Water isotopes are one of the most widely used proxies in ocean climate research. However, there are still gaps in our understanding of the processes that control their composition. Compared to other large ocean basins, the Mediterranean is ideally suited to improve our understanding of the processes influencing and driving oxygen isotopic...

The response of eastern Mediterranean Sea (EMS) circulation to climate forcings over the last 95 kyr BP was studied using core MD04-2722, collected at 1780 m water depth within the Levantine Sea. Foraminiferal stable isotopes and benthic assemblages were combined in order to reconstruct deep water ventilation and oxygenation in relation to...

The Eastern Mediterranean Sea (EMS) is a key region to study circulation change because of its own thermohaline circulation. In this study, we focused on intermediate/deep water circulation since the Last Glacial Maximum (LGM) including the sapropel S1 period. Two cores from the Levantine Sea and the Strait of Sicily, respectively, collected at...

A 144-cm-long core was obtained in Lake Petit (2200 m a.s.l., Mediterranean French Alps) in order to reconstruct past interactions between humans, the environment and the climate over the last five millennia using a multidisciplinary approach involving sedimentological, geochemical and botanical analyses. We show a complex pattern of...

Mediterranean mountains are very sensitive geosystems to erosion processes. These environments combine three steep gradients: topographic, ecologic and climatic. They are extremely vulnerable to both anthropogenic and climate-driven global changes. We propose a multiproxy approach from sediments sequence of Petit Lake (2200m, Millefonts...
