E022 FULL SCALE EM MODELLING ON SEA ICE Introduction 1 H. HONGISTO J. JOKINEN T. JOKINEN H. SÄÄVUORI and M. OKSAMA Geological Survey of Finland (GTK) P.O.Box 96 FIN-02151 Espoo Finland EM measurements using the STROB - transient electromagnetic system (TEM) and the SAMPO - frequency-domain wide-band electromagnetic sounding system were carried out on sea ice to test the resolution and accuracy of the equipments. For EM-methods sea ice is an ideal place to make test measurements in a simple and well-controlled environment. Also appropriate parameters can be determined accurately enough so that responses to be measured can be easily
