Borga Base
Borga Base was a semipermanent Antarctic research station operated by South Africa named after Borg Massif where it was located. It was created to house 4-5 people year-round and was 350 kilometers (220 miles) south of the location of South Africa's primary Antarctic research station, SANAE IV. Its main building was a Parcoll hut, a long hut with a semicircular frame resembling half a cylinder. History Borga Base was created with the support of Belgian aircraft during the International Geophysical Year and was inaugurated in 1969. In the years of its operation, expedition teams would attempt the traverse from SANAE to Borga Base using specialized tractors, though they were not always successful. In 1969, mechanic Gordon Mackie was the first casualty of South African Antarctic research when he fell to his death on the traverse between the two bases. In 1970, mechanical and weather difficulties forced the team to abandon their attempt to reach Borga. In 1971, mechanical issues once ...

Research Stations In Antarctica
Multiple governments have set up permanent research stations in Antarctica and these bases are widely distributed. Unlike the drifting ice stations set up in the Arctic, the research stations of the Antarctic are constructed either on rock or on ice that is (for practical purposes) fixed in place. Many of the stations are demographics of Antarctica, staffed throughout the year. A total of 42 countries (as of October 2006), all signatories to the Antarctic Treaty System, Antarctic Treaty, operate seasonal (summer) and year-round research stations on the continent. The population of people performing and supporting scientific research on the continent and nearby islands varies from approximately 4,000 during the summer season to 1,000 during winter (June). In addition to these permanent stations, approximately Antarctic field camps, 30 field camps are established each summer to support specific projects.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borg Massif
Borg Massif is a mountain massif, about long and with summits above , situated along the northwest side of the Penck Trough in Queen Maud Land, East Antarctica. The tallest peak, at , is Hogsaetet Mountain. The parallel, ice-filled Raudberg Valley and Frostlendet Valley trend northeastward through the massif, dividing its summits into three rough groups: Discovery and naming The feature was photographed from the air by the Third German Antarctic Expedition (1938–1939), led by Captain Alfred Ritscher, but was not correctly shown on the maps by the expedition. It was mapped in detail by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–1952), led by John Schjelderup Giæver. It was remapped by air photos taken by the Sixth Norwegian Antarctic Expedition (1958–1959). They named it "Borgmassivet" (the castle massif) in association with Borg Mountain, its most prominent feature. Features *Located at the nor ...

South African National Antarctic Program
The South African National Antarctic Programme (or SANAP) is the South African government's programme for research in the Antarctic and Subantarctic. Three research stations fall under this programme: the Antarctica research station SANAE IV, and one station each on the subantarctic islands Gough Island and Marion Island. These stations are managed and administered by the Directorate: Antarctic and Islands of the Department of Environmental Affairs. Borga Base was also operated by SANAP from 1969 to 1976. The mission of the South African National Antarctic Programme is to increase understanding of the natural environment and life in the Antarctic and Southern Ocean through appropriate science and technology. South Africa is one of the original signatory states of the Antarctic Treaty. Experiments In April 2017, SANAP launched an experiment on Marion Island called Probing Radio Intensity at high-Z from Marion (PRIZM), searching for signatures of the hydrogen line in the early ...

SANAE IV
SANAE IV is a current South African Antarctic research base located in Vesleskarvet, Queen Maud Land. The base is part of the South African National Antarctic Program (SANAP) and is operated by the South African National Antarctic Expedition. The other two SANAP bases are located on the Gough and Marion islands. Location Located in the Queen Maud Land region of Eastern or Greater Antarctica, SANAE IV is on top of a distinctive flat-topped nunatak, Vesleskarvet, on the fringe of the Ahlmann Range of mountains. The base is approximately from the edge of the continent (also known as the grounding line or hinge zone) and from the edge of the ice shelf. Vesleskarvet is completely surrounded by the glacial ice sheet. Concept The first three SANAE research stations were located on the Fimbul Ice Shelf near the coast, and were subject to the gradual snow burial and eventual crushing that occurs with all stations constructed in this fashion. With a vision of creating a m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Geophysical Year
The International Geophysical Year (IGY; french: Année géophysique internationale) was an international scientific project that lasted from 1 July 1957 to 31 December 1958. It marked the end of a long period during the Cold War when scientific interchange between East and West had been seriously interrupted. Sixty-seven countries participated in IGY projects, although one notable exception was the mainland People's Republic of China, which was protesting against the participation of the Republic of China (Taiwan). East and West agreed to nominate the Belgian Marcel Nicolet as secretary general of the associated international organization. The IGY encompassed eleven Earth sciences: aurora and airglow, cosmic rays, geomagnetism, gravity, ionospheric physics, longitude and latitude determinations (precision mapping), meteorology, oceanography, seismology, and solar activity. The timing of the IGY was particularly suited for studying some of these phenomena, since it covered th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
