The Role of Airborne EM Methods for Environmental Applications in Different Geological Terrains

IA-2 THE ROLE OF AIRBORNE EM METHODS FOR ENVIRONMENTAL APPLICATIONS IN DIFFERENT GEOLOGICAL TERRAINS Abstract 1 This paper reviews the increasing role of Airborne EM (AEM) methods for environmental purposes in a variety of geological contexts. The ability of AEM data to differentiate geological cultural and environmental influences is considered using fixed-wing survey examples from Finland and the UK. The provision of AEM subsurface resistivity information constitutes a unique capability in relation to general remote-sensing information to which it is allied. To be fully exploited the results of AEM surveys require both ground calibration and integration (e.g. through GIS techniques)
