Northwind Glacier
Northwind Glacier () is a large Antarctic glacier; one of the major sources of the Fry Glacier, in the Convoy Range, Victoria Land. The glacier drains the west part of Flight Deck Neve and flows north between Elkhorn Ridge and Sunker Nunataks to Fry Glacier. A lobe of the glacier flows west a short distance into the mouth of Greenville Valley. Named by the New Zealand Northern Survey Party (1956–57) of the Commonwealth Trans-Antarctic Expedition after the USCGC ''Northwind'' (WAGB-282), an icebreaker in the main American convoy into McMurdo Sound during Operation Deep Freeze 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.

Atka Glacier
Atka Glacier () is the glacier immediately east of Flagship Mountain, draining north into Fry Glacier in Victoria Land. It was discovered and named in 1957 by the New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition, 1956–58, and named after USS ''Atka'', an American icebreaker in the convoy to McMurdo Sound in the 1956–57 season.

Convoy Range
Convoy Range () is a broad mountain range in Antarctica. Much of the range has a nearly flat plateau-like summit, extending south from the Fry Saddle and ending at Mackay Glacier. The range has steep cliffs on its east side, but it slopes gently into the Cambridge Glacier on the western side. The New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition (1956–58) worked in this area in 1957. The party named the range for the main convoy into McMurdo Sound in the 1956–57 season, with the names of the various vessels being used for features in the range. Features Taff Y Bryn () is a ridgelike summit capped by dolerite (about 1,600 m), situated 1 nautical mile (1.9 km) west of Flagship Mountain in the Convoy Range. It is named after the River Taff in Wales, the toponym in Welsh literally means "Hill of the Taff." It was named by the 1976–77 Victoria University of Wellington Antarctic Expedition (VUWAE) led by Christopher J. Burgess. Othe ...

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commonwealth Trans-Antarctic Expedition
The Commonwealth Trans-Antarctic Expedition (CTAE) of 1955–1958 was a Commonwealth-sponsored expedition that successfully completed the first overland crossing of Antarctica, via the South Pole. It was the first expedition to reach the South Pole overland for 46 years, preceded only by Amundsen's expedition and Scott's expedition in 1911 and 1912. In keeping with the tradition of polar expeditions of the Heroic Age of Antarctic Exploration, the CTAE was a private venture, though it was supported by the governments of the United Kingdom, New Zealand, United States, Australia and South Africa, as well as many corporate and individual donations, under the patronage of Queen Elizabeth II. It was headed by British explorer Vivian Fuchs, with New Zealander Sir Edmund Hillary leading the New Zealand Ross Sea Support team. The New Zealand party included scientists participating in International Geophysical Year research while the British team were separately based at Halley Ba ...

USS Glacier (AGB-4)
USS ''Glacier'' (AGB-4) (later USCGC ''Glacier'' (WAG/WAGB-4)) was a U.S. Navy, then U.S. Coast Guard icebreaker which served in the first through fifteenth Operation Deep Freeze expeditions. ''Glacier'' was the first icebreaker to make her way through the frozen Bellingshausen Sea, and most of the topography in the area is named for her crew members. When built, ''Glacier'' had the largest capacity single armature DC motors ever installed on a ship. ''Glacier'' was capable of breaking ice up to thick, and of continuous breaking of thick ice at . Named for Glacier Bay, Alaska, USS ''Glacier'' was launched on 27 August 1954 at Ingalls Shipbuilding Corp., Pascagoula, Mississippi, sponsored by Mrs. Roscoe F. Good; and commissioned on 27 May 1955, CDR. E.H. Mayer USN, Commanding. ''Glacier'' is the only icebreaker built in the ''Glacier'' class, and was in U.S. Navy service for 11 years, and U.S. Coast Guard service for 21 years. Construction ''Glacier'' was essentially an impr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McMurdo Sound
McMurdo Sound is a sound in Antarctica. It is the southernmost navigable body of water in the world, and is about from the South Pole. Captain James Clark Ross discovered the sound in February 1841, and named it after Lt. Archibald McMurdo of HMS ''Terror''. The sound today serves as a resupply route for cargo ships and for airplanes that land on the floating ice airstrips near McMurdo Station. Physical characteristics Wildlife in the sound include killer whales, seals, Adélie penguins, and emperor penguins. Boundary and Extents The sound extends approximately 55 kilometers (34 mi) in length and width, and opens into the larger Ross Sea to the north. To the south, the sound is bounded by the Ross Ice Shelf cavity, to the west lies the Royal Society Range, and to the east is Ross Island. McMurdo Sound is separated from the McMurdo Ice Shelf (itself part of the Ross Ice Shelf) by the Haskell Strait. Winter Quarters Bay lies at the south end of the Sound, and is the s ...

Mountains Of Victoria Land
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
