Ground Conducitivity Meter
The ground conductivitity meter is an EM method where coils transmit an electromagnetic field and the response of the ground is measured, it is also known as a slingram method. Bargheer Geophysics are cabable of delivering several different GCM methods.
A much used method in Denmark is pulling the GCM instrument from with an ATV where we are able to collect much data in a short time. Using this method on good field conditions it is possible to collect in access of 50km of data in a field day, making it a very cost effictive tool for mapping the electric variations in the top 5-8 meters of the subsoil.
Applications for this method include:
- Archelogical mapping
- Geotechnical investigations, a great supplement to the traditional drillings
- Mapping of the size of old landfills
- Finding best sites for rainwater drainage
- Drainage piping planning for agriculture
- and many other uses
