Abstract | SEDANO Project aim to understand the origin of the glacial depositional systems found offshore the Pacific margin of the Antarctic Peninsula. Four main glacial depositional systems have been identified. Geophysical surveys were carried out during these two projects The cores collected in this area characterise the sediment drifts as composed by fine-grained, poorly-sorted sediments, sourced from turbidity currents generated on the continental slope. To elucidate the role of dispersal and redistribution of sediments by bottom currents, three one-year long bottom current records in the area of the mound 7 were collected as well as nine CTD measurements collected in the same area . It is worthwhile noting the importance of this data set, constituting the first current measurements available in the Pacific margin of the Antarctic Peninsula. The aim of this work threefold: to infer which are the major large scale processes that govern bottom current regime, to understand the Bottom Boundary Layer (BBL) dynamics, and to assess the potential for resuspension induced by the measured currents. |
