WHAT IS TEM?
The TEM (Transient Electromagnetic) method is a geophysical technique used to obtain vertical resistivity soundings, focusing on conductive materials that exhibit significant responses. This non-destructive approach involves the use of wire loops to transmit and receive signals in the subsurface, ensuring minimal disturbance to the survey area and leaving no residual marks after measurements are completed.
WHAT CAN IT BE USED FOR?
Transient Electromagnetic (TEM) can be used for:
HOW DOES WTEM WORK?
WTEM works by transmitting electromagnetic pulses into the ground using a transmitter loop. These pulses induce currents in the subsurface, which generate secondary electromagnetic fields. Receivers measure the response of these fields, allowing the interpretation of subsurface resistivity variations.
