The Deepwater Horizon oil spill, ocean acidification, and the decline of fish stocks are just three of the topics that renowned ocean scientist, Dr. Jeremy Jackson discusses in this talk, recorded on World Ocean Day in 2010. Jackson is the former director of the Center for Marine Biodiversity and Conservation and a professor of oceanography at Scripps Institution of Oceanography. He calls this lecture, "Brave New Ocean," and it was the first in the Changing Tides series of presentations. The series was made possible with generous support from the National Science Foundation.
