The world's largest iceberg, A23a, is drifting away from Antarctica after being grounded for over three decades. The iceberg, about the size of Oahu, is 40 miles wide and weighs 1 trillion tons. Recent satellite images and timelapse footage captured its movement, and scientists explain the significance of its drift due to steering wind and ocean currents.
After being grounded for decades, the world's largest iceberg is on the move. A23a is 40 miles wide and weighs 1 trillion tons. It calved from the Filchner Ice Shelf in 1986. @BAS_News captured video from the RRS Sir David Attenborough of A23a floating into open waters. https://t.co/PYTJuBQkbS
The world’s largest iceberg is on the move, drifting out of the Southern Ocean because of steering wind and ocean currents. The “megaberg” broke off from an ice shelf more than three decades ago and has been pretty stationary ever since — until now. https://t.co/o2Foq6PMs3
