The world's largest iceberg, A23a, is drifting towards the wildlife haven of South Georgia, where it may cause problems for the resident penguins

This is not the first time an iceberg has posed a threat to South Georgia. In 2004, iceberg A38 "grounded on its continental shelf, leaving dead penguin chicks and seal pups on beaches as massive ice chunks blocked their access to feeding grounds,

Incredible new satellite images show the world's largest iceberg on a potential collision course with South Georgia Island. On Jan. 22, NOAA’s GOES East satellite captured imagery of A23a slowly drifting northeastward in the Southern Ocean.

The world’s largest iceberg is on a collision course with a remote British island, potentially putting penguins and seals at risk. The iceberg, A23a, broke free from its position north of the South Orkney Islands last month and is now heading towards South Georgia, where it could crash into the island.

A giant iceberg, one of the largest ever recorded, is drifting dangerously close to the remote island of South Georgia, raising fears for its fragile ecosystem. The A23a iceberg, an ancient behemoth that broke free from Antarctica decades ago,
