Marine Protected Areas Of Canada
Marine Protected Areas (MPAs) (french: zones de protection marine) are zones within Canadian waters where the marine environment enjoys a high level of environmental protection. Marine Protected Areas are governed by the ''Oceans Act'' of 1996 and administered by Fisheries and Oceans Canada. Scope of protection Designation as a Marine Protected Area does not automatically prohibit fishing and other activities. Activities within these areas are assessed on a case-by-case basis and will be allowed if they are consistent with the conservation objectives of the specific area. On 25 April 2019, new standards were adopted for marine protected areas that prohibit four industrial activities: oil and gas activities, mining, dumping, and bottom trawling. These standards do not retroactively void existing oil and gas licenses, or void previously approved bottom trawling activities. Instead, the department will assess each issue of these now prohibited activities on a case-by-case basis to e ...

Submarine Canyon
A submarine canyon is a steep-sided valley cut into the seabed of the continental slope, sometimes extending well onto the continental shelf, having nearly vertical walls, and occasionally having canyon wall heights of up to 5 km, from canyon floor to canyon rim, as with the Great Bahama Canyon. Just as above-sea-level canyons serve as channels for the flow of water across land, submarine canyons serve as channels for the flow of turbidity currents across the seafloor. Turbidity currents are flows of dense, sediment laden waters that are supplied by rivers, or generated on the seabed by storms, submarine landslides, earthquakes, and other soil disturbances. Turbidity currents travel down slope at great speed (as much as 70 km/h), eroding the continental slope and finally depositing sediment onto the abyssal plain, where the particles settle out.Continental Margin Sedimentation: From Sediment Transport to Sequence Stratigraphy (Special Publication 37 of the IAS) Ma ...

Scotian Shelf
The Scotian Shelf is a geological formation, part of the Continental shelf, located southwest of Nova Scotia, Canada. It covers an area of , is long and ranges in width from . It has an average depth of . The Scotian Shelf contains the ecologically important Scotian Shelf Large Marine Ecosystem (LME) and the Scotian Shelf Waters (SSW). The northeastern boundary is defined by the Laurentian Channel, where it drops off to . Further south is the continental slope, which sharply drops off to a depth of more than . The southwestern boundary ends at the Northeast Channel, including the Gulf of Maine. The Scotian Shelf is characterized by shallow, offshore banks under the ocean surface, with deep basins and troughs between that vary in depth from . These culminate at Sable Island. A southwesterly ocean current, (occasionally containing runoff from the Gulf of St Lawrence) flows over the inner shelf. The water flow over the banks is weaker and tends have greater variation.

The Gully (Atlantic)
The Gully is a large underwater canyon in the Atlantic Ocean near the edge of the eastern continental shelf of North America. It is located east of Nova Scotia near Sable Island. The Gully is over 65 km long and 16 km wide and reaches depths of over 1 km. It is home to a resident population of northern bottlenose whales, purple sunstarfish and deep-sea coral. Other species of whales, dolphins, fish, squid and shrimp also live there. In 2004, Canada designated The Gully a Marine Protected Area.

Juan De Fuca Ridge
The Juan de Fuca Ridge is a mid-ocean spreading center and divergent plate boundary located off the coast of the Pacific Northwest region of North America. The ridge separates the Pacific Plate to the west and the Juan de Fuca Plate to the east. It runs generally northward, with a length of approximately . The ridge is a section of what remains from the larger Pacific-Farallon Ridge which used to be the primary spreading center of this region, driving the Farallon Plate underneath the North American Plate through the process of plate tectonics. Today, the Juan de Fuca Ridge pushes the Juan de Fuca Plate underneath the North American plate, forming the Cascadia Subduction Zone. Discovery The first indications of a submarine ridge off the coast of the Pacific Northwest was discovered by the , a United States Navy sloop under the command of George Belknap, in 1874. Surveying a route for an undersea cable between the United States and Japan, the USS ''Tuscarora'' discovered a sub ...

Hydrothermal Vent
A hydrothermal vent is a fissure on the seabed from which geothermally heated water discharges. They are commonly found near volcanically active places, areas where tectonic plates are moving apart at mid-ocean ridges, ocean basins, and hotspots. Hydrothermal deposits are rocks and mineral ore deposits formed by the action of hydrothermal vents. Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Under the sea, they may form features called black smokers or white smokers. Relative to the majority of the deep sea, the areas around hydrothermal vents are biologically more productive, often hosting complex communities fueled by the chemicals dissolved in the vent fluids. Chemosynthetic bacteria and Archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, limpets and shrimp. Active hydrothermal vents are thought to exist on Jupiter's moon Europa an ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pacific Marine Ecozone (CEC)
The Pacific Marine Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is a Canadian and American marine ecozone extending to the international waters of the Pacific Ocean from the coasts of Alaska, British Columbia, Washington and Oregon. The islands within the Canadian portion are part of the adjacent Pacific Maritime ecozone. Famous for its tourism and an important shipping channel for Canada, the zone is subject to intense human activity which has damaged ecosystems. Primary effects include overfishing, pollution and even direct habitat destruction. The large and increasing population in nearby coastal areas, including the major centres of Vancouver and Seattle, exerts significant strain on the natural habitats within this ecozone. Geography The large rivers flowing from the Rocky Mountains are a source of nutrients for this ecologically diverse region. They enter the shallow waters over the continental shelf, which underlays the entire ecozone and repr ...

Endeavour Hydrothermal Vents
The Endeavour Hydrothermal Vents (also known as the Main Endeavour Field, MEF, or EHV) are a group of hydrothermal vents in the north-eastern Pacific Ocean, located southwest of Vancouver Island, British Columbia, Canada. The vent field lies below sea level on the northern Endeavour segment of the Juan de Fuca Ridge. In 1982, dredged sulfide samples were recovered from the area covered in small tube worms and prompted a return to the vent field in August 1984, where the active vent field was confirmed by HOV ''Alvin'' on leg 10 of cruise AII-112. The temperatures within the Endeavour Hydrothermal Vent fields differs at the various depths despite some vents being just metres apart. This also has an effect on the different microorganisms and invertebrates that live within the region. In order to best grasp the scale of the EHV region, autonomous vehicles have been deployed to survey the areas and cable systems have been put in place so that that better management practices can ...

Lobster
Lobsters are a family (biology), family (Nephropidae, Synonym (taxonomy), synonym Homaridae) of marine crustaceans. They have long bodies with muscular tails and live in crevices or burrows on the sea floor. Three of their five pairs of legs have claws, including the first pair, which are usually much larger than the others. Highly prized as seafood, lobsters are economically important and are often one of the most profitable commodities in coastal areas they populate. Commercially important species include two species of ''Homarus'' from the northern Atlantic Ocean and scampi (which look more like a shrimp, or a "mini lobster")—the Northern Hemisphere genus ''Nephrops'' and the Southern Hemisphere genus ''Metanephrops''. Distinction Although several other groups of crustaceans have the word "lobster" in their names, the unqualified term "lobster" generally refers to the clawed lobsters of the family Nephropidae. Clawed lobsters are not closely related to spiny lobsters o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
