Today’s Video of the Day from the National Science Foundation describes research in Greenland that has revealed that the massive ice sheet is sliding more than what was previously realized.
A team from the University of Wyoming and the University of Montana has made the surprising discovery that the ice slides across hard bedrock all winter long.
Bedrock is a surface that was not expected to allow ice to shift so easily, especially in the winter.
The phenomenon is moving ice from a higher elevation to a lower elevation, where it is more likely to get dumped in the ocean.
