Introduction to Applied Geophysics covers the fundamental methods of exploration geophysics in a depth and style both challenging and appropriate to undergraduates. Because of the increasing opportunities for students to conduct field experiments, the authors focus on methods, examples, illustrations, applications, and problem sets that emphasize shallow exploration of the Earth's surface. The textbook includes chapters on refraction seismology, electrical resistivity methods, gravity, magnetic surveying, and electromagnetic methods, including ground conductivity measurements and ground-penetrating radar. Geologic, engineering, and environmental applications are emphasized throughout. For each geophysical method, the theory and its application in exploring a given target in introduced. Each chapter includes a brief discussion of the applicable instruments, field operations, data collection and reduction, and limitations on interpretation. The textbook is supported by an extensive package of software. This edition from Cambridge University Press is a re-issue of the WW Norton edition, first published in 2006.
