All geoscientists (and others) can submit their photographs and videos to this repository and, since it is open access, these images can be used for free by scientists for their presentations or publications, by educators and the general public, and some images can even be used freely for commercial purposes. An iceberg larger than New York City has broken off an ice shelf in Antarctica, scientists say. Imaggeo is the EGU’s online open access geosciences image repository.

Contains modified Copernicus Sentinel data, processed by Niklas Jordan. An iceberg twice the size of New York City is about to break off of Antarctica. Both East & West ice shelves are melting rapidly Thwaites Glacier or Doomsday Glacier is in the. Satellite image from Sentinel-2 of Iceberg A-81. Antarctic warming is up to 5 times the global average. About 90 percent of the icebergs that break off from all of Antarctica travel counterclockwise around the continent, hugging the coast, into the Weddell Sea from there they drift north toward. Currently 21 staff are on station working to maintain the power supplies and facilities that keep the scientific experiments operating remotely through the winter. Their work will continue until they are collected by aircraft around 6 February. Since 2017, staff have been deployed to the station only during the Antarctic summer (between November to March). In 2016, BAS took the precaution of relocating Halley Research Station 23 km inland of Chasm-1 after it began to widen. The glaciological structure of the Brunt Ice Shelf is complex, and the impact of calving events is unpredictable. BAS glaciologists, who have been monitoring the behaviour of the ice shelf, say that the area of the ice shelf where the research station is located currently remains unaffected by the recent calving events. The Brunt Ice Shelf is the location of BAS Halley Research Station. The break off is the second major calving from this area in the last two years and has taken place a decade after scientists at British Antarctic Survey (BAS) first detected growth of vast cracks in the ice.

The iceberg calved when the crack known as Chasm-1 fully extended through the ice shelf. This occurred on Sunday 22 January between 19.00 and 20.00 UTC during a spring tide. It calved after cracks that have been developing naturally over the last few years extended across the entire ice shelf, causing the new iceberg to break free.
