This data set contains raw and processed data of a prepolarized surface nuclear magnetic resonance (SNMR-PP) experiment over a water basin, which uses an alternative excitation mechanism. Different receiver loop configurations (circular - circ, figure-of-eight - foe) were installed on a fixed platform and measurements were carried out at different basin water level heights. Please unzip the archive files "data_set.zip.00*" with e.g. 7-zip (or any other zipping tool) to find a folder structure and the corresponding README file.
