Tula Point
Renaud Island is an ice-covered island in the Biscoe Islands of Antarctica, long and from (average ) wide, lying between the Pitt Islands and Rabot Island. It is separated from the Pitt Islands to the northeast by Mraka Sound, and from Lavoisier Island to the southwest by Pendleton Strait. History The Biscoe Islands were discovered in 1832 by a British expedition under John Biscoe and were first roughly surveyed by the French Antarctic Expedition under Jean-Baptiste Charcot, 1903–05 and 1908–10. It was on this second expedition that Renaud Island was first charted and named. Renaud Island was again roughly surveyed in 1935-36 by the British Graham Land Expedition (BGLE). A number of the island's geographical features have been individually charted and named. The majority, except where noted below, were first accurately charted on an Argentine government chart of 1957, and named by the United Kingdom Antarctic Place-Names Committee (UK-APC) during the 1950s.

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] |
Oceanographer
Oceanography (), also known as oceanology and ocean science, is the scientific study of the oceans. It is an Earth science, which covers a wide range of topics, including ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers utilize to glean further knowledge of the world ocean, including astronomy, biology, chemistry, climatology, geography, geology, hydrology, meteorology and physics. Paleoceanography studies the history of the oceans in the geologic past. An oceanographer is a person who studies many matters concerned with oceans, including marine geology, physics, chemistry and biology. History Early history Humans first acquired knowledge of the waves and currents of the seas and oceans in pre-historic times. Observations on ...

UK Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by Scientific Committee on Antarctic Research, SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica.

Hunting Aerosurveys
Hunting Aerosurveys Ltd was a British aerial photography company founded by Percy Hunting in 1944. Its operations became more diversified under the name Hunting Surveys. History The firm incorporated Aerofilms Ltd and the Aircraft Operating Company. In 1947 it was using three types of aircraft: Austers, a Percival Proctor and a de Havilland Dragon Rapide and planned to acquire one or more Percival Mergansers. The company had contracts for work surveying for tin mining in Nigeria; oil in Arabia, Venezuela and Colombia; timber in Ontario; and mapping in Australia & Hong Kong (in 1963). Between 1957 and 1964, Hunting operated a specially converted Auster Autocar for smaller scale aerial survey work. In 1960 the firm was merged with Hunting Geophysics Ltd to form Hunting Surveys Ltd. Threatened with closure in the mid-1980s, it was merged with sister company Hunting Aerofilms Ltd to become simply Aerofilms Ltd in 1987. The new company was able to provide state-of-the-art seri ...

Sea Ice
Sea ice arises as seawater freezes. Because ice is less dense than water, it floats on the ocean's surface (as does fresh water ice, which has an even lower density). Sea ice covers about 7% of the Earth's surface and about 12% of the world's oceans. Much of the world's sea ice is enclosed within the polar ice packs in the Earth's polar regions: the Arctic ice pack of the Arctic Ocean and the Antarctic ice pack of the Southern Ocean. Polar packs undergo a significant yearly cycling in surface extent, a natural process upon which depends the Arctic ecology, including the ocean's ecosystems. Due to the action of winds, currents and temperature fluctuations, sea ice is very dynamic, leading to a wide variety of ice types and features. Sea ice may be contrasted with icebergs, which are chunks of ice shelves or glaciers that calve into the ocean. Depending on location, sea ice expanses may also incorporate icebergs. General features and dynamics Sea ice does not simply grow and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
