It’s called A23a, and it first broke off the Filchner Ice Shelf way back in 1986! For decades, it was just chilling (literally) in the Weddell Sea, stuck on the seabed. Then it started moving ...

Slightly smaller than Rhode Island, A23a originally split from Antarctica’s Filchner Ice Shelf in 1986 and then remained grounded on the seabed in the Weddell Sea for over 30 years, according to ...

A larger ice formation broke off in 1986 from the Antarctic Filchner Ice Shelf when it cracked into three smaller pieces, A23a being one of them. Experts have tracked it and found that for months ...

In January 2025, researchers on the Schmidt Ocean Institute’s R/V Falkor (too) had to divert their plans after an iceberg roughly the size of Chicago broke away from the George VI Ice Shelf, a ...

A new study reveals there was a time when massive icebergs, like the ones we see in Antarctica today, were drifting less than 90 miles off the U.K. coastline. Scientists have for the first time ...

The iceberg originally broke off from the Filchner Ice Shelf in 1986 and had been stuck in the Weddell Sea for over 30 years. With a surface area of 3,360 square kilometers, the iceberg was ...

It can also cause further melting under ice shelves, leading to even faster ice loss. So it's crucial to understand how much subglacial water is generated and where it goes, as well as its effect ...
