Geonics EM38

The Geonics EM38 is a frequency-domain electromagnetic geophysical instrument designed to measure bulk soil conductivity, also known as apparent conductivity. The instrument has an effective depth of penetration, or skindepth, of approximately 1.5 meters, and is often used in conjunction with the Geonics EM31 to obtain generalized depth information. The instrument has a shallower skindepth than the EM31, and a smaller footprint. As such, the tool will not detect deeper ion concentrations but will produce higher resolution maps and is less prone to interference from nearby electrical sources and metal infrastructure.
