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 ...

"If this happens (the iceberg grounding) it could seriously impede access to feeding grounds for the wildlife -- seals and penguins mostly -- that breed on the island," Dr. Andrew Meijers, an ...

Andrew Meijers / AP "The island acts as an obstacle for ocean currents and therefore usually diverts the water long before it reaches the island," he said. "The iceberg is moved by ...

Dr. Andrew Meijers, an oceanographer at BAS, said experts do not expect the iceberg, which weighs nearly a trillion tons, to disrupt local wildlife if it remains aground, per BAS.

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 ...

“It kept sitting there until about 2020” says Andrew Meijers, science leader of the British Antarctic Survey’s polar oceans program. As it lingered, ...

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.

It’s also a natural process happening more frequently because of human-caused climate change, said British Antarctic Survey physical oceanographer Andrew Meijers, who examined the iceberg up ...

The trillion-ton slab of ice — called a megaberg — could slam into South Georgia Island, making it hard for penguin parents to feed their babies and some young could even starve.
