Conducted in close partnership with the Ministry of Water and Energy of Ethiopia and Addis Ababa University, the survey aims to improve understanding of the Basin’s hydrogeological settings under different geological and environmental conditions. The contractor must collect high-resolution TEM and magnetic data, capable of imaging layers as thin as 3 meters near the surface and achieving penetration depths of up to 500 meters, while meeting strict technical, calibration, safety, and data-delivery requirements. The project includes joint flight-line planning, rigorous system testing and documentation, and delivery of data ready for processing in Aarhus Workbench, all within a maximum budget of 5,000,000 DKK. ## CPV classification Geophysical consultancy services Subsurface surveying services Source Tenders Electronic Daily (EU) · Notice 117467-2026 [View official notice](https://ted.europa.eu/en/notice/117467-2026) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
