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.

Crustaceans, snails, worms and fish are among the dozens of creatures that deep-sea explorers discovered under a massive Antarctic ice shelf.
