Title

Comparative study of the processes controlling carbon export in Southern Ocean environments characterised by a different hydrodynamical and ecological functioning

Project aims

The proposal focuses on the functioning of the biological carbon pump in the Southern Ocean. The objectives are to understand spatio-temporal variability of primary production as a function of phytoplankton composition and available nutrients and to evaluate carbon exportation from the surface ocean and its mineralisation in the ocean's interior.
