Brunt Ice Shelf
The Brunt Ice Shelf borders the Antarctic coast of Coats Land between Dawson-Lambton Glacier and Stancomb-Wills Glacier Tongue. 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. The Brunt Icefalls () extend along Caird Coast for about , where 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

VXE-6
Antarctic Development Squadron Six (VXE-6 or ANTARCTIC DEVRON SIX, commonly referred to by its nickname, The Puckered Penguins) was a United States Navy air test and evaluation squadron based at Naval Air Station Point Mugu, California with forward operating bases at Christchurch, New Zealand and McMurdo Station, Antarctica. Established at Naval Air Station Patuxent River, Maryland on 17 January 1955 as Air Development Squadron Six (VX-6), the squadron's mission was to conduct operations in support of Operation Deep Freeze, the operational component of the United States Antarctic Program. The squadron relocated to Naval Air Station Quonset Point, Rhode Island on 1 February 1956. On 1 January 1969 the squadron was redesignated Antarctic Development Squadron Six (VXE-6). Following the closure of NAS Quonset Point in the 1970s, the squadron relocated to NAS Point Mugu. Using the tail codes ''XD'' (1955) and ''JD'' (1957), the squadron flew numerous aircraft over the course of its e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctic Field Camps
Many Antarctic research stations support satellite field camps which are, in general, seasonal camps. The type of field camp can vary – some are permanent structures used during the annual Antarctic summer, whereas others are little more than tents used to support short term activities. Field camps are used for many things, from logistics (Sky Blu) to dedicated scientific research (WAIS Divide Field Camp).

List Of Glaciers
A glacier ( ) or () is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. Because glacial mass is affected by long-term climate changes, e.g., precipitation, mean temperature, and cloud cover, glacial mass changes are considered among the most sensitive indicators of climate change. There are about 198,000 to 200,000 glaciers in the world. Glaciers by continent Africa Africa, specifically East Africa, has contained glacial regions, possibly as far back as the last glacier maximum 10 to 15 thousand years ago. Seasonal snow does exist on the highest peaks of East Africa as well as in the Drakensberg Range of South Africa, the Stormberg Mountains, and the Atlas Mountains in Morocco. Currently, ...

British Antarctic Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.

McDonald Ice Rumples
The McDonald Ice Rumples () constitute an ice rise in the Brunt Ice Shelf bordering the Weddell Sea in Antarctica, covering an area of . Ernest Shackleton's Imperial Trans-Antarctic Expedition reported a glacier in this vicinity in January 1915. It was named "Allan McDonald Glacier" after Allan McDonald of the British Association of Magallanes at Punta Arenas, who was chiefly responsible for raising funds for sending the schooner ''Emma'' on the third attempt, in July 1916, to rescue the 22 men of the ''Endurance'' left on Elephant Island. The Royal Society International Geophysical Year expeditions occupied Halley Research Station nearby (1955–59) and were familiar with this feature, and reported that in 1957 the maximum elevation above the general surface of the ice shelf, a few hundred metres from the ice front, was about . It has now been identified with "Allan McDonald Glacier", and for the sake of historical continuity the UK Antarctic Place-names Committee The UK Antar ...

Iceberg A-74
Iceberg A-74 is an iceberg that calved from the north side of the Antarctic Brunt Ice Shelf in February 2021. Its calving had been anticipated due to large ice rifts that opened up in September 2019 and spread in the Antarctic summer of 2020–21. The iceberg measured soon after calving. It has moved away from the Antarctic coast which allowed, on 13–14 March 2021, the research vessel ''Polarstern'' to complete a circumnavigation as part of a research expedition. The ''Polarstern'' has photographed the sea bed which has provided an insight into fauna that can survive up to from the nearest daylight. Calving The calving of the iceberg was much anticipated due to large rifts in the ice that appeared in September 2019, in the vicinity of the McDonald Ice Rumples. The rift spread very rapidly across part of the Brunt Ice Shelf in summer 2020–21. GPS equipment belonging to the British Antarctic Survey (BAS) first reported that the iceberg had calved on 26 February. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
