Last week, the BAS released Bedmap3, "the most detailed map yet" of Antarctica's landscape beneath its blanket of ice, a press release about the map said. Scientists used data from planes, satellites, ships, and dog sleds to create the map and then published the results on March 12 in the Scientific Data journal.

Bedmap3 is the most fine-grain map to date of the landscape beneath Antarctica's ice. Scientists created it using more than 60 years' worth of data from satellites, ships and dog-drawn sleds.
