Comparison of Different Electrodes for Frequency Domain Induced Polarisation (IP) Surveys

B021 COMPARISON OF DIFFERENT ELECTRODES FOR FREQUENCY DOMAIN INDUCED POLARISATION (IP) SURVEYS SUMMARY 1 The influence of three different electrode types and combinations on Induced Polarisation (IP) surveys was investigated at three different archaeological sites using a SIP256 multichannelinstrument A measurement on dry loess soil yielded better results using stainless steel probes which is probably due to their larger contact surface and penetration depth. Including the results on a boggy soil one can say that Induced Polarisation in the frequency domain can be carried out with conventional metal probes. In general they lead to equal measurement results compared with non-polarisable
