(Phys.org)—A team of researchers working with NASA's Operation IceBridge has snapped a picture of a crack in the middle part of Petermann Glacier—it resides on Greenland's northern coast. The photo and other accompanying ...
For the past eight years, Operation IceBridge, a NASA mission that conducts aerial surveys of polar ice, has produced unprecedented three-dimensional views of Arctic and Antarctic ice sheets, providing scientists with valuable ...
