Just a few meters below the Earth's surface lie features of great importance, from geological faults which can produce devastating earthquakes, to lost archaeological treasures! This refreshing, up-to-date book explores the foundations of interpretation theory and the latest developments in near-surface techniques, used to complement traditional geophysical methods for deep-exploration targets. Clear but rigorous, Near-Surface Applied Geophysics explains theory and practice in simple physical terms, supported by intermediate-level mathematics. Techniques covered include magnetics, resistivity, seismic reflection and refraction, surface waves, induced polarization, self-potential, electromagnetic induction, ground-penetrating radar, magnetic resonance, interferometry, seismoelectric and more. Sections on data analysis and inverse theory are provided and chapters are illustrated by case studies, giving students and professionals the tools to plan, conduct and analyze a near-surface geophysical survey. This is an important textbook for advanced-undergraduate and graduate students in geophysics and a valuable reference for practising geophysicists, geologists, hydrologists, archaeologists, and civil and geotechnical engineers.
"This book provides an excellent introduction to the rapidly emerging field of near-surface geophysics. The state-of-the-art material covered in the text will not only be helpful for undergraduate and graduate students, but it will also serve as a valuable reference for practitioners."
- Hansruedi Maurer, ETH Zürich
"A great book for teaching undergraduates the essence of all geophysical techniques used in near surface exploration; the mix of theory, practice and case studies is just right for students."
- Graham Heinson, University of Adelaide
"This is an excellent text for advanced geophysics undergraduate and graduate students, a valuable resource for scientists and engineers involved in characterizing the earth's near surface, and the material fills a void in the bookshelves of many geoscientists."
- Doug Oldenburg, University of British Columbia
