Environmental Magnetism


Book Description

Magnetism is important in environmental studies for several reasons, the two most fundamental being that most substances exhibit some form of magnetic behavior, and that iron is one of the most common elements in the Earth's crust. Once sequestered in a suitable material, magnetic particles constitute a natural archive of conditions existing in former times. Magnetism provides a tracer of paleo-climatic and paleo-environmental conditions and processes.Environmental Magnetism details the occurrence and uses of magnetic materials in the natural environment. The first half of the volume describes the basic principles. The second half discusses the applications of magnetic measurements in various environmental settings on land, in lakes, in the ocean, and even various biological organisms.* Material is broadly applicable to environmental studies* Case histories illustrate key points* Extensive bibliography makes further research quick and easy




Environmental Magnetism


Book Description

The scientist will be forced, in the unenthusiastic words of one of my scientific colleagues, 'to slosh about in the primordial ooze known as inter-disciplinary studies'. John Passmore Man's responsibility for nature The present text has arisen from some thirteen years advances in our perception, appraisal and creative use of collaboration between the two authors. During that of order in natural systems. Out of this can come period, upwards of a dozen postgraduates in enhanced insight into processes, structures and Edinburgh, the New University of Ulster and Liver systems interactions on all temporal and spatial scales pool have been closely involved in exploring many of and at all integrative levels from subatomic to cosmic. the applications of magnetic measurements described In the environment, elements of order are often in the second half of the book.

Soil Magnetism


Book Description

Soil Magnetism: Applications in Pedology, Environmental Science and Agriculture provides a systematic, comparative, and detailed overview of the magnetic characterization of the major soil units and the observed general relationships, possibilities, and perspectives in application of rock magnetic methods in soil science, agriculture, and beyond. Part I covers detailed magnetic and geochemical characterization of major soil types according to the FAO classification system, with Part II covering the mapping of topsoil magnetic signatures on the basis of soil magnetic characteristics. The book concludes with practical examples on the application of magnetic methods in environmental science, agriculture, soil pollution, and paleoclimate. - Provides an overview of the major findings of uncontaminated soil profiles and proposes a system of magnetic characteristics - Elucidates the relationship between geochemical and magnetic characteristics of different soil types, providing a basis for wider recognition and application of soil magnetism in classical pedagogical characterization of soils - Covers the peculiarities of the main taxonomic soil groups in terms of magnetic mineralogy and depth variations in concentration, grain size, and phase composition of iron oxides




The Earth's Magnetism


Book Description

Initially, this book reviews the general characteristics of the Earth’s magnetic field and the magnetic properties of minerals, and then proceeds to introduce the multifold applications of geomagnetism in earth sciences. The authors analyze the contribution of geomagnetism both in more general geological fields, such as tectonics and geodynamics, and in applied ones, such as prospecting and pollution. Primarily, the book is aimed at undergraduate geology or geophysics students. It is geared to provide them with a general overview of geomagnetism, allowing them to understand what contributions this branch of science can offer in the more special sectors of earth sciences. Graduate students and geology researchers will also benefit from it, as it enables them to gain a clear and concise image of the techniques which can be applied in their areas of specialization.







Recent Advances in Rock Magnetism, Environmental Magnetism and Paleomagnetism


Book Description

This book offers a collection of papers presented in the International Conference on Geomagnetism, Paleomagnetism and Rock Magnetism held in Kazan (Russia) in October 2017. Papers in this book are dedicated to the study of the geomagnetic field through most of the Earth's history as well as planetary and meteorite magnetism, and magnetic signatures of terrestrial impact craters. Recent studies, summaries, and reviews include: 1 - theory of the geomagnetic field, its generation and variations; 2 - experimental data on the geomagnetic field changes; 3 – studies of rock magnetism; 4 – paleotectonic reconstructions and paleoceanography; 5 – magnetostratigraphy; 6 – extraterrestrial magnetism. Summary reports and reviews will be presented by the world’s leading experts in the field of geomagnetic studies. Such workshops held by Academic Council have become traditional. They are always attended by leading professionals from Russia, CIS and non-CIS countries. In addition to discussion sessions focused on recent studies and findings, lectures on some basic concepts of geomagnetism will be delivered by leading Russian and foreign scientists




Quaternary Climates, Environments and Magnetism


Book Description

The Quaternary has been a period of major climatic and environmental oscillations, and our knowledge of these past variations is important for our understanding of the possible impact of human activity on the present-day environment. Quaternary Climates, Environments and Magnetism presents an up-to-date account of the rich variety of uses of magnetic measurements in the environmental geosciences. Ten chapters by leading world authorities describe the highlights of environmental magnetic work during the past decade and identify directions for future research. This comprehensive and multidisciplinary coverage leads to a more thorough understanding of the environmental processes involved. This volume will be of interest to research scientists from a wide range of disciplines working on Quaternary environments, including earth and environmental sciences, physical geology, geography, and palaeoclimatology. It will also be valuable as a supplementary text for graduates and advanced undergraduates.




Essentials of Paleomagnetism


Book Description

"This book by Lisa Tauxe and others is a marvelous tool for education and research in Paleomagnetism. Many students in the U.S. and around the world will welcome this publication, which was previously only available via the Internet. Professor Tauxe has performed a service for teaching and research that is utterly unique."—Neil D. Opdyke, University of Florida




Our Magnetic Earth


Book Description

For the general public, magnetism often seems more the province of new age quacks, movie mad scientists, and grade-school teachers than an area of actual, ongoing scientific inquiry. But as Ronald T. Merrill reveals in Our Magnetic Earth, geomagnetism really is an enduring, vibrant area of science, one that offers answers to some of the biggest questions about our planet’s past—and maybe even its future. In a clear and careful fashion, he lays out the physics of geomagnetism and magnetic fields, then goes on to explain how Earth’s magnetic field provides crucial evidence for our understanding of continental drift and plate tectonics; how and why animals, ranging from bacteria to mammals, sense and use the magnetic field; how changes in climate over eons can be studied through variations in the magnetic field in rocks; and much more. Throughout, Merrill peppers his scientific account with bizarre anecdotes and fascinating details, from levitating pizzas to Moon missions to blackmailing KGB agents—a reminder that real science can at times be stranger, and more amusing, than fiction. A winning primer for anyone who has ever struggled with a compass or admired a ragged V of migrating geese, Our Magnetic Earth demonstrates that education and entertainment need not be polar opposites.
