Session 7: Marine sediments: from depositional processes to paleoceanographic reconstructions

Coordination: Aurélie Penaud (Geo-Ocean), Samuel Toucanne (Geo-Ocean), Natalia Vazquez Riveiros (Geo-Ocean)

Keywords: paleoceanography, paleoclimate, paleoproductivity, paleotemperature, proxies (sedimentology, micropaleontology, palynology, isotopic geochemistry, biomarkers), forcing, Pleistocene, Holocene, abrupt climate changes

This session will focus on marine sedimentology with a particular focus on the paleoenvironment, in order to gain a better understanding of the dynamics of climate, ocean and biogeochemical cycles, as well as their interactions. From a methodological perspective, research on facies and sedimentological processes, as well as geochemical and paleoecological analyses aiming to characterize the environmental responses (marine currents, sedimentation and ecosystems) to different forcings, rapid climate variability during past climates, or extreme/abrupt events, are expected. Multi-proxy approaches and data-model comparisons on global to regional scales are encouraged. Paleoceanographic proxy calibration or general hydrological and climatic paleoquantifications are also of interest. The primary aim of this session is to disseminate recent advances on the understanding of paleoceanographic proxies among the Quaternary community. These studies will allow the characterization of past natural climate trajectories from which anthropogenic forcing is inexorably pushing us away.
