Provision of an airborne geophysical survey of the Rift Valley Basin in Ethiopia

Beskrivelse fra ordregiveren

Aarhus University seeks a contractor to carry out a large-scale airborne geophysical survey of the Rift Valley Basin in Ethiopia in early 2026, using a helicopter-based slung-load transient electromagnetic (TEM) system and magnetic instruments to map shallow and deep hydrogeological structures. 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.
