NASA has revealed that an Antarctic ice shelf observed for decades is about to break free from a large iceberg. This piece of ice has about twice the area of ​​New York City with a visible crack monitored by scientists with the help of aerial images. The human presence on the Brunt Ice Shelf, where the cracks are located, was first established in 1955, according to NASA.

NASA shared two images of the Brunt ice floe – the first captured by the Landsat 5 in January 1986, then the most recent by the Landsat 8 in January 2019. A large visible crack in the images has greatly increased during of the last three decades and covers almost all the ice, which, according to NASA, should soon be released.

Joining the vertical crack is another visible near the top of the image called Halloween Crack. The two men will eventually meet, which will be perhaps the largest iceberg to break free from the ice Brunt. According to NASA, however, in the vast iceberg pattern, ice will not be monumental, and will probably not be among the top 20 icebergs by size.

NASA has stated that a melting point south of McDonald's ice cream could well destabilize the remaining pack ice. Although these ruptures (known as calving events) are common on pack ice, NASA describes this as "unknown" to the region.

The Halley Research Station, operated by the British Antarctic Survey, is located on the Brunt Ice Shelf. The base was established in 1956, but in recent years – 2017 and 2018 to be precise – it was left unattended during the winter due to concerns about increasing ice cracking.
