BP state. The "Deepwater Horizon" oil spill was a major industrial accident on the Gulf of Mexico, which killed 11 people and injured 16 others, leaked about of oil with plus or minus 10% uncertainty, which makes it the largest accidental marine oil spill in the history of the petroleum industry, and cost to the company more than $65 billion of cleanup costs, charges and penalties. On 20 April 2010, the semi-submersible exploratory offshore drilling rig "Deepwater Horizon" located in the Macondo Prospect in the Gulf of Mexico exploded after a blowout. After burning for two days, the rig sank. The
Volume and extent of the Deepwater Horizon oil spill approached the Delta National Wildlife Refuge and Breton National Wildlife Refuge. On 19 May 2010, both NOAA and other scientists monitoring the spill with the European Space Agency Envisat radar satellite stated that oil had reached the Loop Current, which flows clockwise around the Gulf of Mexico towards Florida and then joins the Gulf Stream along the U.S. east coast. On 29 June 2010, NOAA determined that the oil slick was no longer a threat to the loop current and stopped tracking offshore oil predictions that include the loop currents region. The omission is noted prominently on the ongoing nearshore
