A, after years of drifting, now appears stuck near South Georgia Island. Once lodged in the Southern Weddell Sea for decades, it broke free and made a slow but steady journey north—only to potentially meet its demise in the shallows.

The iceberg spanned an area of 3,672 square kilometers (1,418 square miles) when measured in August 2024 – slightly smaller than Rhode Island and more than twice the size of London. It calved from the Filchner Ice Shelf in Antarctica in 1986 and then rested on the seabed in the Weddell Sea for more than 30 years.

The world's largest iceberg appears to have run aground off the coast of a remote British island home to millions of penguins and seals — potentially threatening local wildlife, but also providing an opportunity for research into such rare "megabergs.

A23a weighs nearly a trillion metric tons, making it the world’s largest active iceberg. It calved from Antarctica in 1986, making it the world’s oldest berg. And now, after drifting for half a decade, A23a has grounded itself about 56 miles (90 kilometers) south of South Georgia.

It is no strange sight to see icebergs break off of the Antarctic ice cap and drift away, like the gigantic sheet of ice that is currently heading for the island of South Georgia. But climate change is making it happen more frequently,

A massive superberg, four times as big as New York City, has halted east of the southern tip of South America.

The world’s largest and oldest iceberg, A23a, has come to a halt near South Georgia Island in the South Atlantic Ocean, according to the British Antarctic Survey.

The world's biggest iceberg appears to have run aground roughly 70 kilometres from a remote Antarctic island, potentially sparing the crucial wildlife haven from being hit, a research organisation sai
