Geophysical Imaging and Monitoring
Near-surface geoscience in Thessaloniki
Posted on 2026/09/25
The European Association of Geoscientists and Engineers (EAGE) is a global professional, not-for-profit association for geoscientists and engineers with approximately 19,000 members worldwide. From September 20 to 24, 2026, the Near Surface Geoscience Conference & Exhibition took place in Thessaloniki, Greece. The conference serves as a platform for exchanging knowledge and advancements in the field of near-surface geophysics.
As in previous years, several conferences were held in parallel, including the 32nd European Meeting of Environmental and Engineering Geophysics, the 3rd Conference on Hydrogeophysics, the 7th Conference on Geophysics for Mineral Exploration and Mining, and the 2nd Conference on Geohazards Assessment & Risk Mitigation.
pyGIMLi workshop
The conference started on Sunday, September 20, with a series of full-day workshops at the Aristotle University of Thessaloniki. Alexander Jaron, Nino Menzel and Florian Wagner gave the hands-on workshop “Combining Near-Surface Geophysical Data with pyGIMLi”. Starting from forward modeling, the workshop covered advanced regularization with structural constraints and prior information as well as joint inversion strategies using petrophysical and structural coupling to combine complementary geophysical methods. All workshop material is openly available on GitHub.
Presentations
During the main conference, GIM researchers presented their latest work in three oral presentations:
- Nino Menzel presented “Monitoring of Rapid Flow Processes Using Adaptively Optimized Electrical Resistivity Tomography” in the session on spatio-temporal monitoring of the Conference on Hydrogeophysics (Tuesday, September 22).
- Florian Wagner presented “Tunnel-to-surface electrical imaging above an anhydrite swelling affected highway tunnel connecting Luxembourg and Germany” in the session on near-surface geophysics in engineering geology and geotechnical site investigation (Wednesday, September 23).
- Alexander Jaron presented “An open-source framework for flexible and adaptive full-waveform inversion on triangular meshes” in the session on advances in modelling, inversion, and data processing (Wednesday, September 23).
In addition, Florian Wagner chaired two sessions on advances in modelling, inversion, and data processing.
We were also happy to meet our former GIM member Dr. Hagen Söding, who is now a postdoctoral researcher at ETH Zürich. He presented “Time-Lapse Full-Waveform-Inversion under Variable Source and Receiver Coupling – a Deconvolution Method” (Wednesday, September 23).
