The map shows the different positions of the berg over the course of its three-year journey. In May 2021, the world’s largest iceberg - four times the size of Abu Dhabi - fell into the ocean in Antarctica after breaking off from the Ronne Ice Shelf. Antarctic icebergs are named from the Antarctic quadrant in which they were originally sighted, then a sequential number, and then if the iceberg breaks, a sequential letter is added. ![]() This is the second major calving in the area in the past two years. the tip of the shelf had been disintegrating into icebergs in a. The floating ice shelf flows at a rate of up to 2km per year west towards the sea and calves off icebergs regularly. East Antarctica’s Conger ice shelf a floating platform the size of Rome broke off the continent on March 15, 2022. Aerial video released on 26 February reveals a huge iceberg has separated from the Brunt Ice Shelf in Antarctica, almost 10 years after scientists first discovered cracks. Sensors on the surface of the Brunt Ice Shelf confirmed the split. The station sits on Antarctica’s up to 150m-thick Brunt Ice Shelf. A big iceberg roughly the size of Greater London has broken away from the Antarctic, close to Britain's Halley research station. Their work will continue until they are collected by aircraft on about February 6. Staff at the station maintain power supplies and facilities that keep the scientific experiments operating remotely through the winter. Since 2017, staff have been deployed to the station only during the Antarctic summer, from November to March. Giant iceberg breaks away from Antarctic ice shelf. In 2016, BAS relocated the Halley Research Station 23km inland of Chasm-1 after it began to widen. ![]() “All data are sent back to Cambridge for analysis, so we know what is happening even in the Antarctic winter - when there are no staff on the station, it is dark for 24 hours and the temperature falls below minus 50☌.” Research station relocated ![]() “These measure how the ice shelf is deforming and moving and are compared to satellite images from ESA, Nasa and the German satellite TerraSAR-X. “Measurements of the ice shelf are carried out multiple times a day using an automated network of high-precision GPS instruments that surround the station,” she said.
