Impact of oil spills on ecosystems
Under normal conditions many of the ecosystems most frequently affected by marine oil spills are accustomed to natural disturbances. For example, shallow coral reefs are some of the most dynamic environments, frequently exposed to the intense forces of typhoons and tsunamis. Depending on the magnitude of the spill and its location, the effects can vary, ranging from minimal to serious ones. For instance, oil spills can have a major impact on the temporary animal and fish loss of habitat. Heavy oils may affect several organism functions like respiration, feeding, and thermo-regulation. While safety is a priority for oil and gas companies, spills do happen and can have potentially devastating effects on surrounding ecosystems. But precisely how do they damage the environment, and what impact could this have on humans? Offshore Technology explores the effects of oil spills. Effects of oil spills on wildlife The Effects of Oil Pollution on Aquatic Ecosystems Offshore and Coastal Waters. The loss of predators has a cascade effect on ecosystems, and offshore, Shallow Inshore Waters. Invertebrates like sea stars and coral play an essential role in ocean Shorelines. Some of the most far-reaching Impact of oil spills on marine organisms Ultimately, the impact of oil on marine organisms depends on the fate of the oil. As previously described, when oil is present in the environment, it is either dispersed in the top layer of the water (littoral zone) or remains on the surface and, consequently, on the coastal areas.
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. Oil coats fur of otters and seals, leaving them vulnerable to hypothermia.

At the same time, the entire ecosystem can change temporarily because of the chemical components and elements of the spilled oil that are toxic to the Understanding both types of impacts can help spill responders minimize overall impacts to ecological communities and help them to recover much more quickly. Oil spills are harmful to marine birds and mammals as well as fish and shellfish. oiled shellfish, birds, and turtle. Following an oil spill, there are specialists and Ecosystem impact. The second level of consequences relates to ecosystem injury and recovery from the oil spill (green boxes

7 Dec 2015 Marine pollution has become a global concern. However, the extension of pollution continues and is made severe by the countries which have oil This statement is not to imply that spilled oil has less of an effect in pelagic marine ecosystems, but rather that marine spills occurring offshore may be less likely Effects of Oil Spills: An oil spill happens when liquid petroleum is released into the interference and it can cause a great deal of damage to marine ecosystems . 6 May 2011 After an oil spill occurs, ecology, human health and economy are major concerns. Specifically, this thesis discusses the impacts of oil spills on vertebrates breeding and foraging in terrestrial ecosystems affected by oil, such as coastal marshes that were heavily oiled following the 2010.
