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.

Hughes Range (Antarctica)
The Hughes Range is a high massive north–south trending mountain range in Antarctica, surmounted by six prominent summits, of which Mount Kaplan (4,230 m) is the highest. The range is located east of Canyon Glacier in the Queen Maud Mountains and extends from the confluence of Brandau and Keltie glaciers in the south, to the Giovinco Ice Piedmont in the north. Discovered and photographed by Rear Admiral Byrd on the baselaying flight of November 18, 1929, and named by the Advisory Committee on Antarctic Names on the recommendation of Byrd for Charles Evans Hughes, U.S. secretary of state, U.S. chief justice, and adviser/counselor of Byrd.

Ross Ice Shelf
The Ross Ice Shelf is the largest ice shelf of Antarctica (, an area of roughly and about across: about the size of France). It is several hundred metres thick. The nearly vertical ice front to the open sea is more than long, and between high above the water surface. Ninety percent of the floating ice, however, is below the water surface. Most of Ross Ice Shelf is in the Ross Dependency claimed by New Zealand. It floats in, and covers, a large southern portion of the Ross Sea and the entire Roosevelt Island located in the east of the Ross Sea. The ice shelf is named after Sir James Clark Ross, who discovered it on 28 January 1841. It was originally called "The Barrier", with various adjectives including "Great Ice Barrier", as it prevented sailing further south. Ross mapped the ice front eastward to 160° W. In 1947, the U.S. Board on Geographic Names applied the name "Ross Shelf Ice" to this feature and published it in the original U.S. Antarctic Gazetteer. In Januar ...

Giovinco Ice Piedmont
Giovinco Ice Piedmont () is an ice piedmont, wide, between Canyon Glacier and Perez Glacier, gradually descending north to the Ross Ice Shelf, Antarctica. It was named by the Advisory Committee on Antarctic Names for Frank A. Giovinco, Master of the USNS ''Private John R. Towle'' during U.S. Navy Operation Deep Freeze 1965. Frank Giovinco's nephew is the fine art photographer and artist Steve Giovinco Steve Giovinco is an American photographer. He created a hand-held large-format (8x8") camera in 1992. Life and career In the 1980s, Giovinco attended Yale University. In 1991 he had his first one-man exhibition, at the Kansas City Art Institu ..., whose work is loosely related to environmental changes.

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] |
Ensign Richard Perez
An ensign is the national flag flown on a vessel to indicate nationality. The ensign is the largest flag, generally flown at the stern (rear) of the ship while in port. The naval ensign (also known as war ensign), used on warships, may be different from the civil ensign (merchant ships) or the yacht ensign (recreational boats). Large versions of naval ensigns called battle ensigns are used when a warship goes into battle. The ensign differs from the jack, which is flown from a jackstaff at the bow of a vessel. In its widest sense, an ensign is just a flag or other standard. The European military rank of ensign, once responsible for bearing a unit's standard (whether national or regimental), derives from it (in the cavalry, the equivalent rank was cornet, named after a type of flag). Ensigns, such as the ancient Roman ensigns in the Arch of Constantine, are not always flags. National ensigns In nautical use, the ensign is flown on a ship or boat to indicate its organizational me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VX-6
Air Development Squadron Six (VX-6 or AIRDEVRON SIX, commonly referred to by its nickname, "puckered penguins") was a United States Navy Air Development Squadron based at McMurdo Station, Antarctica. Established at Naval Air Station Patuxent River, Maryland on 17 January 1955, the squadron's mission was to conduct operations in support of Operation Deep Freeze, the operational component of the United States Antarctic Program. Using the tail code ''XD'', the squadron flew numerous fixed-wing aircraft and helicopters over the course of its existence—many of which were pioneering endeavors. For example, the first air link between Antarctica and New Zealand was established by men and aircraft of VX-6 in 1955. The following year, a ski-equipped R4D Dakota of VX-6 became the first aircraft to land at the South Pole. In 1961, the first emergency midwinter medical evacuation flight was conducted from Byrd Station to Christchurch. In 1963, an LC-130F Hercules of VX-6 made the longest ...

Antarctic Support Activity
The Antarctic ( or , American English also or ; commonly ) is a polar region around Earth's South Pole, opposite the Arctic region around the North Pole. The Antarctic comprises the continent of Antarctica, the Kerguelen Plateau and other island territories located on the Antarctic Plate or south of the Antarctic Convergence. The Antarctic region includes the ice shelves, waters, and all the island territories in the Southern Ocean situated south of the Antarctic Convergence, a zone approximately wide varying in latitude seasonally. The region covers some 20 percent of the Southern Hemisphere, of which 5.5 percent (14 million km2) is the surface area of the Antarctica continent itself. All of the land and ice shelves south of 60°S latitude are administered under the Antarctic Treaty System. Biogeographically, the Antarctic realm is one of eight biogeographic realms of Earth's land surface. Geography As defined by the Antarctic Treaty System, the Antarctic regi ...

Operation Deepfreeze
Operation Deep Freeze (OpDFrz or ODF) is codename for a series of United States missions to Antarctica, beginning with "Operation Deep Freeze I" in 1955–56, followed by "Operation Deep Freeze II", "Operation Deep Freeze III", and so on. (There was an initial operation before Admiral Richard Byrd proposed 'Deep Freeze'). Given the continuing and constant US presence in Antarctica since that date, "Operation Deep Freeze" has come to be used as a general term for US operations in that continent, and in particular for the regular missions to resupply US Antarctic bases, coordinated by the United States military. Task Force 199 was involved. Prior to International Geophysical Year The U.S. Navy already had a record of earlier exploration in Antarctica. As early as 1839, Captain Charles Wilkes led the first U.S. Naval expedition into Antarctic waters. In 1929, Admiral Richard E. Byrd established a naval base at Little America I, led an expedition to explore further inland, and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McMurdo Station
McMurdo Station is a United States Antarctic research station on the south tip of Ross Island, which is in the New Zealand-claimed Ross Dependency on the shore of McMurdo Sound in Antarctica. It is operated by the United States through the United States Antarctic Program (USAP), a branch of the National Science Foundation. The station is the largest community in Antarctica, capable of supporting up to 1,258 residents, and serves as one of three year-round United States Antarctic science facilities. All personnel and cargo going to or coming from Amundsen–Scott South Pole Station first pass through McMurdo. By road, McMurdo is 3 kilometres (1.9 mi) from New Zealand's smaller Scott Base. History The station takes its name from its geographic location on McMurdo Sound, named after Lieutenant Archibald McMurdo of . The ''Terror'', commanded by Irish explorer Francis Crozier, along with expedition flagship ''Erebus'' under command of James Clark Ross, first charted the area ...
