Book Description
Oceanographic discontinuities (e. g. frontal systems, upwelling areas, ice edges) are often areas of enhanced biological productivity. Considerable research on the physics and biology of the physical boundaries defining these discontinues has been accomplished (see [I D. The interface between water and sediment is the largest physical boundary in the ocean, but has not received a proportionate degree of attention. The purpose of the Nato Advanced Research Workshop (ARW) was to focus on soft-sediment systems by identifying deficiencies in our knowledge of these systems and defining key issues in the management of coastal sedimentary habitats. Marine sediments play important roles in the marine ecosystem and the biosphere. They provide food and habitat for many marine organisms, some of which are commercially important. More importantly from a global perspective, marine sediments also provide "ecosystem goods and services" [2J. Organic matter from primary production in the water column and contaminants scavenged by particles accumulate in sediments where their fate is determined by sediment processes such as bioturbation and biogeochemical cycling. Nutrients are regenerated and contaminants degraded in sediments. Under some conditions, carbon accumulates in coastal and shelf sediments and may by removed from the carbon cycle for millions of years, having a potentially significant impact on global climate change. Sediments also protect coasts. The economic value of services provided by coastal areas has recently been estimated to be on the order of $12,568 9 10 y" [3J, far in excess of the global GNP.

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
Marine sediments dominate the global seabed, creating the largest ecosystem on earth. Seafloor biodiversity is a key mediator of ecosystem functioning, yet critical processes are often excluded from global biogeochemical budgets or simplified to black boxes in ecosystem models. This accessible textbook provides an ideal point of entry into the field, providing basic information on the nature of soft-sediment ecosystems, examples of how and why we research them, the new questions these studies inspire, and the applications that ultimately benefit society. While focussing on coastal habitats (

Book Description
Studies of marine ecology have traditionally been approached through lectures and field courses devoted mainly to intertidal and inshore habitats, and it is surprising in these days of increased awareness of man's environmental impact that so little attention has been given to integrated approaches involving the whole coastal zone and including the terrestrial part, which is man's major habitat. The coastal zone has been the subject of extensive investigation, not only because of its biological diversity and accessibility, but also because of its economic and aesthetic importance to man. This book is written with the intention of providing a concise but readable account of coastal ecology for advanced undergraduates and immediate postgraduates. We have adopted a habitat-organismal ap proach because we believe that a knowledge of biota and major features of their environment is the best key to an understanding of both larger-scale processes, such as energy flow and nutrient cycling, and smaller-scale but equally fundamental processes, such as behavioural and physiological ecology. Examples have been selected from polar, temperate and tropical regions of the world. The breadth of the subject has dictated selectivity from sources too numerous to acknowledge individually, but we have included an up-to-date reference list for the main subjects of each chapter.

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
Organic matter in aquatic environments consists mostly of large compounds which cannot be taken up and utilized directly by microbial cells. Prior to incorporation, polymeric materials undergo degradation by cell-bound and extracellular enzymes produced by these microbes; in fact, such enzymatic mobilization and transformation is the key process which regulates the turnover of organic as well as inorganic compounds in aquatic environments. This volume brings together studies on enzymatic degradation processes from disciplines as diverse as water and sediment research, bacterial and algal aquatic ecophysiology, eutrophication, and nutrient cycling and biogeochemistry, in both freshwater and marine ecosystems. Its scope extends from fundamental research exploring the contribution of microbial enzymatic processes to whole ecosystem functioning to practical applications in water biotechnology. The first comprehensive publication providing an overview of this emerging field of enzymology, Microbial Enzymes in Aquatic Environments will be of great interest to ecologists and microbiologists alike.

Book Description
The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

Book Description
Sedimentary coasts with their unique forms of life and productive ecosystems are one of the most threatened parts of the biosphere. This volume analyzes and compares ecological structures and processes at sandy beaches, tidal mudflats and in shallow coastal waters all around the world. Analyses of local processes are paired with comparisons between distant shores, across latitudinal gradients or between separate biogeographic provinces. Emphasis is given to suspension feeders in coastal mud and sand, to biogenic stabilizations and disturbances in coastal sediments, to seagrass beds and faunal assemblages across latitudes and oceans, to recovery dynamics in benthic communities, shorebird predation, and to experimental approaches to the biota of sedimentary shores.
