Noise reduction in a mobile, continuous operation TEM system - Loupe

Summary

Loupe is a new generation of time-domain electromagnetic (TEM) instrument designed for profiling and mapping in the near surface. It employs a two man backpack-mounted transmitter-receiver combination for rapid continuous data acquisition. In addition, a trailer-mounted version is under construction.

Interference from a range of sources is a significant problem for TEM systems. Problems are exacerbated when surveys are undertaken in urban areas.

This paper will present case histories from a range of applications including mapping buried rubbish, saline incursion, shallow sulphide exploration, graphite exploration and tailings dam assessment.
