Risk, G.F. 1974 Electrical resistivity soundings of peat deposits on Chatham Island. [s.l.]: [s.n.]. Report / Geophysics Division 92 24 p.

Abstract: The resistivity of water-saturated peat on Chatham Island is between 25 and 50 ohm m. In many parts of the island a sand formation, which has approximately the same resistivity as the peat, lies beneath the peat. The interface between the peat and sand could not be detected using the Schlumberger resistivity sounding technique because there is insufficient contrast in resistivity between the layers (auth.)
