Rayner Glacier
Rayner Glacier () is a prominent glacier, wide, flowing north to the coast of Enderby Land just west of Condon Hills. It was sighted in October 1956 by Squadron Leader D. Leckie during a flight in an ANARE (Australian National Antarctic Research Expeditions) Beaver aircraft, and named by ANCA for J.M. Rayner, Director of the Bureau of Mineral Resources in the Australian Department of National Development.

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.

Enderby Land
Enderby Land is a projecting landmass of Antarctica. Its shore extends from Shinnan Glacier at about to William Scoresby Bay at , approximately of the earth's longitude. It was first documented in western and eastern literature in February 1831 by John Biscoe aboard the whaling brig ''Tula'', and named after the Enderby Brothers of London, the ship's owners who encouraged their captains to combine exploration with sealing. Nation state claims Subject to the constraints of the Antarctic Treaty System, the longest-held nation-state claimant rights in the territory is Australia, being a large part of its claimed Australian Antarctic Territory up to various high latitudes towards the South Pole. Features Coastal features include Amundsen Bay, Casey Bay and Cape Monakov. Mountain ranges or sub-ranges being crests above pack ice (escarpments), are the Scott Mountains, the Tula Mountains, and the Napier Mountains. The highest peak is Mount Elkins at Above Ordnance Datum (convent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Condon Hills
The Condon Hills () are a group of hills rising to along the east side of Rayner Glacier, Enderby Land. They were plotted from air photos taken by Australian National Antarctic Research Expeditions in 1956 and 1957, and named by the Antarctic Names Committee of Australia for M.A. Condon, Assistant Director, Bureau of Mineral Resources, Canberra, Australia.

Australian National Antarctic Research Expeditions
The Australian National Antarctic Research Expeditions (ANARE ) is the historical name for the Australian Antarctic Program (AAp) administered for Australia by the Australian Antarctic Division (AAD). History Australia has had a long involvement in south polar regions since as early as Douglas Mawson's Australasian Antarctic Expedition in 1911. Further Australian exploration of the Antarctic continent was conducted during the British Australian and New Zealand Antarctic Research Expedition (BANZARE), which was conducted over the years 1929–1931. The Australian National Antarctic Research Expeditions were established in 1947 with expeditions to Macquarie Island and Heard Island. In 1948 the Australian Antarctic Division (AAD) was established to administer the expedition program. ANARE Name The name ANARE fell out of official use in the early 2000s. However current and former Australian Antarctic expeditioners continue to use the term informally as a means of identifica ...

Antarctic Names Committee Of Australia
The Australian Antarctic Names and Medals Committee (AANMC) was established to advise the Government on names for features in the Australian Antarctic Territory and the subantarctic territory of Heard Island and the McDonald Islands. The committee also issues nominations Governor General for the award of the Australian Antarctic Medal. Committee members were appointed by the Minister or Parliamentary Secretary responsible for Antarctic matters. The committee was founded in 1952 as the Antarctic Names Committee of Australia, and changed to the current name in 1982 to reflect the multiple functions that the committee is responsible for. The committee was replaced by the Australian Antarctic Division Place names Committee in 2015. Features named by the committee * Fyfe Hills, named after W.V.

Bureau Of Mineral Resources
Geoscience Australia is an agency of the Australian Government. It carries out geoscientific research. The agency is the government's technical adviser on all aspects of geoscience, and custodian of the geographic and geological data and knowledge of the nation. On a user pays basis it produces geospatial products such as topographic maps and satellite imagery. It is also a major contributor to the Australian Government's free, open data collections such as data.gov.au. Strategic priorities The agency has six strategic priority areas: # building Australia's resource wealth in order to maximise benefits from Australia's minerals and energy resources, now and into the future; # ensuring Australia's community safety so that Australian communities are more resilient to natural hazards; # securing Australia's water resources in order to optimise and sustain the use of Australia's water resources; # managing Australia's marine jurisdictions in order to maximise benefits from the ...

Ice Stream
An ice stream is a region of fast-moving ice within an ice sheet. It is a type of glacier, a body of ice that moves under its own weight. They can move upwards of a year, and can be up to in width, and hundreds of kilometers in length. They tend to be about deep at the thickest, and constitute the majority of the ice that leaves the sheet. In Antarctica, the ice streams account for approximately 90% of the sheet's mass loss per year, and approximately 50% of the mass loss in Greenland. The shear forces cause deformation and recrystallization that drive the movement, this movement then causes topographic lows and valleys to form after all of the material in the ice sheet has been discharged. Sediment also plays an important role in flow velocity, the softer and more easily deformed the sediment present, the easier it is for flow velocity to be higher. Most ice streams contain a layer of water at the bottom, which lubricates flow and acts to increase speed. Mechanics Ice str ...

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).
