The World's Largest Iceberg, A23a, is Spinning in Place

*Location*: The iceberg, A23a, is currently located just north of Antarctica, near the South Orkney Islands.

*Size*: A23a is the world's largest iceberg, with an area of approximately 1,500 square miles, making it more than twice the size of Greater London.

*Current Situation*: Instead of moving with the Antarctic Circumpolar Current (ACC), A23a is stuck in a Taylor Column, a rotating column of water, and is spinning in place.

*Reason for Stagnation*: The Taylor Column is caused by a 100km-wide bump on the ocean floor called Pirie Bank, which is obstructing the ocean current and creating a rotating swirl of water.

*Impact on Melting*: As long as A23a remains in the Taylor Column, its melting will be delayed ¹ ² ³ ⁴ ⁵.

- *Scientific Interest*: Scientists are fascinated by A23a's unusual behavior and are studying it to gain insights into ocean dynamics and iceberg behavior.
