N2  - The results presented in this paper show that in the Inductive Source Resistivity (ISR) technique, the transient decay of E field data can be used to calculate an apparent background resistivity (or, in the case of conductive overburden, an apparent background resistance); which can then be used to estimate an apparent transverse resistivity (apparent transverse resistance) from the late-time measured electric field data. This estimate thus makes the presentation of ISR data more meaningful in terms of modelling or interpretation with quantitative physical properties. The development of capacitive electrodes allows for measurement of the ISR, a direct current electric field response of the ground, without the need for ground contact of either the transmitter or receiver electrodes.
