Operation IceBridge, NASA’s longest-running airborne mission to monitor polar ice change, concluded this year’s springtime survey of Arctic sea and land ice on May 2. The flights, which began on March 22, covered the western basin of the Arctic Ocean and Greenland’s fastest-changing glaciers.

This image was taken during a research flight carried out on April 21 near Vestfjord Glacier in Scoresby Sund, along the eastern coast of Greenland. The photo shows a large iceberg that has broken the surrounding layer of consolidated sea ice. Flat floes of sea ice with fresh snow on top, areas of open water that are beginning to refreeze and neighboring smaller icebergs are visible.

The mission of Operation IceBridge is to collect data on changing polar land and sea ice and maintain continuity of measurements between NASA’s ICESat missions. The original ICESat mission launched in 2003 and ended in 2009, and its successor, ICESat-2, is scheduled for launch in September 2018. Operation IceBridge began in 2009 and is currently funded until 2020.
