Iceberg A-68 calved from the Larsen C Ice Shelf in July 2017. With a surface area of 5,800 square kilometres, it is one of the largest recorded icebergs, the largest being B-15 which measured 11,000 square kilometres before breaking up. There is no projected path at this point; however, historical data shows many icebergs broken off from the Antarctic Peninsula reach the South Georgia and the South Sandwich Islands.
The name "A-68" was assigned by the US National Ice Center.
A-68 was part of Larsen C, a section of the Larsen Ice Shelf. It broke away, due to warming ocean- and air-flows around the shelf. Scientists found the crack beginning to form in November 2016, and others suggested that it might have broken off as early as a decade ago.
