Wallabies Nunataks
Wallabies Nunataks () is a large group of nunataks near the polar plateau, lying 10 nautical miles (18 km) northeast of All-Blacks Nunataks at the east side of the Byrd Neve. Named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE) (1960–61) for the Australian national rugby team.

Churchill Mountains
The Churchill Mountains are a mountain range group of the Transantarctic Mountains System, located in the Ross Dependency region of Antarctica. They border on the western side of the Ross Ice Shelf, between Byrd Glacier and Nimrod Glacier. Several of the range's highest summits, including Mounts Egerton, Field, Nares, Wharton, and Albert Markham were first seen and named by the Discovery Expedition of 1901–1904 (aka: British National Antarctic Expedition), under Robert Falcon Scott The mountains were mapped in detail by the USGS from Tellurometer surveys during 1960–61, and by United States Navy air photos in 1960. They were named by the US-ACAN for Sir Winston Churchill.

Oates Land
Oates Land is a region of Antarctica. It is variously defined as a portion of the East Antarctica near the coast stretching along and inland from the Oates Coast (see map) and as an officially delineated wedge-shaped segment of the Australian Antarctic Territory. The segment of the Australian claim extends between 153°45' E and 160° E, forming a wedge between Latitude 60° S and the South Pole. It is bounded in the east by the Ross Dependency and overlaps George V Land to the west. Exploration Oates Land was discovered in February 1911 by Lieutenant Harry Pennell of the Royal Navy, commander of the '' Terra Nova'', the expedition ship of the British Antarctic Expedition, 1910–13. It is named after Captain Lawrence Edward Grace "Titus" Oates of the 6th (Iniskilling) Dragoons, who, with Captain Robert Falcon Scott and three companions, lost his life on the return journey from the South Pole in 1912.Geographic Names Information System,Oates Land, United States Geological Surv ...

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] |
Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Cape Hallett
Cape Hallett is a snow-free area (Antarctic oasis) on the northern tip of the Hallett Peninsula on the Ross Sea coast of Victoria Land, East Antarctica. Cape Adare lies to the north. History In 1956, during Operation Deep Freeze II, was damaged by an ice floe at Cape Hallett. Hallett Station The cape was the location of a joint scientific base, Hallett Station, between the United States and New Zealand during the International Geophysical Year of 1957, and was manned permanently until 1964, when there was a major fire. It was then used as a summer only base until 1973. The site is currently being remediated by removing hazardous materials: fuel, and oil stored in several large tanks. This is an ongoing project which will take several years to complete. Antarctic Specially Protected Area An area of 74 ha is protected under the Antarctic Treaty System as Antarctic Specially Protected Area (ASPA) No.106 because it contains habitats with a rich and diverse range of ...

Earth's Magnetic Field
Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun. The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo. The magnitude of Earth's magnetic field at its surface ranges from . As an approximation, it is represented by a field of a magnetic dipole currently tilted at an angle of about 11° with respect to Earth's rotational axis, as if there were an enormous bar magnet placed at that angle through the center of Earth. The North geomagnetic pole actually represents the South pole of Earth's magnetic field, and conversely the South geomagnetic pole corresponds to the north pole of Earth's magnetic ...
