Gateway Pass
Gateway Pass () is a mountain pass about long lying between the mountain Astarte Horn and Offset Ridge in eastern Alexander Island, Antarctica. It was mapped by the Directorate of Overseas Surveys from satellite imagery supplied by the U.S. National Aeronautics and Space Administration in cooperation with the U.S. Geological Survey, and was so named by the UK Antarctic Place-Names Committee because the feature serves as a "gateway" giving access to the interior of Alexander Island from the head of Venus Glacier.

Astarte Horn () is a pyramidal peak lying about inland from George VI Sound at the south end of the north-south range extending to Mount Umbriel, in eastern Alexander Island. The feature was mapped from trimetrogon air photography taken by the Ronne Antarctic Research Expedition, 1947–48, and from survey by the Falkland Islands Dependencies Survey, 1948–50, and named by the United Kingdom Antarctic Place-Names Committee in association with nearby Venus Glacier; the goddess Venus being identified with the Phoenician goddess Astarte in mythology Myth is a folklore genre consisting of narratives that play a fundamental role in a society, such as foundational tales or origin myths.

Offset Ridge
Offset Ridge () is a ridge extending west from Triton Point lying between Venus Glacier and Neptune Glacier in eastern Alexander Island, Antarctica. The ridge was mapped by Directorate of Overseas Surveys from satellite imagery by U.S. National Aeronautics and Space Administration in cooperation with U.S. Geological Survey. The ridge is kinked in the middle and is effectively formed of two ridges offset from one another; thus, the descriptive name applied by United Kingdom Antarctic Place-Names Committee (UK-APC).

Alexander Island
Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west.Stewart, J. (2011) ''Antarctic An Encyclopedia'' McFarland & Company Inc, New York. 1776 pp. . Alexander Island is about long in a north–south direction, wide in the north, and wide in the south. Alexander Island is the second-largest uninhabited island in the world, after Devon Island. History Alexander Island was discovered on January 28, 1821, by a Russian expedition under Fabian Gottlieb von Bellingshausen, who named it Alexander I Land for the reigning Tsar Alexander I of Russia.

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] |
Directorate Of Overseas Surveys
The Ordnance Survey International or Ordnance Survey Overseas Directorate its predecessors built an archive of air photography, map and survey records for the United Kingdom from 1946 to 1999. The Ordnance Survey International Collection (formerly the Ordnance Survey International Library) held mapping records that were acquired outside the UK. Although the international division opened in 1946, the OS had been involved in overseas work for almost a century (notably the 1864-65 Ordnance Survey of Jerusalem). The agency was closed in 2001. History The agency In 1946 the ''Directorate of Colonial Surveys'' (DCS) was established by the Colonial Office to provide a central survey and mapping organisation for British colonies and protectorates. In 1957, with the imminent decolonisation of many British territories, it was renamed the ''Directorate of Overseas Surveys'' (DOS). Government reviews during the 1970s led to it being merging into the Ordnance Survey (OS) in 1984 whence it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Aeronautics And Space Administration
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management for ...

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.

Venus Glacier
Venus Glacier () is a glacier on the east coast of Alexander Island, Antarctica, 10 nautical miles (18 km) long and 6 nautical miles (11 km) wide at its mouth flowing east into George VI Sound lying between Keystone Cliffs and Triton Point. The coast in this vicinity was first seen from the air by Lincoln Ellsworth on November 23, 1935 and roughly mapped from photos obtained on that flight by W.L.G. Joerg. The glacier was first surveyed in 1949 by the Falkland Islands Dependencies Survey and named by the United Kingdom Antarctic Place-Names Committee for the planet Venus, the second planet of the Solar System.
