Often, such chunks keep the place they’re, like the marginally bigger A23a, which remains to be in Antarctica’s Weddell Sea after breaking off, or calving, from the Filchner Ronne Ice Shelf. By distinction, some, like A68a, are whisked north on the fast-running Southern Antarctic Circumpolar Current Front, often breaking apart into smaller chunks that scientists name “bergy bits” or

The white arrows in (a) and (e) indicate further interesting features. The iceberg came from a part of the Antarctic where it is still very cold - the Larsen C Ice Shelf.

The record for the largest current iceberg changed hands in December 2020 when the previous record holder (A68A) broke into several fragments as it got perilously close to the island of South Georgia in the South Atlantic. The title now passes to A23A, which is much … The iceberg A23A (A23A) in the Weddell Sea, the Four‐Ladies Bank (FB) in the Prydz Bay, and the Iselin Bank (IB) and Oats Land (OL) are also shown as reference in the maps.
