Modelling the effect of iron fertilization on dimethylsulphide emissions in the Southern Ocean
International audience In this study, we use a 3D ocean biogeochemical model to explore the relationship between iron fertilization and dimethylsulphide (DMS) production in the Southern Ocean. The model is able to reproduce the observed decoupling between high productivity and DMS-rich waters becaus...
