Oil spills can coat the feathers of birds, making flying impossible and removing the natural insulation and waterproofing the feathers provide. The oil may also have an effect on the ability of those birds that survive the oil spill to reproduce. Oil spills can also affect human health. Oil spills often happen because of accidents, when people make mistakes or equipment breaks down.

Valuable fishing areas maybe closed down for any period of time if an oil spill occurs. Oil coats fur of otters and seals, leaving them vulnerable to hypothermia. With all manner of sea life destroyed, the culture could not continue to flourish and became essentially a welfare community with a very poor economy. Damage to stocks as a result of toxic or smothering effects of the oil … However this method causes a large amount of air pollution and can get out of control very easily, spreading the fire to other areas. John Wiley & Sons, Inc.. 2015. "Slightly Weathered Exxon Valdez Oil Persists in Gulf of Alaska Beach Sediments after 16 Years." The overall cost and challenge of cleaning up an oil spill is enormous. These effects can depend on what kind of oil was spilled and where (on land, in a river, or in the ocean). Oil spills also damage nesting grounds, potentially causing serious long-term effects on entire species. The 2010 BP Deepwater Horizon offshore oil spill in the Gulf of Mexico, for example, occurred during prime mating and nesting season for many bird and marine species, and long-term environmental consequences of that spill won't be known for years. Oil spills can disrupt migratory patterns by contaminating areas where migrating birds normally stop. Some of the soluble components and emulsions are poisonous, particularly to small organisms that do not have protective coverings or shells- Fish larvae, single celled algae and many kinds of plankton are vulnerable and these are the basic foundation of the marine food chain. How spilled oil affects near-surface creatures depends on when and where the oil spills—those creatures might or might not even be in the area at the location and time of a spill. 241-250, doi:10.1016/j.marpolbul.2015.02.002. AFSC Quarterly Research Reports. This can make the entire ecosystem uninhabitable for years. The chemical composition of oil mixes with the water and creates a new substance known as "mousse." "Assessing Risks to Sea Otters and the Exxon Valdez Oil Spill: New Scenarios, Attributable Risk, and Recovery." Environmental Science & Technology, vol. The fishing industry can be heavily affected by an oil spill. Oil spills caused by damaged tankers, pipelines, or offshore oil rigs often result in immediate and long-term environmental damage that can last for decades. “Water Marks: Louisiana Coastal Wetlands Planning, Protection and Restoration News.” Coastal Wetlands Planning, Protection and Restoration Act. 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. In its first month, BP spilled 30 million gallons of oil into the Gulf, three times the Exxon Valdez oil spill. [Ari Labadi/Al Jazeera] Quintana-Rizzo, Ester, et al. Oil spills have negative impacts on the residents of the affected areas. Yet small oil spills and leaks, such as a damaged jet ski, leaking motorboat, illegally dumped quarts of motor oil, or runoff from road pollution can be just as deadly to birds and other wildlife. The damage is hard to measure and contain, since it can effect complex ecosystems and spread if introduced to underground water. 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. It placed a moratorium on the building of new oil refineries and also a number of rules regarding the transport of oil. Efforts are under way to keep the oil spill in the Gulf of Mexico from reaching birds, mammals and critical shoreline habitats, but some marine biologists worry about the effects of the oil slick and the use of chemical dispersants on life underwater. 216-223.,  doi:10.1016/j.marpolbul.2018.07.003, King, M. D., et al. Factors such as oil-biodegradation, ocean currents and response measures (dispersants, burning) reduced coastal o … One example of this is with the native Inuit peoples near the Exxon Valdez oil spill in Prince William Sound in Alaska in 1989. U.S. Department of the Interior. 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). Nossiter, A. Alaska Fisheries Science Center, NOAA, 2001. Cleaning an oil spill is very expensive and the costs get spread to government agencies, non-profits and the oil transport company itself. Oil spills frequently kill marine mammals such as whales, dolphins, seals, and sea otters. Oil can clog blowholes of whales and dolphins, making it impossible for them to breathe properly and disrupting their ability to communicate. Ecological impact of oil spills on the aquatic animals depends on the location of the oil spills and also on the sensitivity of the local organisms to oil pollution. Lasting damage to lands and waterways is one major negative consequence when oil finds its way into the environment. Oil spills are harmful to marine birds and mammals as well as fish and shellfish. During and after an oil spill, animals can suffer detrimental effects on their fur and feathers. Oil spill, leakage of petroleum onto the surface of a large body of water.

Shorelines are typically teeming with species that flourish on the water's surface, including birds, sea otters, fish, and invertebrates. Spill’s Effects Underwater. But like the microorganisms, these have long-term effects on the ecosystems. 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). These are among the most notable areas of environmental damage caused by spills: Oil spills coat everything they touch and become unwelcome but long-term parts of every ecosystem they enter. When an oil slick from a large spill reaches a beach, oil coats and clings to every rock and grain of sand. If the oil washes into coastal marshes, mangrove forests, or other wetlands, fibrous plants and grasses absorb oil, which can damage plants and make the area unsuitable as wildlife habitat., When oil eventually stops floating on the water's surface and begins to sink into the marine environment, it can have similar damaging effects on fragile underwater ecosystems, killing or contaminating fish and smaller organisms that are essential links in the global food chain.. The effects of oil spill in the marine ecosystem These components affect living organisms in many ways. 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. You may have also heard of tarballs, or globby pieces of oil that are left behind after a spill. Fish may be the most affected in the case of an oil spill. For people attempting to clean the slick, the oil-water mixture is very hard to dispose of and eventually retains very little value as oil itself. Economic impact The most serious threat of oil spills to fisheries and aquaculture activity is the economic loss arising from business interruption. Among those that gained worldwide attention were the oil leaks due to a ruptured well in the Timor Sea in 2009 and a similar incident in the Gulf of Mexico in 2010.

This means more barrels have to be imported from other countries. When oil eventually stops floating on the … Since most of the oil floats in water, the sunlight absorbing capacity of the water decreases.
