Depleting glacier was a common phenomenon for NASA scientists working in Antarctica, but in mid- October 2011, they were shocked to discover a massive crack across the Pine Island Glacier. It was like a scene straight out of a science- fiction disaster movie. The crack (featured in the image as base layer) was captured by Terra satellite on November 13, 2011. Recently, using data gathered by NASA’s Operation IceBridge science flight team, the agency generated a 3D fly through of the crack (featured as a top layer on the image). The crack extends for 19 miles (30 kilometres), is 260 feet (80 metres) wide and 195 feet (60 metres) deep. They claim that eventually, it will extend all the way across the glacier and calve a giant iceberg that will cover about 350 square miles (900 square kilometres). Pine Island is one of the largest and fastest moving glaciers in Antarctica and the crack has made climate scientists concerned.
