Foundations in Geophysical Electromagnetic Theory and Methods is a new edition that builds on the strength of the original book related to systematic exposition of all types of geophysical electromagnetic methods. Over the last decade, significant progress has been made in electromagnetic geophysics, and this new edition includes material that reflects that progress with a special focus on recent advances in marine and airborne electromagnetic methods. Also included is a new chapter that presents recent case histories on practical applications in tectonic studies, mineral exploration, environmental studies, and off-shore hydrocarbon exploration. Presenting state-of-the-art geophysical electromagnetic theory and methods, Foundations in Geophysical Electromagnetic Theory and Methods will be of interest to geoscientists working in all areas of geophysics, including physics of the solid earth, exploration geophysics, and general areas of applied physics and geophysics. It will also appeal to graduate students and researchers working in the field of electromagnetic geophysics. Presents theoretical and methodological findings, as well as applications of recently developed algorithms and software in solving practical problems Describes the practical importance of electromagnetic databy enabling discussions on construction of a closed technological cycle, processing, analysis, and three-dimensional interpretation Features current findings in the field, especially with magneto-variational and seismo-electrical methods and the practice of 3D interpretations.
