Due to its position between the two rivers Alpheios and Kladeos, the sanctuary was covered by several metres of sediment (mainly silt and sand) after its abandonment, which complicates exploration and excavation. During geophysical and geoarchaeological campaigns in 2021 and 2023, an integrated multi-method approach containing Electromagnetic Induction, Electrical Resistivity Tomography and shear-wave seismic measurements, aiming specifically at looking below the thick sediment cover. This repositoy contains the raw data files. EMI data was measured with the GF Instruments CMD-Explorer. Positioning was done using a Stonex s9i RTK-GNSS GPS. ERT profiles measured with the Syscal Switch 48+ (Iris Instruments). Seismic profiles measured with Geode seismographs (Geometrix). The coordinates of the start and end points of profiles are in the Coordinates.txt file as well as the coordinates of coring sites and the EC log. The specific measurement configurations are noted in separate text files. en 10.57892/100-342 500 his Host institution Bäumler, Sarah cre Creator 0009-0000-1903-0785 Bäumler Sarah cre Creator Wilken, Dennis 0000-0002-5128-351X Wilken Dennis Fischer, Peter dtc Data contributor 0000-0002-8410-5824 Fischer Peter Willershäuser, Timo dtc Data contributor 1047909235 306368195 Willershäuser Timo 2021-10 2023-09 2021-10 2023-09 Olympia 21.62949 37.635529 ascii, sgy dtc Data contributor Slabon, Lena 0009-0006-1728-8655 Slabon Lena Vött, Andreas dtc Data contributor 0000-0001-7001-6225 Vött Andreas aut Author Bäumler, Sarah 0009-0000-1903-0785 Bäumler Sarah 270113181 fdr_mods_00000342 https://opendata.uni-kiel.de/receive/fdr_mods_00000342
