An enormous Antarctic glacier has given up an iceberg over 100 square miles in size, the second time in two years it has lost such a large piece in a process that has scientists wondering if its behavior is changing for the worse.
NASA has lately spotted a gigantic iceberg in Antarctica, identified as B31 and together with UK's BAS (British Antarctic Survey), is busy tracking the monster island of ice, which has now escaped into open waters. Despite its sheer size and mass, --experts estimate that the giant iceberg is approximately 600 square kilometres in size--, monitoring is not going to be an easy task with the coming of the Antarctic winter and ensuing darkness.
An Iceberg, the size of Manhattan in area, was derived from the Pine Island Glacier, and is currently moving through the Southern Ocean. To keep track of its movements and melting Professor Grant Bigg of UK's University of Sheffield has been awarded a £50,000 grant from the Natural Environment Research Council (NERC) for the 6 month project.
Pine Island Glacier (PIG), the longest and fastest flowing glacier in the Antarctic, has spawned a huge iceberg. The block measures about 720 sq km in area - roughly eight times the size of Manhattan Island in New York.
Scientists and flight crew members with Operation IceBridge, NASA's airborne mission to study Earth's changing polar ice have started another campaign over Antarctica. Now in its fourth year, IceBridge's return to the Antarctic comes almost a year after the discovery of a large rift in the continent's Pine Island Glacier.
A massive crack is growing wider in the Antarctic ice sheet and could break apart in the coming months, forming an iceberg the size of the island of Lanzarote (Canary Islands, Spain), NASA scientists warned Thursday.
