Marine Biogeochemistry, Atmosphere and Climate

Gaining knowledge on the role of the marine biosphere in climate and global environmental change

Our research addresses the central role of the marine biosphere in the cycling of elements (mainly C, N and S) in the oceans and across the ocean-atmosphere boundary in the context of global environmental change. Both benthic and pelagic ecosystems are considered as drivers and receptors of climate and biogeochemical changes, and the ecophysiological bases of their responses are addressed. The main research topics are ocean acidification and warming, paleoceanography, ecology of benthic communities, chemical communication, organic matter biogeochemistry, plastic pollution, air-sea exchanges, and biogenic aerosols and their effects on clouds. Ours is a multi-scale perspective both through time (past, present and future), space (local to global), and completeness (molecules to biosphere). Tools include chemical, isotopic and microscopic analyses, molecular biology, time series and oceanographic studies, lab manipulations, global databases, autonomous platforms, and numerical models.
