Aviator Glacier
Aviator Glacier is a major valley glacier in Antarctica that is over long and wide, descending generally southward from the plateau of Victoria Land along the west side of Mountaineer Range, and entering Lady Newnes Bay between Cape Sibbald and Hayes Head where it forms the Aviator Glacier Tongue. A glacier is a mass of ice with sufficient thickness to flow away from the source area in lobes, tongues or masses. Glaciers are usually found at high latitudes or high elevations. The glacier was photographed from the air by Captain W.M. Hawkes, US Navy, on the historic first flight from New Zealand to McMurdo Sound on December 17, 1955. An attempt to reconnoiter it by helicopter and to land a party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE) on it had to be abandoned when USS ''Glacier'' was damaged in pressure ice in December 1958. It was named by NZGSAE, 1958–59, as a tribute to the hazardous work of pilots and other airmen in Antarctic exploratory and ...

Southern Cross Mountains
Southern Cross Mountains is the name applied to the group of Antarctic mountain ranges lying between the Mariner and Priestley Glaciers in Victoria Land. Seaward parts of this area were first viewed by Ross in 1841 and subsequently by expeditions led by Borchgrevink, Scott, Shackleton and Byrd. The precise mapping of its overall features was accomplished from U.S. Navy air photographs and surveys by New Zealand and American parties in the 1950s and 1960s. Named by the northern party of NZGSAE, 1965–66. Features Geographical features of Southern Cross Mountains include: Arrowhead Range Other features * Archambault Ridge * Aviator Glacier * Chisholm Hills * Cosmonette Glacier * Daughtery Peaks * Hades Terrace * Linn Mesa * Mount Jiracek * Schulte Hills * Shoemaker Glacier * Styx Glacier * Tinker Glacier The Tinker Glacier is a 40 kilometre (25 mile) long glacier in Antarctica, draining the central part of the Southern Cross Mountains and flowing SE into Wood Bay, ...

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. Archibald McMurdo of HMS ''Terror''. The sound today serves as a resupply route for cargo ships and for airplanes that land on the floating ice airstrips near McMurdo Station. Physical characteristics Wildlife in the sound include killer whales, seals, Adélie penguins, and emperor penguins. Boundary and Extents The sound extends approximately 55 kilometers (34 mi) in length and width, and opens into the larger Ross Sea to the north. To the south, the sound is bounded by the Ross Ice Shelf cavity, to the west lies the Royal Society Range, and to the east is Ross Island. McMurdo Sound is separated from the McMurdo Ice Shelf (itself part of the Ross Ice Shelf) by the Haskell Strait. Winter Quarters Bay lies at the south end of the Sound, and is the s ...

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). List by letters * List of glaciers in the Antarctic: A–H * List of glaciers in the Antarctic: I–Z See also * List of Antarctic and subantarctic islands * List of Antarctic ice rises * List of Antarctic ice shelves * List of Antarctic ice streams * List of glaciers * List of subantar ...

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] |
Ice Tongue
An ice tongue is a long and narrow sheet of ice projecting out from the coastline. An ice tongue forms when a valley glacier moves very rapidly (relative to surrounding ice) out into the ocean or a lake. They can gain mass from water freezing at their base, or by snow falling on top of them. Mass is then lost by calving or by melting. Ice tongues can range in length from to . Icebergs are often formed when ice tongues break off in part or wholly from the main glacier. Two examples of ice tongues are the Erebus Ice Tongue and the Drygalski Ice Tongue The Drygalski Ice Tongue, Drygalski Barrier, or Drygalski Glacier Tongue is a glacier in Antarctica, on the Scott Coast, in the northern McMurdo Sound of Ross Dependency, north of Ross Island.

Wood Bay
Wood Bay is a large bay which is bounded by Cape Johnson and Aviator Glacier Tongue on the north, and Cape Washington on the south, along the coast of Victoria Land, Antarctica. It was discovered in 1841 by Captain James Clark Ross Sir James Clark Ross (15 April 1800 – 3 April 1862) was a British Royal Navy officer and polar explorer known for his explorations of the Arctic, participating in two expeditions led by his uncle John Ross, and four led by William Edwa ..., Royal Navy, and named by him for Lieutenant James F.L.

Ross Sea
The Ross Sea is a deep bay of the Southern Ocean in Antarctica, between Victoria Land and Marie Byrd Land and within the Ross Embayment, and is the southernmost sea on Earth. It derives its name from the British explorer James Clark Ross who visited this area in 1841. To the west of the sea lies Ross Island and Victoria Land, to the east Roosevelt Island and Edward VII Peninsula in Marie Byrd Land, while the southernmost part is covered by the Ross Ice Shelf, and is about from the South Pole. Its boundaries and area have been defined by the New Zealand National Institute of Water and Atmospheric Research as having an area of . The circulation of the Ross Sea is dominated by a wind-driven ocean gyre and the flow is strongly influenced by three submarine ridges that run from southwest to northeast. The circumpolar deep water current is a relatively warm, salty and nutrient-rich water mass that flows onto the continental shelf at certain locations. The Ross Sea is covered with ice ...
