Book Description
Microbial Communities in Coastal Sediments: Structure and Functions presents research gained on coastal microbiology over the past two decades. The book covers the source of organic matter, which is found to design sediment microbial communities, and goes on to consider the quality of this matter with regard to degradation in coastal sediment. The book explores human induced changes in coastal ecosystems, then later focuses on the availability of nutrients, source of persistent organic pollutants (POPs) in the sediment, and the sequencing of microbial structures and functions when using molecular tools. Despite the years of research, this is the first book to focus purely on coastal microbes in coastal ecosystems. As such, it is for gaining a better understanding of the diversity and functions of different types of microbes in coastal ecosystems across the globe. The book outlines the microbial community structure in marine sediments while also elaborating on the methods of assessment of the microbial community, making it of great relevance to aquatic microbiologists, marine ecologists, marine microbiologists, aquatic researchers, and scientists alike. Presents data on physico-chemical and biological features of coastal ecosystems and microbial community composition, allowing researchers to compare their data with pre-existing data Includes unique figures, schematic diagrams and photographs related to microbial processes of coastal ecosystems, providing a clear representation on the different aspects of microbial structure and functions Provides analytical methods and detailed molecular techniques for qualitative and quantitative analyses of microbial community structure, enabling scientists and students to follow the protocols provided in the book for assessment in their own research

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
The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.

Eutrophication continues to be a major global challenge to water quality scientists. The global demand on water resources due to population increases, economic development, and emerging energy development schemes has created new environmental challenges to global sustainability. Eutrophication, causes, consequences, and control provides a current account of many important aspects of the processes of natural and accelerated eutrophication in major aquatic ecosystems around the world. The connections between accelerated eutrophication and climate change, chemical contamination of surface waters, and major environmental and ecological impacts on aquatic ecosystems are discussed. Water quality changes typical of eutrophication events in major climate zones including temperate, tropical, subtropical, and arid regions are included along with current approaches to treat and control increased eutrophication around the world. The book provides many useful new insights to address the challenges of global increases in eutrophication and the increasing threats to biodiversity and water quality.

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.
