Narragansett Bay is one of the best-studied estuaries in the world. Rhode Island has been developing regulatory and management actions to reduce nutrient inputs, particularly those of nitrogen, to the waters of Narragansett Bay. This book was developed in response to a symposium addressing this mandate with coastal/estuarine scientists and environmental management agency personnel. The contributors use long-term data sets to discuss the interactions among biological, ecological, chemical, and physical processes, and discuss what is known about nutrient inputs to the bay ecosystem, the impacts related to nutrient inputs, and how the ecosystem might respond to a sudden reduction in these inputs.
