Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Surface Layer
The surface layer is the layer of a turbulent fluid most affected by interaction with a solid surface or the surface separating a gas and a liquid where the characteristics of the turbulence depend on distance from the interface. Surface layers are characterized by large normal gradients of tangential velocity and large concentration gradients of any substances (temperature, moisture, sediments et cetera) transported to or from the interface. The term boundary layer is used in meteorology and in physical oceanography. The atmospheric surface layer is the lowest part of the atmospheric boundary layer (typically the bottom 10% where the log wind profile is valid). The ocean has two surface layers: the benthic, found immediately above the sea floor and the marine surface layer, at the air-sea interface. Mathematical formulation A simple model of the surface layer can be derived by first examining the turbulent momentum flux through a surface. Using Reynolds decomposition to express ...

Secchi Disk
The Secchi disk (or Secchi disc), as created in 1865 by Angelo Secchi, is a plain white, circular disk in diameter used to measure water transparency or turbidity in bodies of water. The disc is mounted on a pole or line, and lowered slowly down in the water. The depth at which the disk is no longer visible is taken as a measure of the transparency of the water. This measure is known as the Secchi depth and is related to water turbidity. Since its invention, the disk has also been used in a modified, smaller diameter, black and white design to measure freshwater transparency. Similar disks, with a black-and-yellow pattern, are used as fiducial markers on vehicles in crash tests, crash-test dummies, and other kinetic experiments. History The original Secchi disk was a plain white disk and was used in the Mediterranean Sea. Today, a plain white, diameter Secchi disk remains the standard design used in marine studies. In 1899 George C. Whipple modified the original all-white Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Residence Time Of Lake Water
Lake retention time (also called the residence time of lake water, or the water age or flushing time) is a calculated quantity expressing the mean time that water (or some dissolved substance) spends in a particular lake. At its simplest, this figure is the result of dividing the lake volume by the flow in or out of the lake. It roughly expresses the amount of time taken for a substance introduced into a lake to flow out of it again. The retention time is especially important where pollutants are concerned. Global retention time The global retention time for a lake (the overall mean time that water spends in the lake) is calculated by dividing the lake volume by either the mean rate of inflow of all tributaries, or by the mean rate of outflow (ideally including evaporation and seepage). This metric assumes that water in the lake is well-mixed (rather than stratified), so that any portion of the lake water is much like any other. In reality, larger and deeper lakes are generally n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Survey Of Canada
The Geological Survey of Canada (GSC; french: Commission géologique du Canada (CGC)) is a Canadian federal government agency responsible for performing geological surveys of the country, developing Canada's natural resources and protecting the environment. A branch of the Earth Sciences Sector of Natural Resources Canada, the GSC is the country's oldest scientific agency and was one of its first government organizations. History In September 1841, the Province of Canada legislature passed a resolution that authorized the sum of £1,500 sterling be granted to the government for the estimated expense of performing a geological survey of the province. In 1842, the Geological Survey of Canada was formed to fulfill this request.Christy Vodden (1992)No Stone Unturned: The First 150 years of the Geological Survey of Canada Geological Survey of Canada Web site William Edmond Logan was in Montreal at the time and made it known that he was interested in participating in this survey.

Alexander Murray (geologist)
Alexander Murray, (2 June 1810 – 18 December 1884) was a Scottish geologist. Murray is best known for his career with the Geological Survey of Canada and the Geological Survey of Newfoundland. Biography Early life Alexander Murray was born at Dollerie House, Crieff, Perthshire, Scotland on 2 June 1810. He was educated at the Royal Navy Academy and joined the Royal Navy in 1824. During his career in the navy, Murray was wounded at the Battle of Navarino and received a medal for his actions. Murray became a lieutenant in 1833 and retired from service in 1835. Following his retirement, Murray immigrated to Woodstock, Upper Canada. During the Rebellions of 1837–1838, Murray volunteered for service and served in Lieutenant Andrew Drew's naval brigade, which destroyed the US steamer Caroline. After spending a period farming, Murray and his family returned to England in 1841, and he applied unsuccessfully for re-appointment to the Royal Navy. During his time in Englan ...

Hudson’s Bay Company
The Hudson's Bay Company (HBC; french: Compagnie de la Baie d'Hudson) is a Canadian retail business group. A fur trading business for much of its existence, HBC now owns and operates retail stores in Canada. The company's namesake business division is Hudson's Bay, commonly referred to as The Bay ( in French). After incorporation by English royal charter in 1670, the company functioned as the ''de facto'' government in parts of North America for nearly 200 years until the HBC sold the land it owned (the entire Hudson Bay drainage basin, known as Rupert's Land) to Canada in 1869 as part of the Deed of Surrender, authorized by the Rupert's Land Act 1868. At its peak, the company controlled the fur trade throughout much of the English- and later British-controlled North America. By the mid-19th century, the company evolved into a mercantile business selling a wide variety of products from furs to fine homeware in a small number of sales shops (as opposed to trading posts) acros ...

Lake Trout
The lake trout (''Salvelinus namaycush'') is a freshwater char living mainly in lakes in northern North America. Other names for it include mackinaw, namaycush, lake char (or charr), touladi, togue, and grey trout. In Lake Superior, it can also be variously known as siscowet, paperbelly and lean. The lake trout is prized both as a game fish and as a food fish. Those caught with dark coloration may be called ''mud hens''. Taxonomy It is the only member of the subgenus ''Cristovomer'', which is more derived than the subgenus '' Baione'' (the most basal clade of ''Salvelinus'', containing the brook trout (''S. fontinalis'') and silver trout (''S. agasizii'')) but still basal to the other members of ''Salvelinus''. Range From a zoogeographical perspective, lake trout have a relatively narrow distribution. They are native only to the northern parts of North America, principally Canada, but also Alaska and, to some extent, the northeastern United States. Lake trout have been wide ...

First Nations In Canada
First Nations (french: Premières Nations) is a term used to identify those Indigenous Canadian peoples who are neither Inuit nor Métis. Traditionally, First Nations in Canada were peoples who lived south of the tree line, and mainly south of the Arctic Circle. There are 634 recognized First Nations governments or bands across Canada. Roughly half are located in the provinces of Ontario and British Columbia. Under Charter jurisprudence, First Nations are a "designated group," along with women, visible minorities, and people with physical or mental disabilities. First Nations are not defined as a visible minority by the criteria of Statistics Canada. North American indigenous peoples have cultures spanning thousands of years. Some of their oral traditions accurately describe historical events, such as the Cascadia earthquake of 1700 and the 18th-century Tseax Cone eruption. Written records began with the arrival of European explorers and colonists during the Age of Dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
