Signy Island
Signy Island is a small subantarctic island in the South Orkney Islands of Antarctica. It was named by the Norway, Norwegian whaling, 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 . The island 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.

Southern Atlantic Ocean
The Atlantic Ocean is the second largest of the world's five borders of the oceans, oceanic divisions, with an area of about . It covers approximately 17% of Earth#Surface, Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse colonization of North America, Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an Age of Discovery, age of exploration and colonization of the Americas by European powers, most notably Portuguese Empire, Portugal, Spanish Empire, Sp ...

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] |
Meltwater
Meltwater (or melt water) is water released by the melting of snow or ice, including glaciers, glacial ice, tabular icebergs and ice shelf, ice shelves over oceans. Meltwater is often found during early spring (season), spring when snow packs and cryosphere#Lake ice and river ice, frozen rivers melt with rising temperatures, and in the ablation zone of glaciers where the rate of snow cover is reducing. Meltwater can be produced during volcanic eruptions, in a similar way in which the more dangerous lahars form. It can also be produced by the heat generated by the flow itself. When meltwater pools on the surface rather than flowing, it forms melt ponds. As the weather gets colder meltwater will often re-freeze. Meltwater can also collect or melt under the ice's surface. These pools of water, known as subglacial lakes can form due to geothermal heat and friction. Melt ponds may also form above and below Arctic sea ice, decreasing its albedo and causing the formation of thin underw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spirogyra
''Spirogyra'' (common names include water silk, mermaid's tresses, and blanket weed) is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus. ''Spirogyra'' species, of which there are more than 500, are commonly found in freshwater habitats. ''Spirogyra'' measures approximately 10 to 150 micrometres in width (though not usually more than 60) and may grow to several centimetres in length. Distribution ''Spirogyra'' can be been found on every continent on Earth, including Antarctica. It is freshwater algae, found rivers, ponds, and other such bodies of water. Taxonomy The genus Spirogyra was named by German naturalist Johann Heinrich Friedrich Link in 1820. The lectotype, ''Spirogyra'' ''porticalis'' was designated in 1952 by Paul C. Silvia. Reproduction ''Spirogyra'' can reproduce both sexually and asexually. In vegetative reproduction, fragmentation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limnologist
Limnology ( ; ) is the study of inland aquatic ecosystems. It includes aspects of the biological, chemical, physical, and geological characteristics of fresh and saline, natural and man-made bodies of water. This includes the study of lakes, reservoirs, ponds, rivers, springs, streams, wetlands, and groundwater.) Water systems are often categorized as either running ( lotic) or standing ( lentic). Limnology includes the study of the drainage basin, movement of water through the basin and biogeochemical changes that occur en route. A more recent sub-discipline of limnology, termed landscape limnology, studies, manages, and seeks to conserve these ecosystems using a landscape perspective, by explicitly examining connections between an aquatic ecosystem and its drainage basin. Recently, the need to understand global inland waters as part of the Earth system created a sub-discipline called global limnology. This approach considers processes in inland waters on a global scale, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stephen C
Stephen or Steven is an English first name. It is particularly significant to Christians, as it belonged to Saint Stephen ( ), an early disciple and deacon who, according to the Book of Acts, was stoned to death; he is widely regarded as the first martyr (or " protomartyr") of the Christian Church. The name, in both the forms Stephen and Steven, is often shortened to Steve or Stevie. In English, the female version of the name is Stephanie. Many surnames are derived from the first name, including Stephens, Stevens, Stephenson, and Stevenson, all of which mean "Stephen's (son)". In modern times the name has sometimes been given with intentionally non-standard spelling, such as Stevan or Stevon. A common variant of the name used in English is Stephan ( ); related names that have found some currency or significance in English include Stefan (pronounced or in English), Esteban (often pronounced ), and the Shakespearean Stephano ( ).

Compañía Argentina De Pesca
Compañía Argentina de Pesca () was initiated by the British-Norwegian whaler and Antarctic explorer Carl A. Larsen, and established on 29 February 1904 by three foreign residents of Buenos Aires: the Norwegian consul P. Christophersen, H.H. Schlieper (US national), and E. Tornquist (a Swedish banker). Larsen was the company's Manager, in which capacity he organized the building of Grytviken, the first land-based whaling station in Antarctica put into operation on 24 December 1904. Compañía Argentina de Pesca applied for a British whaling leases at the British Legation in Buenos Aires; the application was filed by the company's president Christophersen and Captain Guillermo Núñez, a technical advisor and shareholder in the company who was also Director of Armaments of the Argentine Navy. The lease was granted by the Governor of the Falkland Islands and Dependencies on 1 January 1906, and subsequently renewed. In 1960 Compañía Argentina de ...

Schooner
A schooner ( ) is a type of sailing ship, sailing vessel defined by its Rig (sailing), rig: fore-and-aft rigged on all of two or more Mast (sailing), masts and, in the case of a two-masted schooner, the foremast generally being shorter than the mainmast. A common variant, the topsail schooner also has a square topsail on the foremast, to which may be added a Topgallant sail, topgallant. Differing definitions leave uncertain whether the addition of a Course (sail), fore course would make such a vessel a brigantine. Many schooners are Gaff rig, gaff-rigged, but other examples include Bermuda rig and the staysail schooner. Etymology The term "schooner" first appeared in eastern North America in the early 1700s. The term may be related to a Scots language, Scots word meaning to skip over water, or to skip stones. History The exact origins of schooner rigged vessels are obscure, but by early 17th century they appear in paintings by Dutch marine artists. The earliest known il ...

Deschampsia Antarctica
''Deschampsia antarctica'', the Antarctic hair grass, is one of two flowering plants native to Antarctica, the other being '' Colobanthus quitensis'' (Antarctic pearlwort). Ecology ''Deschampsia antarctica'' mainly occurs on the South Orkney Islands, the South Shetland Islands, and along the western Antarctic Peninsula. ''Deschampsia antartica'' distribution largely depends on the area's nutrient supply of the soil and its water distribution. ''Deschampsia antarctica'' has been recorded by the Guinness Book of World Records as the southernmost flowering plant. In 1981, a specimen was found on the Antarctic Peninsula's Refuge Islands at a latitude of 68°21′S. Since 2009, both ''D.'' ''antarctica'' and ''C. quitensis'' have been spreading rapidly, which studies suggest has been the result of rising air temperatures and a reduction in the number of fur seals. In Antarctica, the plant can be found forming low clumps in wet, protected habitats. See also * Antarctic flora Refe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microbiologist
A microbiologist (from Greek ) is a scientist who studies microscopic life forms and processes. This includes study of the growth, interactions and characteristics of microscopic organisms such as bacteria, algae, fungi, and some types of parasites and their vectors. Most microbiologists work in offices and/or research facilities, both in private biotechnology companies and in academia. Most microbiologists specialize in a given topic within microbiology such as bacteriology, parasitology, virology, or immunology. Duties Microbiologists generally work in some way to increase scientific knowledge or to utilise that knowledge in a way that improves outcomes in medicine or some industry. For many microbiologists, this work includes planning and conducting experimental research projects in some kind of laboratory setting. Others may have a more administrative role, supervising scientists and evaluating their results. Microbiologists working in the medical field, such as clini ...
