Marine Protected Areas Of Canada
Marine Protected Areas (MPAs) () are zones within Exclusive economic zone of Canada, Canadian waters where the marine environment receives a high level of environmental protection. Marine Protected Areas are governed by the ''Oceans Act (Canada), Oceans Act'' of 1996 and administered by Fisheries and Oceans Canada. The federal government of Canada has committed to protecting 25% of its oceans as Marine Protected Areas by the year 2025, and a further 5% (30% of the ocean area of the Exclusive economic zone, Exclusive Economic Zone) by 2030. Scope of protection 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 ensure they're i ...

Benthic Zone
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from the Ancient Greek word (), meaning "the depths". Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and Fungus, fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here, known as bottom dwellers, generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud. Description Oceans The benthic region of the ocean begins at t ...

Juan De Fuca Ridge
The Juan de Fuca Ridge is a Mid-ocean ridge, mid-ocean spreading center and divergent plate boundary located off the coast of the Pacific Northwest region of North America, named after Juan de Fuca. 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-of-war, sloop under the command of George Belknap, in 1874. Surveying a route for an undersea cable between the United St ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrothermal Vent
Hydrothermal vents are fissures 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. The dispersal of hydrothermal fluids throughout the global ocean at active vent sites creates hydrothermal plumes. 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, which deliver a wide range of elements to the world's oceans, thus contributing to global marine biogeochemistry. 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 fl ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 mineral, 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 DSV Alvin, 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 underwater vehicle, autonomous vehicles have been deployed to survey the areas and cable systems have been pu ...

Lobster
Lobsters are Malacostraca, malacostracans Decapoda, decapod crustaceans of the family (biology), family Nephropidae or its Synonym (taxonomy), synonym Homaridae. 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 the coastal areas they populate. Commercially important species include two species of ''Homarus'' from the northern Atlantic Ocean and Scampi (other), 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 fam ...

Biological Productivity
In ecology, the term productivity refers to the rate of generation of biomass in an ecosystem, usually expressed in units of mass per volume (unit surface) per unit of time, such as grams per square metre per day (g m−2 d−1). The unit of mass can relate to dry matter or to the mass of generated carbon. The productivity of autotrophs, such as plants, is called primary productivity, while the productivity of heterotrophs, such as animals, is called secondary productivity. The productivity of an ecosystem is influenced by a wide range of factors, including nutrient availability, temperature, and water availability. Understanding ecological productivity is vital because it provides insights into how ecosystems function and the extent to which they can support life. Primary production Primary production is the synthesis of organic material from inorganic molecules. Primary production in most ecosystems is dominated by the process of photosynthesis, In which organisms synthesize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chondrus Crispus
''Chondrus crispus''—commonly called Irish moss or carrageenan moss (Irish ''carraigín'', "little rock")—is a species of red algae which grows abundantly along the rocky parts of the Atlantic coasts of Europe and North America. In its fresh condition it is soft and cartilaginous, varying in color from a greenish-yellow, through red, to a dark purple or purplish-brown. The principal constituent is a mucilaginous body, made of the polysaccharide carrageenan, which constitutes 55% of its dry weight. The organism also consists of nearly 10% dry weight protein and about 15% dry weight mineral matter, and is rich in iodine and sulfur. When softened in water it has a sea-like odour. Because of the abundant cell wall polysaccharides, it will form a jelly when boiled, containing from 20 to 100 times its weight of water. Description ''Chondrus crispus'' is a relatively small sea alga, reaching up to a little more than in length. It grows from a discoid holdfast and branches four ...
