The European Space Agency said that the world’s largest huge iceberg had burst from an ice shelf in Antarctica and floated in the Weddell Sea.
ESA said on Wednesday that it is called A-76, which is roughly equivalent to Manhattan but 70 times larger than Manhattan. It was picked up on satellite images and is “the largest iceberg in the world at present.”
The iceberg is about 170 kilometers (105 miles) long, 25 kilometers wide, and has an area of 4,320 square kilometers, slightly larger than the Spanish island of Mallorca.
The iceberg broke off the west side of the Ron Ice Shelf. It was originally discovered by the British Antarctic Survey and confirmed using Copernicus satellite images.
It replaced the A-23A iceberg and became the largest iceberg in the world with an area of approximately 3,880 square kilometers. The iceberg is also in the Weddell Sea.
In November last year, the world’s largest iceberg appeared to be colliding with a remote South Atlantic island with thousands of penguins and seals threatening their ability to collect food.
The iceberg, A68a, has also fallen off the Larsen Ice Shelf, and the Larsen Ice Shelf is warming faster than anywhere else in the southernmost part of the earth.
A68a is 160 kilometers long and 48 kilometers wide, and it ruptured before it could cause any damage to the abundant wildlife in the British Overseas Territory of South Georgia.
Since the 19th century, the average surface temperature of the earth has risen by 1 degree Celsius, enough to increase the intensity of droughts, heat waves and tropical cyclones.
But the air over Antarctica has more than doubled.
The main part of the Larsen Ice Shelf on the peninsula (which has been stable for more than 10,000 years) collapsed in 1995 and within a few days, followed by the collapse of the nearby Wilkins Ice Shelf in 2008 and 2009.
Earlier studies have shown that in both cases, the process known as hydraulic fracturing may be the culprit.
When water (heavier than ice) pours down from cracks on the ice shelf surface caused by surface warming, hydraulic fracturing occurs, violently forcing the cracks open, causing the iceberg to burst.
Traditionally, icebergs are named after the Antarctic quadrant and were originally discovered in it.
If they are separated, more letters are added to distinguish the fragments.
