Sunker Nunataks
Sunker Nunataks () is a group of small, rounded nunataks rising through the ice on the east side of Northwind Glacier, similar in appearance to a reef at sea, in the 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 i ..., Victoria Land. So named by a 1989-90 New Zealand Antarctic Research Program (NZARP) field party. In Newfoundland fisherman's parlance, a sunker is a rocky reef. Nunataks of Victoria Land Scott Coast {{ScottCoast-geo-stub ...

Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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. ...

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 A meteorite is a solid piece of debris from an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
