GREEN ISLAND LIGHTHOUSE, PRINCE RUPERT, B
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers, and the gentry, while red was r ...

Prince Rupert
Prince Rupert of the Rhine, Duke of Cumberland, (17 December 1619 (O.S.) / 27 December (N.S.) – 29 November 1682 (O.S.)) was an English army officer, admiral, scientist and colonial governor. He first came to prominence as a Royalist cavalry commander during the English Civil War.). Rupert was the third son of the German Prince Frederick V of the Palatinate and Elizabeth, eldest daughter of King James VI and I of Scotland and England. Prince Rupert had a varied career. He was a soldier as a child, fighting alongside Dutch forces against Habsburg Spain during the Eighty Years' War (1568–1648), and against the Holy Roman Emperor in Germany during the Thirty Years' War (1618–1648). Aged 23, he was appointed commander of the Royalist cavalry during the English Civil War, becoming the archetypal "Cavalier" of the war and ultimately the senior Royalist general. He surrendered after the fall of Bristol and was banished from England. He served under King Louis XIV of Franc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chatham Strait
Chatham Strait, or Shee ya xhaak in the Tlingit language, is a narrow passage of the Alexander Archipelago in the southeastern region of the U.S. state of Alaska. It separates Chichagof Island and Baranof Island to its west from Admiralty Island and Kuiu Island on its east. It is long and extends southward from the junction of Icy Strait and Lynn Canal to the open sea. The strait is deep and 5–16 km (3–10 miles) wide. Naming The meanings of the parts of the name in the Tlingit language for Chatham Strait are as follows: Shee, Baranof Island; Ya, face; Xhaak, Center. The southern part of the strait was named Ensenada del Principe in 1775 by Juan Francisco de la Bodega y Quadra. In 1786 La Perouse gave it the name Tschirikow Bay, and in 1789 the fur trader James Colnett named it Christian Sound. Other early fur traders called it Menzies Strait. It received its present name in 1794 when George Vancouver named it Chatham Strait in honor of William Pitt, 1st Earl of Ch ...

Sponge Reef
Sponge reefs are reefs formed by Hexactinellid sponges, which have a skeleton made of silica, and are often referred to as ''glass sponges''. Such reefs are now very rare, and found only in waters off the coast of British Columbia, Washington (state), Washington and southern Alaska. Recently sponge reefs were identified within the strait of Georgia and Howe Sound, Howe sound close to Vancouver. Although common in the late Jurassic period, reef-building sponges were believed to have gone extinct during or shortly after the Cretaceous period, until the existing reefs were discovered Queen Charlotte Sound / Tōtaranui, Queen Charlotte sound in 1987–1988 – hence these sometimes being dubbed living fossils. The reefs serve an important ecological function as habitat, breeding and nursery areas for fish and invertebrates but are currently threatened by the fishery, offshore oil and gas industries. Attempts are being made to protect these unique ecosystems through fishery closures ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dungeness Crab
The Dungeness crab (''Metacarcinus magister'') is a species of crab inhabiting eelgrass beds and water bottoms along the west coast of North America. It typically grows to across the carapace and is a popular seafood. Its common name comes from Dungeness Spit, United States, which shelters a shallow bay inhabited by the crabs. Description The carapace widths of mature Dungeness crabs may reach 10 inches, or 25.4 centimeters, but are typically 6-7 inches, or approximately 15-18 centimeters. They are a popular delicacy, and are the most commercially important crab in the Pacific Northwest, as well as the western states generally. The annual Dungeness Crab and Seafood Festival is held in Port Angeles, Washington each October. Dungeness crabs have a wide, long, hard shell, which they must periodically moult to grow; this process is called ecdysis. They have five pairs of legs, which are similarly armoured, the foremost pair of which ends in claws the crab uses both as defense and ...

Pandalus Hypsinotus
''Pandalus hypsinotus'' is a crustacean in the Pandalidae family, ordinarily in length, but large females may reach . It can be found in the Bering Sea, from the Aleutian Islands to Puget Sound, and in the Sea of Japan at depths of . This species attains maturity as a male, and in varying proportions as a female, in the second year, and becomes a female during the third year. Subsequent survival into the fourth year is very low. Female shrimps carry eggs from November to April. Called humpback shrimp in North America, there a small directed fishery is found in Prince Rupert. where the humpback is held to be the finest eating shrimp of all six species. Called Toyama shrimp () in Japan, as they are found mainly in Toyama Bay is a bay located on the northern shores of the Hokuriku region of Honshu, Japan on the Sea of Japan.

Pacific North Coast Integrated Management Area
The Pacific North Coast Integrated Management Area (PNCIMA: pronounced pin-SEE-ma) is one of five Large Ocean Management Areas (LOMAs), areas of high ecological, social and economic importance, that have been identified by Fisheries and Oceans Canada (DFO) as priority regions for marine planning as part of Canada’s Oceans Action Plan. After years of work by conservation groups, the fishing sector, tourism outfitters, First Nations, scientists and coastal residents, the Government of Canada finally embarked on the PNCIMA marine planning process in 2010. The goal was to develop a plan to conserve this relatively undeveloped region, while fostering sustainable economies on the coast, which promised to make Canada a world leader in marine conservation. The purpose of the PNCIMA planning process is to ensure a healthy, safe, and prosperous ocean area by engaging all interested parties in the collaborative development and implementation of an integrated management plan. The goals of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salinity
Salinity () is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to ‰). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water. A contour line of constant salinity is called an ''isohaline'', or sometimes ''isohale''. Definitions Salinity in rivers, lakes, and the ocean is conceptually simple, but technically challenging to define and measure precisely. Conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sodium bicarbonate which dissolve into ions ...

Inverness Passage
Inverness (; from the gd, Inbhir Nis , meaning "Mouth of the River Ness"; sco, Innerness) is a city in the Scottish Highlands. It is the administrative centre for The Highland Council and is regarded as the capital of the Highlands. Historically it served as the county town of the county of Inverness-shire. Inverness lies near two important battle sites: the 11th-century battle of Blàr nam Fèinne against Norway which took place on the Aird, and the 18th century Battle of Culloden which took place on Culloden Moor. It is the northernmost city in the United Kingdom and lies within the Great Glen (Gleann Mòr) at its northeastern extremity where the River Ness enters the Beauly Firth. At the latest, a settlement was established by the 6th century with the first royal charter being granted by Dabíd mac Maíl Choluim (King David I) in the 12th century. Inverness and Inverness-shire are closely linked to various influential clans, including Clan Mackintosh, Clan Fraser and Clan ...
