Coulter Glacier
Coulter Glacier () is a steeply inclined glacier, long, flowing south from the Havre Mountains, northern Alexander Island, into Kolokita Cove in Lazarev Bay, Antarctica. The glacier was photographed from the air by the Ronne Antarctic Research Expedition in 1947 and mapped from the photographs by the Falkland Islands Dependencies Survey in 1960. It was named by the Advisory Committee on Antarctic Names for R.W. Coulter, Master of USNS Alatna (T-AOG-81), USNS ''Alatna'' during U.S. Navy Operation Deepfreeze, 1969.

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.

Havre Mountains
The Havre Mountains () are a large group of mountains forming the northwestern extremity of Alexander Island, Antarctica, extending in an east–west direction between Cape Vostok and the Russian Gap. They were first seen in 1821 by a Russian expedition under Fabian Gottlieb von Bellingshausen and re-sighted by the Belgian Antarctic Expedition, 1897–99. They were roughly charted by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, who named them for Le Havre, the French port from which the ''Pourquoi-Pas (1908), Pourquol Pas?'' sailed in 1908. The mountains were mapped in detail from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960.

Alexander Island
Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west.Stewart, J. (2011) ''Antarctic An Encyclopedia'' McFarland & Company Inc, New York. 1776 pp. . Alexander Island is about long in a north–south direction, wide in the north, and wide in the south. Alexander Island is the second-largest uninhabited island in the world, after Devon Island. History Alexander Island was discovered on January 28, 1821, by a Russian expedition under Fabian Gottlieb von Bellingshausen, who named it Alexander I Land for the reigning Tsar Alexander I of Russia.

Lazarev Bay
Lazarev Bay is a rectangular bay, long and wide, which separates Alexander Island from Rothschild Island and is bounded on the south side by the Wilkins Ice Shelf, which joins the east portion of Rothschild Island and the west portion of Alexander Island (partially Cape Vostok, the Havre Mountains and the Lassus Mountains). Two minor islands, Dint Island and Umber Island, lie merged within the ice of the Wilkins Ice Shelf within Lazarev Bay. The north coast of Alexander Island was first seen from a great distance by the Russian expedition of 1821 under Fabian Gottlieb von Bellingshausen. The bay was first mapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960, and it was named by the UK Antarctic Place-Names Committee for Lieutenant Mikhail Petrovich Lazarev, second-in-command of Bellingshausen's expedition and commander of the sloop '' Mirnyy''.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . 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] |
Ronne Antarctic Research Expedition
The Ronne Antarctic Research Expedition (RARE) was an expedition from 1947–1948 which researched the area surrounding the head of the Weddell Sea in Antarctica. Background Finn Ronne led the RARE which was the final privately sponsored expedition from the United States and explored and mapped the last unknown coastline on earth and determined that the Weddell Sea and the Ross Sea were not connected. The expedition included Isaac Schlossbach, as second in command, who was to have Cape Schlossbach named after him. The expedition, based out of Stonington Island was the first to take women to over-winter. Ronne's wife, Edith Ronne was correspondent for the North American Newspaper Alliance for expedition and the chief pilot Darlington took his wife.

Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office. At the end of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
USNS Alatna (T-AOG-81)
USNS ''Alatna'', was a gasoline T1 tanker specially constructed for service in polar regions, was launched on 6 September 1956 at Staten Island, New York, by the Bethlehem Steel Corporation, sponsored by Mrs. Wilma Miles, and placed in service with the Military Sea Transportation Service in July 1957. Manned by a civil service crew, ''Alatna'' carried petroleum products from ports along the Atlantic and gulf coasts and in the Caribbean Sea to scattered American outposts in both polar regions. For more than 15 years, the tanker and her crew struggled against snow, wind, and ice to support American military bases in the Arctic and American scientists in the Antarctic. On 8 August 1972, ''Alatna'' was placed out of service and laid up with the Maritime Administration's National Defense Reserve Fleet at Suisun Bay, California. The Alatna Valley Alatna Valley (sometimes incorrectly spelled ''Atlanta Valley'') is an ice-free valley lying 4 miles (6 km) north of Mount Gran ...

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).
