Surface-NMR

The research field surface-NMR advances the technique to conduct NMR experiments by using large coils placed at the Earths surface that allows for deriving hydrological parameter.

Surface-NMR is a relatively new geophysical technique based on the same principles of the well known medical MRT. Surface-NMR allows for deriving subsurface distributions on hydraulic parameter such water-content and permeability. Our Research focuses on the development of improved data processing algorithms, innovative measurements sequences and loop layouts and includes the development of new technical devices. In close cooperation with  the modelling and inversion group, advanced techniques for joint inversion with the georadar and geoelectrics are developed. Our research mainly targets hydrogeophysical questions and thus finds application in the research focus field groundwater. Together with laboratory- and logging-NMR scale independent research is undertaken.
