Hidden Valleys Beneath Greenland's Ice Sheet Revealed

Original: Uncovering the Valleys Hidden Below Greenland’s Ice

NASA scientists are mapping vast hidden valleys buried beneath Greenland's ice sheet, using radar and other remote-sensing techniques to reveal the dramatic landscape below. The work helps researchers understand how meltwater drains under the ice and how this may influence ice sheet behaviour and sea-level rise. The findings highlight how much of Greenland's geography remains unseen beneath kilometres of ice.

Why now: Ongoing NASA research into Greenland's subglacial terrain has drawn fresh attention amid concerns about ice melt and sea-level rise.
