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.

Marine sediments support complex interactions between macro-and microorganisms that have global implications for carbon and nutrient cycles. What is the state of the science on such interactions from coastal and estuarine environments to the deep sea? How does such knowledge effect environmental management? And what does future research hold in store for scientists, engineers, resource managers, and educators?Interactions between Macro- and Microorganisms in Marine Sediments responds to these questions, and more, by focusing on:? Interactions between plants, microorganisms, and marine sediment? Interactions between animals, microorganisms, and marine sediment? Interactions between macro- and microorganisms and the structuring of benthic communities? Impact of macrobenthic activity on microbially-mediated geochemical cycles in sediments? Conceptual and numeric models of diagenesis that incorporate interactions between macro- and microorganismsHere is an authoritative overview of the research, experimentation and modeling approaches now in use in our rapidly evolving understanding of life in marine sediments.

The benthic boundary layer is the zone of water and sediment immediately adjacent to the bottom of a sea, lake, or river. This zone is of considerable interest to biologists, geochemists, sedimentologists, and engineers because of very strong gradients of energy, dissolved and solid chemical components, suspended matter, and the number of organisms that live there. It is, for example, the sink for anthropogenic substances and the home of microscopic plant life that provides the nutrients that determine fish populations--and ultimately the size of the fisheries. This book of original chapters edited by Professors Boudreau and Jorgensen, both leading researchers in the field, will meet the need for an up-to-date, definitive text/reference on measurements, techniques, and models for transport and biochemical processes in the benthic boundary layer. Each chapter provides a comprehensive review of a selected field, with illustrated examples from the authors' own work. The book will appeal to professionals and researchers in marine biology, marine chemistry, marine engineering, and sedimentology.

This book is intended as a monograph for a wide range of scientists in environmental sciences. The focus is placed on the chemistry and biogeochemistry of estuaries but outlines are also given of human and physical factors, biotic transport, and the biological processes necessary for a better understanding of the management of estuaries. Particular attention is paid to the distribution of chlorinated hydrocarbons, oil pollution problems, and the recovery capacity and decontamination of estuaries.

This Volume belongs to a series on Oceanography. It is designed so that it can be read on its own, or used as a supplement in oceanogrphy courses. After a brief introduction to sea-floor sediments, the book shows how the activities of marine organisms cycle nutrients and other dissolved constituents within the oceans, and influence the rates at which both solid and dissolved material is removed to sediments. It goes on to review the carbonate system and shows how sediments that come from continental areas may be transported to the deep sea, explores what sea-floor sediments have taught us about the history of the oceans, and describes the biological and chemical processes that continue long after sediments have been deposited on the deep sea-floor. * Covers the basics on the occurrence, distribution, and cycling of chemical elements in the ocean * Features full-color photographs and beautiful illustrations throughout * Reader-friendly layout, writing, and graphics * Pedagogy includes chapter summaries, chapter questions with answers and comments at the end of the book; highlighted key terms; and boxed topics and explanations * Can be used alone, as a supplement, or in combination with other Open University titles in oceanography

Focuses on the ocean's role in the global biogeochemical cycling of selected elements and the impact of humans on the transport of these elements. Among the topics covered are the chemical composition of seawater from the perspectives of elemental speciation and the impact of solutes on water's physical behavior; biogeochemical phenomena which control accumulation and preservation of marine sediments; marine chemistry of radioactive and stable isotopes; seawater pollution. Contains many examples as well as steady-state models to aid readers in understanding this relatively young, growing and complex science.

Marine systems vary in their sensitivities to perturbation. Perturbation may be insidious - such as increasing eutrophication of coastal areas - or it may be dramatic - such as a response to an oil spill or some other accident. Climate change may occur incrementally or it may be abrupt, and ecosystem resilience is likely to be a complex function of the interactions of the factors and species mediating key biogeochemical processes. Biogeochemistry of Marine Systems considers issues of marine system resilience, focusing on a range of marine systems that exemplify major global province types. Each system is interesting in its own right, on account of its sensitivity to natural or anthropogenic change or its importance as an ecological service provider. Each contributing author concentrates on advances of the last decade. This prime reference source for marine biogeochemists, marine ecologists, and global systems scientists provides a strong foundation for the study of the multiple marine systems undergoing change because of natural biochemical or anthropogenic factors.
