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.

Southern Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

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.

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 400, are commonly found in freshwater habitats. ''Spirogyra'' measures approximately 10 to 100 μm in width and may grow to several centimetres in length. It is often observed as green slimy patches on the ground near ponds and other water bodies having stagnant water. General characteristics ''Spirogyra'' is very common in relatively clear eutrophic water, developing slimy filamentous green masses. In spring ''Spirogyra'' grows under water, but when there is enough sunlight and warmth they produce large amounts of oxygen, adhering as bubbles between the tangled filaments. The filamentous masses come to the surface and become visible as slimy green mats. ''Spirog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limnologist
Limnology ( ; from Greek λίμνη, ''limne'', "lake" and λόγος, ''logos'', "knowledge") is the study of inland aquatic ecosystems. The study of limnology 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.Wetzel, R.G. 2001. Limnology: Lake and River Ecosystems, 3rd ed. Academic Press () 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 under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stephen C
Stephen or Steven is a common English first name. It is particularly significant to Christians, as it belonged to Saint Stephen ( grc-gre, Στέφανος ), 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.

A common variant of the name used in English is Stephan ; related names that have found some c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compañía Argentina De Pesca
Compañía Argentina de Pesca ( en, Argentine Fishing Company) 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 ...

Schooner
A schooner () is a type of sailing vessel defined by its rig: fore-and-aft rigged on all of two or more 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. Differing definitions leave uncertain whether the addition of a fore course would make such a vessel a brigantine. Many schooners are gaff-rigged, but other examples include Bermuda rig and the staysail schooner. The origins of schooner rigged vessels is obscure, but there is good evidence of them from the early 17th century in paintings by Dutch marine artists. The name "schooner" first appeared in eastern North America in the early 1700s. The name may be related to a Scots word meaning to skip over water, or to skip stones. The schooner rig was used in vessels with a wide range of purposes. On a fast hull, good ability to windward was useful for priva ...

Deschampsia Antarctica
''Deschampsia antarctica'', the Antarctic hair grass, is one of two flowering plants native to Antarctica, the other being ''Colobanthus quitensis'' (Antarctic pearlwort). They mainly occur on the South Orkney Islands, the South Shetland Islands, and along the western Antarctic Peninsula. A recent warming trend has increased germination, and thus number of seedlings and plants, also extending their range southward to cover larger areas; reports indicate a twenty-fivefold increase in their number. ''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.

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 clinica ...

David D
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, Davi ...
