Theoretical Developments in Electromagnetic Induction Geophysics with Selected Applications in the Near Surface

  • Mark E. Everett


Near-surface applied electromagnetic geophysics is experiencing an explosive period of growth with many innovative techniques and applications presently emergent and others certain to be forthcoming. An attempt is made here to bring together and describe some of the most notable advances. This is a difficult task since papers describing electromagnetic induction methods are widely dispersed throughout the scientific literature. The traditional topics discussed herein include modeling, inversion, heterogeneity, anisotropy, target recognition, logging, and airborne electromagnetics (EM). Several new or emerging techniques are introduced including landmine detection, biogeophysics, interferometry, shallow-water electromagnetics, radiomagnetotellurics, and airborne unexploded ordnance (UXO) discrimination. Representative case histories that illustrate the range of exciting new geoscience that has been enabled by the developing techniques are presented from important application areas such as hydrogeology, contamination, UXO and landmines, soils and agriculture, archeology, and hazards and climate.


Controlled-source electromagnetics Electrical conductivity Near-surface geophysics 



I thank the EM Induction Workshop committee for the opportunity to present this review. I am also grateful to Sofia Davydycheva and Richard Smith, respectively, for bringing to my attention some important logging and airborne electromagnetics papers. This paper was written while I was on sabbatical leave from Texas A&M as a visiting professor at ETH, Zurich.
