With the robot named Icefin lowered down a slender 1,925-foot (587-meter) hole, they saw how important crevasses are in the fracturing of the ice.

The Florida-sized glacier got its nickname because of how much ice it has and how much seas could rise if it all melts.

The "Doomsday Glacier" could cause global sea levels to rise by more than half a meter if it melts. But scientists examining erosion say there is good news and bad news.

Using a 13-foot pencil-shaped robot that swam under the grounding line where ice first juts over the sea, scientists saw a shimmery critical point in Thwaites’ chaotic breakup, “where it’s melting so quickly there, there’s just material streaming out of the glacier.”
