Frostlendet Valley
Frostlendet Valley is an ice-filled valley, about long, draining northeastward along the south side of Hogfonna Mountain, in the Borg Massif of Queen Maud Land, Antarctica. It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–52) and named Frostlendet (the frost ground).

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 ...

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 ...

Norwegian–British–Swedish Antarctic Expedition
The Norwegian–British–Swedish Antarctic Expedition (also known as NBSX or NBSAE) (1949–1952) was the first Antarctica expedition involving an international team of scientists. The team members came from Norway, Sweden and the British Commonwealth of Nations. 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. A base known as Maudheim was established on the Quar Ice Shelf along the coast of Queen Maud Land in February 1950. This expedition laid the groundwork for the following Australian expeditions to Antarctic from 1954 to the early 1960s. Transportation The expedition was transported aboard a 600-ton sealer named that was powered by a German U-boat dies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Antarctica
The history of Antarctica emerges from early Western theories of a vast continent, known as Terra Australis, believed to exist in the far south of the globe. The term ''Antarctic'', referring to the opposite of the Arctic Circle, was coined by Marinus of Tyre in the 2nd century AD. The rounding of the Cape of Good Hope and Cape Horn in the 15th and 16th centuries proved that ''Terra Australis Incognita'' ("Unknown Southern Land"), if it existed, was a continent in its own right. In 1773, James Cook and his crew crossed the Antarctic Circle for the first time; however, although they discovered nearby islands, they did not catch sight of Antarctica itself. It is believed he was as close as from the mainland. On 27 January 1820, a Russian Empire, Russian expedition led by Fabian Gottlieb von Bellingshausen and Mikhail Lazarev discovered an ice shelf at Princess Martha Coast that later became known as the Fimbul Ice Shelf. Bellingshausen and Lazarev became the first explorers to see ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Valleys Of Queen Maud Land
A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally. F ...
