Mount Rhamnus
Mount Rhamnus () is a mountain in Antarctica. It is 865 meters tall and lies 2 nautical miles (3.7 km) northeast of Mount Nemesis on the north side of Neny Fjord, Graham Land. Seen from the west, it appears as a mainly snow-covered pyramid. First surveyed in 1936 by the British Graham Land Expedition (BGLE) under Rymill. Resurveyed in 1947 by the Falkland Islands Dependencies Survey The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute.

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 ...

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] |
Mount Nemesis
Mount Nemesis () is a mountain, 790 m, which lies 2 nautical miles (3.7 km) northeast of the seaward extremity of Roman Four Promontory and close north of Neny Fjord, on the west coast of Graham Land. First surveyed in 1936 by the British Graham Land Expedition (BGLE) under Rymill. The name is believed to have been given by members of the United States Antarctic Service The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the A ...

Neny Fjord
Neny Fjord is a fjord which is long in an east–west direction and wide, between Red Rock Ridge and Roman Four Promontory on the west coast of Graham Land, Antarctica. Geography * Mount Dudley History This coast was first explored in 1909 by Jean-Baptiste Charcot who, it appears, gave this name to a feature somewhat north of the bay described. The British Graham Land Expedition (BGLE) made a detailed survey of this area in 1936–1937, and in correlating their work with that of Charcot applied the name Neny Fjord to the bay between Red Rock Ridge and Roman Four Promontory. The name has become established in this latter position through international acceptance and use.

Graham Land
Graham Land is the portion of the Antarctic Peninsula that lies north of a line joining Cape Jeremy and Cape Agassiz. This description of Graham Land is consistent with the 1964 agreement between the British Antarctic Place-names Committee and the US Advisory Committee on Antarctic Names, in which the name "Antarctic Peninsula" was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69 degrees south. Graham Land is named after Sir James R. G. Graham, First Lord of the Admiralty at the time of John Biscoe's exploration of the west side of Graham Land in 1832. It is claimed by Argentina (as part of Argentine Antarctica), Britain (as part of the British Antarctic Territory) and Chile (as part of the Chilean Antarctic Territory). Graham Land is the closest part of Antarctica to South America. Thus it is the usual destination for small ships taking paying ...

Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.

Rhamnous
Rhamnous ( grc, Ῥαμνοῦς, Rhamnoûs; el, Ραμνούς, Ramnoús, label=Modern Greek), also Ramnous or Rhamnus, was an ancient Greek city in Attica situated on the coast, overlooking the Euboean Strait. Its impressive ruins lie northwest of the modern town of Agia Marina in the municipality of Marathon. The site was best known in antiquity for its sanctuary of Nemesis, the implacable avenging goddess, her most important in ancient Greece. Rhamnous is the best-preserved Attic deme site. It was strategically significant on the sea routes and was fortified with an Athenian garrison of ''ephebes'' (young men). A fortified acropolis dominates the two small harbours located on either side of it which have silted up extensively since antiquity, and into which grain was imported for Athens during the Peloponnesian War. History Rhamnus or Rhamnous ( grc, Ῥαμνοῦς) or Rhamnuntus or Rhamnountos (Ῥαμνοῦντος) was a deme of ancient Attica, belonging to the trib ...
