Massive Antarctic Iceberg Finally Breaks Free After 30 Years

One of the world's largest icebergs, known as A23a, has started drifting beyond Antarctic waters after being grounded for over three decades. The iceberg, measuring around 4,000 square kilometers, had been stuck in the Weddell Sea since splitting from the Filchner Ice Shelf in 1986. Remote sensing experts from the British Antarctic Survey have observed its movement since 2020, and it is now picking up speed and moving towards sub-Antarctic South Georgia, aided by wind and ocean currents. The cause of its release is believed to be a natural progression rather than any specific environmental change.
