Langevad Glacier
Borchgrevink Glacier () is a large glacier in the Victory Mountains, Victoria Land, Antarctica. It drains south between Malta Plateau and Daniell Peninsula, and thence projects into Glacier Strait, Ross Sea, as a floating glacier tongue. Exploration and naming It was named by the New Zealand Geological Survey Antarctic Expedition, 1957–58, for Carsten Borchgrevink, leader of the British Antarctic Expedition, 1898–1900. Borchgrevink visited the area in February 1900 and first observed the seaward portion of the glacier. Geography The Borchgrevink Glacier forms between Mount Frosch and Mount Lepanto in the Victory Mountains to the south of Trafalgar Glacier, and flows southeast and then south to the Ross Sea. It is joined by several small glaciers from the left (northeast) including Ingham Glacier just before O'Neal Ridge and Humphries Glacier just after that ridge. Humphries Glacier saddles with Whitehall Glacier, which flows northeast between the mainland and Daniell P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Zealand Antarctic Place-Names Committee
New Zealand Antarctic Place-Names Committee (NZ-APC) is an adjudicating committee established to authorize the naming of features in the Ross Dependency on the Antarctic continent. It is composed of the members of the New Zealand Geographic Board plus selected specialists on Antarctica. This committee works in collaboration with similar place-naming authorities in Australia, Great Britain and the United States to reach concurrence on each decision. The NZ-APC committee was established in 1956. Names attributed by the committee * Alberich Glacier, named after Alberich, king of the elves and chief of the Nibelungen * Arena Saddle, named in conjunction with Arena Valley * Brawhm Pass, named after the six party members of the University of New South Wales expeditions of 1964–65 and 1966–67 * Caliper Cove, named for descriptive features * Canada Stream, named in conjunction with Canada Glacier * Cape Crossfire, named for descriptive features * Cuneiform Cliffs, named for de ...

McMurdo Station
McMurdo Station is an American Antarctic research station on the southern tip of Ross Island. It is operated by the United States through the United States Antarctic Program (USAP), a branch of the National Science Foundation. The station is the largest community in Antarctica, capable of supporting up to 1,500 residents, though the population fluctuates seasonally; during the antarctic night, there are fewer than two hundred people. It serves as one of three year-round United States Antarctic science facilities. Personnel and cargo going to or coming from Amundsen–Scott South Pole Station usually first pass through McMurdo, either by flight or by the McMurdo to South Pole Traverse; it is a hub for activities and science projects in Antarctica. McMurdo, Amundsen-Scott, and Palmer are the three non-seasonal United States stations on the continent, though by the Antarctic Treaty System the bases are not a legal claim (though the right is not forfeited); they are dedicated to ...

Mount Alberts
The Malta Plateau () is an ice-covered plateau of about extent in the Victory Mountains of Victoria Land, Antarctica. The plateau is irregular in shape and is bounded on the south and west by Mariner Glacier, on the north by tributaries to Trafalgar Glacier, and on the east by tributaries to Borchgrevink Glacier. Name The Malta Plateau was named by the New Zealand Antarctic Place-Names Committee (NZ-APC) to commemorate the island of Malta in association with the Victory Mountains. Geology The plateau is part of the Melbourne Volcanic Province of the McMurdo Volcanic Group. Location The Malta Plateau is to the south of the Trafalgar Glacier, to the east and north of the Seafarer Glacier and the Mariner Glacier, and to the west of the Borchgrevink Glacier. The west of the plateau is drained by Potts Glacier to the south, Olson Glacier and Wilhelm Glacier to the west, Osuga Glacier and Trainer Glacier to the north. Features of the west include Mount Heg, Thomas Peak, Soft Snow P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clapp Ridge
Mount Riddolls () is a very prominent mountain, high, situated directly at the head of Rudolph Glacier in the Victory Mountains of Victoria Land, Antarctica. Name Mount Riddolls was named by the Mariner Glacier geology party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE) of 1966–67, for Bruce W. Riddolls, the assistant geologist with the party. Location Mount Riddolls is in the Victory Mountains above the head of the Borchgrevink Glacier. The Hand Glacier is to the south. It is east of the Malta Plateau and southwest of Mount Freeman The Clapp Ridge, Stever Ridge and Hackerman Ridge radiate from the mountain, as does the ridge that holds Mount Frosch. Mount Lopatin stands on the Stever Ridge. Features Clapp Ridge . A narrow, steep-sided ridge about long, forming the north wall of Hand Glacier.

Hallett Station
Cape Hallett is a snow-free area (Antarctic oasis) on the northern tip of the Hallett Peninsula on the Ross Sea coast of Victoria Land, East Antarctica. Cape Adare lies to the north. History In 1956, during Operation Deep Freeze II, was damaged by an ice floe at Cape Hallett. On 16 October 1958, a Douglas C-124C Globemaster II (52-1017) of the USAF crashed into a 3200-foot mountain near Cape Hallett Bay while maneuvering, killing 7 of the 13 occupants. The Globemaster was on an airdrop flight from Christchurch to McMurdo Station and other navigational errors had occurred prior to the crash. Hallett Station The cape was the location of a joint scientific base, Hallett Station, between the United States and New Zealand during the International Geophysical Year of 1957, and was manned permanently until 1964, when there was a major fire. It was then used as a summer only base until 1973. The site is currently being remediated by removing hazardous materials: fuel, and oi ...

Narrow Neck, Antarctica
Daniell Peninsula () is the large peninsula between Cape Daniell and Cape Jones on the coast of Victoria Land, Antarctica. It is an elongated basalt dome similar to Adare Peninsula and Hallett Peninsula and rises to . It is partly separated from the Victory Mountains by Whitehall Glacier, which is afloat in its lower reaches, but is joined to these mountains by the higher land in the vicinity of Mount Prior. It was named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1957–58, after Cape Daniell, and by analogy with the Adare and Hallett peninsulas. Geology The Daniell Peninsula consists of at least four overlapping shield volcanoes that form part of the Hallett Volcanic Province of the McMurdo Volcanic Group. Mount Brewster forms the central portion of the Daniell Peninsula and rises to an elevation of , forming the highest point on the peninsula.

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] |
