May 2012 – New Book Published by Prof. Alan G. Jones, School of Cosmic Physics
The Magnetotelluric Method: Theory and Practice was published this month by Cambridge University Press. It was co-written and co-edited by Professor Alan G. Jones (Geophysics Section, School of Cosmic Physics). 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. It is increasingly used in geological applications and the petroleum industry. 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 one-, two- and three-dimensional 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 the magnetotelluric method for academic researchers and advanced students, and will be of interest to industrial practitioners and geoscientists wanting to incorporate rock conductivity into their interpretations.
