Robert T. (Bob) Clarke received degrees from the University of Oklahoma in geology, specializing in palynology and biostratigraphy. He began his career with Mobil Oil at the Dallas Research Lab where he was involved in the early biostratigraphic correlations of wells in Mobil's offshore Nigeria licenses. A two-year assignment in offshore exploration activities in New Orleans was followed with evaluating proposed exploration research projects that could potentially help the active exploration efforts. Bob was the Exploration Technical Training Coordinator for the exploration courses and field seminars conducted by the Research Lab for Mobil's worldwide personnel for most of the time from 1977 until the merger of Mobil and Exxon in 2000. Bob has helped organize and has taught in the AAPG Field Safety course that was initially developed by ExxonMobil for their personnel. He also continues to do desktop publishing for SEPM and for the Palynology Association. He has organized and helped conduct geology field trips for students and faculty advisors for the AAPG Student Chapter/SEPM sponsored field trips during the Annual Conventions since 1984.
