As of Jan. 16, the megaberg, known as A23a, is roughly 180 miles (290 kilometers) away from South Georgia and the South Sandwich Islands, according to location coordinates from the U.S. National Ice Center. A collision with these islands could be catastrophic for the large colonies of penguins, seals, and other wildlife that live there.

Measuring roughly 1,350 square miles (3,500 square kilometers) across, A23a is the world's largest and oldest iceberg according to AFP News. Its imposing size and slow, steady movement have captivated oceanographers and researchers alike, though predicting its exact path has proven difficult due to the unpredictable forces of ocean currents.

World's largest iceberg, A23a, is drifting towards the British island of South Georgia. A23a has been monitored for 30 years, since it first calved from Filchner ice shelf in Antarctica.

It’s also a natural process happening more frequently because of human-caused climate change, said British Antarctic Survey physical oceanographer Andrew Meijers, who examined the iceberg up close in December 2023 when it drifted past the research ship RRS Sir David Attenborough.

The colossal iceberg A23a, towering at 40 meters and spanning an area greater than the Australian Capital Territory, is now advancing towards South Georgia Island, a remote British territory near Antarctica.

The world’s largest iceberg is still on the move and there are fears that it could be headed north from Antarctica towards the island of South Georgia.

If it gets stuck near South Georgia Island, that could make it hard for penguin parents to feed their babies and some young could starve.

The world’s largest iceberg, A23a, is drifting northward from Antarctica, potentially threatening South Georgia, a British Overseas Territory in the South Atlantic. The massive iceberg, spanning 3,672 square kilometres (1,418 square miles), has raised fears of ecological disruption and risks to shipping routes.

The trillion-ton slab of ice that scientists call a "megaburg" broke off from the Antarctic’s Filchner Ice Shelf in 1986. Scientists catalogued it under the name A23a. It was stuck at sea for decades but confirmed to be moving again more than a year ago.
