Description :
Modelling studies of underside of Brunt and Ross ice shelves suggest two main conclusions: 1. Ice-shelves are of major importance for sedimentation on the continental shelf. Bulk debris release occurs within the grounding-line zone which may frequently oscillate, producing pronounced diachronism. Bottom melting removes all debris prior to calving at the ice front so that, ice shelves do not play a part in deposition in the open ocean| 2. Outlet glaciers, in contrast, have high sediment content, calve rapidly and produce debris-rich icebergs which contribute the major portion of ice-rafted debris.
