Summary
Abstract: Ocean circulation beneath ice shelves and associated rates of melting and freezing are influenced strongly by water column thickness and depth. The shape of the cavity beneath the Amery Ice Shelf is important for our understanding of ice shelf stability and freshwater input to the ocean and their dependence on climate. New seismic surveys of the centre region of the Amery Ice Shelf and ice-draft ... View entire text
