Deepwater Horizon Oil Spill
On April 20, 2010, an explosion on the Deepwater Horizon Macondo oil well drilling platform started the largest marine oil spill in U.S. history, releasing millions of barrels of oil into the Gulf of Mexico. NOAA was on the scene from the earliest moments of the crisis, bringing more than 20 years of experience protecting and restoring our coasts from oil spills.
As the lead science agency for coastal oil spills, NOAA's Office of Response and Restoration provided mission-critical information to guide the emergency response. Today, NOAA continues its commitment to the Gulf as we work to assess the fish, wildlife, and habitat affected by the spill along the coasts of Louisiana, Mississippi, Texas, Alabama, and Florida.
