Abstract :
Results of SQUID application in geophysical time domain transient electromagnetic (TEM) measurements are presented. We analyze peculiarities of SQUID TEM recordings, comparing them to data of commonly used induction coil. Two significant effects have been observed with the SQUID TEM system which are less pronounced or not observed in corresponding reference coil data. We consider a model for SQUID TEM measurements, taking into account the effect of repetitive transmitter signals which gives a possible explanation for these effects
