Surface oil spills are easy to identify and will leave visible traces such as oil stains, as well as other characteristic signs such as odors due to the vapors emitted by the spilled oil. Valuable fishing areas maybe closed down for any period of time if an oil spill occurs. On waterlogged sediments such as on mudflats, oil will remain on the mud surface if left undisturbed, and be lifted again on the next tide. Since oil products include a lot of common fuels, it is obvious that oil spills may happen at high rates and in many locations, including residential areas. Thus, the oxygen withholding capacity and the percentage of oxygen in water decreases. When the oil is spilled, the water does not mix with oil thus creating a sheen of oil floating on the water.

Every form of pollution including oil spill has its effect on people and environment. It's considered to be the largest oil spill in U.S. history. The impact of the spill on fish populations is still largely unknown, though the study of specific fish species indicates that there could be long-lasting effects for fish exposed to oil. Aquatic beings cannot thrive in toxic environment and that makes oil pollution a disservice to them. However, efforts for spill containment and recovery are considered to be only moderately effective. Oil spills can potentially cost billions of dollars. Initially, fishermen reported an uptick in fish with skin lesions. The impacts of oil pollution on marine ecosystem can be categorized into long term and short term effects.

The Exxon Valdez Oil Spill which occurred on March 24, 1989 in Prince William Sound, Alaska, is considered the Oceanic oil spills became a major environmental problem in the 1960s, chiefly as a result of intensified petroleum exploration and production on continental shelves and the use of supertankers capable of transporting more than 500,000 metric tons of oil. The oils spread fast over a short time to cover vast expanses of the water body. The fishing industry in the area has seen their catches return to normal levels. Petroleum contaminants, if consumed, pose a significant threat to human health, so when an oi… Marine snow is the phenomena of flakes of falling organic material and biological debris cascading down a water column like snowflakes. If appropriate authorities fail to act fast, the economic effects of oil spill may become catastrophic. Apart from these, the oil spill in water may cause by accidental spills, oil discharges, etc. Factors such as oil-biodegradation, ocean currents and response measures (dispersants, burning) reduced coastal oiling. This paper describes the effects of ship-source oil pollution on fishing and mariculture and provides guidance on response measures and management strategies which may help to reduce the severity of oil spill impacts. Through the use of the clean-up methods just mentioned, oil may look like it is gone but in fact it can persist in the environment for decades.

That spill is considered the most infamous oil spill in U.S. history -- although the 2010 BP leak in the Gulf of Mexico proved to be even worse, surpassing Exxon Valdez in scale. Natural cause: Cruid oil takes a long time to produce as it needs the organic matter of the organisms which are dead. Oil that contains volatile organic compounds partially evaporates, losing between 20 and 40 percent of its mass and becoming denser and more viscous (i.e., more resistant to flow). Since most of the oil floats in water, the sunlight absorbing capacity of the water decreases. Oil spills may occur all around us. Effects on marine life : oil spills have negative impact on the marine animals. When precious crude oil or refined petroleum is lost, it effects the amount of petroleum and gas available for use.

Much oil spread at 1100-1300m depth, contaminating and affecting deepwater habitats. Because oil floats on top of water, less light penetrates into the water, limiting the photosynthesis of marine plants and phytoplankton. Then comes the process of cleaning the oil spill, which requires a lot of financing. Thick layers of oil may coat rocks, beaches, or plants. 1. Scientists noted that the prevailing paths of the Gulf of Mexico's Loop Current and a detached eddy located to the west kept much of the oil, which covered a sizable part of the gulf some three months after the accident, from reaching shore.
