Damocles Point
Damocles Point () is a headland on the east coast of Alexander Island, east-southeast of the south summit of Mount Tyrrell. A small rock exposure near sea level is surmounted by a ice cliff. The headland is adjacent to George VI Sound and is facing towards the Rymill Coast in Palmer Land. It was first photographed from the air in 1937 by the British Graham Land Expedition under Rymill. It was surveyed in 1948 by the Falkland Islands Dependencies Survey, and so named by them because the ice cliff overhanging the spot where geological specimens were collected seemed like the sword of Damocles Damocles is a character who appears in an (likely apocryphal) anecdote commonly referred to as "the sword of Damocles", an allusion to the imminent and ever-present peril faced by those in positions of power.

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.

Mount Tyrrell
Mount Tyrrell () is an irregular mountain with two summits, the highest rising to a maximum height of , standing 3 nautical miles (6 km) inland from the east coast of Alexander Island, Antarctica, situated on the east side and near the mouth of Toynbee Glacier. The mountain was first photographed from the air in 1937 by the British Graham Land Expedition under Rymill. The mountain was surveyed in 1948 by the Falkland Islands Dependencies Survey and was named by them for George Walter Tyrrell, British geologist at the University of Glasgow, Scotland.

George VI Sound
George VI Sound or Canal Jorge VI or Canal Presidente Sarmiento or Canal Seaver or King George VI Sound or King George the Sixth Sound is a major bay/ fault depression, 300 miles (483 km) long and mainly covered by a permanent ice shelf. It is in the shape of the letter J without any upper bar. It lines the east and south shores of Alexander Island, separating it from the vestigial, quite small, Wordie Ice Shelf and Palmer Land (the south-west of the Antarctic Peninsula) and the north-facing "English Coast". A quite central point of it is . Various lakes adjoin; these receive large amounts of melt ice from the George VI Ice Shelf. These include Hodgson, Moutonee and Ablation Lakes. Several glaciers flow eastward into the sound from the east interior of Alexander Island, the vast majority of these glaciers are south of Planet Heights, where all of these glaciers are named after moons, satellites and planets of the Solar System in the same vein as the Heights, named by the ...

Rymill Coast
Rymill Coast is that portion of the west coast of Antarctic Peninsula between Cape Jeremy and Buttress Nunataks. It runs northward from English Coast and east of Alexander Island across George VI Sound, encompassing the Batterbee Mountains. It is joined in the north by Fallieres Coast, which runs along Marguerite Bay. It was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1985 after John Riddoch Rymill (1905–68), Australian leader of the BGLE, 1934–37. The coast was partially photographed from the air by Lincoln Ellsworth, November 23, 1935. It was further photographed from the air and surveyed by British Graham Land Expedition (BGLE) in October–November 1936. The area was further surveyed by United States Antarctic Service (USAS), 1940, and by Falkland Islands Dependencies Survey (FIDS), 1948–50. Additional aerial photography was done by the Ronne Antarctic Research Expedition (RARE), 1947, and U.S. Navy The United States Navy (USN) is ...

Palmer Land
Palmer Land () is the portion of the Antarctic Peninsula, Antarctica that lies south of a line joining Cape Jeremy and Cape Agassiz. This application of Palmer Land is consistent with the 1964 agreement between the Advisory Committee on Antarctic Names and the UK Antarctic Place-Names Committee, 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° S. Boundaries In its southern extreme, the Antarctic Peninsula stretches west, with Palmer Land eventually bordering Ellsworth Land along the 80° W line of longitude. Palmer Land is bounded in the south by the ice-covered Carlson Inlet, an arm of the Filchner-Ronne Ice Shelf, which crosses the 80° W line. This is the base of Cetus Hill. This feature is named after Nathaniel Palmer, an American sealer who explored the Antarctic Peninsula area southward of Deceptio ...

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. At the end of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Damocles
Damocles is a character who appears in an (likely apocryphal) anecdote commonly referred to as "the sword of Damocles", an allusion to the imminent and ever-present peril faced by those in positions of power. Damocles was a courtier in the court of Dionysius II of Syracuse, a 4th-century BC ruler of Syracuse, Sicily. The anecdote apparently figured in the lost history of Sicily by Timaeus of Tauromenium (). The Roman orator Cicero () may have read it in the texts of Greek historian Diodorus Siculus and used it in his ''Tusculanae Disputationes'', 5. 61, by which means it passed into the European cultural mainstream. Sword of Damocles According to the story, Damocles was pandering to his king, Dionysius, exclaiming that Dionysius was truly fortunate as a great man of power and authority without peer, surrounded by magnificence. In response, Dionysius offered to switch places with Damocles for one day so that Damocles could taste that very fortune firsthand. Damocles quickly an ...
