Seismograph services

  • Seismic Methods

    All seismic methods measure the travel-time and frequency of elastic waves as they propagate through the subsurface. The methods commonly used in shallow geophysics involve using an impact source (hammer, weight drop, explosive source) to generate the seismic wave and recording the arrival of the waves with a seismograph and a series of geophones. ...

  • Marine Seismic Refraction Services

    Marine seismic refraction is a method to determine the seismic P-wave velocity structure of the subsurface. The P-wave velocity is related to the hardness of the sub-bottom materials and can be used to map the top-of-rock, determine the dredgeability of sub-bottom materials, and identify anomalous conditions. Seismic P-waves are generated by a ...

  • Seismic Refraction Services

    Seismic refraction is a geophysical method used to determine the seismic compression-wave (P-wave) velocity structure of the subsurface. Seismic P-waves are generated on the surface, propagate through the soil and rock, and are recorded by geophones at known distances from the source. Since P-waves are the fastest portion of the seismic wave, they ...

  • Exploration Services

    Information on stratigraphy and structural geology is often scarce. Geophysical results are an essential source of data for every geothermal, mining or oil & gas prospect. Geophysics is the cheapest way to obtain geological information up to several kilometer of depth.

  • Scanning Beneath the Seafloor Services

    GeoView employs three methods for studying the geologic strata and objects buried beneath the seafloor. These include Sub-bottom profiling, Marine Seismic Refraction and Marine Seismic Reflection. GeoView owns and operates an Edgetech sub-bottom profiler. It generates a swept frequency source to produce a high resolution image of the sub-bottom at ...

  • Residential/Commercial Sinkhole Studies Services

    The investigation of potential karst (sinkhole) activity at residential or commercial properties or undeveloped land is a multi-disciplinary process in which geophysics plays a critical role. Subsurface geology in karst environments is very complex and is often masked at the surface. Properly selected and applied geophysical tools will provide a 2 ...

  • Seismic Services

    Seismic Reflection Reveals What is Under the Surface. We use seismic reflection as a method of geophysical exploration that uses the principles of seismology to estimate the properties of the Earth's subsurface from reflected seismic waves. The method requires a controlled seismic source of energy, such as dynamite, a specialized air gun or a ...
