Equatorial Electrojet


Book Description

This is the first book to review all the fields of equatorial electrojet phenomena and their relevant theories in one volume. In certain relevant sections, the book discusses both the equatorial electrojet and the world-wide parts of the Sq current systems. Onwumwchili is an internationally known and highly respected expert in the equatorial electrojet field- a brand of geomagnetism.

The Magnetotelluric Method


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.

Encyclopedia of Solid Earth Geophysics


Book Description

The past few decades have witnessed the growth of the Earth Sciences in the pursuit of knowledge and understanding of the planet that we live on. This development addresses the challenging endeavor to enrich human lives with the bounties of Nature as well as to preserve the planet for the generations to come. Solid Earth Geophysics aspires to define and quantify the internal structure and processes of the Earth in terms of the principles of physics and forms the intrinsic framework, which other allied disciplines utilize for more specific investigations. The first edition of the Encyclopedia of Solid Earth Geophysics was published in 1989 by Van Nostrand Reinhold publishing company. More than two decades later, this new volume, edited by Prof. Harsh K. Gupta, represents a thoroughly revised and expanded reference work. It brings together more than 200 articles covering established and new concepts of Geophysics across the various sub-disciplines such as Gravity, Geodesy, Geomagnetism, Seismology, Seismics, Deep Earth Processes, Plate Tectonics, Thermal Domains, Computational Methods, etc. in a systematic and consistent format and standard. It is an authoritative and current reference source with extraordinary width of scope. It draws its unique strength from the expert contributions of editors and authors across the globe. It is designed to serve as a valuable and cherished source of information for current and future generations of professionals.




Ionospheric Sporadic


Book Description

International Series of Monographs on Electromagnetic Waves: Ionospheric Sporadic E focuses on the methodologies, approaches, reactions, and calculations involved in the study of the ionospheric sporadic E. The selection first offers information on the occurrence of sporadic E and reflection mechanisms for sporadic E, as well as geographic occurrence and temporal variations of sporadic E and thin and scattering models. The text then examines the final remarks of the 1957 AGARD conference of sporadic-E ionization and study of radio wave scattering from sporadic E near the magnetic equator. The publication takes a look at sporadic E as observed with rockets and backscatter observations of sporadic E. Discussions focus on gradients, height preference, gradients in electron density, time variation, and interpretation and observation limitations. The text then ponders on lunar tidal variations of sporadic E and theoretical study of sporadic-E structure in the light of radio measurements. The selection is a vital reference for readers interested in the in the study of the ionospheric sporadic E.
