Since the pioneering work of Clarke et a1. (1970) it has been known that chlorophyll a (or. more generally. pigments) contained in phytoplankton in near-surface waters produced systematic variations in the color of the ocean which could be observed from aircraft. As a direct result of this work. NASA developed the Coastal Zone Color Scanner (CZCS). which was launched on Nimbus-G (now Nimbus-7) in October 1978. (A short description of the CZCS is provided in Appendix I. ) Shortly before launch. at the IUCRM Colloquium on Passive Radiometry of the Ocean (June 1978). a working group on water color measurements was formed to assess water color remote sensing at that time. A report (Morel and Gordon. 1980) was prepared which summarized the state-of-the-art of the algorithms for atmospheric correction. and phytoplankton pigment and seston retrieval. and which included recommendations concerning the design of next generation sensors. The water color session of the COSPAR/SCOR/IUCRM Symposium 'Oceanography from Space' held in Venice (May 1980. i. e •• in the post-launch period) provided the opportunity for a reassessment of the state-of-the-art after having gained some experience in the analysis of the initial CZCS imagery. Such an assessment is the purpose of this review paper. which will begin with an outline of the basic physics of water color remote sensing and the fundamentals of atmospheric corrections. The present state of the constituent retrieval and atmospheric correction algorithms will then be critically assessed.

The papers contained in this volume were presented orally at the seventh POLYMODEL conference, held at Sunderland Polytechnic in the United King dom in May 1984 and sponsored by Barclays Bank PLC and Imperial Chemical Industries Ltd. The conferences are organised annually by the North East of England Polytechnic's Mathematical Modelling and Computer Simulation Group - POLYMODEL. The Group is a non-profit making organisation based on the mathematics department of the three polytechnics in the region and has membership drawn from those educational institutions and from regional industry. Its objective is to promote research and collaboration in mathematical and computer-based modelling. After a short introductory chapter, the volume may be considered as dividing naturally into four parts. Chapters 2 to 5 constitute the first part on Tides, Storm Surges and Coastal Circulations which deals with the hydrodynamics of coastal seas. Chapters 6 to 11 concern Coastal Engine ering Modelling and discuss such coastal phenomena as beach erosion, sediment transport, and non-linear waves. The third part (Chapters 12 to 16) on Offshore Structures considers sea structures in general and the connections between the structures (hoses, moorings, pipelines) in particular. The last two chapters focus on Offshore Corrosion problems.

Several textbooks and useful compendia on fisheries have been published recently, and others are in preparation. The question then arises: why publish another book on fisheries at this time? My answer is 1) that fishery research and management are such broad subjects that it is difficult, if not impossible, to cover them adequately in one volume; 2) that consequently each author has stressed those aspects of greatest immediate interest to him; and 3) that to the best of my knowl edge no adequate broad treatment of the sociopolitical aspects of fishery management has yet ·appeared, although some good discussions have been published for particular fisheries. This volume grew out of a course that I have taught for the last 12 years at the State University of New Yo·rk at Stony Brook. Originally, the title of the course was Fishery Ecology, which was a matter of surprise to some students when they attended the fi rst few 1 ectures. Despite the sudden recent emergence of ecology as a household word, most people do not understand what the term means. I have found that even some graduate students forget that man is a potent force in the dynamic state of aquatic life. This is not only because he does things that change the environment and so affects living things in it, but also because he has such strange ways of thinking and of managing his affairs.

The background for the Workshop on Cohesive Sediment Dynamics - . !!!!!. Special Reference to Physical Processes in Estuaries is briefly outlined in Chapter I. Here I wish to acknowledge those whose support I consider to be pivotal to this under taking. My deepest appreciation goes to Cynthia Vey, whose organizational skills and dedicated effort made the completion of this volume possible. Thanks are also due to Gail Terry for workshop organization, Jean Branson for word processing and Lillean Pieter for helping with drawings. Finally, I must express my sincere appreciation to Arthur Ezra 9f the National Science Foundation for providing support (through Grant No. CEE-8401185) for the workshop, and to Hsiang Wang for depart mental encouragement. With deepest regret, I must note the untimely death of Ranjan Ariathurai, 39, on June 5, 1985, before this volume could be published. He was a guiding force to many within the small group of researchers in cohesive sediment dynamics, and his professional brilliance and inspirational personal qualities constituted the true spirit . behind the workshop. I trust this volume will serve, albeit in a small way, as a fitting memory to this spirit, and to the remarkable professional contributions Ranjan made during his short career. Professor Ray B.

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.

Physical Nature and Structure of Oceanic Fronts

Skickas inom 10-15 vardagar
During the past several years, research into the frontal divisions of the ocean has been particularly intensive. The significance of this lies not only in the fact that, in the five years from 1976 to 1980, more than 500 papers on this question were published in various journals throughout the world and at least three major international discussions were held (see p. 17). The newness of the discussion of the topic stems from the qualitative reinterpretation of the physical essence of the phenomenon and its role in the ocean, particularly in the processes of mixing and structure formation. While in the past the conventional view of fronts as boundaries between large scale water masses of the ocean only led to the recognition of convenient classi fication limits created by nature itself, there is now a tendency to study oceanic fronts as integral elements of the dynamics of oceanic waters. As we understand it, fronts are being associated more and more with the dynamic and kinematic features which arise when kinetic energy and enstrophy are transmitted through a cascade of scales characterizing various forms of motion of a stratified medium in laterally confined oceanic basins. We are beginning to get a better understanding of the role synoptic-scale oceanic eddies play in the process of frontogenesis in the ocean.

The decision to build a nuclear power plant at Calvert Cliffs on the western shore of the Chesapeake Bay in southern Maryland resulted in a Iandmark legal decision (Calvert Cliffs Coordinating Committee vs Atomic Energy Commission) and began one ofthe mostintensive long-term studies ever carried out in an American estuarine system. In the pages that follow we describe the major results and findings from studies conducted over more than a decade by scientists from The Academy of Natural Seiences of Philadelphia (ANSP). These studies were designed to assess the potential effects that operation ofthe Calvert Cliffs Nuclear Power Plant (CCNPP) might have on the mid-portion of Chesapeake Bay. The approach taken was to study major biotic components of the system over an area and a time period sufficient to allow comparison of conditions between preoperational and operational periods within a sampling locality, and comparisons of conditions at reference sites with those at impact sites afterplant operations began. Elementschosen for detailed study included: species composition and production rates of major primary producers; water chemistry; zooplankton, benthos and finfish abundance and species composition; the abundance and growth rates of commercially important shellfish (clams, oysters and blue crabs); and the colonization sequences of invertebrates on artificial substrates.
Fishery Science and Management
Objectives and Limitations

Skickas inom 10-15 vardagar
This volume is concerned with the role of science in fishery management. While this has traditionally been considered as largely a biological problem with clear biological objectives, close examination suggests that management decisions are largely controlled by political, social and economic considerations, biologically constrained. The biologist now has the task of reducing the uncertainties of the venture rather than determining its priorities or its allocation of benefits. The uncertainties arise in part because of lack of understanding of the ecological systems involved, the limited availability of critical information, and the unpredictability of driving forces. The volume reviews the assumptions and simplifications of fishery models, examines the decision making framework in fishery management, and compares management practices in North America, Japan, and Northern Europe. A compilation of fishery management objectives in international agreements and U.S. laws is included.

Along much of the shoreline of the world, tidal inlets play an important role in nearshore processes, providing links between the coastal oceans and protected embayments. Their study is of particular importance not only for the understanding of fundamental processes in coastal oceanography but also for engineering and the proper management of the delicate equilibrium of our shorelines. This volume, based on the International Symposium on Hydrodynamics and Sediment Dynamics of Tidal Inlets held at Woods Hole, MA, presents the reader with an overview of contemporary research on these important features. The coverage includes: - mathematical modelling, including a review of inlet hydrodynamics, - observations on hydrodynamics, - sedimentology and morphology, - tidal deltas, - processes and policies pertaining to sedimentation, and the - impacts of shore protection and dredging in beaches.

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.

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.

Published by the American Geophysical Union as part of the Coastal and Estuarine Studies, Volume 58.Hypoxia is a condition that occurs when dissolved oxygen falls below the level necessary to sustain most animal life. In U.S. coastal waters, and in the entire western Atlantic, we find the largest hypoxic zone in the northern Gulf of Mexico on the Louisiana/Texas continental shelf. The area affected, which is about the size of the state of New Jersey at its maximal extent, has increased since regular measurements began in 1985. Sediment cores from the hypoxic zone also show that algal production and deposition, as well as oxygen stress, were much lower earlier in the 190Os and that significant increases occurred in the latter half of the twentieth century. We publish this book against the background of such measurements, and to review how the developing and expanding hypoxic zone has affected living resources on this continental shelf.

Published by the American Geophysical Union as part of the Coastal and Estuarine Studies, Volume 61. The effects of increased atmospheric carbon dioxide and related climate change on shallow coral reefs are gaining considerable attention for scientific and economic reasons worldwide. Although increased scientific research has improved our understanding of the response of coral reefs to climate change, we still lack key information that can help guide reef management. Research and monitoring of coral reef ecosystems over the past few decades have documented two major threats related to increasing concentrations of atmospheric CO2: (1) increased sea surface temperatures and (2) increased seawater acidity (lower pH). Higher atmospheric CO2 levels have resulted in rising sea surface temperatures and proven to be an acute threat to corals and other reef-dwelling organisms. Short periods (days) of elevated sea surface temperatures by as little as 1–2°C above the normal maximum temperature has led to more frequent and more widespread episodes of coral bleaching-the expulsion of symbiotic algae. A more chronic consequence of increasing atmospheric CO2 is the lowering of pH of surface waters, which affects the rate at which corals and other reef organisms secrete and build their calcium carbonate skeletons. Average pH of the surface ocean has already decreased by an estimated 0.1 unit since preindustrial times, and will continue to decline in concert with rising atmospheric CO2. These climate-related Stressors combined with other direct anthropogenic assaults, such as overfishing and pollution, weaken reef organisms and increase their susceptibility to disease.
Operational Analysis and Prediction of Ocean Wind Waves

This monograph is an attempt to compile the present state of knowledge on ocean wave analysis and prediction. The emphasis of the monograph is on the development of ocean wave analysis and predic tion procedures and their utility for real-time operations and appli cations. Most of the material in the monograph is derived from journal articles, research reports and recent conference proceedings; some of the basic material is extracted from standard text books on physical oceanography and wind waves. Ocean wave analysis and prediction is becoming an important activity in the meteorological and oceanographic services of many countries. The present status of ocean wave prediction may be compar able to the status of numerical weather prediction of the mid-sixties and early seventies when a number of weather prediction models were developed for research purposes, many of which were later put into operational use by meteorological services of several countries. The increased emphasis on sea-state analysis and prediction has created a need for a ready reference material on various ocean wave analysis and modelling techniques and their utility. The present monograph is aimed at fulfilling this need. The monograph should prove useful to the ocean wave modelling community as well as to marine forecasters, coastal engineers and offshore technologists. The monograph could also be used for a senior undergraduate (or a first year graduate) level course in ocean wave modelling and marine meteorology.

In this paper differences and anomalies in west coast seasonal flow structures have been highlighted. In particular, it was emphasized that flow off Washington has significant differences from that of Oregon; namely, during summer, flow at mid-shelf is more poleward off Washington, and during winter, flow on the inner-shelf is more equatorward off Washington than off Oregon. The former result may be related to the poleward decrease in the longshelf wind stress; the latter result may be related to the presence of the Columbia River plume. Off southern California the near-surface flow over the shelf is more persistently equatorward than that off Washington . Conversely, the flow over the slope in the upper 100 m of the water column is more persistently poleward than that off washington. Also, the undercurrent structure, that is, a subsurface maximum, is maintained at least from summer to early winter off southern California (no data are yet available from spring), but only during summer and early fall off washington. We note that the seasonal cycle of vertical shear in the two locations is similar, although a reversal in sign sometimes occurs off Washington.

Estuaries, bays and contiguous coastal seas are the world's most valuable, and yet most vulnerable marine ecosystems. Fundamental to the protection and management of these important resources is an understand- ing of the physical processes involved which affect the circulation, mixing, and transport of salt, nutrients and sediment. Residual Currents and Long-Term Transport processes appear to have direct control over freshwater inflows, contaminant loadings, dispersion and transport of sediments and nutrients, and causes of declining living resources. This volume provides a comprehensive and up-to-date summary of the research results on these processes in estuaries and bays. Contributions from ten countries include results based on theoretical formulations, analyses of field data, numerical models and case studies.

The application of mesocosms, defined in this report as artificial 3 3 experimental enclosures ranging in size from 1 m to 10m , to address various problems in the marine sciences has been a relatively recent development. The application of the technology was dictated by the realization that many important ocean processes and interactions cannot be fully understood from observations in the natural environment or in smaller enclosures. Such studies involve, for example, determining the interactions between, and energy transfer from, one trophic level to another, the biogeochemical cycling of elements and compounds, etc. These and similar interactions and rate processes cannot normally be established in situations (nature) where the detection and quantification of rate processes are confused by advection and/or the inability to study the same populations over time. In the case of microcosms, mixed populations of primary producers, consumers, and carnivores cannot be maintained, in balance, for a sufficient length of time to determine normal interactions between the various components of these trophic levels. This report, prepared by SCOR Working Group 85, critically examines past applications of mesocosms to ocean research, though there is no attempt to comprehensively review all literature relevant to the subject. Further, the report outlines some important advances emanating from their use and provides recommendations for future applications. It constitutes the first of two reports from the Working Group (see Introduction).

Numerical simulations are in world wide use for the investigation of hydro- and thermodynamic processes in natural waters. In spite of the fact that great achievements have been brought about in this field, numerous questions still remain unanswered, with respect to fundamental formulations as well as to methods of solu- tion. One of the principal objectives of research in our days is the verification of numerical models. The Symposium on "Mathematical Modelling in Estuarine PhysiCS" was held at Hamburg, Aug. 24 - 26, 1978, with the objective of for- mulating the present standing of research work and of the most im- portant problems in this field. Aspects of physical oceanography and of coastal engineering were to be considered. Estuarine phys- ics were a suitable topic as both disciplines have many points in common there. Eighty-five scientists from sixteen countries convened for two and a half days to discuss details with much interest. We wish to thank them as well as the authors for their contributions.Further, we wish to express our gratitude to the German Research Foundation (Deutsche Forschungsgemeinschaft), Bonn-Bad Godesberg, to the Special Research Project 79 "Research in Coastal Waters" (Sonder- forschungsbereich 79 "Wasserforschung im Klistenbereich"), and to the German Hydrographic Institute (Deutsches Hydrographisches Institut), Hamburg, for sponsoring the meeting and for helping with the organization.

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.

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.

When I was asked to organize this symposium on marine producti vity, it made me reflect on what aspects of this subject would be stimulating to a heterogeneous group of laboratory-oriented physiolo gists and biochemists. In recent years there have been several books which discusses the methodology commonly used in primary production studies and described the magnitude of photosynthetic CO reduction 2 in various areas of the world's oceans. I therefore decided to dis pense with these conventional aspects of primary production and invite researchers to speak on a variety of problems relating the abundance and activity of phytoplankton to environmental conditions. The lectures I invited were thus quite diverse in character, but all were related either to factors affecting the rate of photosynthesis or to the fate of reduced carbon as it passes through the microbial food web. In addition to these talks the participants benefited from a number of shorter presentations and poster sessions which dealt with production and cycling of organic carbon in the marine environment.

A wealth of information on osmotic and ionic reaulation in Estuarine and Marine Animals has been accumulated over the past decades. Beyond early studies of whole-animal responses to changes in envi- ronmental salinities, efforts have been made later on to identify, to localize and to characterize the organs and structures responsible for the control of the characteristics of the cell's environmental fluid. When considering the problem of cell volume control in animals facing media of fluctuating salinities, we are indeed dealing with two different categories of mechanisms. A first one is concerned with the control of the osmolality of the intracellular fluid, hence with the processes directly implicated in the maintenance of cell volume and shape. They have been extensively described in several recent review papers. The second category includes the processes controllin~ the charac- teristics of the cell's environmental fluid in order to minimize the amplitude of the osmotic shocks the cells may have to cope with upon acclimation to media of changed salinities. They are localized in particular organs and structures : the so-called "caZt-transporting" epithelia.Up to now, most of the studies on salt-transportino epithe- lia in estuarine and marine animals used the black box approach, so that little or sometimes nothing is still known on the physiological, the biochemical and the biophysical basis of the transporting mecha- nisms as well as on the structure-function relationships.

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.

During the late sixties, the marine scientific community was becoming increasingly aware of the necessity of conducting process-oriented research on specific "problem areas". It was assumed that the results of such detailed analyses would provide an explanatory framework for the descriptive data accumulating from the extensive surveys of the aceans at large that had dominated marine science up to that period. The physical, chemical and biological interaction between the ocean and the Sediments was i dentifi ed as one of the most important i nterdi sei p 1 i nary prob 1 ems at the 1969 meeting of the Intergovernmental Oceanographic Commission. In the same year, a group of scientists from Kiel University - representing the five disciplines: physical, chemical, geological and biological oceanography as well as applied physic- combi ned forces and, in 1970, submitted a comprehens i ve proposa 1 to the German Research Foundati on (DFG: Deutsche Forschungsgemei nschaft) under the tit 1 e "Interact i on Sea-Seabottom" ( "Wechse 1 wi rkung Wasser-Meeresboden"). The professors G. Dietrich, G. Einsele, G. Hempel and E. Seibald were the chief initiators of this project.It addressed two themes: - the relationship between water movement and sediment structure and, - the i nteract i on between the chemi ca 1 regime and the organi sms at the sediment surface.

The last one or two decades have witnessed an increased interest in to pographic Rossby waves, both from a theoretical computational as well as an observational point of view. However, even though long periodic pro cesses were observed in lakes and ocean basins with considerable detail, it appears that interpretation in terms of physical models is not suffi ciently conclusive. The reasons for this lack in understanding may be sought both, in the insufficient spatial resolution or the brevity of the time series of the available data and the inadequacy of the theoretical understanding of long periodic oscillating processes in lakes and ocean bays. Advancement will emerge from intensified studies of both aspects, but it is equally our believe that the understanding of long per'iodic oscillations in lakes is presently likely to profit most from a theore tical-computational study of topographic Rossby waves in enclosed basins. With this tractate we aim to provide the reader with the basic concepts of wave motion in shallow waters at subinertial frequencies. Our ques tions throughout this monogra~h are essentially: How can the solutions to this topographic wave equation in a prescribed idealized domain be construced; what are the physical properties of these solutions; are their features identifiable by observations; how reliable are such in terpretations, etc.
