Greene Peninsula
Greene Peninsula is a mountainous peninsula within Cumberland East Bay, separating Moraine Fjord to the west from the main arm of Cumberland East Bay, on the north coast of South Georgia Island. The entire area was charted by the Swedish Antarctic Expedition (SAE), 1901–04, under Otto Nordenskjöld. The peninsula was named by the UK Antarctic Place-Names Committee (UK-APC) in 1979 after Stanley Wilson Greene, a British bryologist who worked in South Georgia. Geography Many features in and around Greene Peninsula have been charted and individually named. Many names in the area were given by the Falkland Islands Dependencies Survey (FIDS) in 1951 following a sketch survey, mostly derived from names of chemicals used to prepare biological material collected there by FIDS personnel. Unless otherwise noted, this applies to features described further in this article. Shoreline and inland Dartmouth Point marks the northernmost end of Greene Peninsula. It was charted by the Swedish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Balsam
Balsam is the resinous exudate (or sap) which forms on certain kinds of trees and shrubs. Balsam (from Latin balsamum "gum of the balsam tree", ultimately from Semitic, Aramaic ''busma'', Arabic ''balsam'' and Hebrew ''basam'', "spice", "perfume") owes its name to the biblical Balm of Gilead. Chemistry Balsam is a solution of plant-specific resins in plant-specific solvents (essential oils). Such resins can include resin acids, esters, or alcohols. The exudate is a mobile to highly viscous liquid and often contains crystallized resin particles. Over time and as a result of other influences the exudate loses its liquidizing components or gets chemically converted into a solid material (i.e. by autoxidation). Some authors require balsams to contain benzoic or cinnamic acid or their esters. Plant resins are sometimes classified according to other plant constituents in the mixture, for example as: * pure resins (guaiac, hashish), * gum-resins (containing gums/polysaccharides) ...

British Admiralty
The Admiralty was a department of the Government of the United Kingdom responsible for the command of the Royal Navy until 1964, historically under its titular head, the Lord High Admiral – one of the Great Officers of State. For much of its history, from the early 18th century until its abolition, the role of the Lord High Admiral was almost invariably put "in commission" and exercised by the Lords Commissioner of the Admiralty, who sat on the governing Board of Admiralty, rather than by a single person. The Admiralty was replaced by the Admiralty Board in 1964, as part of the reforms that created the Ministry of Defence and its Navy Department (later Navy Command). Before the Acts of Union 1707, the Office of the Admiralty and Marine Affairs administered the Royal Navy of the Kingdom of England, which merged with the Royal Scots Navy and the absorbed the responsibilities of the Lord High Admiral of the Kingdom of Scotland with the unification of the Kingdom of Great ...

Eosin
Eosin is the name of several fluorescent acidic compounds which bind to and form salts with basic, or eosinophilic, compounds like proteins containing amino acid residues such as arginine and lysine, and stains them dark red or pink as a result of the actions of bromine on eosin. In addition to staining proteins in the cytoplasm, it can be used to stain collagen and muscle fibers for examination under the microscope. Structures, that stain readily with eosin, are termed eosinophilic. In the field of histology, Eosin Y is the form of eosin used most often as a histologic stain. Etymology Eosin was named by its inventor Heinrich Caro after the nickname (Eos) of a childhood friend, Anna Peters. Variants There are actually two very closely related compounds commonly referred to as eosin. Most often used is in histology is Eosin Y (also known as eosin Y ws, eosin yellowish, Acid Red 87, C.I. 45380, bromoeosine, bromofluoresceic acid, D&C Red No. 22); it has a very slightly yellowi ...

South Georgia Pintail
The South Georgia pintail (''Anas georgica georgica''), also misleadingly known as the South Georgian teal, is the nominate subspecies of the yellow-billed pintail (''Anas georgica''), a duck in the dabbling duck subfamily Anatinae. It is endemic to the large (3,756 km2) subantarctic island of South Georgia and its accompanying archipelago, and is a vagrant to the South Sandwich Islands. It was among the birds noted by James Cook in January 1775, on the occasion of the first recorded landing on South Georgia, and was formerly considered a full species. Taxonomy The duck has long been recognised as a distinct taxon, with its affinities previously considered to be with the teals. Robert Cushman Murphy was the first to demonstrate that it is a pintail, its closest relatives the yellow-billed pintails of South America (now split as the Chilean pintail ''A. g. spinicauda'' and the extinct Niceforo's pintail ''A. g. niceforoi''),Murphy (1916). though he retained it as a full ...

Valley
A valley is an elongated low area often running between Hill, hills or Mountain, mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacier, glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glaciation, glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In karst, areas of limestone bedrock, dry valleys may also result from drainage now taking place cave, underground rather than at the surface. Rift valleys arise principally from tectonics, earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms th ...

Tussock (grass)
Tussock grasses or bunch grasses are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season. Tussock grasses are often found as forage in pastures and ornamental grasses in gardens. Many species have long roots that may reach or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption. Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts. The plants provide habitat and food for insects (including Lepidoptera), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza. The leaves supply material, such as for basket weaving, for indigenous peoples and contemporary artists. Tussock and bunch grasses occur in almost any habitat ...

Sudan I
Sudan I (also commonly known as CI Solvent Yellow 14 and Solvent Orange R), is an organic compound, typically classified as an azo dye. It is an intensely orange-red solid that is added to colourise waxes, oils, petrol, solvents, and polishes. Sudan I has also been adopted for colouring various foodstuffs, especially curry powder and chili powder, although the use of Sudan I in foods is now banned in many countries, because Sudan I, Sudan III, and Sudan IV have been classified as category 3 carcinogens (not classifiable as to its carcinogenicity to humans) by the International Agency for Research on Cancer. Sudan I is still used in some orange-coloured smoke formulations and as a colouring for cotton refuse used in chemistry experiments. Application The Sudan dyes are a group of azo compounds which have been used to color hydrocarbon solvents, oils, fats, waxes, shoes, and floor polishes. As recently as 1974, about of Sudan I, of Sudan II, of Sudan III, and of Sudan IV were prod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 ...

Bryology
Bryology (from Greek , a moss, a liverwort) is the branch of botany concerned with the scientific study of bryophytes (mosses, liverworts, and hornworts). Bryologists are people who have an active interest in observing, recording, classifying or researching bryophytes. The field is often studied along with lichenology due to the similar appearance and ecological niche of the two organisms, even though bryophytes and lichens are not classified in the same kingdom. History Bryophytes were first studied in detail in the 18th century. The German botanist Johann Jacob Dillenius (1687–1747) was a professor at Oxford and in 1717 produced the work "Reproduction of the ferns and mosses." The beginning of bryology really belongs to the work of Johannes Hedwig, who clarified the reproductive system of mosses (1792, ''Fundamentum historiae naturalist muscorum'') and arranged a taxonomy. Research Areas of research include bryophyte taxonomy, bryophytes as bioindicators, DNA sequencing, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
