This book summarizes three symposia that were convened in the California, Gulf of Maine, and Gulf of Mexico regions to seek new ways to improve the use of science in coastal policymaking. The book recommends actions that could be taken by federal and state agencies and legislatures, local authorities, scientists, universities, the media, nongovernmental organizations, and the public to yield better coastal decisions and policies. It is unique in that it resulted from a partnership among natural scientists, social scientists, and policymakers.
