Recharted in 1933 by DI personnel on the ''Discovery II ''Discovery II'', built in 1971, is the second of three Discovery sternwheel riverboats operated by the Riverboat Discovery company.

Fredriksen Island
Fredriksen Island is an island long and wide, lying 1 km south-east of Powell Island in the South Orkney Islands of Antarctica. It was discovered by Captains Nathaniel Palmer and George Powell in the course of their joint cruise in December 1821. It was named by Norwegian whaling captain Petter Sorlle, who made a running survey of the island in the 1912–13 summer. Important Bird Area The island lies within an Antarctic Specially Protected Area (ASPA 111). It is also part of the Southern Powell Island and adjacent islands Important Bird Area (IBA), identified as such by BirdLife International because it supports significant seabird Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment.

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] |
Petter Sørlle
Petter Sørlle (February 16, 1884 – May 29, 1933) was a Norwegian whaling captain and inventor. Biography Petter Martin Mattias Koch Sørlle was born at Tune (now Sarpsborg) in Østfold, Norway. Both his father and grandfather had been sailors. He was engaged in whaling from Vestfold and later participated in Antarctica whaling near the South Georgia Island and South Orkney Islands. He invented slipways for whaling ships which he patented in 1922. His invention was a device by which the whale could be fully drawn to the ship. The pickup slip was first used in the Antarctic Ocean by the whaling company Globus of Larvik on board the ''FLK Lancing'' during the season 1925–26. Sørlle was the first manager of the United Whalers whaling shore station at Stromness, South Georgia. He carried out surveys and is commemorated by several place names in Antarctic waters. Sørlle Buttress, the Sørlle Rocks and Cape Sørlle are all Antarctic features named after him. List of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Running Survey
A running survey is a rough survey made by a vessel while coasting. Bearings to landmarks are taken at intervals as the vessel sails offshore, and are used to fix features on the coast and further inland. Intervening coastal detail is sketched in. The method was used by James Cook, and subsequently by navigators who sailed under—or were influenced by—him, including George Vancouver, William Bligh and Matthew Flinders Captain Matthew Flinders (16 March 1774 – 19 July 1814) was a British navigator and cartographer who led the first inshore circumnavigation of mainland Australia, then called New Holland. He is also credited as being the first person to u .... References Navigation Surveying James Cook {{Hydrography-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
