Abstract

The Deepwater Horizon Event was the nation's first spill of national significance and, as such, had significant challenges and complexities over a normal oil spill response. The Marine Mammal and Sea Turtle Group within the Wildlife Branch officially became operational on April 30, 2010, enhancing the normal stranding response network in the northern Gulf to provide response for marine mammals (cetaceans and manatees) and sea turtles. Throughout the response, the group used previously developed National Guidelines for Oiled Marine Mammal Response, drafted in 2005, to direct collection of samples and data for potential criminal and civil litigation, and to direct animal collection and care activities. While having approved protocols to refer to greatly improved response efficiency, significant gaps became apparent in this existing document due to the challenges associated with coordination across such a complex response. Lessons learned from this event will provide information for further modification and updating of this document, leading to better preparedness for future responses.
