Book Description
Nitrogen in the Marine Environment provides information pertinent to the many aspects of the nitrogen cycle. This book presents the advances in ocean productivity research, with emphasis on the role of microbes in nitrogen transformations with excursions to higher trophic levels. Organized into 24 chapters, this book begins with an overview of the abundance and distribution of the various forms of nitrogen in a number of estuaries. This text then provides a comparison of the nitrogen cycling of various ecosystems within the marine environment. Other chapters consider chemical distributions and methodology as an aid to those entering the field. This book discusses as well the enzymology of the initial steps of inorganic nitrogen assimilation. The final chapter deals with the philosophy and application of modeling as an investigative method in basic research on nitrogen dynamics in coastal and open-ocean marine environments. This book is a valuable resource for plant biochemists, microbiologists, aquatic ecologists, and bacteriologists.

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
Estuarine Ecology A detailed and accessible exploration of the fundamentals and the latest advances in estuarine ecology In the newly revised third edition of Estuarine Ecology, a team of distinguished ecologists presents the current knowledge in estuarine ecology with particular emphasis on recent trends and advances. The book is accessible to undergraduate students while also providing a welcome summary of up-to-date content for a more advanced readership. This latest edition is optimized for classroom use, with a more intuitive mode of presentation that takes into account feedback from the previous edition’s readers. Review questions and exercises have been added to assist in the learning and retention of complex concepts. Estuarine Ecology remains the gold standard for the discipline by taking stock of the manifold scientific breakthroughs made in the field since the last edition was written. It also offers: Thorough introductions to estuarine geomorphology, circulation, and chemistry In-depth treatments of estuarine primary and secondary production, including coastal marshes and mangrove wetlands A holistic view of estuarine ecosystems, their modeling and analysis, as well as the impact of human activities and climate change A companion website with detailed answers to exercise questions Perfect for students of estuarine ecology, environmental science, fisheries science, oceanography, and natural resource management, Estuarine Ecology will also earn a place in the libraries of professionals, government employees, and consultants working on estuary and wetlands management and conservation.

Book Description
Tidal salt marshes are viewed as critical habitats for the production of fish and shellfish. As a result, considerable legislation has been promulgated to conserve and protect these habitats, and much of it is in effect today. The relatively young science of ecological engineering has also emerged, and there are now attempts to reverse centuries-old losses by encouraging sound wetland restoration practices. Today, tens of thousands of hectares of degraded or isolated coastal wetlands are being restored worldwide. Whether restored wetlands reach functional equivalency to `natural' systems is a subject of heated debate. Equally debatable is the paradigm that depicts tidal salt marshes as the `great engine' that drives much of the secondary production in coastal waters. This view was questioned in the early 1980s by investigators who noted that total carbon export, on the order of 100 to 200 g m-2 y-1 was of much lower magnitude than originally thought. These authors also recognized that some marshes were either net importers of carbon, or showed no net exchange. Thus, the notion of `outwelling' has become but a single element in an evolving view of marsh function and the link between primary and secondary production. The `revisionist' movement was launched in 1979 when stable isotopic ratios of macrophytes and animal tissues were found to be `mismatched'. Some eighteen years later, the view of marsh function is still undergoing additional modification, and we are slowly unraveling the complexities of biogeochemical cycles, nutrient exchange, and the links between primary producers and the marsh/estuary fauna. Yet, since Teal's seminal paper nearly forty years ago, we are not much closer to understanding how marshes work. If anything, we have learned that the story is far more complicated than originally thought. Despite more than four decades of intense research, we do not yet know how salt marshes function as essential habitat, nor do we know the relative contributions to secondary production, both in situ or in the open waters of the estuary. The theme of this Symposium was to review the status of salt marsh research and revisit the existing paradigm(s) for salt marsh function. Challenge questions were designed to meet the controversy head on: Do marshes support the production of marine transient species? If so, how? Are any of these species marsh obligates? How much of the production takes place in situ versus in open waters of the estuary/coastal zone? Sessions were devoted to reviews of landmark studies, or current findings that advance our knowledge of salt marsh function. A day was also devoted to ecological engineering and wetland restoration papers addressing state-of-the-art methodology and specific case histories. Several challenge papers arguing for and against our ability to restore functional salt marshes led off each session. This volume is intended to serve as a synthesis of our current understanding of the ecological role of salt marshes, and will, it is hoped, pave the way for a new generation of research.

Book Description
The image is modified based on Figure 1a of Lucey et al. (this Research Topic) and Figure 7b of Niemi et al. (this Research Topic). (A) Graphical depiction of atmospheric warming and increasing atmospheric carbon dioxide (CO2atm), which drives ocean warming, contribute to the decreases in dissolved oxygen (DO), and lowers pH and saturation state index of calcium carbonate (Ω). The partial pressure of CO2 (pCO2) increases due to increasing atmospheric CO2 that is absorbed into the seawater (i.e., ocean acidification), along with other biological processes in the marine environment.

Book Description
Written by an outstanding group of contributors, this book examines the function and structure of coastal lagoonal ecosystems and the natural and anthropogenic drivers of change that affect them, most notably nutrient over-enrichment from coastal watersheds and airsheds. The contributors target the susceptibility of coastal lagoons to eutrophication, the indicators of eutrophic conditions, the influences of natural factors such as major storms and other climate effects, and the resulting biotic and ecosystem impairments that have developed. The book compares biogeochemical and ecological response to nutrient enrichment and other pollutants in lagoonal estuaries to those in other estuarine types.
