Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Admiralty Mountains
The Admiralty Mountains (alternatively Admiralty Range) is a large group of high mountains and individually named ranges and ridges in northeastern Victoria Land, Antarctica. This mountain group is bounded by the Ross Sea, the Southern Ocean, and by the Dennistoun, Ebbe, and Tucker glaciers. The mountain range is situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare. It was discovered in January 1841 by Captain James Ross, who named them for the Lords Commissioners of the Admiralty under whose orders he served. The Admiralty Mountains are divided into the Dunedin Range, Homerun Range, and Lyttelton Range. Mountains and peaks This range includes the following mountains and peaks: Mount Achilles Mount Achilles is a prominent pyramidal mountain rising from the divide between Fitch Glacier and Man-o-War Glacier.

Glacier Terminus
A glacier terminus, toe, or snout, is the end of a glacier at any given point in time. Although glaciers seem motionless to the observer, in reality glaciers are in endless motion and the glacier terminus is always either advancing or retreating. The location of the terminus is often directly related to glacier mass balance, which is based on the amount of snowfall which occurs in the accumulation zone of a glacier, as compared to the amount that is melted in the ablation zone. The position of a glacier terminus is also impacted by localized or regional temperature change over time. Tracking Tracking the change in location of a glacier terminus is a method of monitoring a glacier's movement. The end of the glacier terminus is measured from a fixed position in neighboring bedrock periodically over time. The difference in location of a glacier terminus as measured from this fixed position at different time intervals provides a record of the glacier's change. A similar way of trac ...

Wallis Glacier
Wallis Glacier () is a glacier nearly 20 nautical miles (37 km) long in the northwest part of the Admiralty Mountains, Victoria Land. The glacier flows north and then northwest, eventually coalescing with the lower portions of Dennistoun Glacier, Dennistoun and Nash Glacier, Nash glaciers just before all three reach the sea just east of Cape Scott. Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1960–63. Named by Advisory Committee on Antarctic Names (US-ACAN) for Staff Sergeant Nathaniel Wallis, who perished in the crash of a C-154 Globemaster aircraft in this vicinity in 1958.

Dennistoun Glacier
The Dennistoun Glacier is a glacier, long, draining the northern slopes of Mounts Black Prince, Royalist and Adam in the Admiralty Mountains of Victoria Land in Antarctica. It flows northwest between the Lyttelton Range and Dunedin Range, turning east on rounding the latter range to enter the sea south of Cape Scott. The coastal extremity of the glacier was charted in 1911–12 by the Northern Party, led by Victor Campbell, of the British Antarctic Expedition, 1910–13. The geographical feature lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare. The glacier is named after Jim Dennistoun, a New Zealand alpinist who was in charge of the mules on board the '' Terra Nova'' on her way to Antarctica. The entire extent of the glacier was mapped by the U.S. Geological Survey from surveys and U.S. Navy aerial photography, 1960–63.

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VX-6
Air Development Squadron Six (VX-6 or AIRDEVRON SIX, commonly referred to by its nickname, "puckered penguins") was a United States Navy Air Development Squadron based at McMurdo Station, Antarctica. Established at Naval Air Station Patuxent River, Maryland on 17 January 1955, the squadron's mission was to conduct operations in support of Operation Deep Freeze, the operational component of the United States Antarctic Program. Using the tail code ''XD'', the squadron flew numerous fixed-wing aircraft and helicopters over the course of its existence—many of which were pioneering endeavors. For example, the first air link between Antarctica and New Zealand was established by men and aircraft of VX-6 in 1955. The following year, a ski-equipped R4D Dakota of VX-6 became the first aircraft to land at the South Pole. In 1961, the first emergency midwinter medical evacuation flight was conducted from Byrd Station to Christchurch. In 1963, an LC-130F Hercules of VX-6 made the longest ...

List Of Glaciers In The Antarctic
There are many glaciers in the Antarctic. This set of lists does not include ice sheets, ice caps or ice fields, such as the Antarctic ice sheet, but includes glacial features that are defined by their flow, rather than general bodies of ice. The lists include outlet glaciers, valley glaciers, cirque glaciers, tidewater glaciers and ice streams. Ice streams are a type of glacier and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined as any latitude further south than 60° (the continental limit according to the Antarctic Treaty System).
