Caves are important for a wide variety of work fields, ranging from construction engineering to mineral exploration and archaeology. Despite their scientific importance, geologists expect that only a relatively small number of caves have been discovered so far. Current exploration efforts are mainly done by speleologists, but this is a time-consuming activity and limited to exploration based on existing surface openings. The authors of this article show that the combination of multiple geophysical techniques provides an easier and effective on-surface exploration method that meets the challenges of complex karst environments.
