Entry from British & World English dictionary
The measurement of the current passing between electrodes embedded in the ground at a series of positions over a given area, in order to locate buried structural features by their differing resistivity.
- Because it works through induced fields, there is no need for direct coupling to the ground, as is needed for electrical resistivity surveying.
- Resistivity surveying can play an important role in environmental and engineering investigations.
- Furthermore, the group of features detected by both magnetometry and resistivity surveying in square 7 may also represent the remains of ruined structure associated with the Abbey.
