Pitkevitch Glacier
Pitkevitch Glacier () is a glacier, 20 nautical miles (37 km) long, flowing north from the Admiralty Mountains along the west side of DuBridge Range. The glacier reaches the sea just east of Atkinson Cliffs, where it forms Anderson Icefalls. A portion of the terminus merges northwestward with Fendley Glacier.

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. Named by New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1957–58, after the former New Zealand cruiser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DuBridge Range
DuBridge Range () is a mountain range, over 20 nautical miles (37 km) long in the Admiralty Mountains. The range trends southwest–northeast between Pitkevitch Glacier and Shipley Glacier and terminates at the north coast of Victoria Land just west of Flat Island, Antarctica. This mountain range was first mapped by the United States Geological Survey from surveys and U.S Navy air photos, 1960–63, and was named by the Advisory Committee on Antarctic Names for Lee DuBridge, a member of the National Science Board for several years, and Science Advisor to the President of the United States, 1969–70. The mountain range lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare Cape Adare is a prominent cape of black basalt forming the northern tip of the Adare Peninsula and the north-easternmost extremity of Victoria Land, East Antarctica.

Atkinson Cliffs
Atkinson Cliffs () are high coastal cliffs, long, between the lower ends of Fendley Glacier and Pitkevitch Glacier on the north coast of Victoria Land, Antarctica. They were mapped in 1911 by the Northern Party of the British Antarctic Expedition, 1910–13, and named for Dr. Edward L. Atkinson, surgeon of the expedition. The cliffs lie on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare Cape Adare is a prominent cape of black basalt forming the northern tip of the Adare Peninsula and the north-easternmost extremity of Victoria Land, East Antarctica.

Fendley Glacier
Fendley Glacier () is a glacier, long, flowing northeast from the Admiralty Mountains to enter the sea between Mount Cherry-Garrard and the Atkinson Cliffs, on the north coast of Victoria Land, Antarctica. This geographical feature was first mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–63, and was named by the Advisory Committee on Antarctic Names for Tech.

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] |
Staff Sergeant
Staff sergeant is a rank of non-commissioned officer used in the armed forces of many countries. It is also a police rank in some police services. History of title In origin, certain senior sergeants were assigned to administrative, supervisory, or other specialist duties as part of the staff of a British Army regiment. As such they held seniority over sergeants who were members of a battalion or company, and were paid correspondingly increased wages. Their seniority was indicated by a crown worn above the three sergeant's stripes on their uniform rank markings. National variations Australia In the Australian Army and Cadets, the rank of staff sergeant is being phased out. It was usually held by the company quartermaster sergeant or the holders of other administrative roles. Staff sergeants are always addressed as "Staff Sergeant" or "Staff", never as "Sergeant" as it degrades their rank. "Chief" is another nickname though this is only used for the company chief clerk (in s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
