Martin Sponholz is an American meteorologist. He was born in Burlington, Wisconsin. He moved to Milwaukee at the age of five (after the death of his parents) to live with relatives. Today he resides in New Ulm, Minnesota with his wife Nancy.
Sponholz has distinguished himself in the field of meteorological research serving on two expeditions to Antarctica. He was Chief Meteorologist on a team of eight at Plateau Station in Antarctica. He is credited with discovering "inversion winds", defined in Weather and Climate of the Antarctic, [1] and represented the U.S. on the Japanese Antarctic Research Expedition. [2] He authored Among the Magi , the story of his Antarctic journey during the 1960s. Martin received the Antarctica Service Medal for courage, devotion and sacrifice from President Lyndon B. Johnson in 1967. Sponholz Peak [3] in Antarctica is named in honor of Martin. Leaving the research world to teach, Martin began serving as professor of science at Martin Luther College in 1982 and continued teaching until the 2010-2011 school year, after which he retired.
The climate of Antarctica is the coldest on Earth. The continent is also extremely dry, averaging 166 mm (6.5 in) of precipitation per year. Snow rarely melts on most parts of the continent, and, after being compressed, becomes the glacier ice that makes up the ice sheet. Weather fronts rarely penetrate far into the continent, because of the katabatic winds. Most of Antarctica has an ice-cap climate with extremely cold and dry weather.
Davis Station, commonly called Davis, is one of three permanent bases and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Davis is situated on the coast of Cooperation Sea in Princess Elizabeth Land, Ingrid Christensen Coast in the Australian Antarctic Territory, a territory claimed by Australia. Davis lies in an Antarctic oasis, a mostly ice-free area known as the Vestfold Hills.
Mawson Station, commonly called Mawson, is one of three permanent bases and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Mawson lies in Holme Bay in Mac. Robertson Land, East Antarctica in the Australian Antarctic Territory, a territory claimed by Australia. Established in 1954, Mawson is Australia's oldest Antarctic station and the oldest continuously inhabited Antarctic station south of the Antarctic Circle. It houses approximately 20 personnel over winter and up to 53 in summer.
Vinson Massif is a large mountain massif in Antarctica that is 21 km (13 mi) long and 13 km (8 mi) wide and lies within the Sentinel Range of the Ellsworth Mountains. It overlooks the Ronne Ice Shelf near the base of the Antarctic Peninsula. The massif is located about 1,200 kilometres (750 mi) from the South Pole. Vinson Massif was discovered in January 1958 by U.S. Navy aircraft. In 1961, the Vinson Massif was named by the Advisory Committee on Antarctic Names (US-ACAN), after Carl G. Vinson, United States congressman from the state of Georgia, for his support for Antarctic exploration. On November 1, 2006, US-ACAN declared Mount Vinson and Vinson Massif to be separate entities. Vinson Massif lies within the unrecognised Chilean claim under the Antarctic Treaty System.
Scott Base is a New Zealand Antarctic research station at Pram Point on Ross Island near Mount Erebus in New Zealand's Ross Dependency territorial claim. It was named in honour of Captain Robert Falcon Scott, RN, leader of two British expeditions to the Ross Sea area of Antarctica. The base was set up as support to field research and the centre for research into earth sciences, and now conducts research in many fields, operated by Antarctica New Zealand.
Vostok Station is a Russian research station in inland Princess Elizabeth Land, Antarctica. Founded by the Soviet Union in 1957, the station lies at the southern Pole of Cold, with the lowest reliably measured natural temperature on Earth of −89.2 °C. Research includes ice core drilling and magnetometry. Vostok was named after Vostok, the lead ship of the First Russian Antarctic Expedition captained by Fabian von Bellingshausen. The Bellingshausen Station was named after this captain.
Dakshin Gangotri was the first scientific base station of India situated in Antarctica, part of the Indian Antarctic Programme. It is located at a distance of 2,500 kilometres (1,600 mi) from the South Pole. It is currently being used as a supply base and transit camp. The base is named after Dakshin Gangotri Glacier.
Palmer Station is a United States research station in Antarctica located on Anvers Island, the only US station located north of the Antarctic Circle. Initial construction of the station finished in 1968. The station, like the other U.S. Antarctic stations, is operated by the United States Antarctic Program (USAP) of the National Science Foundation. The base is about as distant from the equator as Fairbanks, Alaska.
The Antarctica Service Medal (ASM) was established by the United States Congress on July 7, 1960, under Public Law 600 of the 86th Congress. The medal was intended as a military award to replace several commemorative awards which had been issued for previous Antarctica expeditions from 1928 to 1941. With the creation of the Antarctica Service Medal, the following commemorative medals were declared obsolete;
Paul Allman Siple was an American Antarctic explorer and geographer who took part in six Antarctic expeditions, including the two Byrd expeditions of 1928–1930 and 1933–1935, representing the Boy Scouts of America as an Eagle Scout. In addition to being an Eagle Scout, Siple was also a Sea Scout. His first and third books covered these adventures. With Charles F. Passel he developed the wind chill factor, and Siple coined the term.
Operation Tabarin was the code name for a secret British expedition to the Antarctic during World War Two, operational 1943–46. Conducted by the Admiralty on behalf of the Colonial Office, its primary objective was to strengthen British claims to sovereignty of the British territory of the Falkland Islands Dependencies (FID), to which Argentina and Chile had made counter claims since the outbreak of war. This was done by establishing permanently occupied bases, carrying out administrative activities such as postal services and undertaking scientific research. The meteorological observations made aided Allied shipping in the South Atlantic Ocean.
McMurdo Sound, a sound in Antarctica, is the southernmost navigable body of water in the world, located approximately 1,300 kilometres (810 mi) from the South Pole.
Base Orcadas is an Argentine scientific station in Antarctica, and the oldest of the stations in Antarctica still in operation. It is located on Laurie Island, one of the South Orkney Islands, at 4 meters (13 ft) above sea level and 170 meters (558 ft) from the coastline. Established by the Scottish National Antarctic Expedition in 1903 and transferred to the Argentine government in 1904, the base has been permanently populated since, being one of six Argentine permanent bases in Argentina's claim to Antarctica, and the first permanently inhabited base in Antarctica.
Henryk Arctowski Polish Antarctic Station is a Polish research station on King George Island, off the coast of Antarctica.
Sir George Clarke Simpson KCB CBE FRS HFRSE was a British meteorologist. He was President of the Royal Meteorological Society 1940/41.
Henryk Arctowski, born Henryk Artzt, was a Polish scientist and explorer.
Plateau Station is an inactive American research and South Pole—Queen Maud Land Traverse support base on the central Antarctic Plateau. Construction on the site started on December 13, 1965, and the first traverse team arrived in early 1966. The base was in continuous use until January 29, 1969, when it was closed but mothballed for future use, and was the most remote and coldest of any United States stations on the continent. It was also the site for the world's coldest measured average temperature for a month at that time, recorded in July 1968, at −99.8 °F (−73.2 °C).
The Schirmacher Oasis is a 25 km (16 mi) long and up to 3 km (1.9 mi) wide ice-free plateau with more than 100 freshwater lakes. It is situated in the Schirmacher Hills on the Princess Astrid Coast in Queen Maud Land in East Antarctica and is, on average, 100 m (330 ft) above sea level. With an area of 34 km2 (13 sq mi), the Schirmacher Oasis ranks among the smallest Antarctic oases and is a typical polar desert.
Sponholz Peak is a sharp peak, 1,730 m, standing 2.5 nautical miles (4.6 km) south of Moulder Peak in Liberty Hills, Heritage Range, Antarctica. It was named by the Advisory Committee on Antarctic Names (US-ACAN) for Martin P. Sponholz, a United States Antarctic Research Program (USARP) meteorologist and a member of the winter party at Plateau Station in 1966. Sponholz is commemorated especially for his mathematical applications and formulas regarding inversion wind systems. Sponholz later served as a professor of physical sciences at Martin Luther College in New Ulm, Minnesota, USA.
