International audience The purpose of this study is to characterize palaeoceanographic variations induced by climate changes on the glacial-interglacial time scale. The climatic control of terrigenous clay mineral sedimentation depends on latitudinal and longitudinal distribution of the sediments investigated (Bout-Roumazeilles et al., 1997). The climatic variations affect the intensity of both physical and chemical weathering on the continent and, the transport of clay minerals by wind and marine currents. Clay particules, less than 2 microns, from a series of ODP cores and piston cores from various geographical settings in the North Atlantic and Arctic Oceans, will be used as palaeoceanographic
