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.

Tucker Glacier
Tucker Glacier is a major valley glacier of Victoria Land, about 144 km (90 mi) long, flowing southeast between Admiralty Mountains and Victory Mountains to the Ross Sea. There is a snow saddle at the glacier's head, just west of Homerun Range, from which Ebbe Glacier flows northwestward. The Biscuit Step allows good access near its junction with Trafalgar Glacier. Explored by NZGSAE, 1957–58, and named by them after Tucker Inlet, the ice-filled coastal indentation at the mouth of this glacier named by Captain James Clark Ross in 1841.

Borchgrevink Coast
The Borchgrevink Coast is that portion of the coast of Victoria Land between Cape Adare and Cape Washington. The name was recommended by New Zealand Antarctic Place-Names Committee in 1961 after Carsten Borchgrevink, a member of Henrik Johan Bull's expedition to this area, 1894–95, and leader of the British Antarctic Expedition, 1898–1900, the first to winter on the continent, at Cape Adare. Landmarks *Agate Peak is a peak situated in the southeast area of the Intention Nunataks, at the southwest margin of Evans Neve within the Borchgrevink Coast. So named by the New Zealand Antarctic Place-Names Committee because agate and other semi-precious stones were found here by the Southern Party of New Zealand Geological Survey Antarctic Expedition, 1966–67.

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] |
Antarctica

Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

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] |

Warrant Officer (United States)
In the United States Armed Forces, the ranks of warrant officer (U.S. uniformed services pay grades, grades W‑1 to W‑5; see ''Ranks and insignia of NATO, NATO: WO1–WO5'') are rated as officers above all non-commissioned officers, Officer candidate, candidates, cadets, and Midshipman, midshipmen, but subordinate to the lowest officer grade of Second Lieutenant (United States), O‑1 (NATO: OF‑1). This application differs from the Commonwealth of Nations and other militaries, where warrant officers are the most senior of the Other ranks (UK), other ranks (NATO: OR‑8 and OR‑9), equivalent to the U.S. Armed Forces grades of E‑8 and E‑9. Warrant officers are highly skilled, single-track specialty officers. While the ranks are authorized by Congress, each branch of the Uniformed services of the United States, uniformed services selects, manages, and uses warrant officers in slightly different ways.

Mountains Of Victoria Land
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
