World's Biggest Iceberg on Collision Course With Wildlife Haven Henry Ridgwell LONDON - The world's largest iceberg is on course to collide with the island of South Georgia, a key haven for wildlife in the south Atlantic Ocean, scientists say. They add it could have a grave impact on the ecology and economy of the island. The giant iceberg carved off the Larsen C ice shelf on the eastern Antarctic peninsula in 2017. Named by scientists as A68a, it has since drifted toward South Georgia, a remote British island. Satellite images show the iceberg is still largely intact. Some 150 kilometers long and 48 kilometers wide, it is traveling at one kilometer per hour and is on course to hit South Georgia in around 30 days. .
