A section of an iceberg – about 6,000 sq km – broke away as part of the natural cycle of iceberg calving off the Larsen-C ice shelf in Antarctica in this satellite image released by the European Space Agency on July 12, 2017. One of the biggest icebergs on record has broken away from Antarctica, scientists said on Wednesday, creating an extra hazard for ships around the continent as it breaks up. The one trillion tonne iceberg, measuring 5,800 square km, calved away from the Larsen C Ice Shelf in Antarctica sometime between July 10 and 12, said scientists at the University of Swansea and the British Antarctic Survey.
