A large iceberg has recently separated from the calving front of Antarctica’s Pine Island Glacier. The January 2011 Landsat satellite imagery above shows a series of splits along the western edge of the glacier. The same area in January 2012 shows a major break, and theNovember 13, 2013, image shows that the new iceberg (Iceberg B-31) has broken off and is moving away from the coast. Pine Island is one of the largest and fastest-moving glaciers in Antarctica. 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. Iceberg B-31 is estimated to be 35 kilometers by 20 kilometers (21 by 12 miles), roughly the size of Singapore, about 50 percent larger than previous icebergs in this area.
