Response includes technological assessment of equipment and procedures for cleaning up oil spills, and protocols for the detection, monitoring, containment, and removal of oil spills, and the restoration of affected wildlife and habitat. [4]
Large spills alter ecosystem dynamics leading to algae blooms and a mass die-off of marine life. [10] It is estimated that over 1000 sea otters, along with many birds, died from the Exxon Valdez spill. [11] Oil spill clean up efforts commonly employ multiple methods in tandem.
An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution.The term is usually given to marine oil spills, where oil is released into the ocean or coastal waters, but spills may also occur on land.
To break up oil, roughly 1.8 million gallons of Corexit were dropped from planes and sprayed from boats — far more than previous U.S. oil spills. The manufacturer said it was safer than dish soap.
A large clean-up operation began as soon as the Sea Empress started spilling oil. Initially, efforts were made to clean the oil up mechanically, however poor weather conditions resulted in only 3% of the oil being recovered. [7] Over 445 tons of chemical dispersants were sprayed onto the oil using planes between February 18 and February 22. [9]
An oil spill affecting Singapore has spread beyond a luxury beach resort to a marine reserve and other parts of the island as the authorities intensify cleanup efforts.
Three days after the spill more than 650 workers and 17 boats were cleaning the shoreline, gathering up an oily water mixture from the ocean, and hauling away more than 5,000 cubic yards (3,800 m 3) of oil-contaminated soil, sand and vegetation from the coastal bluff.
Oil dispersant mechanism of action. An oil dispersant is a mixture of emulsifiers and solvents that helps break oil into small droplets following an oil spill.Small droplets are easier to disperse throughout a water volume, and small droplets may be more readily biodegraded by microbes in the water.
