"Trillion-tonne Iceberg A23a Completes Perfect Spin in Antarctica"

The world's largest iceberg, A23a, has completed a pirouette as it moves towards the Southern Ocean, spinning more than 360 degrees just north of the Antarctic Peninsula. The iceberg, about the size of Greater London, is gradually eroding and melting due to warmer waters as it travels north at a rate of about 30 miles per day. A23a, which had been grounded for 30 years, is being swept along 'iceberg alley' and is currently the largest iceberg in the world, but it is expected to eventually fragment. If it reaches South Georgia, it could potentially disrupt wildlife feeding routines.
