Chaplin Lake
Chaplin Lake is a salt lake in the south-west corner of the Canadian province of Saskatchewan. The lake is in the Prairie Pothole Region of North America, which extends throughout three Canadian provinces and five U.S. states, and within Palliser's Triangle and the Great Plains ecoregion of Canada. Along the northern shore is the village of Chaplin, Chaplin Nature Centre, and a sodium sulphate mine owned and operated by Saskatchewan Mining and Minerals. The lake is divided into four sections by dykes built by the mining company. The Trans-Canada Highway runs along the northern shore and Highway 58 runs through the middle of the lake in a south to north direction. Chaplin Lake and neighbouring Reed and Old Wives Lakes are situated in a physiographic region called the Chaplin Plain Landscape Area. These salt lakes make up the second largest saline lake in Canada, after the Quill Lakes, and the fourth largest in North America. It is a very important region for migratory and nest ...

Western Hemisphere Shorebird Reserve Network
The Western Hemisphere Shorebird Reserve Network (WHSRN) is a conservation strategy targeting shorebirds in the Americas launched in 1985. Its aim is to protect the nesting, breeding and staging habitats of migratory shorebirds. The first site to be classified was Delaware Bay, which was dedicated in May 1986 as a site of Hemispheric Importance. Sites in the Western Hemisphere Shorebird Reserve Network may also be classified as Important Bird Areas, Ramsar wetlands of international importance, or both. There are three possible classifications for sites in the network. Landscapes are always classified as being of Hemispheric Importance. ;Hemispheric Importance :sites that act as staging, nest A nest is a structure built for certain animals to hold eggs or young. Although nests are most closely associated with birds, members of all classes of vertebrates and some invertebrates construct nests. They may be composed of organic materia ...ing or breeding grounds for at least 500 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bay Of Fundy
The Bay of Fundy (french: Baie de Fundy) is a bay between the Canadian provinces of New Brunswick and Nova Scotia, with a small portion touching the U.S. state of Maine. It is an arm of the Gulf of Maine. Its extremely high tidal range is the highest in the world. The name is likely a corruption of the French word , meaning 'split'. Hydrology Tides The tidal range in the Bay of Fundy is about ; the average tidal range worldwide is only . Some tides are higher than others, depending on the position of the moon, the sun, and atmospheric conditions. Tides are semidiurnal, meaning they have two highs and two lows each day, with about six hours and 13 minutes between each high and low tide. Because of tidal resonance in the funnel-shaped bay, the tides that flow through the channel are very powerful. In one 12-hour tidal cycle, about 100 billion tons (110 billion short tons) of water flows in and out of the bay, which is twice as much as the combined total flow of all the rive ...

Fraser River
The Fraser River is the longest river within British Columbia, Canada, rising at Fraser Pass near Blackrock Mountain in the Rocky Mountains and flowing for , into the Strait of Georgia just south of the City of Vancouver. The river's annual discharge at its mouth is or , and it discharges 20 million tons of sediment into the ocean. Naming The river is named after Simon Fraser, who led an expedition in 1808 on behalf of the North West Company from the site of present-day Prince George almost to the mouth of the river. The river's name in the Halqemeylem (Upriver Halkomelem) language is , often seen archaically as Staulo, and has been adopted by the Halkomelem-speaking peoples of the Lower Mainland as their collective name, . The river's name in the Dakelh language is . The ''Tsilhqot'in'' name for the river, not dissimilar to the ''Dakelh'' name, is , meaning Sturgeon ''()'' River ''()''. Course The Fraser drains a area. Its source is a dripping spring at Fraser Pas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brine Shrimp
''Artemia'' is a genus of aquatic crustaceans also known as brine shrimp. It is the only genus in the family Artemiidae. The first historical record of the existence of ''Artemia'' dates back to the first half of the 10th century AD from Urmia Lake, Iran, with an example called by an Iranian geographer an "aquatic dog," although the first unambiguous record is the report and drawings made by Schlösser in 1757 of animals from Lymington, England. ''Artemia'' populations are found worldwide in inland saltwater lakes, but not in oceans. ''Artemia'' are able to avoid cohabiting with most types of predators, such as fish, by their ability to live in waters of very high salinity (up to 25%). The ability of the ''Artemia'' to produce dormant eggs, known as cysts, has led to extensive use of ''Artemia'' in aquaculture. The cysts may be stored indefinitely and hatched on demand to provide a convenient form of live feed for larval fish and crustaceans. Nauplii of the brine shrimp ''Artemia' ...

Wader
245px, A flock of Dunlins and Red knots">Red_knot.html" ;"title="Dunlins and Red knot">Dunlins and Red knots Waders or shorebirds are birds of the order Charadriiformes commonly found wikt:wade#Etymology 1, wading along shorelines and mudflats in order to foraging, forage for food crawling or burrowing in the mud and sand, usually small arthropods such as aquatic insects or crustaceans. The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons. There are about 210 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Some of the Arctic species, such as the little stint, are amongst the longest distance migrants, spending the non- breeding season in the southern hemisphere. Many of the s ...

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the Program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking.

Semipalmated Sandpiper (9296230249)
The semipalmated sandpiper (''Calidris pusilla'') is a very small shorebird. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific ''pusilla'' is Latin for "very small". It is sometimes separated with other "stints" in ''Erolia,'' but, although these apparently form a monophyletic group, the present species' old genus ''Ereunetes'' had been proposed before ''Erolia''. Description It is a small sandpiper, 13–15 cm (5.1-5.9 in) long and weighing around 20-32 g (0.7-1.1 oz). Wingspan ranges from 13.8-14.6 in (35-37 cm). Adults have black legs and a short, stout, straight dark bill. The body is dark grey-brown on top and white underneath. The head and neck are tinged light grey-brown. This bird can be difficult to distinguish from other similar tiny shorebirds, in particular the western sandpiper; these are known collectively as "peeps" or "stints". Breeding and h ...

Crown Corporations Of Canada
Crown corporations in Canada are government organizations with a mixture of commercial and public-policy objectives.Tupper, Allan. 2006 February 7.Crown Corporation" ''The Canadian Encyclopedia'' (last edited 2021 March 18). Retrieved 2021 May 19. They are directly and wholly owned by the Crown (i.e. the government of Canada or a province). Crown corporations represent a specific form of state-owned enterprise. Each corporation is ultimately accountable to (federal or provincial) Parliament through a relevant minister for the conduct of its affairs. They are established by an Act of Parliament and report to that body via the relevant minister in Cabinet, though they are "shielded from constant government intervention and legislative oversight" and thus "generally enjoy greater freedom from direct political control than government departments." Crown corporations are distinct from "departmental corporations" such as the Canada Revenue Agency. Crown corporations have a long-st ...

Salt Mining
Salt mining extracts natural salt deposits from underground. The mined salt is usually in the form of halite (commonly known as rock salt), and extracted from evaporite formations. History Before the advent of the modern internal combustion engine and earth-moving equipment, mining salt was one of the most expensive and dangerous of operations because of rapid dehydration caused by constant contact with the salt (both in the mine passages and scattered in the air as salt dust) and of other problems caused by accidental excessive sodium intake. Salt is now plentiful, but until the Industrial Revolution, it was difficult to come by, and salt was often mined by slaves or prisoners. Life expectancy for the miners was low. Ancient China was among the earliest civilizations in the world with cultivation and trade in mined salt. They first discovered natural gas when they excavated rock salt. The Chinese writer, poet, and politician Zhang Hua of the Jin dynasty wrote in his book ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
