On April 20, 2010, the Deepwater Horizon oil rig exploded, opening up a well that pumped nearly 5 million barrels of oil into the ocean. It was the largest spill in U.S. history. In this presentation given at the Smithsonian's National Museum of Natural History on April 19, 2011, experts discuss oil spill remediation, wildlife rescue, and the health of the Gulf of Mexico and its fisheries one year after the Deepwater Horizon oil spill began:

• Dr. Nancy Knowlton, Smithsonian's National Museum of Natural History: Discussion Modertaor
• Dr. David Hollander, University of South Florida: The fate of the oil and its impact
• Dr. Judilee Marrow, National Zoo: Rescuing Gulf Coast wildlife
• Dr. John Stein, NOAA: Gulf seafood and fisheries
• Dr. James Bonner, Clarkson University: Oil spill clean-up

The panel presentation is part of the  "Changing Tides: A Series of Ocean Discussions" in which top ocean scientists explain current research and how it is helping to change the tide in ocean science and conservation.
