Integrating ground-penetrating radar and traditional stratigraphic study in an undergraduate field methods course

Georgia Southern University maintains a traditional geology curriculum for both bachelor of science (B.S.) and bachelor of arts (B.A.) degree candidates. Field experiences figure prominently in our curricula, and students have been taught to use traditional means of gathering and recording field data (e.g., Brunton compasses and notebooks with sketches). We have recently introduced high-resolution geophysical investigations that are focused particularly on ground-penetrating radar. A nearby field location, known as Middleground, offers an excellent road cut with sufficient exposure, lithological heterogeneity, and relief to conduct both geological and geophysical investigations. We have shown students how one technique contrasts with the other, and how they can be used to support each other. Student reactions to the Middleground ground-penetrating radar exercise have been positive and enthusiastic, and have led us to formulate new and diverse applications of ground-penetrating radar to assist students in developing their three-dimensional visualization skills and a greater understanding of geophysical techniques in field investigations.
