Terminal Peak (Antarctica)
The Ricker Hills () are a group of mainly ice-free hills, about long, lying just west of Hollingsworth Glacier in Antarctica. They were mapped and named by the Southern Party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1962–63, for J.F. Ricker, a geologist with the party. Location The Ricker Hills are just west of the Hollingsworth Glacier, which flows along their east side, and south of the David Glacier. The Antarctic Plateau The Antarctic Plateau, Polar Plateau or King Haakon VII Plateau is a large area of East Antarctica that extends over a diameter of about , and includes the region of the geographic South Pole and the Amundsen–Scott South Pole Station.

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 78th parallel south, 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 Victoria of the United Kingdom, 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. History Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 Meteorite, meteorites in Antarctica, some of which were found near the Allan Hills in Victoria Land. The meteorites appeared to have undergone little change since they were formed at what scientists believe was the birth of the Solar System. In 1981, Lichen, lichens fo ...

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic 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 Climate of Antarctica#Precipitation, 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 temperature recorded on Earth, lowest measured temperature on Earth, . The coastal regions can reach temperatures over in the ...

Prince Albert Mountains
The Prince Albert Mountains () are a major mountain group in Antarctica over long. Located in Victoria Land, they run north–south between the Priestley Glacier to the north and Ferrar Glacier to the south. They are south of the Deep Freeze Range and north of the Kirkwood Range. Exploration and name The Prince Albert Mountains were discovered by Sir James Clark Ross, on February 17, 1841, and named by him for Prince Albert, the consort of the British Queen Victoria of England. The first exploration of the mountains was by British expeditions in the early 1900s. Detailed survey and mapping was accomplished by New Zealand and American expeditions in the 1950s and 1960s. Location The northeastern section of the Prince Albert Mountains extends across the Reeves Glacier north to the Priestley Glacier. These two glacier converge into the Nansen Ice Sheet. Further south, they cross the David Glacier and Larsen Glacier. In the far south they extend to the Mawson Glacier. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hollingsworth Glacier
The David Glacier () is a glacier over long, flowing east from the polar plateau through the Prince Albert Mountains to the coast of Victoria Land, Antarctica. It enters Ross Sea between Cape Philippi and Cape Reynolds to form the floating Drygalski Ice Tongue. It is the most imposing outlet glacier in Victoria Land. It is fed by two main flows which drain an area larger than 200,000 square kilometres, with an estimated ice discharge rate of 7.8 +/- 0.7 km3/year. The David Glacier was discovered by Ernest Shackleton's "Northern Party," in November 1908, under the leadership of Prof. T.W. Edgeworth David, of Sydney University, for whom the feature was named. Location The David Glacier flows eastward in a broad stream that gradually narrows towards the coast. The northern flow drains from Talos Dome to the Ross Sea, but the main branch of the stream is fed by a network of tributaries which drain a common area of the inner plateau around Dome C and converge in a spectacular ...

Antarctic Plateau
The Antarctic Plateau, Polar Plateau or King Haakon VII Plateau is a large area of East Antarctica that extends over a diameter of about , and includes the region of the geographic South Pole and the Amundsen–Scott South Pole Station. This huge continental plateau is at an average elevation of about . Exploration This plateau was first sighted in 1903 during the '' Discovery'' Expedition to the Antarctic, which was led by Robert Falcon Scott. Ernest Shackleton became the first to cross parts of this plateau in 1909 during his '' Nimrod'' Expedition, which turned back in bad weather when it had reached a point from the South Pole. Shackleton named this plateau the King Edward VII Plateau in honour of the king of the United Kingdom. In December 1911, while returning from the first journey to the South Pole, the Norwegian explorer Roald Amundsen decided to name this plateau the King Haakon VII Plateau in honour of the newly elected king of Norway.

Mawson Glacier
The Mawson Glacier () is a large glacier on the east coast of Victoria Land, Antarctica, descending eastward from the Antarctic Plateau to the north of Trinity Nunatak and the Kirkwood Range, to enter the Ross Sea, where it forms the Nordenskjöld Ice Tongue. The glacier was first mapped by the British Antarctic Expedition (1907–09) and named for Douglas Mawson, the expedition physicist, who later led two other Antarctic expeditions, 1911–14, and 1929–31. Glaciology After the Last Glacial Maximum (LGM) there was dynamic retreat of the ice sheet covering the Ross Sea in the Mawson Glacier region. The glacier thinned abruptly between 7,500 and 4,500 years ago, then thinned more gradually until recently. This thinning was very similar to what happened at the Mackay Glacier to the south. Probably the ice sheet retreat and glacial ice drawdown were caused by ocean warming. Course The Mawson Glacier rises on the Antarctic Plateau. Features of the region of its head include ...
