(TheProudRepublic.com) – After being stuck for over 30 years, the colossal ice mass twice the size of Greater London, A23a, has finally broken free and is now drifting towards the ocean.
This massive iceberg, spanning 3,672 to 3,800 square kilometers, originally calved from Antarctica’s Filchner-Ronne ice shelf in 1986.
It remained grounded in the Weddell Sea for decades, trapped by ocean currents and a unique rotating water phenomenon called a Taylor Column.
The British Antarctic Survey (BAS) recently announced that A23a is now drifting further north, heading towards the warmer waters of the South Atlantic Ocean.
This movement has sparked interest among scientists and researchers who are eager to study its impact on marine ecosystems.
While some may attempt to link this event to climate change, it is crucial to understand that iceberg calving is a natural part of the ice shelf cycle.
This process has been ongoing for thousands of years and does not contribute to the rise of sea levels.

The world's largest iceberg is on the move for the first time in more than three decades, scientists said on Friday.

“It’s exciting to see A23a on the move again after periods of being stuck,” Dr Andrew Meijers from the BAS said.
He expressed interest in whether A23a will follow the same route as other large icebergs that have calved off Antarctica.
Interestingly, researchers have noted that giant icebergs like A23a can benefit marine life by providing nutrients to less productive ocean areas.
Biogeochemist Laura Taylor, who collected samples from the water around the iceberg, said in the BAS statement, “We know that these giant icebergs can provide nutrients to the waters they pass through, creating thriving ecosystems in otherwise less productive areas.”
“What we don’t know is what difference particular icebergs, their scale, and their origins can make to that process,” she added.
As A23a continues its journey toward the Atlantic Ocean, it is expected to break up and melt in the warmer waters.
This natural process has been occurring for centuries, long before the invention of fossil fuels or the industrial revolution.
