%X As a check on direct current measurements of the transmitted waveforms as measured with a wideband transducer, we monitored the EM field of the SeaTEM system during several flights over a ground loop. The ground loop was laid out over very resistive granite in Western Australia. Ground measurements were made of the current and voltage induced in the ground loop. For the first time, we also collected point-sampled total field and component magnetic fields using commercial sensor systems to investigate the effectiveness of direct B field rather than dB/dt measurements.
