A giant iceberg broke this Friday on the Brunt ice shelf in Antarctica, near a research station in the Antarctic. British Antartic Survey (LOW).

The ice block, covering 1,270 square kilometers, will be even bigger than the North American city of New York, revealed the British Antartic Survey (BAS), in a statement.

Scientists detected, almost a decade ago, the increase in the number of cracks in the ice, with 150 meters of thickness.

However, a rift known as the North Rift began to expand against another, in November, growing one kilometer a day in January.

“Our teams at BAS have been preparing to break an iceberg on Brunt’s ice shelf for several years,” said the BAS director, Jane Francis, explaining that scientists receive daily updates on the ice shelf, through an automated network of high-precision GPS instruments and satellite imagery.

According to the CNN, the Halley research station, located on the Brunt ice shelf, is closed for the Antarctic winter and the team of 12 scientists had already left the site in early February.

“All the data is sent to Cambridge for analysis, so we know what’s going on even during the Antarctic winter, when there are no employees at the station, it’s pitch black and dark. temperature drops below -50ºC“, These Francis.

BAS moved the Halley Research Station further inland, in 2016, as a precaution and the team only works from there during the Antarctic summer, because evacuations would be difficult to carry out during the winter.

“Our job now is to keep an eye on the situation and assess any potential impact of the break in the remaining ice shelf,” said BAS’s Director of Operations, Simon Garrod.

“In the coming weeks or months, the iceberg may move away, run aground or remain close to Brunt’s ice shelf. Halley Station is located inside all the active chasms, in the part of the ice shelf that remains connected to the continent. Our network of GPS instruments will notify us in advance if the iceberg breaks cause changes in the ice around the station“Concluded Francis.
