On July 12, a giant iceberg was born as a chunk some 6,000 km2 (2,300 mi2) broke away from the Larsen C ice shelf in Antarctica. The breakup was the result of an 18-month suspense story, as scientists watched the crack extend across the ice. But with the berg now adrift and satellites continuing to monitor the site, it seems the saga isn’t over yet: the remaining cracks are spreading towards a feature that’s integral to the stability of the rest of the ice shelf.
