by a powerful airgun in the water column and propagate through the water and sub-bottom strata. Refracted P-waves are sensed by a hydrophone streamer and recorded by a seismograph. The data are processed to produce a continuous P-wave velocity cross-section, from which geologic interpretations and mapping are ...

, they represent the first arriving energy at each geophone (either direct or refracted). A seismograph is used to record the travel-times of the first arriving energy, after which subsurface seismic P-wave velocities can be derived. A tomographic inversion is used to develop a 2D P-wave velocity cross-section from the data. Seismic refraction data ...

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 ...

Dynamic, high-quality measurements of displacements and strains can be made by using video monitoring technology, even in situations that do not allow access or instruments. In 2007, Imetrum launched a measurement system for video monitoring (known as Video Gauge™) that has become the video monitoring standard. Video Gauge™ provides measurement versatility far beyond any other ...

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 or 3 dimensional perspective of subsurface ...

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 seismic vibrator, commonly known by the trademark name ...

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 penetration depths up to 50 meters. It is useful ...
