Iceberg B-15 was the largest recorded iceberg by area. It measured around 295 by 37 kilometres (159 by 20 nautical miles), with a surface area of 11,000 square kilometres (3,200 square nautical miles), about the size of the island of Jamaica. Calved from the Ross Ice Shelf of Antarctica in March 2000, Iceberg B-15 broke up into smaller icebergs, the largest of which was named Iceberg B-15A. In 2003, B-15A drifted away from Ross Island into the Ross Sea and headed north, eventually breaking up into several smaller icebergs in October 2005. In 2018, a large piece of the original iceberg was steadily moving northward, located between the Falkland Islands and the island of South Georgia. As of August 2023, the U.S. National Ice Center (USNIC) still listed one extant piece of B-15 that meets the minimum threshold for tracking (70 km2 or 20 sq nmi). This iceberg, B-15AB, measured 20 km × 7 km (11 nmi × 4 nmi); it was, as of 2021, grounded off the coast of Antarctica in the western sector of the Amery region.
