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 ATM or atm often refers to: * Atmosphere (unit) or atm, a unit of atmospheric pressure * Automated teller machine, a cash dispenser or cash machine ATM or atm may also refer to: Computing * ATM (computer), a ZX Spectrum clone developed in Mo ....

Flagship Mountain
Flagship Mountain () is a prominent, conical rock peak, high, surmounting the southern part of the large rock mass between Northwind Glacier and Atka Glacier in the Convoy Range of Victoria Land, Antarctica. It was named by the New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition (1956–58) after the USS ''Glacier'', flagship of the American convoy into McMurdo Sound McMurdo Sound is a sound in Antarctica. It is the southernmost navigable body of water in the world, and is about from the South Pole. Captain James Clark Ross discovered the sound in February 1841, and named it after Lt.

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. ...

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 A meteorite is a solid piece of debris from an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benson Glacier
Benson Glacier () is a glacier about long, draining the east part of Flight Deck Névé and continuing east between Fry Glacier and Mackay Glacier into the north part of Granite Harbour where it forms a floating tongue. Exploration and naming Benson Glacier was mapped in 1957 by the New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition (1956–1958), and indicated as a somewhat longer glacier including the present Midship Glacier. It was named by the party after Noel Benson, formerly professor of geology at the University of Otago, New Zealand, whose publications include a major contribution to the petrology of Victoria Land. Location The Benson Glacier forms in the northeast end of Alatna Valley in the Convoy Range and flows northeast to the south of Mount Razorback, Dotson Ridge, Flagship Mountain, Mount Davidson (Antarctica) and Mount Nesbelan, which surround Flight Deck Névé. To the south the Benson Glacier flows past Mount Morrison, Mount B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scuppers Icefalls
Scuppers Icefalls () is a prominent line of icefalls, 5 nautical miles (9 km) long and nearly 400 m high, between Mount Razorback and Mount Nespelen in Convoy Range, Victoria Land. The icefalls are the main outflow draining from Flight Deck Neve into Benson Glacier Benson Glacier () is a glacier about long, draining the east part of Flight Deck Névé and continuing east between Fry Glacier and Mackay Glacier into the north part of Granite Harbour where it forms a floating tongue. Exploration and naming .... One of a group of nautical names in Convoy Range, this descriptive name is derived from the drainage of the feature, suggestive of stormwater on a ship's deck draining through scuppers along the rail.

New Zealand Geographic Board
The New Zealand Geographic Board Ngā Pou Taunaha o Aotearoa (NZGB) was established by the New Zealand Geographic Board Act 1946, which has since been replaced by the New Zealand Geographic Board (Ngā Pou Taunaha o Aotearoa) Act 2008. Although an independent institution, it is responsible to the Minister for Land Information. The board has authority over geographical and hydrographic names within New Zealand and its territorial waters. This includes the naming of small urban settlements, localities, mountains, lakes, rivers, waterfalls, harbours and natural features and may include researching local Māori names. It has named many geographical features in the Ross Sea region of Antarctica. It has no authority to alter street names (a local body responsibility) or the name of any country. The NZGB secretariat is part of Toitū Te Whenua Land Information New Zealand (LINZ) and provides the board with administrative and research assistance and advice. The New Zealand Geographi ...

Snow Fields Of Victoria Land
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is cold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scott Coast
Scott Coast () is the portion of the coast of Victoria Land, Antarctica between Cape Washington and Minna Bluff. It was named by the New Zealand Antarctic Place-Names Committee in 1961 after Captain Robert Falcon Scott, Royal Navy, leader of the ''Discovery'' Expedition (1901–1904) and the British Antarctic Expedition (1910-1913), who died on the return journey from the South Pole. Much of the early exploration of this coastline was accomplished by Scott and his colleagues, and many of the names in the region were bestowed by him. See also * Blue Glacier * Dreschhoff Peak * Nostoc Flats * Robbins Hill * Stoner Peak * Thoreson Peak * Weidner Ridge * Mount Band Mount Band () is a mountain on the Scott Coast of Victoria Land.
