After breaking away from Pine Island Glacier, ice is set adrift in Pine Island Bay. The icebergs were visible from the DC-8 during the Operation Ice Bridge science flight on Oct. 20, 2009, to map the glacier.
Pine Island Glacier (PIG) is a large ice stream, and the fastest melting glacier in Antarctica. And being responsible for about 25% of Antarctica’s ice loss. Therefore glacier ice streams flow west-northwest along the south side of the Hudson Mountains into Pine Island Bay, Amundsen Sea, Antarctica.
The area drained by Pine Island Glacier comprises about 10% of the West Antarctic Ice Sheet. Satellite measurements have shown that the Pine Island Glacier Basin has a greater net contribution of ice to the sea than any other ice drainage basin in the world and this has increased due to recent acceleration of the ice stream.
