Mitigating the Coastal Ecological Damage of Spilled Oil via Oil Anti-Deposition Strategies
Pages 14

About 250 million gallons of oil is accidentally spilled into the marine environment every year. Worldwide, the annual crude oil spillage to the ocean is estimated to be about 150 million gallons per year from ship maintenance, about 35 million gallons from transportation accidents, about 15 million gallons from offshore
