BGS Geophysical Tomography (GTom) provides leading-edge technology for non-invasive, geoelectrical imaging of the shallow subsurface.
The techniques (instrumentation, software and methodologies) developed by GTom are used to underpin studies in infrastructure monitoring, waste management, contaminated land remediation and the protection of groundwater and soils, as well as the detection and mitigation of natural hazards. Our PRIME technology permits complex earth systems and processes to be monitored remotely using permanent, in situ sensor networks and wireless telemetry.

Applications
Applications range from mineral exploration and waste management, to monitoring active processes within the subsurface, such as the movement of pollutants, or the flow of groundwater in unstable slopes affecting infrastructure.
Technologies
Creating innovative technologies with in the field of geophysical and geotechnical monitoring.
Our projects
Waste management ALERT project
Thw Waste Management ALERT project aims to develop a non-invasive, 4D, electrical imaging system for automated time-lapse monitoring of landfill sites.
Contaminated land ALERT
Time-lapse geoelectrical imaging has the potential to produce volumetric, time-dependent maps of contaminant distributions for use in contaminated land remediation.
SENSOR NET
Studying soil moisture content via sensor networks to design the most efficient sample network.
