STING R1 Resistivity Imaging

A geophysical technique for imaging sub-surface structures from electrical resistivity measurements made at the surface by putting electrodes in the ground. Composed of an automated 56-channel system from AGI, with max 10 meter electrode spacing. Related software available for 2D and 3D inversions.

GPR

GPR - PULSE EKKO

A geophysical method that uses radarpulses to image the subsurface. GPR uses high-frequency radio waves. A GPR transmitter emits electromagnetic energy into the ground. When the energy encounters a buried object or a boundary between materials having different permittivities, it may be reflected or refracted or scattered back to the surface.Equipped with a 50, 100 and 500 MHz antenna.

Magnetic susceptibility meter

Magnetic susceptibility meter KT-10 from TerraPlus SM20 from GF Instruments is designed especially for field analysis and classification of rock types or drill core samples. Those measurements allow basic differentiation of rocks (diamagnetic, paramagnetic and ferromagnetic) and their precise susceptibility quantification.

Time-domain EM

Time-domain EM (TEM-FAST) is  geophysical tool for time-domain electromagnetic sounding. Will provide 1D measurements of varying conductivity with depth, when spatially repeated can deliver 3D subsurface models.

EM31

The EM31 - Geonics (and its family EM34, and EM38 systems) measure  the terrain conductivity, in phase response, and indirectly magnetic susceptibility of rock, soil, fill, pore fluids, and metal using frequency domain electromagnetic waves. The system has no datalogger connected to it.
