NASA has released an updated map of the bedrock beneath the Antarctic ice sheet; the map, called Bedmap2, adds considerable detail — a tighter grid and millions of data points — to its decade-old predecessor. The image above exaggerates vertical scale by a factor of 17 to increase visibility. See also this short video. Image credit: NASA-GSFC.
