Harms, Craig A., et al. “Oil and Sea Turtles.” National Oceanic and Atmospheric Administration. In general, oil spills can affect animals and plants in two ways: from the oil itself and from the response or cleanup operations. 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. 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. 2 Oil Spill Effects on Fisheries. Other factors include what kind of exposure and how much exposure there was. 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. Thus, the oxygen withholding capacity and the percentage of oxygen in water decreases. "Slightly Weathered Exxon Valdez Oil Persists in Gulf of Alaska Beach Sediments after 16 Years." Wildlife recovery, cleaning, and rehabilitation is often an 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 impact of oil spills can also ruin the infrastructure and economy of a particular area with the long-term effects being felt for decades. 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. 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. The impacts of an oil spill on fisheries and mariculture activities can be categorised as direct or indirect. These experts are trained on how to clean oil from animals, rehabilitate them, and return them to the environment. 1. 216-223., doi:10.1016/j.marpolbul.2018.07.003, King, M. D., et al.

These toxic compounds can cause severe health problems like heart damage, stunted growth, immune system effects, and even death. The overall cost and challenge of cleaning up an oil spill is enormous.

AFSC Quarterly Research Reports. Oil-drenched seabirds have become the prevailing image of the effects of oil spills, with the chemicals released by oil spills having the ability to disrupt their bodily functions to such an extent that biologist Sylvia Gaust argued that killing oil-soaked birds would be kinder than cleaning them. The BP oil spill began when the Deepwater Horizon rig suffered an explosion on April 20, 2010. 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. The overall cost and challenge of cleaning up an oil spill is enormous. Shorelines are typically teeming with species that flourish on the water's surface, including birds, sea otters, fish, and invertebrates. 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.. In its first month, BP spilled 30 million gallons of oil into the Gulf, three times the Exxon Valdez oil spill. When oil eventually stops floating on the … The Deepwater Horizon oil spill is recognized as the worst oil spill in U.S. history.

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. People who clean up the spill are more at risk. Every time an oil spill occurs, the public looses faith in the oil companies' ability to control this dangerous but needed product. Understanding both types of impacts can help spill responders minimize overall impacts to ecological communities and help them to recover much more quickly. Direct impacts can include contamination of the boats and gear used in catching or cultivating marine species. The effect of oil pollution is disastrous, especially on the aquatic flora and fauna. Oil Spills Affect Fish. An oil spill can have a major impact on the economy in coastal areas. Frontiers in Veterinary Science, vol. Even a small amount of oil can be deadly to a bird. By coating feathers, oil not only makes flying impossible but also destroys birds' natural waterproofing and insulation, leaving them vulnerable to hypothermia or overheating. As birds frantically preen their feathers to restore their natural protections, they often swallow oil, which can severely damage their internal organs and lead to death. The best estimate of the Exxon Valdez oil spill is that it killed 250,000 seabirds.. 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). Both surfa… If the spill is severe it may take the land years to recover, during which time it … Aquatic beings cannot thrive in toxic environment and that makes oil pollution a disservice to them.

You may have also heard of tarballs, or globby pieces of oil that are left behind after a spill. 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..
