Flying through the Rift: An update on the crack in the P.I.G.
on March 6, 2012
NASA's DC-8 flew over the Pine Island Glacier Ice Shelf on Oct. 14, 2011, as part of Operation IceBridge. A large, long-running crack was plainly visible across the ice shelf. The DC-8 took off on Oct. 26, 2011, to collect more data on the ice shelf and the crack. The area beyond the crack that could calve in the coming months covers about 310 square miles (800 sq. km).
