Crack in Antarctica’s Larsen C ice shelf forks
Science News, May 2017The 180-kilometer-long crack threatening one of Antarctica’s largest ice shelves has branched out, new satellite observations reveal. The main rift in the Larsen C ice shelf hasn’t grown longer since February. But radar mapping shows that a second crack has split off from the main rupture like a snake’s forked tongue, members of the Antarctic research group Project MIDAS reported May 1. That second branch, which stretches around 15 kilometers, didn’t exist on radar maps taken six days earlier, the scientists say.
