Summer Melt on Greenland Ice Sheet

NASA’s IceBridge Observes Effects of Summer Melt on Greenland Ice Sheet

NASA’s IceBridge, an airborne survey of polar ice, flew over the Helheim/Kangerdlugssuaq region of Greenland on Sept. 11, 2016.

The IceBridge flights, which began on Aug. 27, are mostly repeats of lines that the team flew in early May, so that scientists can observe changes in ice elevation between the spring and late summer. For this short, end-of-summer campaign, the IceBridge scientists flew aboard an HU-25A Guardian aircraft from NASA’s Langley Research Center in Hampton, Virginia.
