Prestige oil spill causing great harm to the local fishing industry. The spill is the largest environmental disaster in the history of both Spain and Portugal. The amount of oil spilled was more than the "Exxon Valdez" incident and the toxicity considered higher, because of the higher water temperatures. In 2007 the Southern District of New York dismissed a 2003 lawsuit by the Kingdom of Spain against the American Bureau of Shipping, the international classification society which had certified the "Prestige" as in compliance with rules and laws, because ABS was a "person" per the International Convention on Civil Liability for Oil Pollution
Oil spill volume of the oil can be calculated. Oil spill model systems are used by industry and government to assist in planning and emergency decision making. Of critical importance for the skill of the oil spill model prediction is the adequate description of the wind and current fields. There is a worldwide oil spill modelling (WOSM) program. Tracking the scope of an oil spill may also involve verifying that hydrocarbons collected during an ongoing spill are derived from the active spill or some other source. This can involve sophisticated analytical chemistry focused on finger printing an oil source based on the
