Experiments with the square array

Electrical resistance data were collected in an electrolytic tank, using the main configurations of the square array, in order to assess the behaviour of the system over an insulating sphere and prism. Experiments carried out were: mapping of area responses for targets at a fixed depth and the effect of strike direction and electrode separation on anomaly form; production of pseuclosections; investigation of the depth response of the array at different electrode spacings. Field tests were carried out on a selection of sites in the UK in order to examine the findings of the laboratory experiments. Copyright (c) 2005 John Wiley & Sons, Ltd.
