Download or read book Volcanic Ash Soils written by S. Shoji and published by Elsevier. This book was released on 1994-01-06 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcanic eruptions are generally viewed as agents of destruction, yet they provide the parent materials from which some of the most productive soils in the world are formed. The high productivity results from a combination of unique physical, chemical and mineralogical properties. The importance and uniqueness of volcanic ash soils are exemplified by the recent establishment of the Andisol soil order in Soil Taxonomy. This book provides the first comprehensive synthesis of all aspects of volcanic ash soils in a single volume. It contains in-depth coverage of important topics including terminology, morphology, genesis, classification, mineralogy, chemistry, physical properties, productivity and utilization. A wealth of data (37 tables, 81 figures, and Appendix) mainly from the Tohoku University Andisol Data Base is used to illustrate major concepts. Twelve color plates provide a valuable visual-aid and complement the text description of the world-wide distribution for volcanic ash soils.This volume will serve as a valuable reference for soil scientists, plant scientists, ecologists and geochemists interested in biogeochemical processes occurring in soils derived form volcanic ejecta.

Download or read book ECOL SOUTHERN CONIFERS written by Neal J. Enright and published by Smithsonian Books (DC). This book was released on 1995 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: "While pines, spruces, firs, and other conifers prominent in northern hemisphere landscapes, particularly in mountain and high-altitude environments, have been the subject of much scientific study, southern conifers have been largely overlooked, even though almost one-third of all conifers - some 200 speciesare found in the southern hemisphere and many more occur in the tropical lowland forests that straddle the equator. Some researchers have even characterized the southern conifers as relicts or living fossils, destined to be swept away by a rising tide of flowering plants." "Ecology of the Southern Conifers brings together, for the first time, information on this diverse and unique group of plants. Twenty-eight scholars from around the world examine the history and ecology of the southern conifers, and emphasize their importance in understanding the evolution and ecological dynamics of southern vegetation. Drawing together the results of research from ecosystems as varied as the South African fynbos and New Caledonian rainforests, the Argentine steppe and inland Australia, this book searches for unifying themes and seeks to relate these to modern evolutionary and ecological theory." "Ecology of the Southern Conifers demonstrates the plants' significance for understanding evolutionary and ecological processes in the southern hemisphere."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Download or read book Geothermal Resources written by R. Bowen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the Arab oil embargo of 1974, it has been clear that the days of almost limitless quantities of low-cost energy have passed. In addition, ever worsening pollution due to fossil fuel consumption, for instance oil and chemical spills, strip mining, sulphur emission and accumulation of solid wastes, has, among other things, led to an increase of as much as 10% in the carbon dioxide content of the atmosphere in this century. This has induced a warming trend through the 'greenhouse effect' which prevents infrared radiation from leaving it. Many people think the average planetary temperatures may rise by 4°C or so by 2050. This is probably true since Antarctic ice cores evidence indicates that, over the last 160000 years, ice ages coincided with reduced levels of carbon dioxide and warmer interglacial episodes with increased levels of the gas in the atmosphere. Consequently, such an elevation of temperature over such a relatively short span of time would have catastrophic results in terms of rising sea level and associated flooding of vast tracts of low-lying lands. Reducing the burning of fossil fuels makes sense on both economic and environmental grounds. One of the most attractive alternatives is geothermal resources, especially in developing countries, for instance in El Salvador where geothermal energy provides about a fifth of total installed electrical power already. In fact, by the middle 1980s, at least 121 geothermal power plants were operating worldwide, most being of the dry steam type.

Available in PDF, EPUB and Kindle. Book excerpt: The Guiana Shield is an area of special importance, especially to those concerned with Precambrian geology because it provides a perspective on a part of Earth history not well represented elsewhere. For economic geologists, its mineral resource potential is just beginning to be understood. This overview of current knowledge will greatly help geologists already working in the area, draw attention to the need for mineral exploration research, and encourage the inclusion of the Shield in future Precambrian studies.

Download or read book Soil and Sediment Remediation written by Piet Lens and published by IWA Publishing. This book was released on 2005-09-30 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.
