Equipment, Capabilities, Methods

DC Electrical Resistivity: 2D and 3D electrical resistivity imaging using a Supersting R8/ IP meter. With 112 surface electrodes spaced by 15 ft maximum, our electrode cables span ~1820 ft and can image to depths of ~385 ft. The major advantages of ERI are its reliability/applicability in all subsurface conditions, penetration depth, continuous profiles, and relative simplicity. Disadvantages include its moderate resolution (smoothness) and lack of mobility. Details 

Ground Penetrating Radar:  2D and 3D GPR surveys at 200-, 400-, and/or 900-MHz. We can push GPR systems using either 4-wheel or 3-wheel smart-carts. We can drag or tow systems on sled or trailer. The major advantages of GPR are its speed, accuracy, and continuous profiles. Disadvantages include the complexity of the technique and the limited penetration in areas with abundant conductive materials. Details

Sediment, Rock, Material Analysis: We collect shallow sediment cores in the field and sub-contract deeper drilling or trenching. We describe cored materials in the field and perform more detailed analysis in our laboratory.  Laboratory analyses include detailed description, particle-size analysis, carbon and water content.

GPS, GIS and Mapping: Determine geographic coordinates with a Trimble Geo 7 and classic surveying equipment. We map and analyze data in a 2.5D GIS and use 3D GIS software for 3D geologic modeling and analysis. Details
