Mysterious New Crack in Greenland Glacier Revealed in NASA Photos
By Kacey Deamer, Staff Writer | April 17, 2017 06:08pm ET
There is a new crack in one of Greenland's largest glaciers, and NASA researchers have captured the first images of the ice shelf's mysterious rift.
Operation IceBridge, NASA's airborne survey of polar ice, recently completed a land-ice mission over northwest Greenland. During the mission, researchers flew over and photographed a new rift near the center of Petermann Glacier's ice shelf (the floating end of the glacier). In the survey photos, the new rift appears relatively close to a larger, known crack that is spreading toward the center of the ice shelf. [Images: Greenland's Gorgeous Glaciers]

Coukd very well be from tafting..warmer water coming in under the glacier, melting and lubricating the bed. If so, this could result in a lot of ice movement.
