International audience In this study we report particulate organic carbon (POC) export fluxes for different biogeochemical basins in the North Atlantic as part of the GEOTRACES GA01 expedition (GEOVIDE, May-June 2014). Surface POC export fluxes were deduced by combining export fluxes of total Thoriu...
