Book Description
This book examines the processes that create and sustain anoxia (the absence of oxygen) and hypoxia (the near absence of oxygen) in bottom waters of the Chesapeake Bay. The authors of the book's four chapters discuss major findings and summarize the gradually developing consensus on the implications of these findings for resource management. William C. Boicourt focuses on the physical aspects of Chesapeake Bay in order to distinguish the role and relative importance of circulation processes in the creation of low dissolved oxygen levels. Thomas C. Malone examines the role of water column processes, including the importance and interaction of nutrients, phytoplankton and zooplankton. Robert Jonas discusses the significance of microbial populations, while W. Michael Kemp and Walter R. Boynton discuss the role and importance of benthicpelagic coupling on Chesapeake Bay dissolved oxygen.

Book Description
Hypoxia occurs when dissolved oxygen falls below the level necessary to sustain most animal life, often due to fertilizer run-off. This volume reviews how the expanding hypoxic zone in the northern Gulf of Mexico has affected living resources in the Louisiana/Texas shelf. Topics of the 23 chapters include impacts of changing Si/N ratios and phytoplankton species composition, the effect of hypoxia and anoxia on the supply and settlement of benthic invertebrate larvae, and ecological effects of hypoxia in fish, sea turtles, and marine mammals. c.

Book Description
This unique book focuses attention on the failure of current efforts to cleanup the Chesapeake Bay and suggests an approach often used in cleaning up environmentally damaged sites While military munitions sources contribute significantly to the pollution and degradation of Chesapeake Bay, they have been completely overlooked in many of the efforts to restore the Bay. Death of the Chesapeake explores this important aspect of the nation's environmental health. The book also recognizes for the first time that efforts to restore the Bay have failed because of the violation of a fundamental precept of environmental cleanup; that is, to sample the site and see what's there. The Bay itself has never been sampled. Thus, this book presents a view of the environmental condition of Chesapeake Bay that is totally unique. It covers a part of the history of the Bay that is not widely known, including how the Bay was formed. It presents a mixture of science, military history, and novel solutions to the Bay's degradation. In so doing, the author examines the military use of the Bay and reveals the extent that munitions dumpsites containing nitrogen and phosphorus as well as chemical warfare material are affecting the environment. The book concludes with the author's own cleanup plan, which, if implemented, would go a long way toward restoring health to the Bay. The book is supplemented with many photographs and maps.

Book Description
The study of estuaries and coasts has seen enormous growth in recent years, since changes in these areas have a large effect on the food chain, as well as on the physics and chemistry of the ocean. As the coasts and river banks around the world become more densely populated, the pressure on these ecosystems intensifies, putting a new focus on environmental, socio-economic and policy issues. Written by a team of international expert scientists, under the guidance of Chief Editors Eric Wolanski and Donald McClusky, the Treatise on Estuarine and Coastal Science, Ten Volume Set examines topics in depth, and aims to provide a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Most up-to-date reference for system-based coastal and estuarine science and management, from the inland watershed to the ocean shelf Chief editors have assembled a world-class team of volume editors and contributing authors Approach focuses on the physical, biological, chemistry, ecosystem, human, ecological and economics processes, to show how to best use multidisciplinary science to ensure earth's sustainability Provides a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Features up-to-date chapters covering a full range of topics

Book Description
This environmental history of America’s largest estuary provides insight into how and why its former productivity and abundant fisheries have declined. The concept of “shifting baselines”—changes in historical reference points used in environmental assessments—illuminates a foundational challenge when evaluating the health of ecosystems and seeking to restore degraded wildlife populations. In this important book, Victor S. Kennedy examines the problem of shifting baselines for one of the most productive aquatic resources in the world: the Chesapeake Bay. Kennedy explains that since the 1800s, when the Bay area was celebrated for its aquatic bounty, harvest baselines have shifted downward precipitously. Over the centuries, fishers and hunters, supported by an extensive infrastructure of boats, gear, and processing facilities, overexploited the region’s fish, crustaceans, terrapin, and waterfowl, squandering a profound resource. Beginning with the colonial period and continuing through the twentieth century, Kennedy gathers an unparalleled collection of scientific resources and eyewitness reports by colonists, fishers, managers, scientists, and newspaper reporters to create a comprehensive examination of the Chesapeake’s environmental history. Focusing on the relative productivity and health of its fisheries and wildlife and highlighting key species such as shad, oysters, and blue crab, Shifting Baselines in the Chesapeake Bay helps readers understand the remarkable extent of the Bay’s natural resources in the past so that we can begin to understand what has changed since, and why. Such knowledge can help illustrate the Bay’s potential fertility and stimulate efforts to restore this pivotal maritime system’s ecological health and productivity.
