Resistivity methods apply a direct current into the subsurface and measure the resultant change of voltage.  Four electrodes are used in resistivity measurements (two current electrodes and two potential electrodes).  By laying out a line of electrodes in a given array/configuration, a profile is produced to image subsurface changes in electrical properties.

This technique can be used to map stratigraphy, track contaminant plumes, and identify ore bodies

The Near Surface Geophysics Lab at Kutztown University recently acquired a DAS-1 64-electrode resistivity meter from Multi-Phase Technologies and the processing software ERTLab.
