the semidiurnal frequency
M2. Time evolution of the relative energy of these two components gave evidence of isolated events of high intensity. We
performed a detailed analysis of these events and identified mechanisms of generation of these waves. Localized spots of intense,
near-inertial...

Variability of the meridional overturning circulation at the Greenland–Portugal OVIDE section from
1993 to 2010

Falina, Anastasia; Ferron, Bruno; Gourcuff, Claire; Huck, Thierry; Thierry, Virginie.
The meridional overturning circulation (MOC) in the North Atlantic transports heat from the subtropics to high latitudes and
hence plays an important role in the Earth’s climate. A region crucial for the MOC is the northern North Atlantic and the adjacent
Nordic Seas, where waters transported northward in the MOC upper limb progressively cool, gain density and eventually sink.
Here we discuss the variability of the gyre circulation, the MOC and heat flux as quantified from a joint analysis of hydrographic
and velocity data from six repeats of the Greenland to Portugal OVIDE section (1997–2010), satellite altimetry and Argo float
measurements. For each repeat of the OVIDE section, the full-depth absolute circulation and transports were assessed using an...

rigorous adjustment on water samples lead to reach an accuracy of a few 10-² PSS in salinity or evenless. Global comparison with

Mixed-layer salinity budget in the tropical Indian Ocean: seasonal cycle based only on observations
Provedor de dados: 5
Autores: Da-allada, Casimir Yelognisse; Gaillard, Fabienne; Kolodziejczyk, Nicolas.
The mixed-layer salinity (MLS) budget in the tropical Indian Ocean is estimated from a combination of satellite products and in
situ observations over the 2004-2012 period, to investigate the mechanisms controlling the seasonal MLS variability. In contrast
with previous studies in the tropical Indian Ocean, our results reveal that the coverage, resolution, and quality of available
observations are now sufficient to approach a closed monthly climatology seasonal salt budget. In the South-central Arabian Sea
and South-western Tropical Indian Ocean (SCAS and STIO, respectively), where seasonal variability of the MLS is pronounced,
the monthly MLS tendency terms are well captured by the diagnostic. In the SCAS region, in agreement with previous results,
