Most ground models are based on boreholes, sometimes with additional 2D or 3D control provided by ‘traditional’ geophysical surveys such as microgravity, resistivity and active seismic. However, for logistical and economic reasons, these may not always be practical options for site investigations. This article showcases ‘passive’ seismic ...
Refraction seismic measurements for the determination of the seismic velocities in the shallow subsurface have been performed close to Valence (F) for our partner Partner Gallego Technic Geophysics. 44 profiles with a length of 240m have been acquired in August 2016. Seismic velocities of the shallow geological layers and the ...

As part of the geotechnical study, GeoView, Spotlight Geophysics and ATI Panamericana were tasked to provide seismic P-wave and S-wave velocity structure of the subsurface. The consortium collected seismic refraction and multi-channel analysis of surface waves (MASW) data along survey transects approximately 4 kilometers in length. ...
In support of their characterization efforts, GUPC requested that seismic geophysical data be acquired at four locations within the project area. ...
Because of the large contrast in both seismic velocity and electrical resistivity, the geophysical investigation was conducted using a combination of p-wave seismic refraction and electrical resistivity imaging (ERI). Both 2-dimensional and 3-dimensional data was collected at the site. A total of 2,300 ft of Seismic ...
PROJECT: Refraction and ReMi geophysical surveys at a proposed Wind Farm LOCATION: West of Ellensburg, Washington PROJECT DESCRIPTION: Designed and performed seismic refraction / ReMi surveys at 22 proposed Wind Turbine Generator sites for the primary purpose of obtaining shear-wave (Vs) and compressional-wave (Vp) velocities. ...
ReMi Surveys are superior to MASW Surveys in the following ways: Ambient (ie, traffic and aircraft) “noise” is a hindrance to MASW surveys, yet is readily embraced / utilized by “passive” ReMi surveys Longer ReMi data records (ie, 30 seconds vs 8 seconds or less with MASW) capture lower frequency events We introduce high frequency impulsive energy that augments low ...
” The Solution After the initial modeling, Erskine looked for something more concrete. After looking into seismic refraction and a geothermal surveying company that could provide limited data, he called upon Willowstick, makers of AquaTrack(TM), which seemed to be the perfect fit for the quarry project. ...
The results of location of karst wells and probable hydraulic connections between them in limestone massif using the refraction tomography are presented. Seismic modeling was based on refraction horizon recognition in the first stage and tomographic processing of P-wave and S-wave velocity changes in the second one. ...
