The world's largest iceberg, the A23a, which broke off the shores of Antarctica in 1986 and started moving in the spring of 2023, reached the clear waters of the Southern Ocean in mid-November.
Blocked by the ocean floor since breaking away from the ice pack in 1986, A23a has begun to move and is in danger of washing up on the island of South Georgia, where it would disturb wildlife.
In mid-November, the world's largest A23a iceberg came to the open in the Southern Ocean and was in danger of destruction. This was reported by the Arctic and Antarctic Research Institute (AANI). Experts predict that the iceberg will enter the Scoche Sea in the coming month, where it will either soon cease to exist or will remain in the Weddell cycle system and drift for several more years. A23a was formed in 1986 as a result of the breakaway of…
