Book Description
The magnetotelluric method is a technique for imaging the electrical conductivity and structure of the Earth, from the near surface down to the 410 km transition zone and beyond. This book forms the first comprehensive overview of magnetotellurics, from the salient physics and its mathematical representation to practical implementation in the field, data processing, modeling and geological interpretation. Electromagnetic induction in 1-D, 2-D and 3-D media is explored, building from first principles, and with thorough coverage of the practical techniques of time series processing, distortion, numerical modeling and inversion. The fundamental principles are illustrated with a series of case histories describing geological applications. Technical issues, instrumentation and field practices are described for both land and marine surveys. This book provides a rigorous introduction to magnetotellurics for academic researchers and advanced students, and will be of interest to industrial practitioners and geoscientists wanting to incorporate rock conductivity into their interpretations.

Pages : 108
Book Description
The process of finding one-dimensional Cagniard models to fit experimental magnetotelluric data in a least squares sense is investigated. A modification to the Newton-Raphson method for non-linear regression is developed. This method together with the gradient method is applied to data generated from exact models and is shown to be successful, provided certain conditions on the significance of the model parameters are met. A finite difference scheme for two-dimensional models is developed. The model is restricted to be a layered model in which one of the layers possesses a lateral inhomogeneity. Boundary conditions are applied in such a way as to allow eigenfunction expansions to be written in the homogeneous layers. This in turn allows proper boundary conditions to be applied at the air-earth interface and at infinity. For the scheme which is used, the finite difference equations are written only in the anomalous layer and are solved using a direct method. Results are presented for both the transverse electric and transverse magnetic polarizations for a typical model. The impedances generated from this model are used as experimental data to demonstrate the effect of fitting data generated from a two-dimensional earth with one-dimensional models. (Author).

ISBN: 3540778144
Category : Science
Languages : en
Pages : 576
Book Description
Magnetotellurics is finding increasing applications for imaging electrically conductive structures below the Earth`s surface - in both industrial and academic research projects. In this book the authors provide a systematic approach to understanding the modern theory of ill-posed problems which is essential to making confident meaningful interpretations of magnetotelluric and magnetovariational soundings. The interpretation is conducted in an interactive way.

Geomagnetically Induced Currents from the Sun to the Power Grid
Author: Jennifer L. Gannon
Publisher: John Wiley & Sons
ISBN: 1119434386
Category : Science
Languages : en
Pages : 410
Book Description
An introduction to geomagnetic storms and the hazards they pose at the Earth’s surface Geomagnetic storms are a type of space weather event that can create Geomagnetically Induced Currents (GICs) which, once they reach Earth’s surface, can interfere with power grids and transport infrastructure. Understanding the characteristics and impacts of GICs requires scientific insights from solar physics, magnetospheric physics, aeronomy, and ionospheric physics, as well as geophysics and power engineering. Geomagnetically Induced Currents from the Sun to the Power Grid is a practical introduction for researchers and practitioners that provides tools and techniques from across these disciplines. Volume highlights include: Analysis of causes of geomagnetic storms that create GICs Data and methods used to analyze and forecast GIC hazard GIC impacts on the infrastructure of the bulk power system Analysis techniques used in different areas of GIC research New methods to validate and predict GICs in transmission systems
