An Iceberg Is Born

Over the course of two years, NASA satellites and airborne instruments tracked the birth of a new iceberg from Pine Island Glacier, the longest and fastest-moving glacier in West Antarctica. Scientists first discovered a large crack while flying over the glacier in October 2011. By July 2013, satellite images indicated that the crack had cut completely across the ice shelf to the southwestern edge, forming a chunk of ice about 21 miles wide and 12 miles long. New images now show that the iceberg, named B-31, is slowly moving away from the coast. Watch the video to see the iceberg separate from Pine Island Glacier.
