(I) This is an introductory study of gravity and magnetic methods for imaging the earth's subsurface. The course begins with the connection between geophysical measurements and subsurface materials. It introduces basic concepts, mathematics, and physics of gravity and magnetic fields, emphasizing similarities with the equations and physics that underlie all geophysical methods. These methods are employed in geotechnical and environmental engineering and resources exploration for base and precious metals, industrial minerals, geothermal and hydrocarbons. The discussion of each method includes the principles, instrumentation, and procedures of data acquisition, analysis, and interpretation. Prerequisites: PHGN200, MATH213, MATH225, and concurrent enrollment in MATH348 or PHGN311. 2 hours lecture, 3 hours lab; 3 semester hours.
