Multibeam swath bathymetric data and sub-bottom acoustic profiles collected during RRS James Clark Ross Cruise JR104 revealed the existence of a major glacial trough (Belgica Trough) on the West Antarctic continental shelf in the southern Bellingshausen Sea (75°-90°W, 69°-73°S), and of a trough mouth fan on the adjacent slope. Distinct seabed morphological features, such as mega-scale glacial lineations, drumlins and grounding-zone wedges, indicate that Belgica Trough represents the former pathway of a grounded ice stream, which had advanced to the shelf break during the last glacial maximum (LGM). Moreover, the orientation of the subglacial bedforms suggests that the ice stream was fed by grounded ice draining both through Eltanin Bay and ...
