A massive iceberg shattered off one in all West Antarctica’s largest glaciers last year, and now, scientists have discovered the “troubling” reason why, they said.

In 2015, associate degree iceberg measure virtually 225 sq. miles (580 sq. kilometers) stony-broke removed from the Pine Island ice mass, that forms a part of the ice that bounds the West Antarctic Ice Sheet. Recently, whereas reviewing satellite pictures taken before the enormous iceberg stony-broke off, researchers found proof of a rift at the terribly base of the ice. This implies that the sprawling ice mass stony-broke with the exception of the within out, the new study aforesaid.

The base rift was situated nearly twenty miles (30 km) upcountry, and will 1st be seen in satellite pictures from 2013, the researchers aforesaid. Viewing satellite pictures taken before the 2015 fracture, the scientists discovered that the rift unfold upward for 2 years before breaking through the ice surface. The iceberg was then set adrift over twelve days in late July and early August 2015, the scientists value-added.

The means the Pine Island ice mass stony-broke with the exception of the within out could be a sign that the ice sheet remains melting, aforesaid Ian Howat, a glaciologist at The Ohio State University and lead author of the new study.
