The Workshop on High Seas Governance for the 21st Century was held in New York City on 17-19 October 2007. Over 50 leading experts in international marine policy, science, law and economics gathered to explore policy and regulatory options to improve oceans governance beyond areas of national jurisdiction (BANJ), particularly as they relate to the protection and preservation of the marine environment and marine biological diversity. Participants attended in their personal capacity and the Workshop was conducted under Chatham House Rules. Co-chairs of the Workshop were David Freestone, Kristina Gjerde, Rosemary Rayfuse and David VanderZwaag.
