Geotechnical Engineering Seminar
Friday 22 September 2017, 12:00 - 13:00
Contact Jakob Walter, E.I.T., Graduate Research Assistant, Geotechnical Engineering

Please join us on Friday, September 22nd for the weekly Geotechnical Engineering Seminar from Noon to 1 PM in ECJ 1.318. This week’s speaker is Antony Martin, the technical director of GEOVision, which is a geophysical services company. The presentation is entitled: Application of Surface Geophysical Techniques to Near-Surface Site Characterization. A short bio may be found below.  Also, a pizza lunch will be provided.

 Abstract:

Surface geophysical techniques have a wide range of applications to engineering, environmental and groundwater investigations. These techniques include the seismic refraction and reflection, active and passive surface wave, gravity, magnetic, electrical resistivity, electromagnetic, and ground penetrating radar methods. Geophysical surveys are routinely conducted during engineering investigations to map subsurface geologic conditions (e.g. depth to bedrock, faults) and determine engineering properties of soil and rock (e.g. rock rippability, shear wave velocity). As part of environmental investigations, geophysical techniques are often used to locate and delineate potential sources of contamination (e.g. landfills, disposal pits and trenches, tanks, leachfields, abandoned oil wells, mud pits), map certain types of soil and groundwater contaminants, and characterize geologic features which control the migration of contaminants. Common groundwater related applications of geophysics include characterizing groundwater basins and aquifers. This presentation will include examples and case histories demonstrating the successful application of surface geophysical techniques to near surface site characterization in support of engineering, environmental, and groundwater investigations. 

Bio: 

Mr. Martin is the Vice President and Technical Director of GEOVision, Inc., a near surface geophysical services company in Southern California. Mr. Martin has a B.Sc. and M.S. in Geophysics and has been conducting geophysical investigations in support of environmental, engineering and ground water investigations for 30 years.
