World’s largest iceberg breaks into smaller chunks near South Georgia

Iceberg A68, once one of the largest recorded, has broken into several chunks, including A68D, A68E, and A68F. These icebergs are being monitored as they drift near South Georgia, posing potential threats to local wildlife. Satellite images have tracked their movements, and ongoing analysis shows the iceberg's keel is thinning, which may have contributed to its breakup.
