. This study is based on the use of geophysical investigations, in this case of a geoelectrical method, in order to identify underground cavities. The purpose was to identify, delineate and measure underground cavities. We used DC current geoelectrical measurements on profiles, by performing vertical electrical sounding measurements (VES) by the Schlumberger method, such that the lateral effects were attenuated as much as possible. Our studies focused on three areas, located close to the Mangalia town, the Limanu and Movila Caves (where the boundaries of the cavities are relatively known), as well as a new area that proved interesting as a karst zone (Obanu Blebea). Where possible, we performed the correlation between geoelectrical data and geological information including borehole data
