Electromagnetic Induction

Electromagnetic (EM) induction is process by which an EM wave is emitted from a transmitter while a receiver records modifications made to the original wave after it passes through the subsurface.  This resultant waveform can be used to interpret the physical properties of the subsurface in terms of conductivity. 

Variations of subsurface conductivity and metal content can be measured through electromagnetic (EM) induction. 

This technique can be used to locate subsurface utilities, underground storage tanks (USTs),  and contaminant plumes.

The Near Surface Geophysics Lab at Kutztown University owns a GEM 2 Multifrequency EM System from Geophex and an EM34-3XL from Geonics Limited.  The GEM 2 was obtained via the US Department of Energy's Laboratory Equipment Donation Program.  It was previously owned by Idaho National Laboratory. The EM34-3XL was donated by the Las Vegas branch of the Environmental Protection Agency (EPA).

The mapping software Oasis Montaj and Surfer are used to plot and process the data at KU.
