Eutrophication is a limnological term for the process by which a body of water becomes progressively enriched with minerals and nutrients. Water bodies with very low nutrient levels are termed oligotrophic and those with moderate nutrient levels are termed mesotrophic. Eutrophication may also be referred to as dystrophication or hypertrophication.
Oyster is the common name for a number of different families of salt-water bivalve molluscs that live in marine or brackish habitats. In some species, the valves are highly calcified, and many are somewhat irregular in shape. Many, but not all oysters are in the superfamily Ostreoidea.
Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment. For example, releasing inadequately treated wastewater into natural water bodies can lead to degradation of aquatic ecosystems. In turn, this can lead to public health problems for people living downstream. They may use the same polluted river water for drinking or bathing or irrigation. Water pollution is the leading worldwide cause of death and disease, e.g. due to water-borne diseases.
Puget Sound is a deep inlet of the Pacific Ocean in Washington, extending south from the Strait of Juan de Fuca through Admiralty Inlet. It was explored and named by Captain George Vancouver for his aide, Peter Puget, in 1792.
Marine pollution occurs when harmful effects result from the entry into the ocean of chemicals, particles, industrial, agricultural and residential waste, noise, or the spread of invasive organisms. Eighty percent of marine pollution comes from land. Air pollution is also a contributing factor by carrying off iron, carbonic acid, nitrogen, silicon, sulfur, pesticides or dust particles into the ocean. Land and air pollution have proven to be harmful to marine life and its habitats.
Nonpoint source (NPS) pollution is pollution resulting from many diffuse sources, in direct contrast to point source pollution which results from a single source. Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage, or hydrological modification where tracing pollution back to a single source is difficult.
Ostrea edulis, commonly known as the European flat oyster, is a species of oyster native to Europe. In the British Isles, regional names include Colchester native oyster, mud oyster, or edible oyster. In France, Ostrea edulis are known as huîtres plates except for those that come from the Belon River estuary in Brittany, France, which are known as Belons.
Area sources are sources of pollution which emit a substance or radiation from a specified area.
A fishery is an area with an associated fish or aquatic population which is harvested for its commercial value. Fisheries can be marine (saltwater) or freshwater. They can also be wild or farmed.
Oak Harbor Marina is located in Oak Harbor, Washington, between metropolitan Seattle and the San Juan Islands. The marina was built in 1974 and expanded its guest moorage in 1988 with the installation of the floating breakwater. Income from the marina goes into a city enterprise fund dedicated to the facility's operation and maintenance. It is a 420-boat facility with 217 open and 135 covered permanent slips, 52 guest moorage slips, ample side-tie moorage and 96 dry storage. The boat mix is 40% sailboats and 60% powerboats, ranging in size from 24 feet (7.3 m) up to 50 feet. Twenty-five vessels are liveaboards.
Elliott Bay Marina is a private marina located in Seattle, Washington. It opened in 1991, after 17 years in the planning and permit process. There are 1,200 slips available for moorage. There is a stationary pumpout located on the fuel dock. The facility also has a Porta-Potty dump station.
Port Orchard Marina is a marina located 1 mile away from Bremerton, Washington, across Sinclair Inlet.
Harbour Towne Marina is located on Dania Beach, Florida. This marina invested in a wash-down filtration system and relocated its hull-cleaning area for environmental compliance.
Brewer Cove Haven Marina is a marina located in Barrington, Rhode Island on Narragansett Bay.
Port of Poulsbo is located on Puget Sound, in Liberty Bay, Washington, United States. It includes 7 main docks, which contains 254 permanent slips, 130 guest slips, floatplane dock, fuel dock, sanitation pump-out facilities, shower and restroom facilities, launch ramp and laundry facilities.
Deep River Marina is located on the Connecticut River in Deep River, Connecticut. The marina is on a calm stretch of tidal fresh water off the main channel and is well protected from passing wakes and foul weather. Deep River is well sited, above popular Essex and below Hartford. Its only neighbor is the Essex Valley Railroad, which makes several tourist runs a day along the marina's property line. Within 2 miles (3.2 km) are 5 other marinas and boatyards, with a combined boat population just under 1,000. The boating season runs from mid-April to mid-November. The original boatyard was built in 1955.
Puerto del Rey Marina is a marina in Fajardo, Puerto Rico. With a capacity of over 2,000 boats, it is one of the largest marinas in the Caribbean.
Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients. It is a primary cause of eutrophication of surface waters, in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth. Sources of nutrient pollution include surface runoff from farm fields and pastures, discharges from septic tanks and feedlots, and emissions from combustion. Excess nutrients have been summarized as potentially leading to:
Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and industry, although laws and regulations introduced in the late 20th century have improved water quality in many water bodies. Extensive industrialization and rapid urban growth exacerbated water pollution as a lack of regulation allowed for discharges of sewage, toxic chemicals, nutrients and other pollutants into surface water.
South Korea occupies the southern portion of the Korean peninsula. The total land mass of the country is 98,480 km2 but usable land is only 20% of the total and thus the population is concentrated around the coast. The Korean Peninsula is surrounded by the East, West and South Seas, a coast-line that extends for about 2,413 km. Endowed with an abundance of fisheries resources, Koreans have developed a distinct seafood culture with annual per capita sea food consumption of 48.1 kg in 2005.
