Datasets are: Frequency domain electromagnetic induction (CMD-Explorer by GF-instruments, in HCP mode, carried 1m above surface, 10Hz sampling, RTK-DGPS data was collected using a Stonex S9i). The data is available as processed, binned geotiff EPSG 32634 (cond1-cond3 and IP4-IP6 referring to quadrature(apparent conductivity) and inphase component of the increasing coil distances). The binned dataset was inverted for each bin in 1D resulting in a pseudo 3D cube, saved as standard vtk-file. Raw data is provided as ascii-file (.dat files) Magnetic Gradiometry data using an array of six Foerster Fluxgate gradiometers (sampling 20Hz), positioning with Stonex S9i RTK-DGPS. The data is provided as binned geotiff EPSG 32634 Electrical resistivity tomography profile SAM ERT 17, measured with a syscal R1+switch 48, with 48 electrodes. Measurements were done in Wenner‐Schlumberger configuration. The subsequent least squares inversion was accomplished using the RES2DINV (Loke and Barker (1996)) software, involving iterations until a final absolute error of 2.2 Ωm. For the inversion, an initial damping factor of 0.1 and a minimum damping factor of 0.03 was used. The root mean square (RMS) convergence limit was set to 5 %. Data is provided as .INV ascii format comprising electrode positions and elevations on profile and apparent resistivity values. Absolute electrode positions are attached as shape-file (ERT17.shp). 2021 2023 database Wilken, Dennis Author aut Vött, Andreas Creator cre Wilken, Dennis Creator cre Fischer, Peter Contributor ctb Faculties Faculty of Mathematics and Natural Sciences host institution his https://opendata.uni-kiel.de/receive/fdr_mods_00000343 object in context https://opendata.uni-kiel.de/servlets/MCRFileNodeServlet/fdr_derivate_00000347/SamikonKleidi_2021and2023.zip raw object https://opendata.uni-kiel.de/rsc/thumbnail/fdr_mods_00000343.png preview https://opendata.uni-kiel.de/receive/fdr_mods_00000343 uri
