Practical Geophysical Methods of Cave Detection
Atanas Rusev, Tanya Slavova
Geophysical methods of cave detection have, to date, reaped few positive results in finding new caves. As and report, however, this isn't inevitable. Here they describe cave detection, using ground-penetrating radar, magnetometry, gravimetry and infrared imaging, and illustrate the techniques with case studies showing the discovery of new caves and entrances.

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.
Underground Cave Detection by Gravimetry
Abstract of Dissertation
Tanya Slavova
Both natural and man-made underground cavities are features that could give the answers to variety of questions. This dissertation is dedicated to both colleagues in geodesy and a broad range of other scientists and explorers. The results are of interest for specialists in speleology, geology, geomorphology, hydrogeology, mineralogy, biology, archeology, etc., and that is what defines the multidisciplinary significance of the problem.
Invitation for a PhD Defense... My PhD Defense
It is available only in Bulgarian however the language of photography gives a glimpse on the field work. Although it took about a month, it marked my dissertation. And it wouldn't be possible without the support of my friends, some mentors and organisations - some help that I greatly appreciate.

A Tale About the Living Water and Gravimetry
Analysis of the Applied Gravimetric Techniques for Detection of Underground Cavities
Tanya Slavova
Gravimetric methods are based on the natural gravity field of Earth. Measuring it with high accuracy and resolution makes it possible to resolve a variety of issues - from fundamental problems to tasks of small scale but large significance. Technological progress during the last decades have also expanded the applications, and the principle, which gravimetric methods are based on, confirmed their applicability for certain targets.
Cavities are features with typically high density contrast to the surrounding rock. On one hand, their detection is a classical gravimetric task. On the other hand, exploring their exact location, shape and size is an important issue for engineering, various sciences and ecology.
