Dory Nunatak
Dory Nunatak () is an isolated sandstone nunatak, 1.2 nautical miles (2.2 km) long, rising above the southwest part of Flight Deck Neve, 1.5 nautical miles (3 km) southwest of Dotson Ridge, in the Convoy Range, Victoria Land. One of a group of nautical names in the Convoy Range, it was so named by a 1989–90 New Zealand Antarctic Research Programme party because the feature appears to be sailing in the midst of the glacier névé like a small dory A dory is a small, shallow-draft boat, about long.

Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Deck Neve
Flight or flying is the process by which an object moves through a space without contacting any planetary surface, either within an atmosphere (i.e. air flight or aviation) or through the vacuum of outer space (i.e. spaceflight). This can be achieved by generating aerodynamic lift associated with gliding or propulsive thrust, aerostatically using buoyancy, or by ballistic movement. Many things can fly, from animal aviators such as birds, bats and insects, to natural gliders/parachuters such as patagial animals, anemochorous seeds and ballistospores, to human inventions like aircraft (airplanes, helicopters, airships, balloons, etc.) and rockets which may propel spacecraft and spaceplanes. The engineering aspects of flight are the purview of aerospace engineering which is subdivided into aeronautics, the study of vehicles that travel through the atmosphere, and astronautics, the study of vehicles that travel through space, and ballistics, the study of the flight of project ...

Dotson Ridge
Dotson Ridge () is a ridgelike nunatak, 1.5 nautical miles (3 km) long, rising to in the northwest part of Flight Deck Neve, Convoy Range. It was mapped by the United States Geological Survey from ground surveys and Navy air photos, and was named by the Advisory Committee on Antarctic Names in 1964 for Morris F. Dotson, an electrician at McMurdo Station McMurdo Station is a United States Antarctic research station on the south tip of Ross Island, which is in the New Zealand-claimed Ross Dependency on the shore of McMurdo Sound in Antarctica.

Convoy Range
Convoy Range () is a broad mountain range in Antarctica. Much of the range has a nearly flat plateau-like summit, extending south from the Fry Saddle and ending at Mackay Glacier. The range has steep cliffs on its east side, but it slopes gently into the Cambridge Glacier on the western side. The New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition (1956–58) worked in this area in 1957. The party named the range for the main convoy into McMurdo Sound in the 1956–57 season, with the names of the various vessels being used for features in the range. Features Taff Y Bryn () is a ridgelike summit capped by dolerite (about 1,600 m), situated 1 nautical mile (1.9 km) west of Flagship Mountain in the Convoy Range. It is named after the River Taff in Wales, the toponym in Welsh literally means "Hill of the Taff." It was named by the 1976–77 Victoria University of Wellington Antarctic Expedition (VUWAE) led by Christopher J. Burgess. Othe ...

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Zealand Antarctic Research Programme
The New Zealand Antarctic Research Programme (NZARP) was a research program that operated a permanent research facility in Antarctica from 1959 to 1996. It was created by the Geophysics Division of New Zealand's Department of Scientific and Industrial Research (New Zealand), Department of Scientific and Industrial Research (DSIR), originally based in Wellington. The programme promoted research in geochemistry, zoology, geology, botany, meteorology, and limnology. History NZARP began as a proposal by the New Zealand government, in 1953, for a research base in Antarctica. Its mission was to provide support for a variety of scientific fieldwork in Antarctica. Members worked as researchers, assistants, tour guides, operators, and administrators to Scott Base. Ground was broken for Scott Base on 10 January 1957. Assembly of the base began 12 January, conducted by the eight men who first assembled the base in Wellington, and was completed by 20 January. In 1959, the NZARP was establishe ...

Névé
Névé is a young, granular type of snow which has been partially melted, refrozen and compacted, yet precedes the form of ice. This type of snow is associated with glacier formation through the process of ''nivation''. Névé that survives a full season of ablation turns into firn, which is both older and slightly denser. Firn eventually becomes glacial ice – the long-lived, compacted ice that glaciers are composed of. Glacier formation can take days to years depending on freeze-thaw factors. Névé is annually observed in skiing slopes, and is generally disliked as an icy falling zone. Névé has a minimum density of 500 kg/m3, which is roughly half of the density of liquid water at 1 atm. Névé can also refer to the alpine Alpine may refer to any mountainous region. It may also refer to: Places Europe * Alps, a European mountain range ** Alpine states, which overlap with the European range Australia * Alpine, New South Wales, a Northern Village * Alpine Nati ...

Dory
A dory is a small, shallow-draft boat, about long. It is usually a lightweight boat with high sides, a flat bottom and sharp bows. It is easy to build because of its simple lines. For centuries, the dory has been used as a traditional fishing boat, both in coastal waters and in the open sea. Definition Strictly speaking, the only true defining characteristic of the dory is that it is planked with wide straight boards running fore-and-aft; "It should be well understood, that it is the dory's special mode of construction, not its hull shape, that sets it, and its related sub-types apart from other boats".Gardner, page 15. More generally speaking, the dory can be defined as a small boat which has: * a flat bottom, with the bottom planks fastened lengthwise (bow to stern). * a hull shape defined by the natural curve of a sawn plank (never steam-bent). * planks overlapping the stem at the front of the boat and an outer "false" stem covering the hood ends of the planks. * (with som ...
