A black and white aerial view of Pine Island Glacier Ice Shelf shows its heavily crevassed surface. Pine Island Glacier, also known as PIG, is one of the fastest receding glaciers in the Antarctic and one of the main contributors to rising sea levels. The ice shelf that fronts the glacier is thinning, which allows the glacier to move toward the sea faster. A team of scientists visited the region during the 2012-13 field season to send instruments through the ice shelf to see how the water below may be thinning the ice.
