Pine Island Glacier is the fastest melting glacier in the world and its shelf extends into the Amundsen Sea – the location of several rapidly melting glaciers. Recent studies have shown that it is the ocean, rather than the atmosphere, that is melting this ice sheet from below. The water temperature in this area is a couple of degrees above freezing, and it is one of the only places around Antarctica where this warm water can get onto the shelf and all the way up to the ice.

The University of East Anglia use an underwater robot called a Seaglider to help collect data on this process. Louise Biddle will be presenting background on this area of study and also her own research on the ocean processes in the Amundsen Sea, using dissolved dissolved oxygen as a tracer for the meltwater that is produced.
