Nødtvedt Nunataks
Nødtvedt Nunataks () is an isolated nunataks standing in mid-stream of the Amundsen Glacier, rising 7 nautical miles (13 km) east-northeast of Mount Bjaaland, Antarctica. Named by 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.

Nunatak
A nunatak (from Inuit language, Inuit ) 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 often form natural pyramidal peaks. Isolated nunataks are also called glacial islands, and smaller nunataks rounded by glacial action may be referred to as rognons. The word is of Greenlandic language, Greenlandic origin and has been used in English since the 1870s. Description The term ''nunatak'' is typically used in areas where a permanent ice sheet is present and the ridge protrudes 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 are isolated, they can also form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, hampering the formation of glacial ice on thei ...

Amundsen Glacier
The Amundsen Glacier () is a major Antarctic glacier, about 7 to 11 km (4 to 6 nmi) wide and 150 km (80 nmi) long. It originates on the Antarctic Plateau where it drains the area to the south and west of Nilsen Plateau, then descends through the Queen Maud Mountains to enter the Ross Ice Shelf just west of the MacDonald Nunataks. Name The Amundsen Glacier was discovered by Richard E. Byrd on the South Pole flight in November 1929. The name was proposed for Roald Amundsen by Laurence Gould, leader of the Byrd Antarctic Expedition (Byrd AE) geological party which sledged past the mouth of the glacier in December 1929. Location According to ''Sailing Directions for Antarctica'' (1960), "Lying eastward of the Bowman Glacier is the Amundsen Glacier, the northern portal of which is in 85°30' S., 159°00' W. It is about 6 miles wide and trends southward about 60 miles to the polar plateau. Mount Helmer Hanssen, about 10,742 feet high, is a rounded dome, completel ...

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] |
Amundsen's South Pole Expedition
The first ever expedition to reach the Geographic South Pole was led by the Norwegian explorer Roald Amundsen. He and four other crew members made it to the geographical south pole on 14 December 1911, which would prove to be five weeks ahead of the competitive British party led by Robert Falcon Scott as part of the Terra Nova Expedition. Amundsen and his team returned safely to their base, and about a year later heard that Scott and his four companions had perished on their return journey. Amundsen's initial plans had focused on the Arctic and the conquest of the North Pole by means of an extended drift in an icebound ship. He obtained the use of Fridtjof Nansen's polar exploration ship ''Fram (ship), Fram'', and undertook extensive fundraising in a country that had gained its independence only some Union between Sweden and Norway, six years earlier. Preparations for this expedition were disrupted when, in 1909, the rival American explorers Frederick Cook and Robert Peary ea ...
