Short summary
This study combines a variety of geophysical measurements in front of and beneath the Ekström Ice Shelf in order to identify and interpret geomorphological evidences of past ice sheet flow, extent and retreat. The maximal extent of grounded ice in this region was 11 km away from the continental shelf break. The thickness of palaeo-ice on the calving front around the LGM was estimated to be at least 305 to 320 m. We provide essential boundary conditions for palaeo-ice-sheet models.
