Bowsprit Moraine
Bowsprit Moraine () is a medial moraine, long, off the northeast point of Elkhorn Ridge, where Towle Glacier and Northwind Glacier join Fry Glacier, in the Convoy Range, Victoria Land. It is one of a group of nautical names in Convoy Range: the mapped form of the moraine protrudes like a bowsprit out from the end of Elkhorn Ridge. It was named by a 1989–90 New Zealand Antarctic Research Programme The New Zealand Antarctic Research Programme (NZARP) was a research program that operated a permanent research facility in Antarctica from 1959 to 1996.

Medial Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Prove ...

Elkhorn Ridge
Elkhorn Ridge () is a rugged ridge, long, between Towle Glacier and Northwind Glacier in the Convoy Range of Victoria Land. It was mapped by the United States Geological Survey from ground surveys and Navy air photos, and was named by the Advisory Committee on Antarctic Names in 1964 for the USNS ''Elkhorn'', a tanker in the American convoy into 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.

Towle Glacier
Towle Glacier () is a glacier in the Convoy Range of Victoria Land, draining northeast between Eastwind and Elkhorn Ridges into the Fry Glacier. It was first mapped in 1957 by the New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition (1956–58) and named for the USNS Private John R. Towle, an American freighter which carried a large proportion of the New Zealand New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean.

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.

Fry Glacier
Fry Glacier () is a glacier draining the slopes at the northeast corner of the Convoy Range and flowing along the south end of the Kirkwood Range into Tripp Bay, Victoria Land, Antarctica. It was first charted by the British Antarctic Expedition, 1907–09 The ''Nimrod'' Expedition of 1907–1909, otherwise known as the British Antarctic Expedition, was the first of three successful expeditions to the Antarctic led by Ernest Shackleton and his second expedition to the Antarctic.

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] |
Bowsprit
The bowsprit of a sailing vessel is a spar extending forward from the vessel's prow. The bowsprit is typically held down by a bobstay that counteracts the forces from the forestays. The word ''bowsprit'' is thought to originate from the Middle Low German word ''bōchsprēt'' – ''bōch'' meaning "bow" and ''sprēt'' meaning "pole". It is sometimes used to hold up the figurehead.

New Zealand Antarctic Research Programme
The New Zealand Antarctic Research Programme (NZARP) was a research program that operated a permanent research facility in Antarctica from 1959 to 1996. It was created by the Geophysics Division of New Zealand's Department of Scientific and Industrial Research (DSIR), originally based in Wellington. The programme promoted research in geochemistry, zoology, geology, botany, meteorology, and limnology. History NZARP began as a proposal by the New Zealand government, in 1953, for a research base in Antarctica. Its mission was to provide support for a variety of scientific fieldwork in Antarctica. Members worked as researchers, assistants, tour guides, operators, and administrators to Scott Base. Ground was broken for Scott Base on 10 January 1957. Assembly of the base began 12 January, conducted by the eight men who first assembled the base in Wellington, and was completed by 20 January. In 1959, the NZARP was established to work with the Ross Dependency Research Committee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
