Brunt Ice Shelf

It was named by the UK Antarctic Place-names Committee after David Brunt, British meteorologist, Physical Secretary of the Royal Society, 1948–57, who was responsible for the initiation of the Royal Society Expedition to this ice shelf in 1955.

It was the location of the base of the Royal Society Expedition, 1955–59 which was taken over as the British Halley Research Station.

[3] On 26 February 2021, the 1,270 km2 (490 sq mi) Iceberg A-74 duly broke away from the north-facing shelf, separating from the edge of the shelf at the McDonald Ice Rumples along the North Rift and finally joining the Brunt-Stancomb chasm.

[4][5] On 23 January 2023, the second major calving from this area occurred when the crack known as Chasm-1 fully extended through the ice shelf, creating a 1,550 km2 (600 sq mi) iceberg.

Chasm-1 had continued to grow since 2015 and by December 2022 extended across the entire ice shelf, marking the beginning of the calving event.
