100506-N-6070S-230 Gulf of Mexico (May 6, 2010) — Dark clouds of smoke and fire emerge as oil burns during a controlled fire in the Gulf of Mexico. The U.S. Coast Guard working in partnership with BP PLC, local residents, and other federal agencies conducted the “in situ burn” to aid in preventing the spread of oil following the April 20 explosion on Mobile Offshore Drilling Unit Deepwater Horizon.
