A new satellite photo has revealed that the "megaberg," A23a, is beginning to break apart, spawning thousands of smaller ice chunks around the Antarctic island of South Georgia.

Iceberg A23a's origin goes back to 1986, when the Filchner Ice Shelf's leading edge broke off three icebergs. For decades, A23a was stuck to a sandbank in shallow waters.

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.

The iceberg, called A23a, was previously “trapped” spinning around an undersea mountain for several months, according to Andrew Meijers, a physical oceanographer at the British Antarctic Survey.

The iceberg, dubbed A23a, is caught in the churn of a powerful ocean current and revolving slowly, at a rate of around 15 degrees per day, according to the British Antarctic Survey, which shared ...

The world’s largest iceberg is on the move again, drifting through the Southern Ocean after months stuck spinning on the same spot, scientists from the British Antarctic Survey (BAS) have said.

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 ...
