Objective The PRIMAROSA SUD 1 (Paleoclimatic Research In Mediterranean Atlantic Record Overflow Sedimentary Activity) program is included in the MD140/PRIVILEGE survey (French acronym: Program Intégré Valorisé par l'IFREMER, le LSCE, l'EPOC en GÉologie). Late Quaternary paleoclimatic variability, Ocean-Continent relationship. The PRIMAROSA program has 2 main strands, one focusing on paleoclimatology and the other on identifying deep bodies. This involves looking for climate variability over the past 450,000 years with a particular focus on comparing the evolution of the current Holocene interglacial period and that of the closest analogue, "astronomically speaking", ie the Holsteinian (isotope 11 stage). The ability to predict future climate changes will require knowledge of the climate's natural variability in the past, over several glacial-interglacial cycles, and with high resolution over the last 10,000 years. It is therefore essential to pursue the highly multidisciplinary studies based on the high variability of biological, sedimentological and geochemical tracers on long-term sedimentary series (CALYPSO cores) or on those corresponding to recent sedimentation (CASQ cores). The paleoclimatic strand is also addressed via the deep sedimentary systems in the gulf of Cadiz. This area effectively corresponds reductive structures being built on the bottom which are related to the variability of deep flows from the Mediterranean via Gibraltar. This variability is related to environment changes in surface and bottom water masses and with the continental climate environment (wind conditions).
