The world's largest iceberg is spinning in an ocean vortex with no end in sight

For months, a giant iceberg has been stuck in one spot in the Southern Ocean due to a rare set of circumstances. The iceberg, known as A23a, is the world’s largest and has been closely monitored by scientists since it broke off from Antarctica’s ice shelf in 1986. It is currently trapped in a spinning vortex of water caused by ocean currents hitting an underwater mountain. Despite slowly melting, the iceberg is not expected to impact rising sea levels. This unique phenomenon highlights the impact of the climate crisis on Antarctic ice sheets.
