What lies beneath? BedMachine: Scientists create a high-precision map of Antarctic ice sheet bed topography.
NASA on September 15, will launch a laser satellite to scan Earth’s ice sheets, in amazing accuracy.
Small valleys near the top of Antarctica’s ice sheet reach temperatures of nearly -100 degrees Celsius.
Greenland’s ice layers are now mapped in 3D, thanks to NASA’s Operation IceBridge. Peering into the frozen layers inside ice sheet, is like looking back in time.
