Aurdalsegga Ridge
Aurdalsegga Ridge () is an irregular ridge long surmounted by Mount Nikolayev, rising immediately southeast of Aurdalen Valley in the Südliche Petermann Range of the Wohlthat Mountains in Antarctica. It was discovered and plotted from air photos by the Third German Antarctic Expedition, 1938–39, re-plotted from air photos and from surveys by the Sixth Norwegian Antarctic Expedition, 1956–60, and named "Aurdalsegga" ("the gravel valley A valley is an elongated low area often running between Hill, hills or Mountain, mountains, which will typically contain a river or stream running from one end to the other.

Südliche Petermann Range
Südliche Petermann Range (german: Südliche Petermannkette, also known as Söre Petermannkjeda, and Gory Otto Grotevolya) is one of the Petermann Ranges, trending NE-SW for from Svarthausane Crags to Gneiskopf Peak, in the Wohlthat Mountains, Queen Maud Land. Mount Neustruyev (also known as Gora Neustruyeva) is a 2,900 meter peak standing NNE of Gneiskopf Peak. Discovery and naming Südliche Petermann Range was discovered and plotted from air photos by the Third German Antarctic Expedition (1938-1939), led by Capt. Alfred Ritscher, which gave directional names to the eastern, middle and western units of the Petermann Ranges. This range was named Sore Petermannkjeda by Sixth Norwegian Antarctic Expedition, 1956–60, because of its southern position in association with other units in the Petermann Ranges. A German form of this name has been recommended by US-ACAN to agree with spellings adopted for the aforementioned ranges. Features * Aurdalsegga Ridge * Bystrov Rock * G ...

Wohlthat Mountains
Wohlthat Mountains (german: Wohlthatmassiv) is a large group of associated mountain features consisting of the Humboldt Mountains, Petermann Ranges, and the Gruber Mountains, located immediately east of the Orvin Mountains in Fimbulheimen in the central Queen Maud Land. Discovered by the Third German Antarctic Expedition (1938–1939), led by Capt. Alfred Ritscher, and named for Councilor of state Helmuth C.H. Wohlthat, who as economist and fiscal officer dealt with the organization of the expedition. The area was reconnoitered and aerially photographed by the 5th Indian Antarctic Expedition (Nov 1985-Mar 1986) with a three-month temporary summer camp established there. The area was revisited by later Indian Antarctic expeditions. Astor Rocks The Astor Rocks () are two small rock outcrops lying southeast of Mount Ramenskiy in the southeast extremity of the Wohlthat Mountains.

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] |
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] |
Sixth Norwegian Antarctic Expedition
The sixth Norwegian Antarctic Expedition (''Den norske antarktisekspedisjonen'') was a scientific expedition to Queen Maud Land in Antarctica. The expedition was based at Norway Station () which was located on the Fimbul Ice Shelf bordering the coast of Queen Maud Land. The expedition carried out survey work and scientific studies over a period of three-four years (1956–1960). The expedition was intended as part of Norway's participation in the International Geophysical Year, 1957-58. The crew set sail from Oslo on board two whaling ships, the ''Polarsirkel'' and ''Polarbjørn'', on 10 November 1956. The expedition was led by Sigurd Gunnarson Helle, a geodesist at Norsk Polarinstitutt. It included a total crew of fourteen researchers which was reduced to nine during the third year. Among their activities were topological mapping of the region. In 1960, King Olav V of Norway instituted the Antarctic Medal The Antarctic Medal is a civil decoration of Norway. Established by ...

Gravel
Gravel is a loose aggregation of rock fragments. Gravel occurs naturally throughout the world as a result of sedimentary and erosive geologic processes; it is also produced in large quantities commercially as crushed stone. Gravel is classified by particle size range and includes size classes from granule- to boulder-sized fragments. In the Udden-Wentworth scale gravel is categorized into granular gravel () and pebble gravel (). ISO 14688 grades gravels as fine, medium, and coarse, with ranges 2–6.3 mm to 20–63 mm. One cubic metre of gravel typically weighs about 1,800 kg (or a cubic yard weighs about 3,000 lb). Gravel is an important commercial product, with a number of applications. Almost half of all gravel production is used as aggregate for concrete. Much of the rest is used for road construction, either in the road base or as the road surface (with or without asphalt or other binders.) Naturally occurring porous gravel deposits have a ...

Valley
A valley is an elongated low area often running between Hill, hills or Mountain, 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 glacier, glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glaciation, 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 karst, areas of limestone bedrock, dry valleys may also result from drainage now taking place cave, underground rather than at the surface. Rift valleys arise principally from tectonics, earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms th ...

Ridges Of Queen Maud Land
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance. The sides of the ridge slope away from the narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size. Smaller ridges, especially those leaving a larger ridge, are often referred to as spurs. Types There are several main types of ridges: ;Dendritic ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly more erosion resistant rock, but not always – they often remain because there were more joints where the valleys formed or other chance occurrences. This type of ridge is generally somewhat random in orientation, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
