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. The oil spill, which officials estimate could continue throughout the 21st century, will eventually overtake the 2010 BP Deepwater Horizion disaster as

The spill was much smaller than the nearby 1969 Santa Barbara oil spill on January 28, 1969 in which an oil rig blow-out spilled an estimated of crude oil over a ten-day period. The thick crude oil damaged the coats, skin, beaks, and appendages of hundreds of animals. Workers eventually collected 202 dead birds and 99 dead mammals which included at least 46 sea lions and 12 dolphins.
