Gravity and Magnetic Exploration

William J. Hinze is Emeritus Professor of Geophysics at Purdue University and has taught exploration geophysics for 40 years. His extensive teaching and research experience is complemented by industrial consulting experience in the geological and engineering applications of gravity and magnetic fields. He has authored or co-authored more than 130 journal publications and four books, and has served as Associate Editor of Geophysics and Senior Editor of The Journal of Geophysical Research – Solid Earth. Professor Hinze has been a member of numerous government and scientific panels dealing with key issues from the geophysics and geology of continents to nuclear waste disposal and geophysical data. He is a member of the Society of Exploration Geophysicists, the American Geophysical Union and the Geological Society of America. Ralph R. B. von Frese is Professor of Earth Sciences at Ohio State University, where he has taught undergraduate and graduate courses across geophysics and Earth systems since 1982. His research has focused mostly on archaeological and planetary applications of gravity and magnetic fields and he has authored or co-authored more than 100 journal publications and served on several government and scientific panels. Professor von Frese is the founding co-chair of the Antarctic Digital Magnetic Anomaly Project (ADMAP), an international collaboration of the Scientific Committee for Antarctic Research (SCAR) and the International Association of Geomagnetism and Aeronomy (IAGA). He is a member of the Society of Exploration Geophysicists, the American Geophysical Union, the Geological Society of America and the International Association for Mathematical Geology. Afif H. Saad is a geophysical consultant to the oil and gas exploration industry, specializing in integrated interpretation, modeling, magnetic depth estimation, software development, and training. He has over 40 years of broad experience in the theory and practice of gravity and magnetic methods in exploration, including 25 years in the oil industry, and has provided training at several schools and workshops in basic, intermediate and advanced gravity and magnetics in the United States and overseas. Dr Saad has authored or co-authored several publications and has peer-reviewed several papers and textbooks in gravity and magnetics for Geophysics, Geophysical Journal International, and Exploration Geophysics. Dr Saad has served as Associate Editor for Magnetic Exploration Methods for Geophysics. He is an active member of the Society of Exploration Geophysicists, and a member of the SEG Gravity and Magnetics Committee, the SEG Global Affairs Committee and the Geophysical Society of Houston.
