Microbiology of Extreme Soils
This volume provides an excellent introduction to the study of extreme soil micro-biology, and a variety of the challenging and fascinating environments that Earth-bound microbes face. Some are natural, and some are the result of human activity, and all of them have lessons to teach us about life’s adaptations within the “extreme” hori-zons of terrestrial soils. What’s more, each of these chapters (including the chapter on the soils of Mars by Ronald L. Crawford and David A. Newcombe) can give us insights into strategies that may make life possible beyond the safe confines of our present-day biosphere, to other worlds in this solar system and beyond
International conference on terrain and geohazard challenges facing onshore oil and gas pipelines : Evaluation, routing, resign, construction, operation ; Proceedings of a three day international conference on terrain and geohazard challenges facing onshore oil and gas pipelines, organised by the Institution of Civil Engineers in association with BP Exploration and held at the Institution of Civil Engineers, London, UK, on 2 – 4 June 2004
To access global oil and gas deposits, major pipelines must traverse remote regions with extreme terrains. There are a significant number of pipeline projects, active or planned, in tropical jungles, mountains and deserts, in permafrost and in areas of wetland. Each of these natural environments is associated with a range of geohazards, which may include landslides, soil erosion, karst, river migration, and seismic or volcanic activity. At the same time, society demands increasing availability and reliability of supply, together with improved environmental standards, all making for substantial challenges.
Geology and Ecosystems
This book includes an analysis of the relationship between the different geological, hydrochemical, hydrogeological and engineering-geological processes and the processes within surface ecosystems. The analysis of specific interactions between the lithosphere and biosphere provides an integrated concept of the role of the geological environment in the evolution of the biosphere. The practical significance of the book is reflected by the analysis of modern engineering activity associated with the mining of minerals, excessive groundwater withdrawal, disposal of industrial and domestic wastes (including radioactive wastes) and their impacts on all components of the environment. Geology and Ecosystems includes a scientific approach to the complex monitoring of the environment under different natural and anthropogenic conditions, including the monitoring of permafrost regions. An important part of the book is the analysis of the "water factor" impact on ecosystems and sustainable development. Influences of intensive groundwater extraction on river flow, vegetation and land subsidence are also considered.
Economic Geology of Natural Gas Hydrate
This is the first book that attempts to broadly integrate the most recent knowledge in the fields of hydrate nucleation and growth in permafrost regions and marine sediments. Gas hydrate reactant supply, growth models, and implications for pore fill by natural gas hydrate are discussed for both seawater precursors in marine sediments and for permafrost hydrate. These models for forming hydrate concentrations that will constitute targets for exploration are discussed, along with exploration methods. Thermodynamic models for the controlled conversion of hydrate to natural gas, which can be recovered using conventional industry practices, suggest that a number of different types of hydrate occurrence are likely to be practical sources of hydrate natural gas. Current progress in the various aspects of commercial development of hydrate gas deposits are discussed, along with the principal extractive issues that have yet to be resolved.
Landslides : Risk Analysis and Sustainable Disaster Management
Based on contributions to the first General Assembly of the International Consortium on Landslides, this reference and status report emphasizes the mechanisms of different types of landslides, landslide risk analysis, and sustainable disaster management. It comprises the achievements of the ICL over the past three years, since the Kyoto assembly. It consists of three parts: research results of the International Programme on Landslides (IPL); contributions on landslide risk analysis; and articles on sustainable disaster management. The contributions reflect a wide range of topics and concerns, randing from field studies, identification of objects of cultural heritage at landslide risk, as well as landslide countermeasures.
