This timely book presents the state-of-the-art of our knowledge of the nature and chemical structure of redox interfaces in a marine water column, oxygen depletion and connected processes. The structures of the redox layers, including the distribution of certain parameters and microbiological features, are described in detail. The volume also covers studies devoted to the interannual variability of some oxygen-depleted systems, modeling and new developments in observation techniques. In addition, it identifies remaining gaps in our knowledge of the cycling of chemical elements in changing redox conditions. The chapters are based on extensive observational data, collected by the authors during sea and shore expeditions, on archive data, and on a broad range of scientific literature.
Many areas of geomicrobial processes are receiving serious attention from microbiologists, specifically the role microbes play in the formation and degradation of minerals and fossil fuels and elemental cycling. Most notably, the latest research finds that microbes have a more direct impact on the transformation of oxidizable and reducible minerals than was previously believed. Following in the footsteps of its prior editions, Geomicrobiology, Fifth Edition serves as an introduction to this globally pertinent field and as an up-to-date reference reflecting recent groundbreaking advances.
Includes an Array of Detailed Illustrations
Authored by two of the leading authorities in the field, this book illuminates the processes by which bacteria catalyze geomicrobial reactions. Generously laden with tables, graphics, diagrams, photographs, and illustrations, this all-encompassing reference examines the geomicrobial aspects of a wide range of minerals, including aluminum- and arsenic-containing minerals, and various fossil fuels.
Examines Geomicrobial Interactions with:
One of life’s great mysteries is how it sustains itself even in seemingly inhospitable environments, such as the deep subsurface. The authors anticipate that as mechanistic molecular approaches are increasingly applied to diverse problems in geomicrobiology, this and other fundamental puzzles will be resolved.
This book explores these questions in an interdisciplinary approach, and examines the mode and nature of links between geological processes and microbial activities and their significance for the origin and evolution of life on the Earth and possibly on other planets.
*The classic text, fully updated to reflect the rapid pace of discovery
*Provides researchers and students in oceanography, chemistry, and marine ecology an understanding of the marine nitrogen cycle
*Available online with easy access and search - the information you need, when you need it
In order to explain our observations from deep subsurface ecosystems it is necessary to develop truly interdisciplinary approaches, ranging from microbiology and geochemistry to physics and modeling.
This book aims to bring together a wide variety of topics, covering the broad range of issues that are associated with deep biosphere exploration. Not only does the book present case studies of selected projects, but also treats questions arising from our current knowledge. Despite nearly two decades of research, there are still many boundaries to exploration caused by technical limitations and one section of the book is devoted to these technical challenges and the latest developments in this field. This volume will be of high interest to biologists, chemists and earth scientists all working on the deep biosphere.
