Massive iceberg the size of London breaks off from Antarctica

Massive iceberg the size of London breaks off from Antarctica

An monumental 1,550-square-kilometre iceberg broke off from Antarctica’s Brunt Ice Shelf on Sunday throughout a spring tide, the British Antarctic Survey polar analysis group introduced on Tuesday.

The huge ice formation is concerning the measurement of London and its surrounding suburbs. Unlike a number of related iceberg occasions lately, researchers stated they didn’t imagine local weather change was liable for the large iceberg.

“This calving event has been expected and is part of the natural behaviour of the Brunt Ice Shelf. It is not linked to climate change,” stated BAS glaciologist Dominic Hodgson.

The fissure within the ice sheet, which researchers named Chasm-1, was found years in the past. In the years since, the hole widened till the chunk of ice broke away.

The iceberg, which has but to be named by the US National Ice Center, is now anticipated to float off with the present alongside the Antarctic coast like earlier huge icebergs.

British glacier researchers will proceed to watch the iceberg.

Last yr, researchers linked the break-off of a roughly 1,200-square-kilometer iceberg to local weather change, for the reason that melting of the ocean ice has accelerated considerably because of greater temperatures.

The British Antarctic Survey operates a analysis station on the Brunt Ice Shelf in Antarctica. The analysis group moved the station about 20 kilometres additional inland in 2016 in order that it could not be endangered by huge iceberg break-offs similar to these just lately noticed from the station.

Researchers work from the station through the Antarctic summer time, which runs from November to March. During the rest of the yr, researchers within the British college city of Cambridge monitor the area utilizing satellite tv for pc pictures from house companies ESA and NASA in addition to the German satellite tv for pc TerraSAR-X.

The Brunt Ice Shelf is probably the most carefully monitored ice shelf on Earth, in line with the British Antarctic Survey.
