Electromagnetic induction (EMI) data at the Roman Burgus of Astheim

EMI data measured with the GF Instruments CMD-Explorer. Positioning was done using a Stonex s9i RTk-GNSS GPS. Measured at a Roman river fortlet (burgus) site in Hesse (Germany). During the 1st century AD the Romans performed several river alterations in the vicinity of the River Rhine in Hesse, including channels, holding anchoring sites protected by these burgi. The regarded example profiles crosses such a channel. In the middle of the assumed channel, a direct push EC-log was performed along site a hydraulic profiling tool, using a Geoprobe 540 MO system mounted to a Nordmeyer drill rig in combination with a Geoprobe K6050 HPT probe.
