Coats Land is a region in Antarctica which lies westward of Queen Maud Land and forms the eastern shore of the Weddell Sea , extending in a general northeast–southwest direction between 20°00′W and 36°00′W. The northeast part was discovered from the Scotia by William S. Bruce , leader of the Scottish National Antarctic Expedition , 1902-1904. He gave the name Coats Land for James Coats , Jr., and Major Andrew Coats, the two chief supporters of the expedition.

8-532: Halley Bay was a location on the fast ice on the north-western margin of the Brunt Ice Shelf in Coats Land , Antarctica . The series of British Halley Research Stations were constructed near here and named after the bay. The original ice bay was transitory and no longer exists although other bays in the same area keep reforming and breaking off as the shelf calves into icebergs. The location contains

16-519: A 177 ha site which has been designated an Important Bird Area (IBA) by BirdLife International because it supported a breeding colony of about 22,500 emperor penguins (estimated from 2009 satellite imagery) although as of 2019 the colony has dispersed due to repeated failure of the sea ice. In addition to the recent seasonal failures of ice the Brunt Ice shelf is approaching a large calving event which will reshape this section of coast and leave

24-553: The Brunt-Stancomb chasm. As of 28 February, A-74 was located at 75° 13' South, 25° 41' West and measures 30 nautical miles (56 km) on its longest axis and 18 nautical miles (33 km) on its widest axis. 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 km (600 sq mi) iceberg. Chasm-1 had continued to grow since 2015 and by December 2022 extended across

32-411: The entire ice shelf, marking the beginning of the calving event. 75°40′S 25°00′W  /  75.667°S 25.000°W  / -75.667; -25.000 This Coats Land location article is a stub .

40-620: The ice shelf (cracks which clearly go all the way through to the sea) started expanding, which was expected to cause large parts of the Brunt Ice Shelf to break off within the next few years. On 26 February 2021, the 1,270 km (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

56-654: The steep ice-covered coast descends to Brunt Ice Shelf. The icefalls were discovered on 5 November 1967, in the course of a United States Navy Squadron VXE-6 flight over the coast in LC-130 aircraft, and was plotted by the United States Geological Survey from air photos obtained at that time. It was named by the Advisory Committee on Antarctic Names in association with the Brunt Ice Shelf. In 2012, previously stable large chasms in

64-897: 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 . The Brunt Icefalls ( 75°55′S 25°0′W  /  75.917°S 25.000°W  / -75.917; -25.000 ) extend along Caird Coast for about 80 kilometres (50 mi), where
