The area west of the Antarctic Peninsula is a key region for studying and understanding the history of glaciation in the southern high latitudes during the Neogene with respect to variations of the western Antarctic continental ice sheet, variable sea-ice cover, induced eustatic sea level change, as well as consequences for the global climatic system (Barker, Camerlenghi, Acton, et al., 1999). Sites 1095, 1096, and 1101 were drilled on sediment drifts forming the continental rise to examine the nature and composition of sediments deposited under the influence of the Antarctic Peninsula ice sheet, which has repeatedly advanced to the shelf edge and subsequently released glacially eroded material on the continental shelf and slope (Barker et al., 1999). Mass gravity processes on the slope are responsible for downslope sediment transport by turbidity currents within a channel system between the drifts. Furthermore, bottom currents redistribute the sediments, which leads to final build up of drift bodies ... : Supplement to: Wolf-Welling, Thomas C W; Moerz, Tobias; Hillenbrand, Claus-Dieter; Pudsey, Carol J; Cowan, Ellen A (2001): Data report: Bulk sediment parameters (CaCO3, TOC, and >63 mym) of Sites 1095, 1096, and 1101, and coarse-fraction analysis of Site 1095 (ODP Leg 178, western Antarctic Peninsula).
