Castor Rock () is the northern of a pair of large off-lying rocks south of Vindication Island, South Sandwich Islands. This rock, with its neighbor Pollux Rock, was named "Castor and Pollux", after the Dioscuri of Greek mythology, during the survey of these islands from RRS ''Discovery II'' in 1930. In 1971 the 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) an ... recommended that they be assigned unambiguous names making each individually identifiable, and this has been done by naming the northern one Castor Rock and the southern one Pollux Rock.

Vindication Island
Vindication Island is a small uninhabited island of the Candlemas Islands in the South Sandwich Islands. It is one of about a dozen islands that make up the South Sandwich island arc, a chain of volcanoes in the Southern Ocean that was discovered in 1775 by James Cook. The volcanism is caused by the subduction of the South American Plate beneath the Sandwich Plate. The island has a rectangular outline and is the remnant of three mostly eroded volcanoes. The highest point of the island, Quadrant Peak, directly overlies the coast. Inland Vindication Island features a rich vegetation, consisting of lichens and mosses, while various bird and penguin species breed along the coasts. There is no evidence of recent volcanic activity. History and toponymy Vindication and Candlemas Island were both discovered on 2 February 1775 by James Cook aboard . In 1951–1952 the Argentine frigates and installed a marker on Vindication, claiming Argentine sovereignty over the island; this is t ...

South Sandwich Islands
The South Sandwich Islands () are a chain of uninhabited volcanic islands in the South Atlantic Ocean. They are administered as part of the British Overseas Territory of South Georgia and the South Sandwich Islands. The chain lies in the sub-Antarctic region, about southeast of South Georgia and northeast from the tip of the Antarctic Peninsula. The archipelago comprises 11 main islands forming an island arc running north–south, the largest being Montagu at . It is divided into four groups, from north to south: The Traversay, Candlemas and Central Islands ( Saunders, Montagu, and Bristol), and Southern Thule. The archipelago is prone to violent earthquakes. Over the previous century, nine M 7+ earthquakes have occurred here, the most recent being the M 8.1 in August 2021. None of these earthquakes are known to have caused fatalities due to their remote location. History The southern eight islands of the South Sandwich Islands were discovered by Captain ...

Dioscuri
Castor and Pollux (or Polydeuces) are twin half-brothers in Greek mythology, Greek and Roman mythology, known together as the Dioscuri or Dioskouroi. Their mother was Leda (mythology), Leda, but they had different fathers; Castor was the mortal son of Tyndareus, the king of Sparta, while Pollux was the divine son of Zeus, who seduced Leda in the guise of a swan. The pair are thus an example of heteropaternal superfecundation. Though accounts of their birth are varied, they are sometimes said to have been born from an egg, along with their twin sisters Helen of Troy and Clytemnestra. In Latin, the twins are also known as the Gemini ("twins") or Castores, as well as the Tyndaridae or Tyndarids. Pollux asked Zeus to let him share his own immortality with his twin to keep them together, and they were transformed into the constellation Gemini (constellation), Gemini. The pair were regarded as the patrons of sailors, to whom they appeared as St. Elmo's fire. They were also associated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RRS Discovery II
RRS ''Discovery II'' was a British Royal Research Ship which, during her operational lifetime of about 30 years, carried out considerable hydrographical and marine biological survey work in Antarctic waters and the Southern Ocean in the course of the Discovery Investigations research program. Built in Port Glasgow, launched in 1928 and completed in 1929, she was the first purpose-built oceanographic research vessel and was named after Robert Falcon Scott's 1901 ship, RRS ''Discovery''. Career The ship's maiden voyage took place from December 1929 to May 1931 and consisted of a hydrographic survey of the South Sandwich Islands. From October 1932 until May 1933 she operated in the Antarctic, calling at South Africa, Australia and New Zealand. Similar voyages took place from 1934 to 1939 during which she supplied the British Graham Land expedition. Her last voyage before the onset of war was from September 1937 to May 1939. In December 1935 and January 1936, the ship was inv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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. Names attributed by the committee * Anvil Crag, named for descriptive features * Anckorn Nunataks, named after J. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
