Projects

The Atlantic Meridional Overturning Circulation (AMOC) plays a key role on climate, by acting on the fluxes of heat, nutriments and salt all over the world.
Mission Hydrosed
The MD215 HYDROSED oceanographic campaign, conducted on board the Marion Dufresne, has allowed us to collect long marine sediment cores at sea water samples in the northern part of the South China Sea...
Mission Mingulay-Rockall
The project thus aims to conduct a multidisciplinary study based on these two sites (sedimentology, biology and geochemistry of corals) in order to reconstruct the growth history of these reefs as well as environmental changes...
Mission Monopol
The Indo-Asiatic monsoon is a major climatic phenomenon due to its economic and social impacts on one of the most densely populated regions of the world, and because of the scale of the heat and humidity transfers involved; in short, it is an essential element of the planet’s climate...
Measurements of CO2 trapped in Antarctic ice reveal that the pCO2 of the atmosphere during the Last Glacial Maximum (LGM) was 80 to 110 ppmv lower than the pCO2 value recorded for the interglacial period, before any anthropic activity...
The objectives of this research project fall within a study on the role of ocean circulation in the modalities of heat and salt transfer between low and high latitudes during the glacial-interglacial terminations...
The Southern Ocean (SO) and its circulation play a fundamental role in the global climate system. In fact, a key element of thermohaline circulation is the return route of water masses from the deep ocean to the surface via the dynamic of upwelling...
Our research aims to improve our knowledge of the hydrology of the Mediterranean and its European margin with a view to reconstructing the AMOC and thermohaline circulation in the Mediterranean during sapropel deposition events...
One of the principal approaches used to gain a better understanding of climatic sensitivity involves comparing past changes in ocean temperature with variations in greenhouse gases (GHG) recorded in ice...
Projet SEPORA
The Southern Ocean (SO) plays a fundamental role in the global climatic system. In fact, a key element in thermohaline circulation is the return route of water masses from the ocean depths to the surface via upwelling....
Lake Urmia is one of the largest salt-water lakes in the world. Since the1980s it has suffered severe environmental damage that has seen its level drop by 7 m over the past 15 years...
Laterites are deep weathering covers of the critical zone that occupy 80% of the total soil-mantle volume of the Earth’s landscape and significantly contribute to the global geochemical budget of weathering and erosion, and greenhouse gas consumption...
This project aims to test the various hydrological scenarios that have led to changes in the thermohaline circulation in the Mediterranean over the last glacial period and last deglaciation...
Since the 1950s, increasing CO2 emissions have amplified the natural greenhouse effect of the Earth, which is evident in a decrease in ice cover, a rise in sea level and the recurrence of extreme meteorological and climatic events...
Over the course of the Quaternary, variations in received insolation on the African continent have governed the dynamics of the Monsoon in this region causing a recurrence of intense periods of precipitation...
