[1] Six different geophysical investigations, (1) ground-penetrating radar, (2) DC resistivity sounding, (3) seismic refraction, (4) very low frequency (VHF) electromagnetic, (5) helicopter borne electromagnetic (HEM), and (6) transient electromagnetic (TEM) techniques, were employed to obtain information on the ice body properties of pingos near Fairbanks, Alaska. The surface nuclear magnetic ...

Maps of sedimentary physical properties are essential to a complete understanding of processes shaping the continental shelf. We have demonstrated that measurements of electrical resistivity can provide exciting new insights into shelf structure. But there is more work to be done in tying results of electromagnetic (EM) studies to those of more conventional surveys such as the extensive coring ...

Geophysical site characterization investigations at fuel spill sites have been generally guided by a working hypothesis Ž . which assumes that the light non-aqueous phase liquids LNAPL are a fully saturating phase of intrinsically very high electrical resistivity. Using observations from other related sciences, and contrary geophysical observations, a different model is developed which treats t...

Electrical Resistivity Methods involving Schlumberger Vertical Sounding (VES) and Wenner Profiling (EP) were carried out to map the Geological features of earth subsurface in Zainawa Area Kano State, Nigeria. Five profiles established; consist six (6) VES points at each profile. GEOPULSE resistivity meter (SAS 300) was used for data acquisition. The field obtained have been analyzed using compu...

This work presents a methodology for horizontal soil stratification and device 3D mapping using the discretization of Wenner’s method. The starts from application lateral profiling method in conjunction with to find experimental resistivity curve. Sunde’s algorithm is used construct theoretical By utilizing these curves, it possible apply optimization process parameters: electrical conductivity...
