The cruise Mobydick takes place from 18 February to 28 March 2018 on board of Marion Dufresne.
The objective of MOBYDICK is to study the links that exist between the biological pump of carbon and the food web structure. To address this issue MOBYDICK proposes a novel approach by considering the entire food web from microbes to top predators and by investigating the hitherto poorly studied relationships between biogeochemical fluxes and biodiversity. The dataset required to test the hypotheses proposed in MOBYDICK will be acquired during an oceanographic campaign off Kerguelen Island (Southern Ocean). In this well-documented area, 2 contrasted ecosystems ‘Low Biomass Low Export’ and ‘High Biomass Low Export’ coexist.
