As part of the International Polar Year project "Ocean-Ice Interaction in the Amundsen Sea: the Keystone to Ice-Sheet Stability", the National Science Foundation's Office of Polar Programs has funded an investigation of the ocean circulation and ocean-ice interaction in the seawater-filled cavity below Antarctica's Pine Island Glacier. A sophisticated, profiling ocean sensor package is currently being developed to provide new observations of the role of the ocean in melting the underside of the glacier.
