The third edition expands the theoretical and practical treatment of magnetotelluric and airborne electromagnetic methods, with particular emphasis on MT transfer functions, inversion methodologies, and natural-source airborne EM systems. Of special relevance to MobileMT is the discussion of modern airborne natural-field EM technologies that combine airborne magnetic measurements with ground-based magnetotelluric reference stations to achieve high-resolution, deep-penetration resistivity imaging without artificial transmitters.
