Iceberg the Size of 3 Times New York Breaks Away, Moves Here News – 7 hours ago


Jakarta, CNBC Indonesia – Researchers on Friday (24/11/2023) revealed the facts about the largest iceberg in the world that melted and broke free. The iceberg’s fragments moved for the first time in more than three decades.

With an area of ​​almost 4,000 square km, the Antarctic iceberg, named A23a, is estimated to be three times the size of New York City.

Since breaking free from the Filchner-Ronne Ice Shelf in West Antarctica in 1986, the iceberg that once housed a Soviet research station has been largely stranded after its base became trapped at the bottom of the Weddell Sea. But not anymore. Recent satellite images reveal that the iceberg, which weighs nearly a trillion metric tons, is now moving rapidly past the northern tip of the Antarctic Peninsula, aided by strong winds and currents.


“It’s very rare to see an iceberg of this size moving,” British Antarctic Survey glaciologist Oliver Marsh was quoted as saying ReutersSunday (26/11/2023).

As it grows stronger, the giant iceberg will likely be launched into the Antarctic Circumpolar Current. This would lead it towards the Southern Ocean via a pathway known as “iceberg passage” where similar species can be found bobbing in the dark waters.

“Over time, these iceberg fragments may thin out a bit and gain a little extra buoyancy that allows them to lift off the sea floor and be pushed along by ocean currents,” Marsh said.

On the other hand, A23a is also one of the oldest icebergs in the world. There is a possibility that A23a could be grounded again on the island of South Georgia. This will cause problems for Antarctic wildlife.

Millions of seals, penguins and seabirds breed on the island and feed in the surrounding waters. Behemoth A23a can cut off this access.

In 2020, another giant iceberg, A68 has raised concerns that it will collide with South Georgia, destroying marine life on the seabed and cutting off access to food.

Such a disaster could ultimately be prevented when the iceberg breaks up into smaller chunks, which is also likely to happen to A23a.

“However, an iceberg of this size has the potential to remain in the Southern Ocean for quite a long time, even though the temperature is much warmer, and could move further north towards South Africa, which could disrupt shipping,” Marsh said.
