Book Description
This book reports on the findings of, and swnmarizes the conclusions from, the Port Hacking Estuary Project, a model-guided, multidisciplinary study of an estuarine ecosystem. The Project began in 1973, at a time when it was thought that environmental problems could be solved readily by assembling a multidisciplinary team of research scientists and having them co-ordinate their research around the construction of an ecosystem model. But a decade has passed and time has not been easy on this approach. The anticipated predictive dynamic models have not been produced and bitter argument has often marred the course of such studies. Yet the need to anticipate the flow of various chemical species (carbon, oxygen, nitrogen, phosphorus, toxicants) through the environment remains: the evidence is everywhere, from fertilization of urban lakes to acid rain. The magnitude of the problem ensures that funds will continue to be made available - although with short-term variations as perceptions swing. It is thus clear that although the difficulties are great, so is the need. It is from this background that we present this book. The Port Hacking Estuary Project involved some 15 - 20 research scientists over a period of 5 years. The goal was to research the flow of carbon into, within, and out of a small unpolluted estuary chosen for convenience rather than for its social significance. The idea was to use the information obtained from these studies to build a predictive dynamic model.

Book Description
This book has its genesis in materials collected in the Hestern Central Atlantic region in preparation for a regional seminar on the Changing Law of the Sea and its Implications for Fisheries in the Hestern Atlantic. The Seminar, which was organised by the Food and Agriculture Organisation of the UN and funded by the Norwegian government, was held in Havana, Cuba, 1980. Most of the materials were gathered by the authors as a result of direct contact with the fisheries authorities of the region, and supplemented where possible by information obtained from public sources for the remaining countries not visited. Twenty seven countries in the region were visited, and the authors were able to obtain materials much of which is not readily accessible except in the individual countries. In writing this book, the authors have become indebted to many people for their advice and assistance. He wish to thank in particular the Food and Agriculture Organisation of the United Nations for permitting use to be made of papers submitted to the Havana seminar, and to the following members of that Organisation: L.

Book Description
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.

Book Description
The present lecture notes cover a first course in th~ most common types of stratified flows encountered in Environ mental Hydraulics. Most of the flows are buoyancy flows, i.e. currents in which gravity acts on small density differences. Part I presents the basic concepts of stagnant, densit- stratified water, and of flowing non-miscible stratified fluids. The similarity to the (presumed) well-known open channel flow, subject to a reduced gravity, is illustrated. Part II treats the miscible density stratified flows. In outlining the governing equations, the strong coupling between the turbulence (the mixing) and the mean flow is emphasized. The presentation and discussions of the basic governing equa tions are followed by illustrative examples. Separate chapters are devoted to Dense Bottom Currents, Free Penetrative Convec tion, Wind-driven Stratified Flow, Horizontal Buoyancy Flow and Vertical jet/plumes. Part III presents some examples of practical problems solved on the basis of knowledge given in the present lecture notes. It is the author's experience that the topics treated in chapter 8 and in the subsequent chapters are especially well suited for self-tuition, followed by a study-circle. ACKNOWLEDGEMENT The author has benefited by the valuable help of his col legues at the Institute of Hydrodynamics and Hydraulic Engin eering, the Technical University of Denmark, especially our librarian Mrs. Kirsten Dj¢rup, our secretary Mrs. Marianne Lewis and our technical draftsman Mrs. Liselotte Norup.

Book Description
Deposit feeders, animals that derive nutrition from organic matter in sedimentary deposits, are dominant among the inhabitants of muds and, therefore, of the benthos of much of the ocean. In this volume the critical research problems pertaining to deposit feeders are identified and promising approaches for dealing with those problems are proposed. Interdisciplinary approaches are of utmost importance in the study of deposit feeders and their sedimentary environment, merging fields as disparate as nutritional physiology and sediment geochemistry. Among the topics presented are advances in theories of foraging and digestion, and new experimental approaches to study the potential foods, feeding behavior and physiology of animals that ingest sediment.

Book Description
This volume represents a collection of pioneering papers introducing immunochemical techniques to the aquatic sciences. It is the product of a workshop entitled "Immunochemical Approaches to Coastal, Estuarine and Oceanographic Questions" held at the University of Southern Maine, Portland, Oct. 5-7, 1986. Funding from many sources made this workshop possible, and is gratefully acknowledged. The reader will note great variability in both the quality and scope of the papers which we have divided 'into four sections: I. Background material on the immune system (borrowed from a recent NIH publication) II. Background material related to aquatic sciences III. Techniques IV. Applications Readers familiar with terminology are directed to start with the original contributions related to aquatic sciences, page 21. Some of the contributions are abstracts only. Others are preliminary, for which we are grateful to the authors for their willingness to share recent sometimes tentative findings with a broader community. Some offer novel and tempting insights, but as they exist, lack adequate standards and controls. Others are thorough and represent major scientific contributions. The promise rests in generating and working with reagents of great specificity enabling orders of magnitude improvements in the sensitivity of our measurements. Authors also address the problems and limitations. We thank the numerous authors and reviewers. In support of every successful endeavor is someone of unusual savvy. For us, this has been David A. Phinney. His leadership, wisdom and wit have been important to the introduction of flow cytometry/sorting and immunochemistry into aquatic research.
