Active geophysical monitoring is an important new method for studying time-evolving structures and states in the tectonically active Earth's lithosphere. It is based on repeated time-lapse observations and interpretation of rock-induced changes in geophysical fields periodically excited by controlled sources. In this book, the results of strategic systematic development and the application of new technologies for active geophysical monitoring are presented. The authors demonstrate that active monitoring may drastically change solid Earth geophysics, through the acquisition of substantially new information, based on high accuracy and real-time observations. Active monitoring also provides new means for disaster mitigation, in conjunction with substantial international and interdisciplinary cooperation.

The scientific disciplines of hydrology and hydrogeology are expanding as the Earth's water is being recognized by governments and individuals as a shrinking resource-no entity can afford to take water for granted. At the present time, there is no single reference source for definitions. The Encyclopedic Dictionary of Hydrogeology is a practical, comprehensive reference guide with complete definitions of terms in hydrogeology and other fields closely related to water practices. This concise reference not only defines terms and concepts, but also provides a clear explanation of key elements so that an in-depth understanding of processes may be obtained.
* With more than 2,000 entries, from "absolute permeability" to the "Z-R relationship," this dictionary features the most up-to-date vocabulary in hydrology and hydrogeology. This dictionary would be of use to practicing scientists and professionals in all the fields of water science.
* More than 340 graphs, tables and diagrams complement the entries in order to clarify terms, methods, or processes
* Essential reference for students, academics, consultants, and practitioners in hydrology, hydrogeology, environmental engineering, environmental law, and the government

This book is intended to be the most complete and up-to-date guide to the geology and fossils of the New Forest, providing a wealth of information of interest to both the amateur fossil collector and the professional geologist. It includes some 200 field photographs, palaeogeographic maps, digitised borehole/outcrop logs, and geological cross sections. Also included is a tour of the regional geological evolution of southern England since the Permian Period (-280 million years ago), based on deep boreholes and coastal exposures, including the world-famous Jurassic coast of Dorset and east Devon. The author discusses the petroleum geology of southern England and the New Forest and gives a detailed overview of the stratigraphy of the Hampshire Basin, followed by related aspects of economic geology within this area, including ironstones, freshwater aquifers, geothermal energy, sand, clay and peat resources. Finally, there is an up-to-date and complete account of the principal fossil localities, together with a comprehensive gallery of photographs with accompanying descriptions of the most abundant fossils within the New Forest National Park.

The book requires only rudimentary physics knowledge but ability to program computers creatively and to keep the mind open to simple and not so simple models, based in individuals, for the living world around us.
* Interdisciplinary coverage
* Research oriented
* Contains and explains programs
* Based on recent discoveries
* Little special knowledge required besides programming
* Suitable for undergraduate and graduate research projects

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 138.Subduction zones helped nucleate and grow the continents, they fertilize and lubricate the earth's interior, they are the site of most subaerial volcanism and many major earthquakes, and they yield a large fraction of the earth's precious metals. They are obvious targets for study--almost anything you learn is likely to impact important problems--yet arriving at a general understanding is notoriously difficult: Each subduction zone is distinct, differing in some important aspect from other subduction zones; fundamental aspects of their mechanics and igneous processes differ from those in other, relatively well-understood parts of the earth; and there are few direct samples of some of their most important metamorphic and metasomatic processes. As a result, even first-order features of subduction zones have generated conflict and apparent paradox. A central question about convergent margins, for instance--how vigorous magmatism can occur where plates sink and the mantle cools--has a host of mutually inconsistent answers: Early suggestions that magmatism resulted from melting subducted crust have been emphatically disproved and recently just as emphatically revived; the idea that melting is fluxed by fluid released from subducted crust is widely held but cannot explain the temperatures and volatile contents of many arc magmas; generations of kinematic and dynamic models have told us the mantle sinks at convergent margins, yet strong evidence suggests that melting there is often driven by upwelling. In contrast, our understanding ofwhy volcanoes appear at ocean ridges and "hotspots"--although still presenting their own chestnuts--are fundamentally solved problems.
