Preface

The zone where land and sea meet is composed of a variety of complex environments. The coastal areas of the world contain a large percentage of its population and are therefore of extreme economic importance. Industrial, residential, and recreational developments, as well as large urban complexes, occupy much of the coastal margin of most highly developed countries. Undoubtedly future expansion in many undeveloped maritime countries will also be concentrated on coastal areas. Accompanying our occupation of coasts in this age of technology is a dependence on coastal environments for transportation, food, water, defense, and recreation. In order to utilize the coastal zone to its capacity, and yet not plunder its resources, we must have extensive knowledge of the complex environments contained along the coasts.

The many environments within the coastal zone include bays, estuaries, deltas, marshes, dunes, and beaches. A tremendously broad range of conditions is represented by these environments. Salinity may range from essentially fresh water in estuaries, such as along the east coast of the United States, to extreme hypersaline lagoons, such as Laguna Madre in Texas. Coastal environments may be in excess of a hundred meters deep (fjords) or may extend several meters above sea level in the form of dunes. Some coastal environments are well protected and are not subjected to high physical energy except for occasional storms, whereas beaches and tidal inlets are continuously modified by waves and currents.

Because of their location near terrestrial sources, coastal environments contain large amounts of nutrients. The combination of this nutrient supply with generally shallow water gives rise to a diverse and large fauna and flora. Coastal areas also serve as the spawning and nursery grounds for many open­ocean organisms. Many species in coastal environments are of great

commercial importance, such as clams, oysters, shrimp, and many varieties of fish. It is certain that we 'need better management of these resources. We also need to develop more and improved methods of cultivating these environments.

All of the above examples point out the need for a fundamental knowledge of modem coastal environments. An almost equally important aspect of coastal environments is their role in the geologic record. In order to properly interpret the relationships and depositional environments among various facies preserved in the rock record it is necessary to have a thorough understanding of modern environments (Law of Uniformitarianism). There is a great deal of economic significance to ancient coastal environments. Water, oil, and gas occur in large quantities in various reservoir sands of beach and dune complexes of ancient barrier island and inner shelf sands. The huge clastic wedge deposits of ancient deltaic environments are also a source of petroleum materials and coal.

All of the above examples indicate various reasons that a comprehensive knowledge of coastal environments is necessary for a geologist, engineer, oceanographer, or coastal manager, or for other persons involved in the coastal zone. This book is designed to provide such a background. Most of the important coastal environments are included. The discussions contain such descriptive aspects as morphology and sediment distribution but also emphasize physical processes and their interactions with the sediments and sediment body morphology. Primary consideration is given to the principles involved and to general considerations but numerous case history examples are included.

Our efforts here represent an unusual attempt to produce a text for student use in that each chapter is authored by a different individual or individuals. The subject matter makes this approach a practical one in that the discussion of each of the coastal environments is presented by a specialist who has considerable experience in the environment being discussed.

Each of the chapters that covers one of the coastal environments can stand alone. As a result, these chapters can be ordered to suit the reader or the instructor. The depth of treatment for each of these chapters shows some variation, in part because of the existing literature. For example, there are many volumes devoted to beaches, estuaries, and deltas in addition to the journal literature. Such coastal environments as dunes and marshes, in contrast, have not received the same coverage in the literature, especially by way of thorough summaries. These environments therefore have been treated in more detail than other environments. The chapters on dunes and marshes are probably the most comprehensive summaries available in the literature.

The last two chapters both involve applications of basic principles to the study of coastal environments or coastal systems. The chapter on sequences, especially Holocene stratigraphic sequences, provides an excellent frame­work for the reader to gain an understanding of Walther's Law as well as coastal systems. Application of computer techniques to coastal sedimenta-

tion has been an important and valuable tool. The discussion of this topic considers various approaches to modeling, including conceptual, simulation, and predictor types. No consideration is given to programming or computer language; only the principles of modeling and various examples are discussed.

Addendum

Much research has taken place in coastal geology since the publication of Coastal Sedimentary Environments. This additional research and the need to expand the coverage by adding chapters has stimulated this second edition. Each of the original authors has updated and modified his respective chapter. In two of the chapters, co-authors were taken on to help accomplish this task. Especially noticeable is the expansion of the chapters on coastal bays (estuaries) and on coastal sequences. Two new chapters have been added to make the text more comprehensive; one on intertidal flats and one on the shoreface. The need to include the former is obvious, but inclusion of the shoreface may not be. This portion of the inner shelf interfaces with various coastal environments and is integral to a complete understanding of process-response systems operating on the coast

In preparing this revised edition, we have tried to incorporate suggestions made in the various published reviews of the first edition. Although the title implies comprehensive coverage of coasts, virtually all of the discussion is devoted to terrigenous sedimentary environments although basic principles apply to carbonate environments and sediments as well.

Authors

Each of the contributors is an active researcher in the coastal zone, with specialization in the environment for which he is responsible in the book. The authors represent a rather broad spectrum of backgrounds, with research experience being concentrated on the Atlantic and Gulf coasts of the United States, although most have some foreign experience as well.

Dr. Paul B. Basan is a sedimentologist and paleontologist currently involved in research applied to the energy industries. He conducted his doctoral studies on sedimentation in salt marshes under the supervision of his co-author, Dr. R. W. Frey, at the University of Georgia. In addition to his research on salt marshes, Dr. Basan has authored numerous articles on trace fossils.

Dr. Robert B. Biggs is a geological oceanographer with the College of Marine Studies and the Department of Geology at the University of Delaware. Dr. Biggs has studied extensively the trace element geochemistry
