Introduction and General Points --Machine generated contents note:

Everyday Applied Geophysics 1 covers the physical methods permitting the environmental exploration of the sub-surface in 1, 2, 3 or 4 dimensions (the last is for time-lapse in terms of physical environmental state and geometry). The ground is transparent to electrical currents, electromagnetic induction, magnetic fields and seismic (acoustic) waves. All extend our senses by using the propagation of these phenomena through underground materials. The book specifically addresses the methods feasible, accessible and affordable to all users, and provides simple apparatus electronic diagrams. The book also features open-source and free software links for data interpretation. Covers physical methods permitting the environmental exploration of the sub-surface in 1, 2, 3 or 4 dimensionsAddresses the methods feasible, accessible and affordable to all usersProvides simple apparatus electronic diagrams, as well as open-source and free software links for data interpretation.
