Oil spill, leakage of petroleum onto the surface of a large body of water. Over time, oil waste weathers (deteriorates) and disi… Factors such as oil-biodegradation, ocean currents and response measures (dispersants, burning) reduced coastal o … The impact of oil spills can also ruin the infrastructure and economy of a particular area with the long-term effects being felt for decades. 94, 2015, pp. An oil spill could have potentially disastrous effects on land. Oil on the water and the application of temporary fishing and harvesting bans may prevent normal production, or a loss of But many of the long-term effects from the spill cannot be seen with the naked eye. This mousse becomes even more sticky than oil alone, causing it to stick to organisms and materials much more readily. Human and Ecological Risk Assessment: An International Journal, vol. “Oil and Sea Turtles.” National Oceanic and Atmospheric Administration. The overall cost and challenge of cleaning up an oil spill is enormous. The oil spill in Cebu, although locally significant, pales in comparison to major oil spill disasters in human history. Fukuyama, Allan K., et al. 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. Of the 126 workers at the site that day, 11 were killed by the blast. Handbook of Oil Spill Science and Technology (First Edition). Lasting damage to lands and waterways is one major negative consequence when oil finds its way into the environment. Short, Jeff, Stanley Rice, and Mandy Lindeberg. Attempts to remove the oil through preening also causes birds to swallow oil, which causes severe organ damage. The effects of an oil spill will depend on a variety of factors including, the quantity and type of oil spilled, and how it interacts with the marine environment. Following an oil spill, there are specialists and veterinarians to deal with oiled wildlife. Prevailing weather conditions will also influence the oil’s physical characteristics and its behaviour. The more fish larvae … 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. 1. Short, Jeffrey W., et al. 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. Despite massive clean-up efforts following the 1989 Exxon Valdez oil spill, for example, a study conducted by the National Oceanic and Atmospheric Administration (NOAA) found that 26,000 gallons of oil were still trapped in the sand along the Alaska shoreline. Scientists conducting the study determined that residual oil was declining at less than four percent annually. Thus, the oxygen withholding capacity and the percentage of oxygen in water decreases. It was dubbed as the worst oil spill ever in the Philippines. Mousse resembles food for a number of animals and also attracts certain curious birds and marine life. , Has Prince William Sound Recovered From the Spill? “How Does Oil Impact Marine Life?.” National Oceanic and Atmospheric Administration. 41, 2007, pp: 1245-1250, doi:10.1021/es0620033. The lasting effects of the spill mean they must walk much longer distances to get to the periwinkles. No matter their size, oil spills can have long-lasting effects on the environment. The effects of oil pollution are devastating and well documented. Marine Pollution Bulletin, vol. Alaska Fisheries Science Center, NOAA, 2001. 1. "The Exxon Valdez Oil Spill: How Much Oil Remains?" People who clean up the spill are more at risk. When precious crude oil or refined petroleum is lost, it effects the amount of petroleum and gas available for use. Other causes include natural disasters or deliberate acts. In particular, take a look at the following pages: How Toxic Is Oil? For wildlife caught in an oil spill, being exposed to toxic petroleum products often results in lower reproductive rates, organ damage and death. Weeks after the event, and while it was still in progress, the 2010 Deepwater Horizon oil spill was being discussed as a disaster with far reaching consequences sufficient to impact global economies, marketplaces and policies. 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. This is seen in animals in the immediate vicinity of the oil spill and also by animals farther up the food chain. “Understanding Oil Spills And Oil Spill Response.” U.S. Environmental Protection Agency. 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. "Status of intertidal infaunal communities following the Exxon Valdez oil spill in Prince William Sound, Alaska." The effects of oil spills are worse when the site is near coastal communities. Other factors include what kind of exposure and how much exposure there was. Oil spill can be of two different categories – the land spillage and the aquatic spillage – but they all have a negative impact on both the environment and the society in general. In addition, the 1969 oil spill in Santa Barbara, Calif., caused many laws to be placed on the oil companies operating in and around the United States. Oil spills may occur all around us. The effect of oil pollution is disastrous, especially on the aquatic flora and fauna. Preventing oil spills and using environmentally-friendly oil spill cleaners, rather than other toxic products will help a great deal in minimizing the impact of an oil spill. PAH was found up to 8 miles from the wreckage site and was later found to be causing cardiac arrest in fish. AFSC Quarterly Research Reports. It spreads out and is pushed across the water by wind and currents. Much oil spread at 1100-1300m depth, contaminating and affecting deepwater habitats. NOAA: How Oil Harms Animals and Plants in Marine Environments. The general ways to clean up an oil spill are varied and cause their own environmental effects. 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. “Oil Spills.” National Oceanic and Atmospheric Administration. Oil spills have major environmental and economic effects. When a massive amount of oil is spilled into these areas, it harms the health of marine life. For example, oil can sink down through the sand on beaches into sediments, and can work its way down into the muddy bottoms of marshes and tidal flats. In 2010, for example, after the sinking of the Deepwater Horizon oil rig, more than 5,000 … The damage is hard to measure and contain, since it can effect complex ecosystems and spread if introduced to underground water. With much of their ecosystem destroyed, the tribes were forced to rely on government assistance to continue their lives in the area. John Wiley & Sons, Inc.. 2015. The impacts of an oil spill on fisheries and mariculture activities can be categorised as direct or indirect. “Five Years & Counting: Gulf Wildlife in the Aftermath of the Deepwater Horizon Disaster.” National Wildlife Federation. 216-223.,  doi:10.1016/j.marpolbul.2018.07.003, King, M. D., et al. As the name implies, an oil spill refers to any uncontrolled release of crude oil, gasoline, fuels, or other oil by-products into the environment.Oil spills can pollute land, air, or water. Within days of the April 20, 2010 explosion and sinking of the Deepwater Horizon oil rig in the Gulf of Mexico that killed 11 people, underwater cameras revealed the damaged wellhead pipe was leaking oil and gas on the ocean floor about 42 miles off the coast of Louisiana. Since oil spills can occur anywhere in the ocean or near land, the resources needed to repair the situation in a timely manner are generally not located near the site. Wildlife recovery, cleaning, and rehabilitation is often an There were some immediate impacts to the animals of the Gulf of Mexico that could be seen with the naked eye: pelicans black with oil, fish belly-up in brown sludge, smothered turtles washed up on beaches. An oil spill could have potentially disastrous effects on land. This same incident also derailed the plans to build a facility to remove oil from the Arctic National Wildlife Refuge. The damage is hard to measure and contain, since it can effect complex ecosystems and spread if introduced to underground water. People exposed can suffer from liver damage, skin and lung disorders, increased cancer risk, reproductive damage and … The impacts of an oil spill on fisheries and mariculture activities can be categorised as direct or indirect. Damage to stocks as a result of toxic or smothering effects of the oil … Once most of the oil slick is broken down, the bacteria move onto other materials containing hydrocarbons. Exxon Valdez Oil Spill Trustee Council. Discipline: Ecology . Mathewson, Paul D., et al. According to NOAA, detergents kill coral reefs. Since oil spills can occur anywhere in the ocean or near land, the resources needed to repair the situation in a timely manner are generally not located near the site. The Exxon Valdez oil spill killed 2,800 sea otters, 300 harbor seals, and up to 22 killer whales. In the years after the Exxon Valdez spill, scientists noted higher death rates among sea otters and other species affected by the spill and stunted growth or other damage among additional species. Thirty-five years after the disaster, researchers have found that the Prince William Sound ecosystem seems to have finally recovered, and localized effects on sea otters appear to have been resolved. , Oil spills often take a deadly toll on fish, shellfish, and other marine life, particularly if many fish eggs or larvae are exposed to oil. Shrimp and oyster fisheries along the Louisiana coast were among early casualties of the BP Deepwater Horizon oil spill. Similarly, the Exxon Valdez spill destroyed billions of salmon and herring eggs. Fisheries impacted by the Exxon Valdez took over three decades to recover., Long-term damage to species and their habitats and nesting or breeding grounds is one of the most far-reaching environmental effects caused by oil spills. Even species that spend most of their lives at sea, such as various species of sea turtles, must come ashore to nest. Sea turtles can be harmed by oil they encounter in the water or on the beach where they lay their eggs, their eggs can be damaged by oil and fail to develop properly, and newly hatched turtles may be oiled as they scurry toward the ocean across an oily beach., Ultimately, the severity of environmental damage caused by an oil spill depends on many factors, including the amount of oil spilled, type and weight of oil, location of the spill, species of wildlife in the area, timing of breeding cycles and seasonal migrations, and even the weather at sea during and after the oil spill.. 2 Oil Spill Effects on Fisheries. In 1996, Chavis won the award for "best science fiction/fantasy" from the River Valley Writer’s Conference. Copyright 2020 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. The chemical composition of oil mixes with the water and creates a new substance known as "mousse." In its first month, BP spilled 30 million gallons of oil into the Gulf, three times the Exxon Valdez oil spill. The oil spill will likely disturb the Arctic food chain for decades, perhaps forever. The BP oil spill began when the Deepwater Horizon rig suffered an explosion on April 20, 2010. [Ari Labadi/Al Jazeera] Oil spills have negative impacts on the residents of the affected areas. You may have also heard of tarballs, or globby pieces of oil that are left behind after a spill. Valuable fishing areas maybe closed down for any period of time if an oil spill occurs. 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. Status of intertidal infaunal communities following the Exxon Valdez oil spill in Prince William Sound, Alaska, Assessing Risks to Sea Otters and the Exxon Valdez Oil Spill: New Scenarios, Attributable Risk, and Recovery, d13C and d15N in deep-living fishes and shrimps after the Deepwater Horizon oil spill, Gulf of Mexico, Plan for Deepwater Horizon Oil Spill Natural Resource Injury Restoration: An Overview, Crude Oil and Dispersant Cause Acute Clinicopathological Abnormalities in Hatchling Loggerhead Sea Turtles (Caretta Caretta), Catastrophic Spill Event Analysis: High-Volume, Extended-Duration Oil Spill Resulting from Loss of Well Control on the Gulf of Mexico Outer Continental Shelf.
