Kaka Nunatak
Mount Bird is a high shield volcano standing about south of Cape Bird, the northern extremity of Ross Island. It was mapped by the British National Antarctic Expedition, 1901–04, under Robert Falcon Scott, and apparently named by them after Cape Bird. Endeavour Piedmont Glacier lies on its slopes. There are several western lobes of the Mount Bird icecap. One of these is Quaternary Icefall, which descends steeply into Wohlschlag Bay 1 mile (1.6 km) south of Cinder Hill. The site was mapped and so named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1958–59, because of the Quaternary glacial period marine shells carried by the glacier and deposited in terminal moraines. Another such lobe is Shell Glacier. See also *List of volcanoes in Antarctica This is a list of volcanoes in Antarctica.

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] |
Wohlschlag Bay
Wohlschlag Bay () is a large bay indenting the western side of Ross Island, Antarctica, and lying between Harrison Bluff and Cape Royds. It was first charted by the Discovery Expedition under Robert Falcon Scott, 1901–1904, then named by the Advisory Committee on Antarctic Names (US-ACAN) in 1964 for Donald E. Wohlschlag, professor of biology at Stanford University, who outfitted the biology laboratories on the USNS Eltanin and at McMurdo Station. Romanes Beach Romanes Beach is a beach on the north shore of Wohlschlag Bay, just south of Harrison Bluff. It was mapped by a party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1958–59, landed there by the . It was named by the New Zealand Antarctic Place-Names Committee (NZ-APC) for W. Romanes, mountaineer assistant with the expedition. Maumee Bight The southern part of the bay is formed by Maumee Bight, a long bight between Rocky Point and Micou Point. In association with the names of expediti ...

Volcanoes Of Ross Island
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...

American Geophysical Union
The American Geophysical Union (AGU) is a 501(c)(3) nonprofit organization of Earth, atmospheric, ocean, hydrologic, space, and planetary scientists and enthusiasts that according to their website includes 130,000 people (not members). AGU's activities are focused on the organization and dissemination of scientific information in the interdisciplinary and international fields within the Earth and space sciences. The geophysical sciences involve four fundamental areas: atmospheric and ocean sciences; solid-Earth sciences; hydrologic sciences; and space sciences. The organization's headquarters is located on Florida Avenue in Washington, D.C. History The AGU was established in December 1919 by the National Research Council (NRC) to represent the United States in the International Union of Geodesy and Geophysics (IUGG), and its first chairman was William Bowie of the United States Coast and Geodetic Survey (USCGS). For more than 50 years, it operated as an unincorporated affili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Endeavour Piedmont Glacier
Endeavour Piedmont Glacier is a piedmont glacier, long and wide, between the southwest part of Mount Bird and Micou Point, Ross Island. In association with the names of expedition ships grouped on this island, it was named after HMNZS Endeavour (A184), HMNZS ''Endeavour'', a tanker/supply ship which for at least 10 seasons, 1962–63 to 1971–72, transported bulk petroleum products and cargo to Scott Base and McMurdo Station on Ross Island.

Continent
A continent is any of several large landmasses. Generally identified by convention rather than any strict criteria, up to seven geographical regions are commonly regarded as continents. Ordered from largest in area to smallest, these seven regions are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia. "Most people recognize seven continents—Asia, Africa, North America, South America, Antarctica, Europe, and Australia, from largest to smallest—although sometimes Asia and Europe are considered a single continent, Eurasia." Variations with fewer continents may merge some of these, for example America, Eurasia, or Afro-Eurasia are sometimes treated as single continents, which can bring the total number as low as four. Zealandia, a largely submerged mass of continental crust, has also been described as a continent. Oceanic islands are frequently grouped with a nearby continent to divide all the world's land into geographical regions. Under t ...
