The world's largest iceberg, A23a, is stuck again. For more than 30 years, the giant frozen block — equivalent to the size of Rhode Island — was grounded on the sea floor in Antarctic coastal ...

T he 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.

For more than 30 years, the world’s largest iceberg was stuck in the Antarctic. Five times the size of New York City’s land area and more than 1,000 feet deep, the mammoth piece of ice finally ...

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 ...

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.

World's largest iceberg on the move after dislodging from ocean floor 04:09. The world's largest and oldest iceberg, named A23a, has run aground in shallow waters off the coast of South Georgia, a ...

The world's largest iceberg, A23a, has grounded 73 kilometers off South Georgia Island, alleviating concerns about a potential collision that could have disrupted the local wildlife's food supply.

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.

Since 2020, however, the mega-iceberg has been “drifting with the currents of the Southern Ocean towards South Georgia,” they added. A23a “has been watched closely” by BAS since then.

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 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.
