This book is composed of a series of lectures given at the New England Aquarium in early 1980. The intent of these lectures was to summarize the issues of ecology, resource management, and law relating to the Georges Bank. Their underlying theme concerns the controversy of whether or not the bank can support both its present fishery and its oil and gas production. In the sense that interest in oil exploration has since subsided, the book is somewhat outdated. Nevertheless, it presents a very readable overview of one of the world's most productive environments, an environment that provides an excellent example of the economic and ecological problems that can result from misuse of its resources.
