South African National Antarctic Programme
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 ...

Antarctic Treaty System
The Antarctic Treaty and related agreements, collectively known as the Antarctic Treaty System (ATS), regulate international relations with respect to Antarctica, Earth's only continent without a native human population. It was the first arms control agreement established during the Cold War, designating the continent as a scientific preserve, establishing freedom of scientific investigation, and banning Military activity in the Antarctic, military activity; for the purposes of the treaty system, Antarctica is defined as all the land and ice shelf, ice shelves south of 60th parallel south, 60°S latitude. Since September 2004, the Antarctic Treaty Secretariat, which implements the treaty system, is headquartered in Buenos Aires, Argentina. The main treaty was opened for signature on 1 December 1959, and officially coming into force, entered into force on 23 June 1961. The original signatories were the 12 countries active in Antarctica during the International Geophysical Year ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earth
Earth is the third planet from the Sun and the only astronomical object known to Planetary habitability, harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering Water distribution on Earth, 70.8% of Earth's crust. The remaining 29.2% of Earth's crust is land, most of which is located in the form of continental landmasses within Earth's land hemisphere. Most of Earth's land is at least somewhat humid and covered by vegetation, while large Ice sheet, sheets of ice at Polar regions of Earth, Earth's polar polar desert, deserts retain more water than Earth's groundwater, lakes, rivers, and Water vapor#In Earth's atmosphere, atmospheric water combined. Earth's crust consists of slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's outer core, Earth has a liquid outer core that generates a ...

Hydrogen Line
The hydrogen line, 21 centimeter line, or H I line is a spectral line that is created by a change in the energy state of solitary, electrically neutral hydrogen atoms. It is produced by a spin-flip transition, which means the direction of the electron's spin is reversed relative to the spin of the proton. This is a quantum state change between the two hyperfine levels of the hydrogen 1 s ground state. The electromagnetic radiation producing this line has a frequency of (1.42 GHz), which is equivalent to a wavelength of in a vacuum. According to the Planck–Einstein relation , the photon emitted by this transition has an energy of []. The constant of proportionality, , is known as the Planck constant. The hydrogen line frequency lies in the L band, which is located in the lower end of the microwave region of the electromagnetic spectrum. It is frequently observed in radio astronomy because those radio waves can penetrate the large clouds of interstellar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Department Of International Relations And Cooperation
The Department of International Relations and Cooperation (DIRCO) is the foreign ministry of the South African government. It is responsible for South Africa's relationships with foreign countries and international organizations, and runs South Africa's diplomatic missions. The department is headed by the Minister of International Relations and Cooperation, currently Ronald Lamola. Background Prior to 1927, the British government attended to the external affairs of South Africa, though the latter did have its own trade commissioners that were sent to various countries. In November 1926, at the Imperial Conference, the various prime ministers of the Dominions attended, with conference negotiating what became the Balfour Declaration and an autonomy for the domains within a Commonwealth of Nations. The South Africans could now communicate with the commonwealth countries and others directly without communicating through the countries governors-general. A Department of External Affai ...

Southern Ocean
The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the world ocean, generally taken to be south of 60th parallel south, 60° S latitude and encircling Antarctica. With a size of , it is the second-smallest of the five principal oceanic divisions, smaller than the Pacific Ocean, Pacific, Atlantic Ocean, Atlantic and Indian Ocean, Indian oceans, and larger than the Arctic Ocean. The maximum depth of the Southern Ocean, using the definition that it lies south of 60th parallel, was surveyed by the Five Deeps Expedition in early February 2019. The expedition's multibeam sonar team identified the deepest point at 60° 28' 46"S, 025° 32' 32"W, with a depth of . The expedition leader and chief submersible pilot Victor Vescovo, has proposed naming this deepest point the "Factorian Deep", based on the name of the crewed submersible ''DSV Limiting Factor'', in which he successfully visited the bottom for the first time on February 3, 2019 ...

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 onc ...
