There’s an urgent need for more studies of European permafrost, says the leader of a TerraDat team which has just completed a new geophysical survey in the high mountains of Spain. Professor Christian Hauck’s team repeated readings in the Sierra Nevada mountains 20 years after the company was an intrinsic part of a pan-European study into permafrost in high mountain areas. Permafrost is permanently-frozen rocks, sand, gravel, and soil, with much of it originating from the last Ice Age. Recently [...]

The North of Spain is home to some of the most impressive Roman remains in the world. From rich villas and roads trodden by generations of centurions to thermal baths and fortifications.Now, a TerraDat team has helped archaeologists to uncover the largest Roman mosaic in Asturias. At almost 11m long by 4m wide, the mosaic’s detailed pieces show classical patterns and knots.Team leader and Senior Geologist/Geophysicist Dr Javier Olona said: “The ground penetrating radar (GPR) gave a clear sign of [...]
Satellite technology is giving scientists a new source of information to help us measure movements in the Earth’s surface – and that could help us protect the infrastructure of Wales. The European Space Agency’s Sentinel-1 mission is now providing a wealth of open access SAR (Synthetic Aperture Radar) data for both academic and commercial purposes. The geo-engineering and geo-environmental sectors are just starting to explore the use of this data to monitor ground movement at man-made structures. To make the [...]
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 its kind in the UK and has significant benefits over other seismic sources, not least it's power and portability. We acquired the equipment in 2017 and it has undergone extensive refurbishment at our HQ in South Wales. The US-manufactured Bison [...]
A map of Europe showing the location of the Sierra Nevada mountain range. Courtesy of free maps at https://mapswire.com/countries/spain/. 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 area of permafrost between Svalbard in the north and the Sierra Nevada mountains in Spain in the south. The study, [...]
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 past. TerraDat worked in partnership with Swansea University to produce the video, “Echoes of Copperopolis”, and a 3D digital model of the Hafod-Morfa Copperworks, which was once the crucible of the world’s copper industry. It was hugely important in the [...]
