Some of our Customers
Experts in Microgravity Surveys
A TerraDat microgravity survey is based on measuring localised variations in the Earth’s gravitational field using an extremely sensitive gravity meter. We own and operate the latest Scintrex gravimeters. A microgravity survey targets physical contrasts between materials of contrasting density. … Read More
Meet Bison “Thumper” – our seismic weight drop…
TerraDat’s expertise in shallow seismic surveying to profile bedrock and map changes in subsurface engineering properties goes to another level with the recent acquisition of a powerful weight drop source. As far as we know, it’s the only one of … Read More
GeoVoyager: A Collaboration with the Royal Society and Cowbridge School
We’re pleased to announce a partnership with Cowbridge School for an innovative educational project called GeoVoyager. The collaboration is made possible thanks to a STEM Partnership Grant from The Royal Society, the oldest scientific institution in continuous existence since 1660. … Read More
Electrical Earthing: Advanced Soil Resistivity Measurements for Electrical Earthing Design
As part of our services for energy and infrastructure, TerraDat regularly carries out soil resistivity measurements for earthing installation design and corrosion engineering. These resistivity measurements are made by passing a DC electrical current through the ground using a pair … Read More
Crosshole Seismics
Seismic methods can provide detailed information about rock properties and geological structure between boreholes. Fewer boreholes are needed to achieve a continuous picture of the subsurface, thereby reducing overall costs and the risk of missing target features. Borehole seismic methods … Read More
Magnetics
The magnetic survey technique is based on mapping localised variations in the Earth’s magnetic field caused by sub-surface magnetic materials, which range from naturally occurring magnetic minerals to man-made ferrous objects. This leads to a wide range of applications, from … Read More
Archaeological Geophysics (Archeology)
CHECK OUT OUR NEW DEDICATED ARCHAEOLOGICAL GEOPHYSICS WEBSITE TerraDat’s archaeological geophysics team is uniquely placed to draw on decades of experience in applied geophysics and archaeological surveying. TerraDat’s approach uses our fully-trained geophysicists to deal with the geophysics while our … Read More
How TerraDat’s work is helping monitor climate change
Twenty years ago, geophysics specialists at TerraDat became involved in a major pan-European project to measure the impact of climate change on permafrost in the mountains of Europe. The PACE (Permafrost And Climate in Europe) Project began monitoring a large … Read More
Slope Stability: Understanding Slope Stability using Geophysics
TerraDat has developed a strategy for investigating slope stability that provides key engineering properties for managing and monitoring existing and potential landslides. While each site is considered unique with respect to the survey design, the methods that most often prove … Read More
