Understanding the Fundamentals of Electromagnetic Methods

Electromagnetic (EM) methods are a cornerstone of modern geophysical exploration. These techniques involve the use of electric and magnetic fields to image subsurface structures and features. The EM methods covered in the Global Certificate program include:

1. Time-Domain EM (TDEM): This technique measures the response of the subsurface to a time-varying current source. It is particularly useful for detecting conductive materials, such as metallic minerals or groundwater.

2. Frequency-Domain EM (FDEM): FDEM measures the response of the subsurface to a steady current at different frequencies. It is effective for imaging both conductive and resistive materials, making it versatile for a wide range of applications.

3. Audio-Magnetic Sounding (AMS): AMS uses a pulsed magnetic field to investigate the subsurface. It is particularly useful for shallow investigations and can provide information on the depth of mineralization.
