Laboratoire de Planetologie et Geodynamique de Nantes
Our projects focus on modern benthic and planktic marine ecosystems, and a better understanding of the formation of fossil assemblages. Analyses of planktic foraminifer production, ecology, and particle fluxes in the water column are targeted towards quantification of the transfer of carbon (e.g., CO2 budget) from the surface to the deep ocean (biological carbon pump). Ecological studies of benthic foraminifer assemblages focus on high-productivity and low-oxygen conditions as, for example, upwelling areas, submarine canyons, eutrophic shelf seas. In those areas we analyse and quantify 1) the flux of organic matter to the sea floor, 2) bottom water oxygenation, 3) redox conditions in surface sediments, and the 4) temporal variability of sea floor environments.

Call for Climate Services Collaborative Research action on Climate Predictability and Inter-regional Linkages
Climate Services aim at providing more reliable climate information for the near future (months to decades) relevant for local and regional users. Within this broad context, variability of polar and tropical systems affects a large proportion of the world population. This call with the Belmont Forum aimed to contribute to the overall challenge of developing climate services with a focus on inter-regional linkages role in climate variability and predictability. Eight multi-national projects have been selected for funding through this call.
