Electrical Resistivity
Multi-electrode Electrical Resistivity
Multi-electrode Electrical Resistivity is an advanced, non-invasive geophysical technique that provides a detailed snapshot of the underlying geology. Our Super Sting unit employs 28 to 112 electrodes attached to a cable. Computer programs in the Sting unit manage the sequencing of arcing electric currents through the electrodes depending on the method chosen for recording.
Continuous Resistivity Profiling
The Continuous Resistivity Profile (CRP) surveys use the same concept as the Multi-electrode Electrical Resistivity (MER) surveys. The system computer operates a dipole-dipole array as the cable is towed behind a boat. A sonar and GPS units continuously record depth and position.
NSN uses a combined approach of the most advanced geophysical methods including Multi-electrode Electrical Resistivity and Cone Penetrometer Testing to provide detailed results for your critical investigations.
