👀 The world’s largest iceberg has continued its path north across the Southern Ocean, imagery from CIRA shows, after moving into open water in late 2023. Known as A23a, the near-trillion-ton ice mass had been grounded on the sea floor for decades since calving from the Filchner Ice Shelf in August 1986, according to the British Antarctic Survey. This CIRA timelapse shows the iceberg passing to the north of the South Orkney islands, in the Southern Ocean’s Weddell Sea, during March. #Iceberg #A2
