Coastal ecosystem functioning

Through observational and modeling efforts focused on the Senegalese upwelling region (ANR SOLAB), key processes of the ecosystem functioning, such as severe episodic anoxy, are under scrutiny.

Decadal chlorophyll variability

Satellite Chlorophyll data are yet too short to allow meaningful characterization of its decadal variability. New reconstruction method based on machine learning technics are under-investigation to expand the surface chlorophyll time series.

Iron cycle

Iron is known to be a key limiting nutrient of ocean phytoplankton biomass. Yet, some aspects of its cycle remain unknown as the role played by the sediment particulate iron source (ANR BIIM).

Ocean / Seabed exchanges

The role of exchanges between ocean sediments and the water column remain crudely quantified on continental margins due to the lack of a clear understanding of the processes at play. We are developing approaches to study those processes and their integrated impacts on nutrients, dissolved oxygen and the carbon cycle.
