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.
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)
This 1998 book documents the collection, processing and analysis of satellite magnetic field data.
An introductory guide to global magnetic field properties, Earth Magnetism addresses, in non-technical prose, many of the frequently asked questions about Earth's magnetic field. Magnetism surrounds and penetrates our Earth in ways basic science courses can rarely address. It affects navigation, communication, and even the growth of crystals. As we observe and experience an 11-year solar maximum, we may witness spectacular satellite-destroying solar storms as they interact with our magnetic field. Written by an acknowledged expert in the field, this book will enrich courses in earth science, atmospheric science, geology, meteorology, geomagnetism, and geophysics. Contains nearly 200 original illustrations and eight pages of full-color plates. * Largely mathematics-free and with a wide breadth of material suitable for general readers * Integrates material from geomagnetism, paleomagnetism, and solar-terrestrial space physics. * Features nearly 200 original illustrations and 4 pages of colour plates
The Earth's Magnetic Field : Its History, Origin, and Planetary Perspective
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.
All geologists need a broad understanding of science to understand the processes they study and analytical techniques. In particular, geology students need to grasp the basic physics behind these processes, which this book provides in plain language and simple mathematics. It gives the reader information that will enable him to ascertain the validity of what he reads in scientific literature. Water, an essential component of geology, is emphasized, and many published errors on water are discernible when armed with this text. This updated edition discusses a wide range of topics, including electromagnetic radiation from optics to gamma rays, atomic structure and age-dating, heat and heat flow, electricity and magnetism, stress and strain, sea waves, acoustics, and fluids and fluid flow. The book gives basic definitions and dimensions and also some warnings about misunderstanding mathematical statistics, particularly of linear regression analysis, and unenlightened computation.
