Powerline contamination in time-domain electromagnetic data : experiment, theory, and basic building blocks
MetadataShow full item record
Time-domain Electromagnetics (TEM) is a powerful tool to image the conductivity structure of the subsurface. These systems can be ground-based or can be mounted on an airborne platform, which allows for greater data density and resolution. Airborne electromagnetic (AEM) surveys are continually being pushed to regions with increasing culture; regions such as producing oil-fields with a need of ground-water contaminant monitoring, populated agricultural regions for water resource management, and/or mineral exploration around existing developments. Culture and cultural noise are proportional, and ...
