| contents | This dataset represents frequency domain Electromagnetic induction (EMI) data created by using electromagnetic waves generated in a transmitter and recorded in three receiver coils to create maps of electromagnetic subsoil properties at different sensing depths. A CMD Mini-Explorer by GF Instruments was used. The device consists of one transmitter and three receiver coils. The planes of the coils were oriented horizontally (horizontal coplanar - HCP). The distance between the transmitter and receivers are 0.32 m, 0.71 m and 1.18 m. The measurements were performed with 10 Hz sampling frequency. The area was covered by randomly walked W-E-orientated and N-S orientated tracks with an average spacing of about 0.5 m between the tracks. An RTK-GPS (Stonex S9i) was connected to the device using a fixed fibreglass rod at a distance of 2 m to the coils, minimizing the influence of the electronics on the data. The data was collected July 21st 2020, to image a 17th century wooden ship wreckage in the North Sea tidal flat area west of the island of Hooge(Germany) (Coordinates, geographic WGS84, are provided in the data list). |
