Abstract
In a land management context, conductivity can be related to quantities such as salt store, ground water salinity, clay content, hydraulic permeability, degree of groundwater saturation or more generally to definition of regolith and bedrock units. These relationships open the way for the use of electromagnetic methods to measure subsurface conductivity. From the very early trials, efforts have been made to transform the measurements to conductivity. The real world presents a myriad of difficulties, that translate into errors and artifacts in 2D sections or 3D volumes produced from individual 1D conductivity transformation solutions. Reconciliation of AEM conductivity predictions with other spatial information presents a deceptively difficult challenge. A variety of improvements in the future will lead to a more accurate portrayal of conductivity in 3D.
