Larsen Ice Shelf |
Also found in: Wikipedia | 0.04 sec. |
Larsen Ice ShelfIce shelf in the northwestern Weddell Sea, adjoining the eastern coast of the Antarctic Peninsula. It is named for Capt. Carl A. Larsen, who explored the ice front by boat in 1893. The shelf originally covered an area of 33,000 sq mi (86,000 sq km), excluding the numerous small islands within it, but, as air temperatures over the Antarctic Peninsula warmed slightly in the second half of the 20th century, the shelf shrank dramatically. By the early 21st century, it covered only 40 percent of its former area. How to thank TFD for its existence?

A team of scientists last year predicted that the entire Larsen B shelf would rapidly disintegrate once its front edge retreated behind a theoretical line of stability--an event that happened in February 1998 (SN: 5/9/98, p. The recent loss may cause the entire Larsen B shelf, which covers more than 10,000 square km, to crumble in the next year or two, says Scambos. |
