This book represents an outgrowth of an interdisciplinary session held at the Seventh International Estuarine Research Federation Conference held at Virginia Beach, Virginia, OCLober 1983. At that meeting, the participants agreed to contribute to and develop a monograph entitled "Tidal Mixing and Plankton Dynamics" by inviting an expanded group of authors to contribute chapters on this theme. The emphasis would be to review and summarize the considerable body of knowledge that has accumulated over the last decade or so on the fundamental role tidal mixing plays in energetic shallow seas and estuaries in stimulating and controlling biological production. We have attempted to provide a mix of contributions, composed of reviews of the state-of-the-art, reports on current research activi ties, summaries of the design and testing of a new generation of innovative instruments for biological and chemical sampling and sorting, and some imaginative ideas for future experiments on stimulated mixing in continental shelf seas. We encouraged the contributors to present critical and thought provoking assessments of current wisdom specifying the sorts of techniques and observational strategies needed to validate the various hypotheses linking physical structure, mixing and circulation to plankton biomass and production. We hope this volume will appeal to incoming research students and established scholars alike. We certainly have enjoyed working with all the authors in compiling this book. We thank the numerous scientists who have served as reviewers, P. Boisvert for typing the manuscripts and W. Bellows for proofreading.
Tidal Mixing Benefits
Tidal mixing, the churning of coastal waters by tidal currents, plays a vital role in marine productivity. Tidal Mixing Benefits explores how this process stimulates biological activity and nutrient cycling, particularly the resuspension of sediment-bound nutrients, influencing phytoplankton growth, and ultimately supporting coastal ecosystems. The book examines the hydrodynamics of tidal mixing, its impact on nutrient availability (such as nitrogen and phosphorus), and the response of phytoplankton communities, highlighting tidal mixing as a primary driver of marine productivity. Because conventional approaches often underestimate the role of physical processes in regulating biological productivity, the book emphasizes incorporating tidal mixing dynamics into marine ecosystem models for more accurate coastal resource management. The book progresses from establishing a framework for understanding tidal hydrodynamics to detailing the mechanisms by which tidal mixing influences nutrient cycling. It then explores the biological consequences of enhanced nutrient availability, focusing on phytoplankton dynamics and primary production. Case studies from diverse coastal environments illustrate how tidal mixing shapes ecosystem structure and function. The book concludes with a discussion of the implications for coastal management and conservation, advocating for the protection of areas crucial for marine productivity. This unique perspective is valuable for researchers, students, and environmental professionals in oceanography, ecology, and environmental management.
Estuarine Circulation

Estuaries exist along the edge of the oceans and seas, and are char acterized by the dilution of sea water by inflowing fresher waters. The motion and interaction of these two types of water (fresh and salt water) determine the salinity distribution within the estuary and that, in turn, affects the organisms residing there. The purpose of this vol ume is to review the status of our understanding of estuarine circu lation and how the circulation patterns affect living and nonliving resources in estuaries. For many years, the primary paradigm for estuarine circulation was the two-layered net or nontidal gravitational circulation pattern first proposed by Dr. Donald Pritchard in his studies of the James River estuary. During the last decade or so, research has focused on the many variations about this theme and the factors that control the transport processes. Many of these aspects are covered in the initial papers in this volume. Water movement, of course, is of interest be cause it transports marine organisms, sediments, and pollutants. Es tuarine circulation has a significant effect on estuarine food chains, and on the distribution and abundance of organisms, such as the American oyster, that are freely transported by the currents during larval stages. The intent is to bring together many of these topics in a single volume. This volume is dedicated to Dr. Donald W.
