» Coastal physical oceanography

In the frame, for example, of the EPIGRAM program, we explore the physical dynamics over the shelf in the Bay of Biscay.

» Tropical Atlantic physical dynamics

In the frame of the PIRATA program, the interannual variability of sea level anomalies in the Gulf of Guinea is analysed using São Tomé island tige gauge data, satellite altimetry and PIRATA mooring data.

» Rossby waves and biogeochemistry

Even if the ocean represents less than 1% of the biomass, it drives around half of the net biosphere photosynthesis. This biomass plays consequently a key role in the climate regulation through, for example, the oceanic carbon cycle. It is then necessary to estimate accurately this biomass as well as its associated processes.

My research work aims to better understand the oceanic interaction between the physics and the biogeochemistry. In particular, I'm studying the influence of wave processes as:

» The Rossby waves or planetary waves
(you can find more details in my publications and personal communications)

» Importance of Dissolved Organic Nitrogen in the North Atlantic Ocean

The study of the nitrogen cycle in the North Atlantic subtropical gyre represents another of my research topics. Indeed, the origins of the biogeochemical productions in this oceanic «desert» are poorly known and seem driven by the meridional supply of dissolved organic matters (nitrogen and phosphorus).
