Recent publication: Seasonal and annual budget of dissolved inorganic carbon in the NW Med deep convection area

Researchers from LEGOS, NIOZ, LOV, MIO, Espace-Dev, SCCWRP, LOCEAN, and CEFREM investigated the seasonal to annual cycle and budget of dissolved inorganic carbon in the deep convection area of the north-western Mediterranean, using a coupled physical-biogeochemical model. Their results show that the northwestern Mediterranean Sea’s deep-convection region was a moderate sink of 0.5 mol C m−2 yr−1 of CO2 for the atmosphere during the period September 2012-September 2013. They highlight the major roles in the annual dissolved inorganic carbon budget of both the biogeochemical and physical fluxes in the surface layer (from the surface to 150 m depth), that were 1 order of magnitude higher than the air–sea CO2 flux.

These results are published in Biogeosciences:
