Geophysics: Refraction / ReMi surveys at a proposed wind farm
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. This information enabled the client (major geotechnical firm) to ...

Seismic refraction for weather zone assessment in vibroseismic processing
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 bedrock could be determined to a depth of up to 25m. Results from ...

Seismic study at the Pacific and Atlantic locks of the panama canal case study
Panama Canal Zone Grupo Unidos Por el Canal (GUPC) was tasked with characterizing subsurface conditions within the Third Set of Locks Project for the Panama Canal. In support of their characterization efforts, GUPC requested that seismic geophysical data be acquired at four locations within the project area. These locations include portions of the: Miraflores Cofferdam Atlantic Approach ...

Seismic refraction and MASW case study
Proposed Gatun Bridge, Colon, Panama The Autoridad del Canal de Panama (ACP) conducted a geotechnical investigation along the footprint of a proposed bridge crossing of the Panama Canal, north of the Gatun Lock. 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 ...

Mapping Top of Rock with Seismic Refraction and ERI case study
Industrial Facility, Tennessee An environmental assessment and remediation design project was conducted at a chemical manufacturing facility in eastern Tennessee. As part of the project, GeoView was asked to determine the depth to limestone bedrock underlying the project site and identify any suspected karst features within the upper portion of the limestone stratum. The general geological ...

Geotechnical Geophysics: Seismic refraction and refraction microtremor (ReMi) surveys
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 ...

Passive Seismic Surveying
A new and cost-effective site-assessment tool for the quarrying industry Good quarry design and efficient operation depend upon a ground model that reliably defines the quality, volume and spatial distribution of resource and waste. Most ground models are based on boreholes, sometimes with additional 2D or 3D control provided by ‘traditional’ geophysical surveys such as microgravity, ...

Recognition of karst structure using refraction tomography
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. The studies were carried out on the terrain neighboring to the wall of abandoned ...

Case Study: Granite Rock
The world is changing. Consider the environment: In just a couple of decades, our knowledge of the world around us and how we affect it has caused significant shifts in the way we act. The best example of this lies with our corporate culture, as companies have to consider their impact on the world as well as their overall profitability. Industries that rely on the earth are in a precarious ...
