Theory and practice of seismic refraction, gravity, electromagnetic, and resistivity surveys will be presented. Lectures will cover both geophysical theory and field method procedures, accompanied by either a geophysical field exercise or data processing lab. The final grade is based on homework grades, a project report and the related presentation. Field projects cover applications in environmental engineering, exploration, and earthquake hazards. Instruments to be used include the 64-node Syscal multi-node resisitvity system, the Geonics EM-34 frequency domain loop antennae system, the Geonics microgravimeter, and the Geometrics 624-channel seismic recording system. Commercial codes will be used for processing the data.
