LONDON – The world’s biggest iceberg is on the move after more than 30 years being stuck to the ocean floor.
A23a, as it’s called, calved from the Antarctic coastline in 1986, but almost immediately grounded in the Weddell Sea to become, essentially, an ice island.
At almost 4,000 sq km in area, it’s more than twice the size of Greater London.
The past year has seen it drifting at speed, and the berg is now about to spill beyond Antarctic waters.
A23a is a true colossus, and it’s not just its width that impresses. This slab of ice is some 400 meters thick. For comparison, the London Shard, the tallest skyscraper in Europe, is a mere 310 meters tall. (BBC)
