Ocean 2.0: Global Marine Ecology in the Anthropocene

This lecture is part of the monthly Castle Lecture Series hosted by the Smithsonian's Grand Challenges Consortia.

Emmett Duffy
Director, Tennenbaum Marine Observatories Network
Office of the Under Secretary for Science
June 18, 2014
Noon – 1:00pm EST

When I was born the ocean was still a mysterious and often frightening wilderness. Few people had yet breathed underwater, sailors traveled hundreds of miles without seeing a sign of humanity, and many scoffed at the idea that the sea could be depleted of fish. Those days are gone. In a short 50 years the human population has doubled to 7 billion, our appetites have grown even faster, and advances in every field of science have uncovered a picture of the ocean's depths formerly unimaginable. That picture is both exhilarating and sobering. It’s now clear that humans are the principal force of nature in the seas as on land, and that the future will require active management of nature on a planetary scale. Effective management in turn urgently requires a new paradigm of science that integrates globally, across disciplines, and that takes a rigorous approach to human behavior and ecology.
