Overturn Glacier
Darwin Glacier () is a large glacier in Antarctica. It flows from the polar plateau eastward between the Darwin Mountains and the Cook Mountains to the Ross Ice Shelf. The lower part of the glacier was mapped by the British National Antarctic Expedition, 1901–04, and the whole area traversed by New Zealand parties of the Commonwealth Trans-Antarctic Expedition (1956–58). The glacier was named in association with the Darwin Mountains (themselves named after Leonard Darwin). Robertson Buttress is the westernmost in a series of large rock buttresses on the south side of Darwin Glacier between Alley Glacier and Gaussiran Glacier.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alley Glacier
The Alley Glacier () is a glacier in Antarctica that drains the north slopes of Britannia Range in the vicinity of Ward Tower and flows north to Darwin Glacier. It is separated from Gaussiran Glacier by a series of large rock buttresses, including Robertson Buttress. It was named by the Advisory Committee on Antarctic Names after Richard Alley of the Department of Geosciences, Pennsylvania State University, a United States Antarctic Program glaciologist who specialized in the study of ice streams of the West Antarctic Ice Sheet.

Glaciology
Glaciology (; ) is the scientific study of glaciers, or more generally ice and natural phenomena that involve ice. Glaciology is an interdisciplinary Earth science that integrates geophysics, geology, physical geography, geomorphology, climatology, meteorology, hydrology, biology, and ecology. The impact of glaciers on people includes the fields of human geography and anthropology. The discoveries of water ice on the Moon, Mars, Europa and Pluto add an extraterrestrial component to the field, which is referred to as "astroglaciology". Overview A glacier is an extended mass of ice formed from snow falling and accumulating over a long period of time; glaciers move very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of accumulation, as in continental glaciers. Areas of study within glaciology include glacial history and the reconstruction of past glaciation. A glaciologist is a person who studies glaciers. A glacial geologist ...

List Of Glaciers In The Antarctic
There are many glaciers in the Antarctic. This set of lists does not include ice sheets, ice caps or ice fields, such as the Antarctic ice sheet, but includes glacial features that are defined by their flow, rather than general bodies of ice. The lists include outlet glaciers, valley glaciers, cirque glaciers, tidewater glaciers and ice streams. Ice streams are a type of glacier and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined as any latitude further south than 60° (the continental limit according to the Antarctic Treaty System).

Erewhon Basin
Erewhon Basin () is an extensive ice-free area in Antarctica. It forms a basin in the Brown Hills separating the snouts of Foggydog Glacier and Bartrum Glacier from the northern edge of the Darwin Glacier. It was explored by the Victoria University of Wellington Antarctic Expedition), 1962–63, and named from Samuel Butler's novel ''Erewhon ''Erewhon: or, Over the Range'' () is a novel by English writer Samuel Butler, first published anonymously in 1872, set in a fictional country discovered and explored by the protagonist.

Gaussiran Glacier
Gaussiran Glacier is a glacier in the eastern part of the Britannia Range, Antarctica. It drains north from the saddle with Merrick Glacier to a juncture with Darwin Glacier between the Cranfield Icefalls and the Nebraska Peaks. It is separated from Alley Glacier by a series of large rock buttresses, including Robertson Buttress. It was named by the Advisory Committee on Antarctic Names after Lieutenant C.D. Gaussiran, U.S. Navy, a pilot with the VXE-6 detachment at Darwin Glacier Field Camp, 1978–79.

Robertson Buttress
Robertson Buttress () is the westernmost (1040 m) in a series of large rock buttresses on the south side of Darwin Glacier between Alley Glacier and Gaussiran Glacier.

Ross Dependency
The Ross Dependency is a region of Antarctica defined by a sector originating at the South Pole, passing along longitudes 160° east to 150° west, and terminating at latitude 60° south. It is claimed by New Zealand, a claim accepted only by the other six countries with territorial claims in Antarctica. Under the 1961 Antarctic Treaty, of which all territorial claimants are signatories, including New Zealand, all claims are held in abeyance. Article IV states: "No acts or activities taking place while the present Treaty is in force shall constitute a basis for asserting, supporting or denying a claim to territorial sovereignty in Antarctica or create any rights of sovereignty in Antarctica". The Dependency takes its name from Sir James Clark Ross, who discovered the Ross Sea, and includes part of Victoria Land, and most of the Ross Ice Shelf. Ross, Balleny, Scott and Roosevelt Islands also form part of the Dependency. History of claim Following his discovery of Victo ...

He went on several scientific expeditions, including those to observe the Tran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commonwealth Trans-Antarctic Expedition
The Commonwealth Trans-Antarctic Expedition (CTAE) of 1955–1958 was a Commonwealth-sponsored expedition that successfully completed the first overland crossing of Antarctica, via the South Pole. It was the first expedition to reach the South Pole overland for 46 years, preceded only by Amundsen's expedition and Scott's expedition in 1911 and 1912. In keeping with the tradition of polar expeditions of the Heroic Age of Antarctic Exploration, the CTAE was a private venture, though it was supported by the governments of the United Kingdom, New Zealand, United States, Australia and South Africa, as well as many corporate and individual donations, under the patronage of Queen Elizabeth II. It was headed by British explorer Vivian Fuchs, with New Zealander Sir Edmund Hillary leading the New Zealand Ross Sea Support team. The New Zealand party included scientists participating in International Geophysical Year research while the British team were separately based at Halley Ba ...
