MOBILE, Ala. (May 4, 2010) Floating barriers are staged on Dauphin Island in preparation for deployment to areas around the Gulf Coast near Mobile Bay. A growing oil slick approaching the area has prompted government and private sector assets to coordinate recovery efforts in the wake of the Deepwater Horizon oil spill. Deepwater Horizon was an ultra-deepwater oil rig that sank April 22, causing a massive oil spill threatening the U.S. Gulf Coast. (USN) 10Spill0504-N-9643K-008
