Resistivity is an electrical geophysical method that offers deep depth penetration and high resolution, is not sensitive to conductive soils like electromagnetics and ground penetrating radar, and is a lower cost alternative to seismic reflection.
2-D and 3-D resistivity surveys are designed with site-specific parameters and array types to provide the best subsurface imaging possible. The state of the art multichannel resistivity system that Bay uses is faster and more powerful than single-channel systems and is capable of conducting large 3-D surveys with thousands of electrode stations.
Some applications of resistivity include:
- Void and karst topography mapping
- Subsidence investigations
- Bedrock and stratigraphy mapping
- Fault and fracture delineation
- Ground water studies
- Mineral exploration
