Oil spill volume is a limited measure of damage or impact. Smaller spills have already proven to have a great impact on ecosystems, such as the "Exxon Valdez" oil spill because of the remoteness of the site or the difficulty of an emergency environmental response. Since 2004, between 300 and 700 barrels of oil per day have been leaking from the site of an oil-production platform 12 miles off the Louisiana coast which sank in the aftermath of Hurricane Ivan.
