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.

Churchill Mountains
The Churchill Mountains are a mountain range group of the Transantarctic Mountains System, located in the Ross Dependency region of Antarctica. They border on the western side of the Ross Ice Shelf, between Byrd Glacier and Nimrod Glacier. Several of the range's highest summits, including Mounts Egerton, Field, Nares, Wharton, and Albert Markham were first seen and named by the Discovery Expedition of 1901–1904 (aka: British National Antarctic Expedition), under Robert Falcon Scott The mountains were mapped in detail by the USGS from Tellurometer surveys during 1960–61, and by United States Navy air photos in 1960. They were named by the US-ACAN for Sir Winston Churchill.

Mount Frost
Mount Frost () is a mountain, 2,350 m, in the Churchill Mountains of Antarctica, standing 4 nautical miles (7 km) south of Mount Zinkovich, at the south side of the head of Silk Glacier. Named by Advisory Committee on Antarctic Names (US-ACAN) for Lieutenant Colonel Foy B. Frost, United States Air Force (USAF), commanding officer of the Ninth Troop Carrier Squadron, which furnished C-124 Globemaster airlift support between New Zealand and the Antarctic and from McMurdo Sound inland to Byrd, Eights, and South Pole Stations South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west.

Mount Zinkovich
Mount Zinkovich () is a pointed mountain, high, standing north of Mount Frost at the north side of the head of Silk Glacier in the Churchill Mountains of Antarctica. Name Mount Zinkovich was named by US-ACAN for Lt. Col. Michael Zinkovich, USAF, commanding officer of the 1710th Aerial Port Squadron, which furnished airlift support between New Zealand and Antarctica, and from McMurdo Sound inland to Byrd, Eights, and South Pole Stations during USN OpDFrz 1962. Location Mount Zinkovich is on a ridge that extends from Pyramid Mountain to the south, through Mount Coley, Mount Frost, Mount Zinkovich and further north past Mount Wharton and Turk Peak. The Silk Glacier is fed from this ridge just south of Mount Zinkovich and flows east to join Nursery Glacier. The Jorda Glacier is fed from the ridge between Pyramid Mountain and Mount Coley, and also flows east to join Nursery Glacier. To the west is the Byrd Névé, from which rise the Wallabies Nunataks and the All-Blacks Nunataks. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nursery Glacier
Nursery Glacier () is a coastal glacier in the Churchill Mountains of Anarctica. Location The glacier is about 20 nautical miles (37 km) long. It flows southeast along the west side of Darley Hills to enter Ross Ice Shelf just south of Cape Parr. It is joined from the west by the Silk Glacier in its upper reaches and the Jorda Glacier near its mouth. It merges with the larger Starshot Glacier coming from the south as it enters the ice shelf. The New Zealand Geological Survey Antarctic Expedition (NZGSAE) (1959–60) named it Nursery Glacier because it was on this glacier that a litter of husky pups was born. Tributaries Jorda Glacier . A glacier, about long that drains the east slopes of the Churchill Mountains between Mount Coley and Pyramid Mountain and merges with the lower Nursery Glacier just before the latter enters the Ross Ice Shelf.

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] |
HMNZS Endeavour II
His or Her Majesty's New Zealand Ship (HMNZS) is the ship prefix used to identify warships and shore facilities commissioned into the Royal New Zealand Navy (RNZN). It derives from " His Majesty's Ship" (HMS) used in the United Kingdom. The British monarch is also equally and separately the New Zealand head of state. Should the monarch be female, the designation also changes to "Her" rather than "His" Majesty. On 1 October 1941, King George VI fixed his signature to the approval for the Royal New Zealand Navy and from that date all ships officially received the designation. See also *List of ships of the Royal New Zealand Navy Sortable list of commissioned vessels of the Royal New Zealand Navy from its formation on 1 October 1941 to the present.

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and locative information about more than two million physical and cultural features throughout the United States and its territories, Antarctica, and the associated states of the Marshall Islands, Federated States of Micronesia, and Palau. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a per ... [...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 ...
