Book Description
Derived from an unprecedented research effort covering over 31 years in a series of studies of 7 major river-estuaries, Eutrophication Processes in Coastal Systems presents a comprehensive and current review of the nature of the eutrophication process and how short- and long-term nutrient loading affects marine systems. This unique book is the culmination of the most advanced research to date on how coastal systems work. Based on an 11 year interdisciplinary study of the Perdido Bay System, Dr. Robert J. Livingston's groundbreaking work offers evidence for significant findings such as: Nutrient concentration gradients in fresh water as it entered the bay were stimulatory to phytoplankton blooms Species that showed distinctive seasonal and interannual successions dominated plankton blooms High relative dominance of bloom species was associated with significant reduction of phytoplankton species richness and diversity The blooms were associated with major reductions of infaunal and epibenthic macroinvertibrates, forcing a serious disruption of the food webs and losses of secondary production Eutrophication Processes in Coastal Ecosystems goes beyond its innovative analyses of how estuarine and coastal systems have responded to fundamental alterations of the eutrophication process. Dr. Livingston's book presents the case that bloom impacts must be reviewed against the background conditions that include periodic changes brought on by drought and anthropogenous dredging. It points to the critical need for further study of phytoplankton communities and the connection between plankton blooms, sediment deterioration, and low secondary production.

Book Description
Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

Book Description
Coastal eutrophication has been and still remains an important issue for the scientific community. Despite many efforts to mitigate coastal eutrophication, the problems associated with eutrophication are still far from being solved. This book focusses on the most recent scientific results in relation to specific eutrophication issues, e.g. definition(s) and causes; nutrient loads, cycling and limitation; reference conditions, primary effects and secondary effects; trend reversal (oligotrophication), as well as links to other pressures (climate change and top/down control). It also focusses on monitoring and modelling of coastal eutrophication, and adaptive and science-based nutrient management strategies. The book is based on selected papers from the Second International Symposium on Research and Management of Eutrophication in Coastal Ecosystems, held 20-23 June 2006 in Nyborg, Denmark.

Book Description
Derived from an unprecedented research effort covering over 70 field years of field data in a series of studies, Trophic Organization in Coastal Systems represents an alternative approach to coastal research that has been successfully applied to coastal resource management issues. This unique book is based upon a sequence of long-term, interdisciplinary studies of a series of coastal regions in the NE Gulf of Mexico that include nutrient loading, habitat definition, quantified collections of organisms from microbes to fishes, and the determination of the trophic organization that defines the processes that shape the productivity of these areas. A multidisciplinary team of marine scientists, chemists, physical oceanographers, geologists, hydrologists, engineers, experimental biologists, and taxonomists have created a singular database of changes in a series of Gulf of Mexico coastal systems. This field information, together with field and laboratory experimentation, is integrated with the scientific literature to advance our understanding of how coastal food webs work. The central focus is on the relationship of primary production in the form of species-specific phytoplankton communities with associated food webs of coastal systems and the relationship of tropho-dynamic processes to long-term changes (natural and polluted) in such areas. The impacts of phytoplankton blooms on trophic organization is elucidated. The author, a renowned marine scientist, provides detailed knowledge of the processes that drive coastal ecosystems. He presents an in-depth discussion of a hierarchy of cyclical periods associated with the formation and development of aquatic food webs. Trophic Organization in Coastal Systems will be particularly useful to those involved in research related to the importance of aquatic food webs to an understanding of how aquatic systems function. The principles and processes of trophic organization presented here can serve as a valuable model for research in other regions of the world.

Book Description
Coastal zones play a key role in Earth System functioning and form an “edge for society” providing a significant contribution to the life support systems. Goods and services derived from coastal systems depend strongly on multiple transboundary interactions with the land, atmosphere, open ocean and sea bottom. Increasing demands on coastal resources driven by human habitation, food security, recreation and transportation accelerate the exploitation of the coastal landscape and water bodies. Many coastal areas and human activities are subject to increasing risks from natural and man-induced hazards such as flooding resulting from major changes in hydrology of river systems that has reached a global scale. Changes in the hydrological cycle coupled with changes in land and water management alter fluxes of materials transmitted from river catchments to the coastal zone, which have a major effect on coastal ecosystems. The increasing complexity of underlying processes and forcing functions that drive changes on coastal systems are witnessed at a multiplicity of temporal and spatial scales.

Book Description
Coastal ecosystems make up some of the most important and, yet, most endangered, regions in the world. The protection of the unique processes that take place in these ecosystems requires that partnerships be formed among ecologists, resource managers and planners. Experienced in the challenges of coastal system analysis, the contributors to this book provide multidisciplinary guidance on the assessment and management of environmental impacts caused by development. Each chapter examines an issue important to these fragile ecosystems, first presenting a non-technical summary of the issue and a review of the current state of the knowledge, then following with data and a more detailed consideration of the topic. Functioning both as a practical guide, accessible to nonscientists, and as a rigorous scientific source book, Changing Land Use Patterns in the Coastal Zone will be useful to ecologists, urban and regional planners, resource managers, policymakers and students. While many of the case studies included in this volume are drawn from studies in the southeastern United States, the examples and lessons provided will be relevant to those working in all coastal environments.

Book Description
Close to one-half of all Americans live in coastal counties. The resulting flood of wastewater, stormwater, and pollutants discharged into coastal waters is a major concern. This book offers a well-delineated approach to integrated coastal management beginning with wastewater and stormwater control. The committee presents an overview of current management practices and problems. The core of the volume is a detailed model for integrated coastal management, offering basic principles and methods, a direction for moving from general concerns to day-to-day activities, specific steps from goal setting through monitoring performance, and a base of scientific and technical information. Success stories from the Chesapeake and Santa Monica bays are included. The volume discusses potential barriers to integrated coastal management and how they may be overcome and suggests steps for introducing this concept into current programs and legislation. This practical volume will be important to anyone concerned about management of coastal waters: policymakers, resource and municipal managers, environmental professionals, concerned community groups, and researchers, as well as faculty and students in environmental studies.
