Moraine Fjord
Moraine Fjord is an inlet long with a reef (a terminal moraine) extending across its entrance, forming the west head of Cumberland East Bay, South Georgia. It was charted by the Swedish Antarctic Expedition under Otto Nordenskjöld, 1901–04, who so named it because of the large glacial moraine at its entrance. Discovery Point, formed by glacial moraine, marks the west side of the fjord's entrance. Also surveyed by SAE, it was probably named by Discovery Investigations personnel in the period following their surveys of 1926–31, presumably for their organization or their ships, the ''Discovery'' or ''Discovery II'', which were utilized in the surveys of South Georgia. Carcelles Peak is a peak rising above immediately south of the head of Moraine Fjord. It was surveyed by the South Georgia Survey (SGS) in the period 1951–57, and named by the UK Antarctic Place-Names Committee The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of ...

Terminal Moraine
A terminal moraine, also called end moraine, is a type of moraine that forms at the terminal (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, has been pushed by the front edge of the ice, is driven no further and instead is deposited in an unsorted pile of sediment. Because the glacier acts very much like a conveyor belt, the longer it stays in one place, the greater the amount of material that will be deposited. The moraine is left as the marking point of the terminal extent of the ice. Formation As a glacier moves along its path, the surrounding area is continuously eroding. Loose rock and pieces of bedrock are constantly being picked up and transported with the glacier. Fine sediment and particles are also incorporated into the glacial ice. The accumulation of these rocks and sediment together form what is called glacial till when deposited. Push moraines are formed when a glacier retreats from a previou ...

Cumberland East Bay
Cumberland East Bay is a bay forming the eastern arm of Cumberland Bay, South Georgia. It is entered between Sappho Point on Thatcher Peninsula and Barff Point on Barff Peninsula. It is nearly wide, and extends in a southeast direction. History This feature was first surveyed by the Swedish Antarctic Expedition, 1901–04, who named it "South Bay". It was remapped during 1926–29 by Discovery Investigations personnel and renamed "East Cumberland Bay", which is more descriptive of its geographic position. The shortened form "East Bay" was simultaneously used. Following the South Georgia Survey, 1951–52, the UK Antarctic Place-Names Committee proposed that the name be altered to Cumberland East Bay and that all other names be rejected. This change brings together information about the whole of Cumberland Bay in one place in indexes, and will avoid confusion with East Bay in Prince Olav Harbour, South Georgia. On 22–24 April 1982, during the Falklands War, the British ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Georgia Island
South Georgia ( es, Isla San Pedro) is an island in the South Atlantic Ocean that is part of the British Overseas Territory of South Georgia and the South Sandwich Islands. It lies around east of the Falkland Islands. Stretching in the east–west direction, South Georgia is around long and has a maximum width of . The terrain is mountainous, with the central ridge rising to at Mount Paget. The northern coast is indented with numerous bays and fjords, serving as good harbours. Discovered by Europeans in 1675, South Georgia had no indigenous population due to its harsh climate and remoteness. Captain James Cook in made the first landing, survey and mapping of the island, and on 17 January 1775 he claimed it a British possession, naming it "Isle of Georgia" after King George III. Through its history, it served as a whaling and seal hunting base, with intermittent population scattered in several whaling bases, the most important historically being Grytviken. The main settleme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swedish Antarctic Expedition
The Swedish Antarctic Expedition of 1901–1903 was a scientific expedition led by Otto Nordenskjöld and Carl Anton Larsen. It was the first Swedish endeavour to Antarctica in the Heroic Age of Antarctic Exploration. Background Otto Nordenskjöld, a Swedish geologist and geographer, organized and led a scientific expedition of the Antarctic Peninsula. The expedition's overall command was placed under the Norwegian Carl Anton Larsen, an experienced Antarctic explorer who served as captain of , and who had previously commanded a whaling reconnaissance mission in 1892–1893. Seven other scientists, including archaeologist Johan Gunnar Andersson, botanist Carl Skottsberg, and zoologist Axel Ohlin, along with 16 officers and men joined them on the voyage. On 16 October 1901, the ''Antarctic'' left the Port of Gothenburg. Events Despite its end and the great hardships endured, the expedition would be considered a scientific success, with the parties having explored muc ...

Otto Nordenskjöld
Nils Otto Gustaf Nordenskjöld (6 December 1869 – 2 June 1928) was a Finnish and Swedish geologist, geographer, and polar explorer. Early life Nordenskjöld was born in Hässleby in Småland in eastern Sweden, in a Finland Swedish family that included his maternal uncle, the polar explorer Adolf Erik Nordenskiöld, and cousin Gustaf Nordenskiöld. His father and mother were cousins, but his father's family name was "Nordenskjöld", while his mother's family name was spelled "Nordenskiöld". He studied at Uppsala University, obtaining a doctorate in geology in 1894, and later became a lecturer and then associate professor in the university's geology department. Career Otto Nordenskjöld led mineralogical expeditions to Patagonia in the 1890s, and to Alaska and the Klondike area in 1898. Antarctic Expedition Nordenskjöld led the 1901–1904 Swedish Antarctic Expedition. Their ship ''Antarctic'', commanded by the seasoned Antarctic sailor Carl Anton Larsen, visited Bueno ...

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Provenà ...

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
The RRS ''Discovery'' is a barque-rigged auxiliary steamship built in Dundee, Scotland for Antarctic research. Launched in 1901, she was the last traditional wooden three-masted ship to be built in the United Kingdom. Her first mission was the British National Antarctic Expedition, carrying Robert Falcon Scott and Ernest Shackleton on their first, and highly successful, journey to the Antarctic, known as the ''Discovery'' Expedition. After service as a merchant ship before and during the First World War, ''Discovery'' was taken into the service of the British government in 1923 to carry out scientific research in the Southern Ocean, becoming the first Royal Research Ship. The ship undertook a two-year expedition – the Discovery Investigations – recording valuable information on the oceans, marine life and being the first scientific investigation into whale populations. From 1929 to 1931 ''Discovery'' served as the base for the British Australian and New Zealand Antarctic ... [...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 invo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Summit (topography)
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary ...

South Georgia Survey
The South Georgia Survey was a series of expeditions to survey and map the island of South Georgia, led by Duncan Carse between 1951 and 1957. Although South Georgia had been commercially exploited as a whaling station during the first half of the 20th century, its interior was generally unknown, and maps were largely based on the original survey by James Cook, who first landed on the island in 1775. The South Georgia Survey was intended to make high-quality modern maps covering the entire island, and took place in four austral summer seasons: 1951–52, 1953–54, 1955–56, and 1956–57. The survey was funded by the Royal Geographical Society, the Falkland Islands Dependencies, Odhams Press, and other private supporters. The War Office and Ministry of Supply provided 250 man-days of cold-weather rations, along with a loan of clothing and sledging equipment. Transportation to and from South Georgia was provided on the ships used to supply the whaling stations and ferry whale o ... [...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 Scientific Committee on Antarctic Research, 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 featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
