A23a: World's biggest iceberg on the move after 30 years

The world's largest iceberg, A23a, is now moving for the first time in over three decades, drifting past the northern tip of the Antarctic Peninsula.
This iceberg, weighing nearly a trillion metric tonnes, is expected to be launched into the Antarctic Circumpolar Current and move towards the Southern Ocean, where it could disrupt shipping.
The movement of A23a is believed to be due to shrinkage and increased buoyancy, allowing it to lift off the ocean floor and be pushed by ocean currents.
