Assessing the Accuracy of AEM Soundings

Abstract

A number of AEM surveys have been conducted for bathymetry by DSTO in recent years. Differences between the results such as `maximum depth of investigation? are easy to determine on a qualitative basis by comparison of conductivity sections or layered-earth inversions for example. However, we feel that it is important to provide a quantitative assessment of the accuracy of AEM soundings, using statistical measures.
