Download or read book Earth Magnetism written by Wallace H. Campbell and published by Academic Press. This book was released on 2001-01-19 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Book excerpt: This survey summarizes what is known about the magnetic field of the earth, based on information available through 1971. Observed phenomena are described and interpreted in terms of the most widely accepted physical explanations. An overview of the geomagnetic field and its dynamic relationship with its terrestrial and interplanetary environment is first presented as briefly as possible, followed by more detailed descriptions of geomagnetic measurements and experimental methods, precise current models and past behavior of the main field, regular variations in the field resulting from the motion of the earth, disturbance variations of the field produced by interplanetary environment, and dynamic processes occurring in the outer magnetosphere. Extensive references is a replacement for Chapter 11 of Handbook of Geophysics and Space Environment (Shea L. Valley, ed.), Air Force Cambridge Research Laboratories and McGraw-Hill Book Co., New York, 1965.

Download or read book Geomagnetic Field Variations in the Past written by E. Tema and published by Geological Society of London. This book was released on 2020-10-15 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decades, palaeomagnetic research has provided important information about the past variation of the Earth’s magnetic field (EMF) from its origin to the present day. However, questions regarding the origin and evolution of the EMF as well as the frequency and spatial distribution of its variations still remain open to debate. This Special Publication provides new insights into the study of the temporal and spatial evolution of the EMF presenting new data from palaeomagnetic and rock magnetic studies of archaeological materials, sediments and lavas. The papers presented cover a wide range of topics related to archaeology, stratigraphy and climate, including new data from several parts of the world, such as Europe, Africa, Australia, New Zealand, India and the Baltic Sea. This Special Publication aims to present an overview of the most recent secular variation studies and their use to disclose fundamental properties of the EMF evolution.

Book excerpt: 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'.

Uittreksel: Het aardmagnetisch veld (ook wel aardmagneetveld genoemd) is het magnetisch veld dat de Aarde omringt. Het aardmagnetisch veld, dat vermoedelijk ontstaan is door stroming van magnetische mineralen en elementen in de aardkern, beschermt de planeet tegen de geioniseerde straling van de zonnewind. De invloedzone van het aardmagnetisch veld in de ruimte, die vele duizenden kilometers ver in de ruimte reikt, wordt de magnetosfeer genoemd. Het aardmagnetisch veld wordt verder van de Aarde af steeds zwakker. In het zonnestelsel hebben behalve de Aarde alleen de planeten Jupiter, Saturnus, Uranus...

The book describes in fine detail the current state of knowledge and provides an up-to-date synthesis of the most basic concepts. It is an indispensable working tool not only for geophysicists and geophysics students but also for geologists, physicists, atmospheric and environmental scientists, and engineers.

Download or read book An Analysis of the Earth s Magnetic Field from 1835 to 1965 written by Keith L. McDonald and published by . This book was released on 1967 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is an analysis and description of the earth's magnetic field based on observed data from the time of Gauss to the most recent epochs. An attempt was made to collect all Gauss-Schmidt coefficients of previous investigators and extensive computations were made using selections of these data. Root-mean-square representations of geomagnetic field elements are employed to depict time trends and structural dissymetries at the earth's surface and core-mantle boundary. Our analysis establishes that the magnetic dipole field is being driven destructively to smaller values by fluid motions which transform its magnetic energy into near neighboring modes rather than expend it more directly as joule heat. Concurrent with the continual decrease in field energy in the atmosphere, since 1900 at least, sixth-degree analyses indicate that the mean magnetic-energy density in the outermost layers of the core fluid has been increasing. An associated phenomenon is the continued increase in hemispheric dissymetry, the Southern Hemisphere preponderating. Defining an asymmetry ratio, our analysis infers by extrapolation that the geomagnetic field was sensibly symmetric in the year 1670 A.D. The average rate of westward drift of the geomagnetic pole during the past 130 years is 0.042 degree/year in azimuth angle, corresponding to a polar rotation period of 8.6 thousand years. The motion appears, however, to have slowed somewhat since about 1900. The polar angle shows no progressive motions.

This book was released on 2003-02-14 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: The German research satellite CHAMP had been launched in summer 2000. Its modern instruments and near Earth orbit allow for the first time to collect data of the gravitational and magnetic fields and in addition to sound out the atmosphere and ionosphere by using GPS techniques. The book is the result of the first meeting of the international CHAMP research groups gathering 18 months later at the GeoForschungsZentrum Potsdam. Besides technical information the volume offers a comprehensive overview over the use of CHAMP data for Earth System Research in the fields of Geodesy, Geophysics and Meteorology.

Available in PDF, EPUB and Kindle. Book excerpt: 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

This book was released on 1995-01-27 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book bridges the gap between the classic texts on potential theory and modern books on applied geophysics. Introductory chapters discuss potential theory with emphasis on those aspects particularly important to earth scientists, such as Laplace's equation, Newtonian potential, magnetic and electrostatic fields, conduction of heat, and spherical harmonic analysis. Later chapters apply these theoretical concepts specifically to the interpretation of gravity and magnetic anomalies, with emphasis on anomalies caused by crustal and lithospheric sources. The book is ideal for graduate students and researchers in applied geophysics.
