The ice bridge holding the Wilkins Ice Shelf to the Antarctic coastline and Charcot Island was 40 kilometres (25 mi) long but only 500 metres (1,640 ft) wide at its narrowest point – in 1950 it was 100 kilometres (62 mi) It shattered in April 2009 over an area measuring 20.1 by 2.4 kilometres (12.5 by 1.5 mi). The ice bridge collapsed rapidly ...

These animations show the motion of ice in Antarctica. Velocity map of Antarctica. Ice streams can be seen with increasing speeds (blue-yellow-white) flowing toward the coast. [1] Radarsat image of ice streams flowing into the Filchner-Ronne Ice Shelf. An ice stream is a region of fast-moving ice within an ice sheet.
Massive chunks of Argentina's Perito Moreno Glacier, which is known as the "White Giant," collapsed into the water on Thursday as tourists and locals watched from an observation deck.
