River Crossings: Profiling Geology using Geophysics
Many of our clients constructing roads, laying pipelines or investigating historic bridges find profiling the geology beneath rivers tricky using conventional ground investigation methods. Since the path rivers take is often dictated by changes in geology, the problem can be … 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
How we brought the evocative story of Swansea’s copper heritage to life using 3D Reality Capture
An evocative video combining the oral history of one of Wales’ most important industrial sites with a 3D digital model created from laser scan surveys are preserving its heritage for future generations as well as connecting local communities with their … Read More

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
Peat Mapping using Geophysics (Peat Surveys)
Mapping peat is a common requirement for proposed developments such as wind farms and pipeline routes where they cross remote and/or sensitive areas. There are several geophysical methods that can provide plan and cross-sectional information to map the distribution of … Read More
Electrical Resistivity Tomography (ERT)
The Resistivity technique is useful for characterising the sub-surface materials in terms of their electrical properties. Variations in electrical resistivity (or conductivity) typically correlate with variations in lithology, water saturation, fluid conductivity, porosity and permeability, which may be used to … Read More
Geophysics for Mapping Geology along Pipeline Routes
Pipelines and cable routes present a set of unique developmental and geotechnical challenges. TerraDat has designed an integrated survey approach, providing data useful to all stages of the project design. Archaeological assessments and UXO detection: Due to the large distances … Read More
Ground Conductivity (EM)
A ground conductivity or electromagnetic (EM) survey involves the generation of an EM field at the surface and subsequent measuring of the response as it propagates through the subsurface. The main components of the instrument are a transmitter coil (to … 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
