“Hot” news from the Antarctic: another ice sheet is breaking up. The Wilkins Ice Shelf, a 13,680 square kilometre ice shelf on the SW coast of the Antarctic Peninsula, began to break up at the end of February. From the NSIDC release:
Satellite images indicate that the Wilkins began its collapse on February 28; data revealed that a large iceberg, 41 by 2.5 kilometers (25.5 by 1.5 miles), fell away from the ice shelf’s southwestern front, triggering a runaway disintegration of 405 square kilometers (160 square miles) of the shelf interior (Figure 1)
Here’s Figure 1:
The British Antarctic Survey flew their Twin Otter aircraft over the collapsing ice shelf. The video it took (available here) is truly amazing.
