Sources and Paths of the Lower Branch of the Abyssal Overturning Circulation Open
Lagrangian analysis using the velocity field of the Southern Ocean State Estimate (SOSE) at 1/6° resolution quantifies the origin of the lower branch of the abyssal circulation south of 30°S. Antarctic waters from 65°S contribute 62% of th…

Reconstructing historical salinity fields over the 20th century using a data-driven method and Argo data Open
Ocean salinity is a fundamental variable that determines seawater density and, therefore, stratification and oceanic dynamics. To understand how salinity is affected and how it contributes to ocean processes, its variability must be studie…

Reconstructing the Ocean State Using Argo Data and a Data-Driven Method Open
Over the past two decades, Argo profiles have provided unprecedented insight into the global patterns of space and time variability of ocean temperature and salinity, significantly reducing associated uncertainties. However, analyzing such…

Reanalyses (1930-2001) of temperature and salinity in the upper 500 meters of the Tropical Pacific (20S-20N) Open
RedAnDA TS, UnivarS and UnivarT are the different versions of RedAnDA, applied respectively to temperature-salinity (coupled), salinity and temperature monthly reconstructions. The coupled approach uses bivariate 3D EOFs with density-weigh…

Sensitivity of gyre-scale marine connectivity estimates to fine-scale circulation Open
We investigated the connectivity properties of an idealized western boundary current system separating two ocean gyres, where the flow is characterized by a well-defined mean circulation as well as energetic fine-scale features (i.e., meso…

Influence of waves on the three-dimensional distribution of plastic in the ocean Open
The world's oceans are confronted with plastic pollution, 80% of which is of terrestrial origin, flowing mainly from the mismanaged waste of coastal populations and to a less extent, from river discharge. To study the fate of this pollutio…

Ocean Acidification From Below in the Tropical Pacific Open
Identifying ocean acidification and its controlling mechanisms is an important priority within the broader question of understanding how sustained anthropogenic CO 2 emissions are harming the health of the ocean. Through extensive analysis…

Anticyclonic Eddies Connecting the Western Boundaries of Indian and Atlantic Oceans Open
The Indo‐Atlantic interocean exchanges achieved by Agulhas Rings are tightly linked to global ocean circulation and climate. Yet they are still poorly understood because they are difficult to identify and follow. We propose here an origina…

Large- to submesoscale surface circulation and its implications on biogeochemical/biological horizontal distributions during the OUTPACE cruise (southwest Pacific) Open
The patterns of the large-scale, meso- and submesoscale surface circulation on biogeochemical and biological distributions are examined in the western tropical South Pacific (WTSP) in the context of the OUTPACE cruise (February–April 2015)…

Mesoscale and Submesoscale Processes in the Southeast Atlantic and Their Impact on the Regional Thermohaline Structure Open
The turbulent processes in the Cape Basin, the southeasternmost gate of the Atlantic Ocean, play a key role in the transport and mixing of upper to intermediate water masses entering the area from the Indian Ocean, making them especially r…
