New Maps Show Off Greenland's Ice In Unprecedented Detail
The radar maps could help scientists understand Greenland's environment as it was 115,000 years ago and predict its behavior in the future.By Evan Thomas | January 23, 2015
Ice is not just frozen water. In Greenland, there are thousands of years of history locked up in layers of the stuff.
Thanks to new radar maps of Greenland’s ice sheet, scientists are getting their best picture yet of what the ice was like a long time ago.
The maps use data gathered in early 2014 by NASA’s annual Icebridge mission, which flew ice-penetrating radar over Greenland’s glaciers.
