Project MIDAS, a UK-based group that studies the Larsen Ice Shelf, reported in August 2016 that a large crack in Larsen C had grown by another 22 kilometres (13 miles) in six months. The crack was then more than 130 kilometres (80 miles) long.
Larsen C is Antarctica’s fourth-largest ice shelf, covering about 50,000 square kilometres. The group’s computer modelling predicted that the crack would keep growing and break away 9 to 12 percent of the shelf, about 6,000 square kilometres of ice. Its neighbours, Larsen A and Larsen B, collapsed in 1995 and 2002.
Images taken by the MISR instrument on NASA’s Terra satellite on 22 August 2016 showed the crack as rougher than the ice around it, a sign that it was actively growing.
