wo gravity cores, MB91/40 (53°04'S, 73°33'W; 451cm long) and MB91/54R (53°25'S, 72°54'W; 458.5cm long), have been recovered in the deeper and more inner basinal zone of the Western Magellan Strait in the framework of the marine geological research of the Programma Nazionale di Ricerche in Antartide. This work plans to identify the Late Quaternary changes through micropalaeontological data together with sedimentological data and their link to the climatic cycles. In particular, it highlights the value of the coccolithophore assemblages, never analysed before in the Strait of Magellan, and planktonic foraminifera in identifying the palaeoenvironmental and palaeoceanographic characteristics that influenced this area during the Holocene climatic evolution.
