Transient Electromagnetics

The transient electromagnetic or TEM technique can be used for vertical resistivity depth sounding or profiling. The equipment consists of a transmitter and receiver which can be contained in a single box (with an external power source for the transmitter) or used with separate transmitter and receiver enclosures. The depth of exploration attained in a vertical sounding configuration can vary from 10's of meters to over 1000 meters, depending upon transmitter loop size, available power from the transmitter, and ambient noise levels. Zonge utilises industry standard equipment with the GDP-32II and SMARTem systems and can provide software for one-dimensional inversion of Transient Electromagnetic soundings (STEMINV).
