Giant west Antarctic iceberg disintegrates
29 November 2017
An animation of the giant iceberg that calved off the Pine Island Glacier in West Antarctica just over two months ago shows an unexpected break up.
Satellite images revealed a 100-square-mile iceberg calving from Antarctica's Pine Island Glacier (PIG) in September. The calving event did not come as a complete surprise, but is a troubling sign for future sea-level rise. Scientists expected the iceberg to drift far out into the Southern Ocean before breaking up. However, it got stuck, probably impeded by thick sea ice, before it started to disintegrate into many smaller icebergs.
