John Peaks
The John Peaks () are prominent snow-covered peaks, high, at the southern end of Coronation Island, north of Powell Island and east of Signy Island in the South Orkney Islands. They were probably first sighted by Captain George Powell and Captain Nathaniel Palmer, who discovered these islands in December 1821. The peaks were charted in 1933 by Discovery Investigations personnel on the ''Discovery II'' who named them for D.D.

Coronation Island
Coronation Island is the largest of the South Orkney Islands, long and from wide. The island extends in a general east–west direction, is mainly ice-covered and comprises numerous bays, glaciers and peaks, the highest rising to . History The island was discovered in December 1821, in the course of the joint cruise by Captain Nathaniel Palmer, an American sealer, and Captain George Powell, a British sealer. Powell named the island in honour of the coronation of George IV, who had become king of the United Kingdom in 1820. Antarctic Specially Protected Area An area of some 92 km2 of north-central Coronation Island has been designated an Antarctic Specially Protected Area (ASPA 114), mainly for use as a relatively pristine reference site for use in comparative studies with more heavily impacted sites. It extends northwards from Brisbane Heights and Wave Peak in the central mountains to the coast between Conception Point in the west to Foul Point in the east. Most of ...

Powell Island
Powell Island is a narrow island long and wide, lying between Coronation and Laurie Islands in the central part of the South Orkney Islands of Antarctica. Its southern end lies 7 km east of the south-western extremity of Coronation Island, between Lewthwaite Strait and Washington Strait. History The island was discovered in the course of the joint cruise by Captains George Powell and Nathaniel Palmer in December 1821. It was correctly charted, though unnamed, on Powell's map published in 1822; it was subsequently named for Powell on an Admiralty chart of 1839. Birds An area including part of southern Powell Island (south of John Peaks on Coronation Island), along with neighbouring Christoffersen, Fredriksen, Michelsen and Grey Islands, with some other (unnamed) islands lying offshore, has been identified as a 2688 ha Important Bird Area (IBA) by BirdLife International as it supports several significant seabird breeding colonies. The boundary of the IBA is defin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Signy Island
Signy Island is a small subantarctic island in the South Orkney Islands of Antarctica. It was named by the Norwegian whaler Petter Sørlle (1884–1933) after his wife, Signy Therese. The island is about long and wide and rises to above sea level. Much of it is permanently covered with ice. The average temperature range is to about in winter (i.e. in July). The extremes extend to . It is separated from Coronation Island to the north by Normanna Strait, and from Moe Island to the southwest by Fyr Channel. On Signy Island, the British Antarctic Survey (BAS) maintains the Signy Research Station, a scientific station for research in biology. The base was opened on 18 March 1947, on the site of an earlier whaling station that had existed there in the 1920s. The station was staffed year-round until 1996; since that year it has been occupied only from November to April. It houses 10 people.

George Powell (mariner)
George Powell (1794–1824) was an English sealer, explorer and amateur naturalist. He captained three sealing expeditions to the Antarctic Ocean between 1818 and 1822. Powell was born in London. During his first expedition, in 1818 and 1819, he captained the sloop ''Dove'' and visited South Georgia and Kerguelen Islands. His second expedition, captaining ''Eliza'', lasted from 1819 until 1821, during which time he visited the Falkland Islands and the South Shetland Islands. In 1821 and 1822 he took both ''Dove'', which he captained, and ''Eliza'', captained by John Wright, on another sealing expedition to the South Shetland Islands, for which he produced a very fine chartL.

Nathaniel Palmer
Nathaniel Brown Palmer (August 8, 1799June 21, 1877) was an American seal hunter, explorer, sailing captain, and ship designer. He gave his name to Palmer Land, Antarctica, which he explored in 1820 on his sloop ''Hero''. He was born in Stonington, Connecticut, and was a descendant of Walter Palmer, one of the town's founders. Sealing career and Antarctic exploration During the 1810s the hides of Antarctic Ocean seals were highly valued as items for trade with China. Palmer served as second mate on board s first voyage, during which she became the first American vessel known to reach the South Shetland Islands. As a skilled and fearless seal hunter, Palmer achieved his first command at the early age of 21. His vessel, a diminutive sloop named , was only in length. Palmer steered southward in ''Hero'' at the beginning of the Antarctic summer of 1820–1821. Aggressively searching for new seal rookeries south of Cape Horn, on November 17, 1820, Palmer and his men became the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discovery Investigations
The Discovery Investigations were a series of scientific cruises and shore-based investigations into the biology of whales in the Southern Ocean. They were funded by the British Colonial Office and organised by the Discovery Committee in London, which was formed in 1918. They were intended to provide the scientific background to stock management of the commercial Antarctic whale fishery. The work of the Investigations contributed hugely to our knowledge of the whales, the krill they fed on, and the oceanography of their habitat, while charting the local topography, including Atherton Peak. The investigations continued until 1951, with the final report being published in 1980. Laboratory Shore-based work on South Georgia took place in the marine laboratory, Discovery House, built in 1925 at King Edward Point and occupied until 1931. The scientists lived and worked in the building, travelling half a mile or so across King Edward Cove to the whaling station at Grytviken to work on w ...

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 invo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discovery Committee
The Discovery Committee was a popular name for the Interdepartmental Committee for the Dependencies of the Falkland Islands established by the British Government to carry out scientific investigations (which became known as ‘Discovery Investigations’) and to propose nature resource conservation and economic development policies for the Falkland Islands Dependencies. During more than 25 years (1925–51) of pioneering work, the Committee's research ships ( Robert Scott’s ship), and collected an enormous amount of oceanographic, biological, and geographical data published in 38 volumes, contributing greatly to the knowledge of the world's southern regions. Particularly extensive was the new data related to all aspects of the island of South Georgia. Among the results of the investigations was also the discovery of the natural boundary of Antarctica, the Antarctic Convergence.
