Fred Cirque
Fred Cirque () is a large cirque in the west side of Roots Heights, in the Sverdrup Mountains of Queen Maud Land, Antarctica. It was photographed from the air by the Third German Antarctic Expedition (1938–39). It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (NBSAE) (1949–52) and from air photos by the Norwegian expedition (1958–59). It was named for Ernest Frederick Roots Ernest Frederick "Fred" Roots (5 July 1923 – 18 October 2016) was a Canadian geologist, polar explorer, educator and public servant. After graduating with undergraduate and master's degrees in geology from the University of British Columbia and ..., chief geologist with the NBSAE.

Cirque
A (; from the Latin word ') is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic , meaning a pot or cauldron) and (; ). A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides. The floor of the cirque ends up bowl-shaped, as it is the complex convergence zone of combining ice flows from multiple directions and their accompanying rock burdens. Hence, it experiences somewhat greater erosion forces and is most often overdeepened below the level of the cirque's low-side outlet (stage) and its down-slope (backstage) valley. If the cirque is subject to seasonal melting, the floor of the cirque most often forms a tarn (small lake) behind a dam, which marks the down ...

Roots Heights
Roots Heights () is an ice-free heights between Reece Valley and Skarsdalen Valley in the Sverdrup Mountains, Queen Maud Land. Photographed from the air by the German Antarctic Expedition (1938–39).

Sverdrup Mountains
The Sverdrup Mountains ( no, Sverdrupfjella) are a group of mountains about long, standing just west of the Gjelsvik Mountains in Queen Maud Land, East Antarctica. With its summit at , Hamartind Peak forms the highest point in the Sverdrup Mountains. Discovery and naming First photographed from the air and roughly plotted by the Third German Antarctic Expedition (3rd GAE), 1938–1939. Mapped in detail by Norwegian cartographers from surveys and aerial photographs taken by the Norwegian–British–Swedish Antarctic Expedition (NBSAE), and again by a later Norwegian expedition. Named for Harald Sverdrup, Chairman of the Norwegian Committee for the NBSAE.

Queen Maud Land
Queen Maud Land ( no, Dronning Maud Land) is a roughly region of Antarctica claimed by Norway as a dependent territory. It borders the claimed British Antarctic Territory 20° west and the Australian Antarctic Territory 45° east. In addition, a small unclaimed area from 1939 was annexed in June 2015. Positioned in East Antarctica, it makes out about one-fifth of the continent, and is named after the Norwegian queen Maud of Wales (1869–1938). In 1930, the Norwegian Hjalmar Riiser-Larsen was the first person known to have set foot in the territory. On 14 January 1939, the territory was claimed by Norway. On 23 June 1961, Queen Maud Land became part of the Antarctic Treaty System, making it a demilitarised zone. It is one of two Antarctic claims made by Norway, the other being Peter I Island. They are administered by the Polar Affairs Department of the Norwegian Ministry of Justice and Public Security in Oslo. Most of the territory is covered by the east Antarctic ic ...

Third German Antarctic Expedition
New Swabia (Norwegian and german: Neuschwabenland) was a disputed Antarctic claim by Nazi Germany within the Norwegian territorial claim of Queen Maud Land and is now a cartographic name sometimes given to an area of Antarctica between 20°E and 10°W in Queen Maud Land. New Swabia was explored by Germany in early 1939 and named after that expedition's ship, , itself named after the German region of Swabia.McGonigal, David, Antarctica', frances lincoln ltd, 2009, , p. 367 Background Like many other countries, Germany sent expeditions to the Antarctic region in the late 19th and early 20th centuries, most of which were scientific. The late 19th century expeditions to the Southern Ocean, South Georgia, the Kerguelen Islands, and the Crozet Islands were astronomical, meteorological, and hydrological, mostly in close collaboration with scientific teams from other countries. As the 19th century ended, Germany began to focus on Antarctica. The first German expedition to Antarctica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History The Norwegian–British–Swedish Antarctic Expedition was the first expedition to Antarctica involving an international team of scientists. The expedition was led by John Schjelderup Giæver, a Norwegian author and polar researcher. The expedition had the goal of establishing whether climatic fluctuations observed in the Arctic were also occurring in the Antarctic.

Ernest Frederick Roots
Ernest Frederick "Fred" Roots (5 July 1923 – 18 October 2016) was a Canadian geologist, polar explorer, educator and public servant. After graduating with undergraduate and master's degrees in geology from the University of British Columbia and a doctorate from Princeton University, Roots joined the Scott Polar Research Institute and was appointed Chief Geologist for the 1949 to 1952 Norwegian–British–Swedish Antarctic Expedition. During the expedition, in addition to ground-breaking geological and glaciological research studies, he made a 189-day, unsupported dog sled journey across the continent; a record that still stood at the time of his death over six decades later. On his return to Canada he joined the Geological Survey of Canada with whom he served as a field geologist until 1958, when he left to help found the Polar Continental Shelf Program. After 14 years with PCSP, Roots left to act as science advisor to the newly created federal Department of the Environment, wh ...
