The biggest iceberg in the world, named A23a, appears to have run aground after drifting around the Southern Ocean near Antarctica since 2020.

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 world’s largest iceberg has run aground off the coast of a remote island in the Atlantic Ocean, according to British researchers.

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 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.

The world's largest iceberg has run aground in shallow waters off the remote British island of South Georgia, home to millions of penguins and seals. The iceberg, which is about twice the size of Greater London, appears to be stuck and should start breaking up on the island's south-west shores.
