Transient Electromagnetic Geophysics Equipment TEM Survey resistivity meter with GPS Receiver and PAD Operation
Transient Electromagnetic (tem) method is perfectly suited to locating groundwater and minerals, but also useful for applications such as geological mapping and environmental surveys.
The classical DC methods, such as vertical electric sounding (VES) and electrical resistivity tomography (ERT), are often used for the shallow subsurface . DC surveys, which have been in use for over one hundred years, measure the electric field on the surface controlled by subsurface resistivity. Electrical tomography is advantageous in its simplicity, high performance, ability to resolve near-surface after depths of tens of centimeters, and relatively straightforward processing algorithms.
Unlike the DC resistivity surveys, the apparent resistivity in transient electromagnetic (tem) measurements is inversely proportional to the signal: the more conductive the earth the greater the induced eddy current. Thus transient electromagnetic (tem) can support up to 1000m underground detection
The transient electromagnetic (tem) soundings are commonly run by multioffset transmitter-receiver systems with square ungrounded loops.
