Pine Island Glacier Retreat, Antarctica

Pine Island Glacier is a large ice stream, and the fastest thinning glacier in Antarctica, responsible for about 25% of Antarctica's ice loss. 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 global ocean than any other ice drainage basin in the world and this has increased due to recent acceleration of the ice stream.



These visualizations show the advance and retreat of the front of this ~35-kilometer (~22-mile) wide outlet glacier. The flow of inland ice causes the glacier’s front to advance and multiple calving events cause the front to retreat. The glacier’s ice front has retreated ~25 kilometers (~15 miles) since 2000. Combined, the 2015 and 2017 calving events have led to the glacier’s ice front being fully disconnected from the North Ice Shelf. The changes to this large outlet from West Antarctica could signal additional sea level contributions from this glacier and the even larger outlet to the west, Thwaites Glacier.
