The #A23a megaberg is in its spinning era 💃💞 These dance moves down #IcebergAlley are part of the iceberg’s long, melty journey into warmer waters. Don’t be deceived by your screen size ...

The largest and oldest iceberg in the world, named A23a, is on the move again after being stuck in a votex for months near the South Orkney Islands. It is now drifting in the Southern Ocean.

A23a, as it's known, broke away from the Antarctic coastline way back in 1986, but it's only recently begun a big migration. For more than 30 years, it was stuck rigidly in the bottom-muds of the ...

However, A23a may not hold its size title for long, because as of May 16, it is only around 12 square miles (31 square km) larger than the next-biggest iceberg, D15A, according to the U.S ...

The huge iceberg A23a measures almost 1,500 square miles, roughly twice the size of Greater London, and is as tall as the Shard in London. Dr Andrew Meijers, physical oceanographer at British ...

A23a has held the “largest current iceberg” title several times since the 1980s, occasionally being surpassed by larger but shorter-lived icebergs, including A68 in 2017 and A76 in 2021.

A23a made worldwide news last week after it moved out of the Weddell Sea sector into the Southern Ocean. It calved from the Filchner Ice Shelf in 1986, before being grounded on the seabed nearby ...

A23a will likely be ejected into what's called the Antarctic Circumpolar Current, which will put it on a path that has become known as "iceberg alley," the BBC reports.

A23a, the world's biggest iceberg, is on the move 37 years after it broke off from Antarctica. The iceberg, which covers about 1,500 square miles, is set to enter the Atlantic Ocean.

A23a will have its legacy. Like all big bergs, its progressive melt will be dispersing the mineral dust that was caught up in its ice when still part of a glacier.

Known as A23a, the iceberg split from the Antarctic coastline in 1986 and soon became grounded in the Weddell Sea, "becoming, essentially, an ice island", said the BBC.
