Iceberg A23a - Drone footage of the largest iceberg on earth, eroding in the Southern Ocean.

The enormous tabular iceberg A23a is currently drifting north from Antarctica. Here is raw footage from our encounter in the Southern Ocean. This tabular iceberg is nearly 4000km2, is up to 400m thick and weighs just short of 1 trillion tonnes. It is 40 nautical miles long and twice the size of greater London. Simply massive! © 2024 Ian Strachan & Richard Sidey. All Rights Reserved. All footage can be provided in 4K. Contact via for licensing enquiries.
