Vancouver Island
Vancouver Island is an island in the northeastern Pacific Ocean and part of the Canadian province of British Columbia. The island is in length, in width at its widest point, and in total area, while are of land. The island is the largest by area and the most populous along the west coasts of the Americas. The southern part of Vancouver Island and some of the nearby Gulf Islands are the only parts of British Columbia or Western Canada to lie south of the 49th parallel. This area has one of the warmest climates in Canada, and since the mid-1990s has been mild enough in a few areas to grow Mediterranean crops such as olives and lemons. The population of Vancouver Island was 864,864 as of 2021. Nearly half of that population (~400,000) live in the metropolitan area of Greater Victoria, the capital city of British Columbia.

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 Sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lakes Of Vancouver Island
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alberni Valley
Alberni Valley is a broad valley located at the head of Alberni Inlet on Vancouver Island in British Columbia, Canada. It is home to Port Alberni, Sproat Lake and other outlining areas. The term is largely used as a synonym for Greater Port Alberni and adjoining communities but is used in a larger regional sense as well. Various local organizations and companies use the term "Alberni Valley" in their name, e.g. the '' Alberni Valley Times'' and ''Alberni Valley News'' newspapers the Alberni Valley Chamber of Commerce and the Alberni Valley Bulldogs minor hockey team. The Canadian pioneer, Joe Drinkwater lived in Alberni Valley during the late nineteenth and early twentieth centuries.

Della Falls
Della Falls is a waterfall located within Strathcona Provincial Park on Vancouver Island in British Columbia, Canada. With a total height of , it ranks as the 16th tallest confirmed waterfall in Canada and the second tallest on Vancouver Island after Kiwi Falls in Schoen Lake Provincial Park. Discovery In 1899, prospector and trapper Joe Drinkwater discovered* Della Falls and named them after his wife. Drinkwater also built a 16 km (10 mi) hiking trail to the falls via Drinkwater Creek. Evidence of his gold mining operation, including an aerial tramway he built, can still be seen near the falls. *Discovered in the European context. The falls were known of by First Nations Peoples long before Drinkwater walked there. Access The only way to reach Della Falls, other than by helicopter, is by crossing the entire Great Central Lake by boat; the only road access to the lake is at the opposite side from Strathcona Park. After the 35 km (21 mi) crossing, there is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sockeye Salmon
The sockeye salmon (''Oncorhynchus nerka''), also called red salmon, kokanee salmon, blueback salmon, or simply sockeye, is an anadromous species of salmon found in the Northern Pacific Ocean and rivers discharging into it. This species is a Pacific salmon that is primarily red in hue during spawning. They can grow up to in length and weigh . Juveniles remain in freshwater until they are ready to migrate to the ocean, over distances of up to . Their diet consists primarily of zooplankton. Sockeye salmon are semelparous, dying after they spawn. Some populations, referred to as kokanee, do not migrate to the ocean and live their entire lives in fresh water. Classification and name origin The sockeye salmon is the third-most common Pacific salmon species, after pink and chum salmon. ''Oncorhynchus'' comes from the Greek ὄγκος (onkos) meaning "barb", and ῥύγχος (rhynchos) meaning "snout". ''Nerka'' is the Russian name for the anadromous form. The name "sockey ...

Steelhead
Steelhead, or occasionally steelhead trout, is the common name of the anadromous form of the coastal rainbow trout or redband trout (O. m. gairdneri). Steelhead are native to cold-water tributaries of the Pacific basin in Northeast Asia and North America. Like other sea-run (anadromous) trout and salmon, steelhead spawn in freshwater, smolts migrate to the ocean to forage for several years and adults return to their natal streams to spawn. Steelhead are iteroparous, although survival is approximately 10–20%. Description The freshwater form of the steelhead is the rainbow trout (''Oncorhynchus mykiss''). The difference between these forms of the species is that steelhead migrate to the ocean and return to freshwater tributaries to spawn, whereas non-anadromous rainbow trout do not leave freshwater. Steelhead are also larger and less colorful than rainbow trout, and can weigh up to and reach in length. They can live up to 11 years and spawn multiple times. The bod ...

Trophic State Index
The Trophic State Index (TSI) is a classification system designed to rate water bodies based on the amount of biological productivity they sustain. Although the term "trophic index" is commonly applied to lakes, any surface water body may be indexed. The TSI of a water body is rated on a scale from zero to one hundred. Under the TSI scale, water bodies may be defined as: * oligotrophic (TSI 0–40, having the least amount of biological productivity, "good" water quality); * mesotrophic (TSI 40–60, having a moderate level of biological productivity, "fair" water quality); or * eutrophic to hypereutrophic (TSI 60–100, having the highest amount of biological productivity, "poor" water quality). The quantities of nitrogen, phosphorus, and other biologically useful nutrients are the primary determinants of a water body's TSI. Nutrients such as nitrogen and phosphorus tend to be limiting resources in standing water bodies, so increased concentrations tend to result in increased ...
