A massive iceberg – larger than New York City – erupts in Antarctica

A massive iceberg - larger than New York City - erupts in Antarctica

a An enormous iceberg, bigger New York CityIt separated from the Antarctic ice shelf, according to researchers Friday.

The British Antarctic Survey (BAS) wrote in a study that the 490 square mile iceberg separated from the Brant Ice Shelf about a decade later after scientists began spotting cracks in the ice. statement. New York City has an area of ​​about 302 square miles.

“Our teams at BAS are groomed to give birth to a Brunt Ice Shelf iceberg,” said Professor Dam Jane Francis, Director of the British Antarctic Survey.

The first indication that the glacier will break occurred in November when a new gap – called the North Rift – headed towards another large gulf about 20 miles away. In January, the rift pushed northeast by more than half a mile every day, breaking through the 490-foot-thick floating ice shelf.

The glacier formed after the rift widened on the morning of February 26th, and was released from the rest [the] Floating ice shelf, ” according to BAS.

Francis said that BAS monitors the ice shelf daily using an automated network of high-precision GPS instruments surrounding the Halley Research Station, which measures how an ice shelf is deforming and moving. The teams also use satellite imagery from ESA, NASA, and the German TerraSAR-X satellite.

“Halley’s station is located in the interior of all active gaps, on a portion of the ice shelf that is still connected to the continent,” said Francis. “Our network of GPS devices will give us an early warning if the birth of this iceberg causes changes in the ice around our station.”

The team of 12 people left the Halle Research Station early last month, and it is now closed due to Antarctic winter. The station has been safe from disruption since it was moved indoors in 2016 to avoid two tracks – dubbed “Chasm 1” and “Halloween Crack”.

Francis added that in the coming weeks or months, the iceberg might move away or drift and stay near the Brant Ice Shelf.

“Our job now is to closely monitor the situation and assess any potential impact of the current calves on the remaining ice shelf,” said Simon Jarrod, Director of Operations at BAS. “We are constantly reviewing our contingency plans to ensure the safety of our staff, safeguard our research station, and keep delivering the science we do in Halle.”

The researchers said there was no evidence that climate change played a significant role in the event.

“The change in ice in Halle is a natural process and has nothing to do with childbirth events seen on Larsen C Ice Shelf,” according to BAS.
