A pencil-shaped robot is giving scientists their first look at the forces eating away at the Thwaites glacier in Antarctica
has gotten the nickname the"Doomsday Glacier" because of how much ice it has and how much seas could rise if it all melts — more than 2 feet , though that's expected take hundreds of years.
Pennsylvania State University glaciologist Richard Alley, who also wasn’t part of the studies, said the new work"gives us an important look at processes affecting the crevasses that might eventually break and cause loss of much of the ice shelf.” And more bad news: This is from the eastern, larger and more stable part of Thwaites. Researchers couldn’t safely land a plane and drill a hole in the ice in the main trunk, which is breaking up much faster. And they also found staircase-like steps, those crevasses, in parts of the more stable eastern side where the break-up is far faster and worse.
Ted Scambos of the National Snow and Ice Data Center, who wasn’t part of the studies, said the results add to understanding how Thwaites is diminishing.
