Oil-spill
An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution. The term is usually given to marine oil spills, where oil is released into the ocean or coastal waters, but spills may also occur on land. Oil spills may be due to releases of crude oil from tankers, offshore platforms, drilling rigs and wells, as well as spills of refined petroleum products (such as gasoline, diesel) and their by-products, heavier fuels used by large ships such as bunker fuel, or the spill of any oily refuse or waste oil. Oil spills penetrate into the structure of the plumage of birds and the fur of mammals, reducing its insulating ability, and making them more vulnerable to temperature fluctuations and much less buoyant in the water. Cleanup and recovery from an oil spill is difficult and depends upon many factors, including the type of oil spilled, the temperature of the water (affecting eva ...

Crude Oil
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other Unconventional (oil & gas) reservoir, unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by Continuous distillation#Continuous distillation of crude oil, distillation, into innume ...

Environmental Issues In The Niger Delta
Environmental issues in the Niger Delta are caused by its petroleum industry. The delta covers within wetlands of formed primarily by sediment deposition. Home to 20 million people and 40 different ethnic groups, this floodplain makes up 7.5% of Nigeria's total land mass.Dr. P.C. Nwilo & O. T. Badejo''Impacts of Oil spills along the Nigerian coast''The Association for Environmental Health and Sciences, 2001 It is the largest wetland and maintains the third-largest drainage basin in Africa. The Delta's environment can be broken down into four ecological zones: coastal barrier islands, mangrove swamp forests, freshwater swamps, and lowland rainforests. Fishing and farming are the main sources of livelihoods for majority of her residents. This incredibly well-endowed ecosystem contains one of the highest concentrations of biodiversity on the planet, in addition to supporting abundant flora and fauna, arable terrain that can sustain a wide variety of crops, lumber or agricultural ...

Plumage
Plumage ( "feather") is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morphs. The placement of feathers on a bird is not haphazard, but rather emerge in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month or so l ...

Exxon Valdez Oil Spill
The ''Exxon Valdez'' oil spill occurred in Prince William Sound, Alaska, on March 24, 1989. ''Exxon Valdez'', an oil supertanker owned by Exxon Shipping Company bound for Long Beach, California struck Prince William Sound's Bligh Reef, west of Tatitlek, Alaska at 12:04 a.m. and spilled (or 37,000 tonnes) of crude oil over the next few days. The ''Exxon Valdez'' spill is the second largest in U.S. waters, after the 2010 ''Deepwater Horizon'' oil spill, in terms of volume of oil released. Prince William Sound's remote location, accessible only by helicopter, plane, or boat, made government and industry response efforts difficult and made existing response plans especially hard to implement. The region is a habitat for salmon, sea otters, seals, and seabirds. The oil, extracted from the Prudhoe Bay Oil Field, eventually affected of coastline, of which were heavily or moderately oiled.

Amoco Cadiz
''Amoco Cadiz'' was a VLCC (very large crude carrier) owned by Amoco Transport Corp and transporting crude oil for Shell Oil. Operating under the Liberian flag of convenience, she ran aground on 16 March 1978 on Portsall Rocks, from the coast of Brittany, France. Ultimately she split in three and sank, resulting in the largest oil spill of its kind in history to that date. Oil spill On 16 March 1978 in a southwesterly gale, the ''Amoco Cadiz'' passed Ushant at the western tip of Brittany, headed for Lyme Bay in the United Kingdom. At 9:46 am when the supertanker was north of Ushant and west of Portsall she turned to avoid another ship and her rudder jammed, full over to port. The captain shut down the engine and attempted to make repairs, but they were not successful. Meanwhile, the wind began blowing from the northwest, driving the ship toward the coast. By the time the tugboat ''Pacific'' successfully attached a hawser, it was 2:00 pm and the ''Amoco Cadiz'' had drifted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic Empress
SS ''Atlantic Empress'' was a Greek oil tanker that in 1979 collided with the oil tanker '' Aegean Captain'' in the Caribbean, and eventually sank, having created the fifth largest oil spill on record and the largest ship-based spill having spilled 287,000 metric tonnes of crude oil into the Caribbean Sea. It was built at the '' Odense Staalskibsværft'' shipyard in Odense, Denmark, and launched on 16 February 1974. Ship history The ''Atlantic Empress'' was a large crude oil carrier built at the '' Odense Staalskibsværft'' shipyard in Odense, Denmark, and launched on 16 February 1974.

Bp Oil Spill
The ''Deepwater Horizon'' oil spill (also referred to as the "BP oil spill") was an industrial disaster that began on 20 April 2010 off of the coast of the United States in the Gulf of Mexico on the BP-operated Macondo Prospect, considered to be the largest marine oil spill in the history of the petroleum industry and estimated to be 8 to 31 percent larger in volume than the previous largest, the Ixtoc I oil spill, also in the Gulf of Mexico. The United States federal government estimated the total discharge at . After several failed efforts to contain the flow, the well was declared sealed on 19 September 2010. Reports in early 2012 indicated that the well site was still leaking. The ''Deepwater Horizon'' oil spill is regarded as one of the largest environmental disasters in world history. A massive response ensued to protect beaches, wetlands and estuaries from the spreading oil utilizing skimmer ships, floating booms, controlled burns and of oil dispersant. Due to ...

Sundarbans
Sundarbans (pronounced ) is a mangrove area in the delta formed by the confluence of the Padma, Brahmaputra and Meghna Rivers in the Bay of Bengal. It spans the area from the Baleswar River in Bangladesh's division of Khulna to the Hooghly River in India's state of West Bengal. It comprises closed and open mangrove forests, land used for agricultural purpose, mudflats and barren land, and is intersected by multiple tidal streams and channels. Sundarbans is home to the world's largest area of mangrove forests. Four protected areas in the Sundarbans are enlisted as UNESCO World Heritage Sites, viz. Sundarbans West (Bangladesh), Sundarbans South (Bangladesh), Sundarbans East (Bangladesh) and Sundarbans National Park (India). Despite these protections, the Indian Sundarbans were considered endangered in a 2020 assessment under the IUCN Red List of Ecosystems framework. The Sundarbans mangrove forest covers an area of about , of which forests in Bangladesh's Khulna Division ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
