SCAN-2013_CODEREC Cruise (29HE20130202) carried out on the Research Vessel Hespérides in 2013 SCAN 2013 ( SCotia-ANtarctic) & 'Lithological and chronostratigraphic study of recent sedimentary units of Puerto Foster (Deception Island, Antarctica), COREDEC ' During the 2013 SCAN cruise, two basic objectives related to the evolution of the Western Antarctica: (a) plate tectonics and the development of ocean basins in the Scotia Sea and Straits of Brandsfield, and (b) the paleoceanographic processes that were derived from the establishment of the Circumpolar Current Antarctic (ACC) after the opening of the Drake Passage and the development of Antarctic Deep Water, with its implications and possible contribution to global change. High resolution (SAR) seismic reflection profiles, very high resolution seismic profiles have been made using the TOPAS system, EM 120 multibeam echo sounder, magnetometry and gravimetry in the Scotia Sea and Strait of Brandsfield. 17 SAR profiles have been obtained, with all operating systems with a total of 2679.4 km. They have made a total of 47 lines with TOPAS, MAG and GRAV, along a route of 5,025 km. They have dredged, in addition, 5 morphological reliefs and 3 gravity witnesses have been taken in 1 high with outcropping series. The dredges carried out have provided excellent quality samples of the igneous and metamorphic basement of the Scotia Sea. The objective of CODEREC has been to obtain Seven sediment cores from the inner bay of Deception Island
