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:

A digital twin of the Nokoué Lagoon to anticipate floodings and pollutions

Located in Benin, West Africa, Nokoué Lagoon is a vast shallow water body (~150 km²), fed by saltwater from the Atlantic Ocean and freshwater from the Ouémé and Sô watersheds (Figure 2). In addition to its natural variability, the lagoon is subjected to considerable anthropogenic pressure, primarily due to pollutant discharges from lakeside villages lacking […]

Second ILICO Integration workshop on marine heat waves

Since 2022, a succession of marine heat waves have been observed along the metropolitan french coasts. These have had devastating consequences for marine ecosystems (species distribution, mass migrations, high mortality) and major socio-economic repercussions (fishing, aquaculture, tourism). The Integration group, formed in 2023 and made up of researchers, lecturers/researchers and managers, brings together different areas […]
