Abstract

Since its inception as a subsurface imaging technique, the multichannel analysis of surface waves (MASW) seismic method has been used in a variety of environmental and geotechnical applications. One of the more interesting applications is performing subsurface imaging in a beach environment. Although the loose and dry ground surface appears to present a formidable obstruction to the application of MASW for deep imaging, there could be an anonymous unexploited source of energy to make it happen. We look at the possibility that low frequency energy from ocean wave fronts can be introduced into seismic recordings made during MASW surveys along a beach or shoreline. Seismic data from MASW beach and shoreline surveys in Massachusetts will be examined for possible evidence of constructive or destructive interference from energy produced by ocean waves. The possible relationships of MASW survey geometry and the geography of the project settings are also examined. This study aims at evaluating the possible exploitation of ocean energy for deep MASW surveys in beach and shoreline environments.
