Presentation

I am a marine biogeochemist with a general research interest on nutrient cycling at the surface ocean and at the ocean-atmosphere interface. I am particularly interested on the oligotrophic ocean where nutrient scarcity limits biological activity and, thus, carbon export is highly dependent on nutrient availability. So far, I have broadly focused my research activities on the potential links between dust deposition and phosphorus (P) cycle in the surface ocean. More recently, I am using high-sensitive techniques to measure phosphate concentration in seawater in order to gain further insight of the P cycle in the surface ocean, particularly concerning the bioavailability of the organic pool.
Mes recherches portent, d’un point de vue général, sur les cycles biogéochimiques des nutriments dans l’océan de surface et à l’interface océan-atmosphère. J’ai un intérêt tout particulier pour l’océan oligotrophe où la carence en nutriments limite l’activité biologique et, de ce fait, l’export de carbone est largement dépendant de la disponibilité en nutriments. Jusque-là, j’ai largement focalisé mes travaux de recherche sur les liens potentiels entre le dépôt de poussières désertiques et le cycle du phosphore (P) dans la couche océanique de surface. Plus récemment, j’utilise des techniques sensibles de mesure de la concentration en phosphate dans l’eau de mer dans le but de mieux comprendre le cycle du P dans l’océan de surface, notamment en ce qui concerne la biodisponibilité du réservoir organique.
