World’s largest iceberg

World’s largest iceberg is near its end

In May 2021, when it separated from its parent ice shelf in Antarctica, it was the biggest iceberg ever recorded. The iceberg has now disintegrated into smaller fragments, the largest of which being Antarctic iceberg A-76A, which is currently floating in the Drake passage. As it floats forever in the water, the largest portion of the world’s largest iceberg is drawing nearer to its doom.

Researchers captured a natural-color image of the berg using the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. The long, tabular shape of the iceberg is seen in the picture, which makes it stand out from sea ice found farther south in the Southern Ocean.

Currently drifting approximately 2,000 kilometres from its parent ice shelf in the Drake Passage, the iceberg is snuggled between the South Orkney Islands and the Elephant Islands in the Southern Ocean. It is made up of floating glacier fragments.

Icebergs are the floating pieces of glaciers or ice shelves, not sea ice, in accordance with NASA, who defines sea ice as frozen seawater that floats on the ocean’s surface. The world’s largest iceberg detached from the Ronne Ice Shelf in May 2021 and split into three further pieces within a month.

The location of the iceberg is in a choppy waterway between Cape Horn in South America and the South Shetland Islands in Antarctica, which include Elephant Island in this picture. According to the U.S. National Ice Center (USNIC), A-76A measured 135 kilometres long and 26 kilometres wide in June 2021, giving it a total area that was roughly twice as large as London.

“It remains to be seen where A-76A will drift next. It is already more than 500 kilometers north of its position in July 2022, when the European Space Agency’s Sentinel-1 satellite showed the berg passing the Antarctic Peninsula. Sentinel-1 satellites carry synthetic aperture radar instruments, which can observe surfaces even in the darkness of austral winter,” Nasa’s Earth Observatory stated in a release.

Icebergs are typically driven east by the strong Antarctic Circumpolar Current that flows through the Drake Passage, according to experts. Then they quickly melt in the area’s warmer seas as they rush northward toward the equator.
