Unique Stretch Marks Show
Greenland Ice Accelerating Toward Sea

Crevassing in Greenland ice
The Greenland ice sheet is accelerating as it flows toward the ocean, and the unique markings visible in this photograph are one piece of evidence
demonstrating its rapid movement. Captured as part of NASA's Operation IceBridge
, which is wrapping up its seventh season of Arctic observations, this image details heavy crevassing near the coast of Melville Bay in northwestern Greenland. These fissures are essentially stretch marks on the ice, NASA researchers say. Ice sheets in Greenland and Antarctica are losing mass at an unprecedented rate of 500 cubic kilometers per year — enough ice to cover the Chicago metropolitan area with a layer of ice 600 meters thick — according to
one recent report. Greenland's ice volume alone is shrinking by about 375 cubic kilometers per year, with the loss doubling since 2009, the study found.
