Applied Geophysics

We develop and use ground-based, marine and airborne geophysical techniques, especially for electromagnetic exploration to derive physical properties of the earths subsurface from few meters depth down to several kilometers. Our areas of applications cover a wide range such as the search for groundwater, contamination problems, mineral resources and hydrocarbon exploration, geothermal research and archeological prospection as well as general geological studies

What is applied geophysics about?

Key Research Areas & Methods
