Polluted Coastal Waters

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.

Nearly 60% of the world's population lives and works within 100 miles of a coast, and even those who don't are connected to the world's oceans through an intricate drainage of rivers and streams. Ultimately the whole of humankind is coastal.Coastal Waters of the World is a comprehensive reference source on the state of the world's coastal areas. It focuses on the tremendous pressures facing coastal areas and the management systems and strategies needed to cope with them. Don Hinrichsen explores the origins and implications of three related issues: the overwhelming threats to our coastal resources and seas from population and pollution; the destruction of critical resources through unsustainable economic activity; and the inability of governments to craft and implement rational coastal management plans.Introductory chapters present a concise summary of our coastal problems, including coastal habitat degradation and the fisheries crisis, along with a discussion of better management options. Three case studies of successful coastal governance focus on some of the problems and bring to life potential solutions. Following that are regional profiles that provide detailed information on the main population, resource, and management challenges facing each of the world's thirteen major coastal waters and seas. The profiles are presented in a standard format to allow for ease of comparison between regions, and accessibility of information. The book ends with a realistic and practical agenda for action that can be implemented immediately.Safeguarding these complex, interlinked ecosystems is humanity's most challenging management job. Coastal Waters of the World will help raise our awareness of coastal area concerns and provide a constructive contribution to the ongoing debate over how to manage these ever-changing areas, both for ourselves and for future generations. It will serve as a valuable reference tool and an up-to-date resource for policymakers, management specialists, and students interested in sustainable coastal governance.

During the recent decades, social, political and academic endeavours have been made to improve environmental quality and reduce pollution. In particular, the ocean, sea and coastal areas show varying degrees of impact from the multiple human activities carried out in the terrestrial as well as in the aquatic environment. Ecology is a science which studies the relationship between organisms and the surrounding environment and in the modern era, the marine world is getting increasing attention. For centuries it has been the final reservoir of human garbage; later it became an oil farm with a concomitant increase of coastal population growth and unplanned growth of the fishing industry and the increasing use of sea routes for cargo transport and recreational uses (cruises). All this led to rising contamination with negative effects on biota and even human health. It is then imperative to know the current situation of the world's oceans: that is the main purpose of this book, to document at a glance the latest research in the field of ocean pollution.

Understanding marine pollution and the contamination of coastal environments requires knowledge from a variety of scientific fields. Marine Environmental Quality promotes a multidisciplinary approach to investigations, drawing on not only natural sciences, but also applied mathematics and social sciences. The investigations in this book focus on both organic and inorganic pollutants, firstly in a study conducted in the city of La Rochelle, on the North Atlantic French coast, then expanding the areas under examination to regions of English and Portuguese waters and, lastly, to the Mediterranean Sea. The improvement such research can bring to biomarkers, models and experiments enables equal progress in the quality of seawater in ports and protected areas of coastal regions. The eight chapters of Marine Environmental Quality present many aspects of this research, including experiments with floating barriers, water governance in various areas, sampling sites and sentinel species that act as biomarkers in harbors. Also covered are environmental commitments, both international and local, the risk that marine contamination poses to human health, experimental designs for interactions with microplastics and a study biomonitoring the juveniles of sentinel species. Such results will bring many benefits, to human health, to economic inclusion and to regional development.

In 1996, after more than a decade of researching the effects of over-population and the consequent pollution of the greater metropolitan New York City area, Carl Sindermann published his observations and conclusions in Ocean Pollution: Effects on Living Resources and Humans, a mostly technical document that emphasized the pathological effects of co

The first comprehensive overview of the enormous ecological diversity of Baltic coastal ecosystems is presented in this volume provides. A short introduction into the Baltic Sea as a reference ecosystem is followed by detailed descriptions of the characteristics of coastal ecosystems. Ecological case studies from four regions illustrate the different reactions of these ecosystems to natural and anthropogenic influences.
