The world’s largest iceberg is on the move again, drifting through the Southern Ocean after months stuck spinning on the same spot, scientists from the British Antarctic Survey (BAS) have said.

Traffic in the vicinity of Antarctica has become a bit trickier now that A23a, the world's oldest and largest iceberg, has broken free of its watery trap north of the South Orkney Islands and is floating northward on the Antarctic Circumpolar Current.

Picture the sprawling city of Los Angeles. Then triple that size. That’s about the magnitude of the world’s largest iceberg, aka A23a, clocking in at 1,418-square-miles and a whopping one trillion tons.
