What is the difference between ERT and TEM for shallow depth...

I think it's possible to get correct apparent resistivity to shalow depth as 1 m or less using TEM. I study the principle of current TEM instruments and tested some TEM instruments. I find that no TEM instrument can satisfy the requirement of shallow depth exploration. The problems exist in transmitter, receiver, and sensor.

The side length of the loop depends on the desired depth of exploration. For shallow depths (less than 40 m) in relatively resistive ground, the length may be as small as 5–10 m. The TEM techniques are effective for determining electrical resistivity or conductivity of soils at different depths. Since electrical resistivity of soil...
