I want to know the answer to the following question:
What Antarctic ice shelf collapsed in 2008?
All the background I'm provided with is that "Between 28 February and 8 March 2008, about 570 km2 (220 sq mi) of ice from the Wilkins Ice Shelf on the southwest part of the peninsula collapsed, putting the remaining 15,000 km2 (5,800 sq mi) of the ice shelf at risk.". Is that enough to answer the question?
