GREENBELT, Md., June 5 (UPI) -- NASA says data from several missions has helped create a map of Antarctica giving a clearer picture of the continent from the ice surface to the bedrock below.
The new dataset called Bedmap2 is the result of work led by the British Antarctic Survey, whose researchers compiled decades worth of geophysical measurements such as surface elevation measurements from NASA's Ice, Cloud and Land Elevation Satellite, or ICESat, and ice thickness data collected by aircraft in Operation IceBridge, the space agency reported Wednesday.
