Paris: The world’s largest iceberg has collapsed from the Antarctic ice shelf and floats in the Weddell Sea. European Space Agency Said.
The ESA, called A-76, said on Wednesday that it was roughly in the shape of Manhattan, but was more than 70 times larger and was featured in satellite imagery and is “currently the largest Berg in the world.”
The iceberg is about 170 kilometers (105 miles) long, 25 kilometers wide and 4,320 square kilometers in area, slightly larger than Mallorca, Spain.
Berg, which broke the western side of the Ronne Ice Shelf, was originally discovered by the British Antarctic Survey and confirmed using images from the Copernicus satellite.
It is the largest location in the world from the A-23A iceberg (about 3,880 square kilometers), which is also located in the Weddell Sea.
Last November, the world’s largest iceberg at the time appeared to be on a collision course with a remote island in the South Atlantic, home to thousands of penguins and seals, which could impede its ability to collect food.
The iceberg, known as the A68a, was also separated from the Larsen Ice Shelf, which warmed faster than any other part of the Earth’s southernmost continent.
160 kilometers long and 48 kilometers wide, the A68a collapsed before it damaged the abundant wildlife that inhabits the British Overseas Territories of South Georgia.
The average surface temperature of the Earth has risen by 1 degree Celsius since the 19th century, enough to increase the intensity of droughts, heat waves and tropical cyclones.
However, the Antarctic air was more than twice as warm.
The major mass of Larsen Ice Shelf on the peninsula, which had been stable for more than 10,000 years, collapsed within a few days in 1995 and again in 2002. Then, in 2008 and 2009, the nearby Wilkins Ice Shelf collapsed.
In both cases, previous studies have shown that a process known as hydraulic fracturing is likely to be the main cause.
Hydraulic fracturing occurs when water heavier than ice is poured from cracks on the surface of ice shelves, caused by surface warming, and the crushing is severely zippered to destroy the iceberg.
Icebergs are traditionally named after the first detected Antarctic quadrant, followed by serial numbers.
When they fall apart, more letters are added to distinguish the fragments.
