Between November 9–11, 2013, a large iceberg separated from the calving front of Antarctica’s Pine Island Glacier. Scientists first detected a rift in the glacier in October 2011. By July 2013, infrared and radar images showed that the crack had cut completely across the ice shelf. New satellite images now show that Iceberg B-31 is finally moving away from the coast.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired these natural color images of Pine Island Glacier on November 10 (top) and November 3, 2013. Dubbed B-31 by the U.S. National Ice Center, the new iceberg is estimated to be 35 kilometers by 20 kilometers (21 by 12 miles), roughly the size of Singapore. A team of scientists from Sheffield and Southampton universities will track the 700 square-kilometer chunk of ice and try to predict its path using satellite data.
