Geophysicists and Geophysical Equipment Rentals
for engineering geophysics are found at EngineeringGeophysics.com
Find a geophysicist through GeophysicsSurvey.com for surveys like MASW, GPR, electrical earth resistivity imaging, seismic refraction, seismic reflection, underground line locating, electromagnetic terrain conductivity, archaeology, graves, or ground vibration monitoring. Concrete scanning services, which are like concrete X Ray services, are popular in the fields of construction or demolition of highways, roads, bridges, and buildings. Finding a concrete scanner with a background in geophysics is often needed. Locate geophysical equipment rentals or visit K.D. Jones Instruments for a variety of engineering and geophysical applications. Other disciplines (Θ see below) utilizing engineering geophysics and geophysical applications are discussed. Some disciplines include frac sand exploration, archaeological geophysics, mine planning, levee certification, design, and mapping, geophysical classifieds, geophysical equipment sales, multichannel analysis of surface waves MASW applications and methods, geophysical proposals, geophysical training, line locator equipment, and underground line locating. Each link offers a blog about the primary geophysical method of the site. People are welcome to add comments to the blogs. More enthusiastic persons can request to write for their favorite blog.
Engineering geophysics use instruments from many manufactures. SuperSting and MiniSting multi-electrode earth resistivity imaging systems are built by Advanced Geosciences, Inc.. Sensors & Software has decades of experience building ground penetrating radar GPR systems as does Geonics with their EM-61 EM-31 EM-34 EM-38 instruments. Geometrics pioneered a wide range of geophysical equipment, like instantaneous floating point seismographs (from the older 2401 to the new Geode), magnetometers G-858 G-856, and the OhmMapper capacitance coupled towed resistivity array. Instantel specializes in ground vibration monitoring seismographs, geophones, accelerometers, and microphones. In addition to the above, magnetic susceptibility meters, borehole logging tools, underground utility locators, and other geophysical applications can be found at the above link to equipment rentals.
Seismic methods include discussions about seismographs, geophones, accelerometer, cables, software, and seismic sources for seismic refraction, seismic reflection, MASW, and shear wave surveys. Electrical resistivity addresses resistivity soundings, multiple electrode resistivity MER systems, and towed arrays. Wenner, Schlumberger, Dipole-Dipole, Pole-Dipole, Pole-Pole, or user defined) arrays offer unlimited options. Ground Penetrating Radar GPR includes topics about antenna options for geologic mapping, concrete scanning, underground utility locating, depth of penetration, mapping voids, and even finding graves. Electromagnetic EM methods are popular for measuring apparent soil conductivities or locating buried metal. Magnetometers used to map archaeology sites, landfills, and USTs can provide insite that other geophysical methods can not provide. While many utility locating companies do not have the above EM methods or total field magnetometers, their services would be enhanced if these near surface geophysical methods were implemented. Ground vibration monitoring is discussed so mine engineers, geophysicists, demolition specialist, and manufactures can fine tune their programs and better assist the public concern.
