View: 1755

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.

Looking into the Earth

An Introduction to Geological Geophysics

Author: Alan E. Mussett,M. Aftab Khan

Publisher: Cambridge University Press

ISBN: 1139643649

Category: Science

Page: N.A

View: 6435

Looking Into the Earth comprehensively describes the principles and applications of both 'global' and 'exploration' geophysics on all scales. It forms an introduction to geophysics suitable for those who do not necessarily intend to become professional geophysicists, including geologists, civil engineers, environmental scientists, and field archaeologists. The book is organised into two parts: Part 1 describes the geophysical methods, while Part 2 illustrates their use in a number of extended case histories. Mathematical and physical principles are introduced at an elementary level, and then developed as necessary. Student questions and exercises are included at the end of each chapter. The book is aimed primarily at introductory and intermediate university students taking courses in geology, earth science, environmental science, and engineering. It will also form an excellent introductory textbook in geophysics departments, and will help practising geologists, archaeologists and engineers understand what geophysics can offer their work.

This “fantastic story” of one of physics’ great riddles takes us through centuries of scientific history (Simon Lamb, author of Devil in the Mountain). Why do compass needles point north—but not quite north? What guides the migration of birds, whales, and fish across the world’s oceans? How is Earth able to sustain life under an onslaught of solar wind and cosmic radiation? For centuries, the world’s great scientists have grappled with these questions, all rooted in the same phenomenon: Earth’s magnetism. Over two thousand years after the invention of the compass, Einstein called the source of Earth’s magnetic field one of greatest unsolved mysteries of physics. Here, for the first time, is the complete history of the quest to understand the planet’s attractive pull—from the ancient Greeks’ fascination with lodestone to the geological discovery that the North Pole has not always been in the North—and to the astonishing modern conclusions that finally revealed the true source. Richly illustrated and skillfully told, North Pole, South Pole unfolds the human story behind the science: that of the inquisitive, persevering, and often dissenting thinkers who unlocked the secrets at our planet’s core. “In recent years, many very good books for interested non-scientists have been published: Richard Dawkins’s Climbing Mount Improbable and The Ancestor’s Tale, Stephen Jay Gould’s The Lying Stones of Marrakech, and Dava Sobel’s Longitude and The Planets, to name some of them. North Pole, South Pole . . . is a worthy addition to that list . . . Turner has a great story to tell, and she tells it well.” —The Press (New Zealand)

The Spinning Magnet

The Electromagnetic Force That Created the Modern World--and Could Destroy It

Author: Alanna Mitchell

Publisher: Penguin

ISBN: 1101985186

Category: Science

Page: 336

View: 6299

An engrossing history of the science of one of the four fundamental physical forces in the universe, electromagnetism, right up to the latest indications that the poles are soon to reverse and destroy the world's power grids and electronic communications A cataclysmic planetary phenomenon is gathering force deep within the Earth. The magnetic North Pole will eventually trade places with the South Pole. Satellite evidence suggests to some scientists that the move has already begun, but most still think it won't happen for many decades. All agree that it has happened many times before and will happen again. But this time it will be different. It will be a very bad day for modern civilization. Award-winning science journalist Alanna Mitchell's delightful storytelling introduces enchanting characters from investigations into magnetism in thirteenth-century France to the discovery in the Victorian era that electricity and magnetism emerge from the same force. No one has ever told so eloquently how the Earth itself came to be seen as a magnet, spinning in space with two poles, and that those poles dramatically, catastrophically reverse now and then... The recent finding that Earth's magnetic force field is decaying faster than previously thought, raising fears of an imminent pole reversal, ultimately gives The Spinning Magnet a spine-tingling urgency. When the poles switch, a process that takes many years, Earth is unprotected from solar radiation storms that would, among other things, wipe out all electromagnetic technology. No satellites, no Internet, no smartphones--maybe no power grid at all. Alanna Mitchell offers a beautifully crafted narrative history of ideas and science that readers of Stephen Greenblatt and Sam Kean will love.

The Magnetic Field of the Earth

Paleomagnetism, the Core, and the Deep Mantle

Topics involved in studies of the Earth's magnetic field and its secular variation range from the intricate observations of geomagnetism, to worldwide studies of archeomagnetism and paleomagnetism, through to the complex mathematics of dynamo theory. Traditionally these different aspects of geomagnetism have been studied and presented in isolation from each other. The Magnetic Field of the Earth draws together these major lines of inquiry into an integrated framework to highlight the interrelationships and thus to provide a more comprehensive understanding of the geomagnetic field. The text is organized so that paleomagnetists and dynamo theoreticians may both benefit from the results and arguments presented by the other. A particular example is the presentation of paleomagnetic results to illuminate the observational constraints on geodynamo theory. Conversely, dynamo theory is explained in such a way that paleomagnetists may utilize it to present their data more effectively. Other important features of the book include a discussion of planetary magnetic fields and their implications for dynamo theory and the most recent set of magnetic charts. This unique integrated approach to the subject will make The Magnetic Field of the Earth an invaluable reference book for all geophysicists, particularly those wishing to gain insight into alternative branches of research. * The only book to integrate material from geomagnetism, paleomagnetism, and dynamo theory * Spans a breadth of material greater than any other textbook published in the past 50 years * Covers introductory material and complex concepts, making it useful to students as well as to researchers in the field *Explains the basics of each topic in a comprehensive manner * Reviews state-of-the-art knowledge in each area * Discusses the development and analysis of geomagnetic reversal sequences in detail

Environmental Magnetism

Principles and Applications of Enviromagnetics

Author: Michael Edwin Evans,Friedrich Heller

Publisher: Academic Press

ISBN: 9780122438516

Category: Science

Page: 299

View: 3681

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

What is the real role of carbon dioxide in the atmosphere? Why is the climate no warmer now that it was a thousand years ago, when the level of carbon dioxide has nearly doubled? Why do we have deserts? Why was there an ice age? Why is the planet so cold now, compared to the way it was in the distant past? These are just some of the questions the author seeks to answer, by looking not just at the geological evidence, but at the way the atmosphere of the earth works now. The book brings the reader right up to date with the latest developments in geology. It deals with the geological history of rocks, landforms and vulcanicity. The main emphasis is on the geology of the USA. Examples include the Grand Canyon, Yellowstone, Bryce Canyon, Yosemite and Hawaii. There is also a chapter on the formation of the Rocky Mountains. The book should be of special interest to those who already know some geology, such a Geography graduates. This edition is illustrated with 80 photographs, maps and diagrams.

This book is unique in bridging the gap between geology and geophysics. Its integrative approach presents students and researchers in these disciplines with other methodologies as they try to understand the Earth's processes. It runs the gamut of earth sciences, from earthquakes and seismic exploration to thermal convection and the orogenic processes. Each chapter starts with the well-established facts and then proceeds through a logical framework to the most conjectural questions, such as continental drift in Paleozoicc and Precambrian times or mantle convection. Many of the issues discussed here do not yet have unanimously agreed solutions, but the extensive references point the reader to further possibilities.
