The voyage of Iceberg B-31 continued in January, 2014 as the giant iceberg drifted over the frigid waters of Pine Island Bay and widened the gap between the newly-calved iceberg and the “mother” glacier.

Between November 9 and 11, 20143 a giant crack in the Pine Island Glacier gave completely away, liberating Iceberg B-31 from the end of the glacial tongue. The new iceberg was estimated to be 35 km by 20 km (21 mi by 12 mi) in size – or roughly the size of Singapore.

On January 5, 2014 the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite captured this true-color image of B-31 floating in the center of Pine Island Bay on an approach to the Amundsen Sea. Pine Island Glacier can be seen on the upper right coast of the bay, and is marked by parallel lines in the ice. According to measurements reported by the National U.S. Ice Center, on January 10, B-31 was maintaining its size, and was located at 74°24'S and 104°33'W.
