Because oil floats on top of water, less light penetrates into the water, limiting the photosynthesis of marine plants and phytoplankton. 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. 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. Part of the oil waste may sink with suspended particulate matter, and the remainder eventually congeals into sticky tar balls. Describe case studies of the ecological effects of oil spills at sea and on land. The underground oil spills are more difficult to catch and yet may be more problematic (oil may reach groundwater more easily and travel with it). Factors such as oil-biodegradation, ocean currents and response measures (dispersants, burning) reduced coastal oiling. Map depicting the effects of the Deepwater Horizon oil spill, caused by the explosion of an oil rig off the coast of Louisiana on April 20, 2010. Oil may strand at the high tide line, leaving black lines or globs of oil on the beach as the tide recedes.

Other factors include what kind of exposure and how much exposure there was. However, efforts for spill containment and recovery are considered to be only moderately effective. Petroleum (crude oil) is a non-renewable natural resource (Chapter 13) used mainly as a source of energy. Following an oil spill, there are specialists and veterinarians to deal with oiled wildlife. 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. Oysters in many areas of the gulf are returning. Thick layers of oil may coat rocks, beaches, or plants. 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. The second major effect of the oil spill is seen on the economy. When precious crude oil or refined petroleum is lost, it effects the amount of petroleum and gas available for use. Oil spilled into the water, having been pushed by winds and currents, often reaches the shore. The environmental impact of the Deepwater Horizon oil spill is still evident a decade later. Apart from these, the oil spill in water may cause by accidental spills, oil discharges, etc. The BP oil slick had spread over 580 square miles in just three days. Every form of pollution including oil spill has its effect on people and environment. Oil spills have major environmental and economic effects. Oil spills usually happen in the ocean, but oil can spill on land as well. The paradoxical effect of the spill is that scientists know more about the Gulf of Mexico, as well as the physics, ecology, and chemistry of oil spills, than they ever would have otherwise. If appropriate authorities fail to act fast, the economic effects of oil spill may become catastrophic. April 20 marks 10 years since the BP oil spill began off the Louisiana coast when the Deepwater Horizon drilling rig exploded. 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. These effects can depend on what kind of oil was spilled and where (on land, in a river, or in the ocean). The oil residue also can disperse almost invisibly in the water or form a thick mousse with the water. The oils spread fast over a short time to cover vast expanses of the water body. A 2017 study estimated that of at least 402,000 sea turtles exposed to oil during the spill, 51 percent were Kemp’s ridleys, the smallest and most critically endangered species.
