This 2-day workshop is the culmination of a study of the status and future of marine biotechnology. The overall goal of this workshop is to examine what was initially called Opportunities for Marine Biotechnology in the United States, to consider where we are now in this field of Environmental Marine Biotechnology, to envision the field in the future, and to discuss any impediments that might be encountered along the way. Opportunities for Environmental Applications of Marine Biotechnology: Proceedings of the October 5-6, 1999, Workshop addresses the question of where the federal government should invest its limited funds and what future initiatives should be planned.
