Nansen Ice Sheet
Nansen Ice Sheet (), or Nansen Ice Shelf, is a by ice shelf. It is nourished by the Priestley and Reeves Glaciers and abutting the north side of the Drygalski Ice Tongue, along the coast of Victoria Land, Antarctica. This feature was explored by the South Magnetic Polar Party of the British Antarctic Expedition, 1907-09 and by the Northern Party of the British Antarctic Expedition, 1910-13. Frank Debenham, geologist with the latter expedition, applied the name Nansen Sheet as the feature is adjacent to Mount Nansen, the dominating summit in the area.

Ice Shelf
An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland, Northern Canada, and the Russian Arctic. The boundary between the floating ice shelf and the anchor ice (resting on bedrock) that feeds it is the grounding line. The thickness of ice shelves can range from about to . In contrast, sea ice is formed on water, is much thinner (typically less than ), and forms throughout the Arctic Ocean. It is also found in the Southern Ocean around the continent of Antarctica. The movement of ice shelves is principally driven by gravity-induced pressure from the grounded ice. That flow continually moves ice from the grounding line to the seaward front of the shelf. In steady state, about half of Antarctica's ice shelf mass is lost to basal melt and half is lost to calving, but the relative importance of each process varies significantly between ice s ...

Priestley Glacier
The Priestley Glacier is a major valley glacier, about long, originating at the edge of the Polar Plateau of Victoria Land, Antarctica. The glacier drains southeast between the Deep Freeze and Eisenhower Ranges to enter the northern end of the Nansen Ice Sheet. It was first explored by the Northern Party of the British Antarctic Expedition, 1910–13, and named for Raymond E. Priestley, a geologist with the Northern Party. Priestley Névé () is the névé at the head of Priestley Glacier in Victoria Land. It was named by the 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.

Reeves Glacier
Reeves Glacier () is a broad glacier originating on the interior upland and descending between Eisenhower Range and Mount Larsen to merge with the Nansen Ice Sheet along the coast of Victoria Land. Discovered and named by the British Antarctic Expedition, 1907–09, under Shackleton. The New Zealand Antarctic Place-Names Committee (NZ-APC) reported that the glacier is probably named for William Pember Reeves, former New Zealand New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean.

Drygalski Ice Tongue
The Drygalski Ice Tongue, Drygalski Barrier, or Drygalski Glacier Tongue is a glacier in Antarctica, on the Scott Coast, in the northern McMurdo Sound of Ross Dependency, north of Ross Island. The Drygalski Ice Tongue is stable by the standards of Antarctica's icefloes, and stretches out to sea from the David Glacier, reaching the sea from a valley in the Prince Albert Mountains of Victoria Land. The Drygalski Ice Tongue ranges from wide. Captain Robert Falcon Scott, leader of the British National Antarctic Expedition (1901-1904), discovered the Drygalski Ice Tongue in January 1902 and named it for Professor Erich von Drygalski, a contemporary German explorer then in Antarctica. The glacier that feeds the ice tongue was named after Edgeworth David. David and Douglas Mawson crossed the ice tongue in 1908/09 as part of the ''Nimrod'' Expedition. The ''Terra Nova'' Northern Party expedition did the same in 1912 during their return journey to Cape Evans. The name Drygalski Ice T ...

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] |
Nimrod Expedition
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. Its main target, among a range of geographical and scientific objectives, was to be first to the South Pole. This was not attained, but the expedition's southern march reached a Farthest South latitude of 88° 23' S, just from the pole. This was by far the longest southern polar journey to that date and a record convergence on either Pole. A separate group led by Welsh Australian geology professor Edgeworth David reached the estimated location of the South Magnetic Pole, and the expedition also achieved the first ascent of Mount Erebus, Antarctica's second highest volcano. The expedition lacked governmental or institutional support, and relied on private loans and individual contributions. It was beset by financial problems and its preparations ...

Terra Nova Expedition
The ''Terra Nova'' Expedition, officially the British Antarctic Expedition, was an expedition to Antarctica which took place between 1910 and 1913. Led by Captain Robert Falcon Scott, the expedition had various scientific and geographical objectives. Scott wished to continue the scientific work that he had begun when leading the ''Discovery'' Expedition from 1901 to 1904, and wanted to be the first to reach the geographic South Pole. He and four companions attained the pole on 17 January 1912, where they found that a Norwegian team led by Roald Amundsen had preceded them by 34 days. Scott's party of five died on the return journey from the pole; some of their bodies, journals, and photographs were found by a search party eight months later. The expedition, named after its supply ship, was a private venture financed by public contributions and a government grant. It had further backing from the Admiralty, which released experienced seamen to the expedition, and from the Royal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and locative information about more than two million physical and cultural features throughout the United States and its territories, Antarctica, and the associated states of the Marshall Islands, Federated States of Micronesia, and Palau. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
