New NASA map reveals hidden valleys beneath Greenland's ice

NASA's Earth Observatory has published a new map of the terrain beneath the Greenland Ice Sheet, showing hundreds of valleys that earlier maps missed or recorded only as fragments. The connected network of subglacial valleys reshapes how scientists understand water flow and ice dynamics under the ice, with implications for predicting how quickly Greenland may contribute to sea level rise.

Why now: The newly published NASA map offers an unprecedented, more complete view of the hidden landscape under the Greenland Ice Sheet, attracting attention from climate and science observers.
