Book Description
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.

Book Description
This report describes a sediment transport model being developed for modelling the dispersion and transport of suspended sediment in the benthic boundary layer on the continental shelf. A key feature of the model is the simplified representation of vertical mixing through the random shuffling of packets of material and the use of observational suspended sediment profiles as probability density functions for the overall vertical distribution. Horizontal transport is then represented through advection of the packets in vertically- and time-varying flow fields taken from observations or from a numerical circulation model. The effective horizontal dispersion rates in the model are consistent with fundamental ideas about shear dispersion. The report includes results of numerical experiments illustrating the effects of different current regimes, vertical distribution rates, and mixing rates on dispersion of seabed drilling discharges.

Book Description
The Conference on the Benthic Boundary Layer was held under the auspices of the NATO Science Committee as part of its continuing effort to promote the useful progress of science through international cooperation. Science Committee Conferences are deliberately designed to focus attention on unsolved problems, with carefully selected participants invited to provide complementary expertise from a variety of relevant disciplines. Through inten sive discussion in small groups they seek to reach a consensus on assessments and recommendations for future research emphasis, which it is hoped will be of value to the larger scientific community. The subjects treated over the past few years have been as varied as science itself-e.g., computer software engineering, chemical catalysis, and materials and energy research. The present effort evolved from informal discussions between marine geolo gists, chemists, and biologists which underlined the desirability of improved communication among those concerned with the benthic layer. In both scien tific and technological terms this is an exciting frontier, rich in promise but poorly understood at present. It is particularly striking to realize that there are at least as many definitions of the benthic layer as there are disciplines involved, and it seemed clear that there was much to be gained by a detailed exchange of views on research capabilities, trends, and priorities. The results of the meeting appear to have confirmed the hopes of the sponsors.
