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.

Palmer Land
Palmer Land () is the portion of the Antarctic Peninsula, Antarctica that lies south of a line joining Cape Jeremy and Cape Agassiz. This application of Palmer Land is consistent with the 1964 agreement between the Advisory Committee on Antarctic Names and the UK Antarctic Place-Names Committee, in which the name Antarctic Peninsula was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69° S. Boundaries In its southern extreme, the Antarctic Peninsula stretches west, with Palmer Land eventually bordering Ellsworth Land along the 80° W line of longitude. Palmer Land is bounded in the south by the ice-covered Carlson Inlet, an arm of the Filchner-Ronne Ice Shelf, which crosses the 80° W line. This is the base of Cetus Hill. This feature is named after Nathaniel Palmer, an American sealer who explored the Antarctic Peninsula area southward of Deceptio ...

Scaife Mountains
The Scaife Mountains () is a group of mountains rising west of Prehn Peninsula and between the Ketchum and Ueda glaciers, in Palmer Land, at the base of Antarctic Peninsula. Discovered by the Ronne Antarctic Research Expedition (RARE) under Finn Ronne, 1947–48, who named these mountains for Alan M. Scaife of Pittsburgh, Pennsylvania, a contributor to the expedition. List of mountains * Mount Brundage () is a mountain located 12 nautical miles (22 km) west-southwest of Mount Terwileger in the south part of the Scaife Mountains. Discovered by RARE who named it for Burr Brundage, United States Department of State, who assisted in making arrangements for the expedition. *Mount Macnowski () is a mountain in the northern part of the Scaife Mountains, about west-southwest of Schmitt Mesa, near the base of the Antarctic Peninsula.

Gardner Inlet
Gardner Inlet () is a large, ice-filled inlet at the southwest side of Bowman Peninsula, on the east coast of Palmer Land, Antarctica. It was discovered by the Ronne Antarctic Research Expedition, 1947–48, under Finn Ronne, who named it for Irvine Clifton Gardner, a physicist at the National Bureau of Standards The National Institute of Standards and Technology (NIST) is an agency of the United States Department of Commerce whose mission is to promote American innovation and industrial competitiveness.

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.

Becker, legal counsel who assisted in the formation of RARE * Mount Brundage - Named ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finn Ronne
Finn Ronne (December 20, 1899 – January 12, 1980) was a Norwegian-born U.S. citizen and Antarctic explorer. Background Finn Ronne was born in Horten, in Vestfold county, Norway. His father, Martin Rønne (1861–1932), was a polar explorer who served in Roald Amundsen's successful expedition to the South Pole. Ronne received his education in engineering at Horten Technical College. In 1923 Finn Ronne immigrated to the U.S. and gained citizenship in 1929. After working at Westinghouse Electric Corporation for some years, he took part in two of Richard E. Byrd's expeditions to the South Pole, and in 1939 Ronne served as Byrd's executive officer helping discover one thousand miles of new coastline. After serving several years in the United States Navy, gaining the rank of captain, Ronne returned to Antarctica in the 1940s, with support of the American Geographical Society as the leader of the Ronne Antarctic Research Expedition. From 1946 to 1948 his team mapped and explored t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerald Ketchum
Rear Admiral Gerald L. Ketchum (5 December 1908 – 22 August 1992) was a career officer in the United States Navy. He served during World War II and the Korean War. He was a recipient of the Silver Star and also participated in four expeditions to Antarctica. Navy career Gerald Lyle Ketchum was born in Bellingham, Washington on 5 December 1908 and graduated from the United States Naval Academy in 1931. World War II During World War II Ketchum was a lieutenant commander and was placed in command of the destroyer USS ''Perkins'' (DD-377) on 1 March 1943. The ''Perkins'' was employed in operations in the waters off New Guinea. On 22 September 1943, during an operation in which his ship was assigned to screen a convoy of landing craft, Ketchum and the ''Perkins'' engaged ten attacking Japanese torpedo planes. Ketchum positioned the ''Perkins'' between the planes and the convoy, and despite being heavily strafed, simultaneously avoided two torpedoes by skillful maneuvering, shot ...

Marguerite Bay
Marguerite Bay or Margaret Bay is an extensive bay on the west side of the Antarctic Peninsula, which is bounded on the north by Adelaide Island and on the south by Wordie Ice Shelf, George VI Sound and Alexander Island. The mainland coast on the Antarctic Peninsula is Fallières Coast. Islands within the bay include Pourquoi Pas Island, Horseshoe Island, Terminal Island, and Lagotellerie Island. Marguerite Bay was discovered in 1909 by the French Antarctic Expedition under Jean-Baptiste Charcot, who named the bay for his wife. Named features Toadstool Rocks are a group of insular, ice-covered rocks that rise to about 250 cm above sea level in the southwest part of Marguerite Bay, east-southeast of Terminal Island. The rocks were roughly charted from RRS association with Mushroom Island and Puffball Islands. Endurance Reef is a reef in Marguerite Bay, lying west of Red Rock Ridge. The name is after HMS ''Endurance'' which at this position in February 1972 struck a ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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).
