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.

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.

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.

Produced by a Leading Aquatic Scientist A narrative account of how estuaries around the world are being altered by human forces and human-induced global climate changes, Climate Change and Coastal Ecosystems: Long-Term Effects of Climate and Nutrient Loading on Trophic Organization chronicles a more than 40-year-old research effort conducted by Dr. Robert J. Livingston and his research team at Florida State University. Designed to evaluate system-level responses to natural and anthropogenic nutrient loading and long-term climate changes, the study focused on the northeast Gulf of Mexico river–bay systems, and concentrated on phytoplankton/benthic macrophyte productivity and associated food web organization. It addressed the changes of food web structure relative to long-term trends of climatological conditions, and was carried out using a combination of field-descriptive and experimental approaches. Details Climate Change, Climate Change Effects, and Eutrophication This book includes comparative analyses of how the trophic organization of different river–bay ecosystems responded to variations of both anthropogenic impacts and natural driving factors in space and time. It incorporates a climate database and evaluates the effects of climate change in the region. It also provides insights into the effects of nutrient loading and climate on the trophic organization of coastal systems in other global regions. Presents research compiled from consistent field sampling methods and detailed taxonomic identifications over an extended period of study Includes the methods and materials that the research team used to access the health and trophic organization of Florida’s estuaries Provides an up-to-date bibliography of estuarine publications and reports Based on a longitudinal study of anthropogenic and natural driving factors on river-estuarine systems in the northeast Gulf of Mexico, Climate Change and Coastal Ecosystems: Long-Term Effects of Climate and Nutrient Loading on Trophic Organization is useful as a reference for researchers working on riverine, estuarine, and coastal marine systems.

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.

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.

For many years the reduction of eutrophication in the Baltic Sea has been a hot issue for mass-media, science, political parties and environmental action groups with manifold implications related to fisheries (will the Baltic cod survive?), sustainable coastal development (have billions of Euros been wasted on nitrogen reductions?), ecotoxicology (can we safely eat Baltic fish?). This book takes a holistic process-based ecosystem perspective on the eutrophication in the Baltic Sea, with a focus on the factors regulating how the system would respond to changes in nutrient loading. This includes a very special process for the Baltic Sea: land uplift. After being depressed by the glacial ice, the land is now slowly rising adding vast amounts of previously deposited nutrients and clay particles to the system. 110,000 to 140,000 tons of phosphorus per year are added to the system from land uplift, in comparison to the 30,000 tons of phosphorus per year from rivers.
