In collaboration with K. D. Jones Instrument Corp. and Geophysical Services Inc., we are pleased to
announce that Park Seismic LLC has now extended its scope of MASW services to include field-survey and
equipment-lease options. Since its founding in 2006, Park Seismic LLC has been focusing on the research
and development of software solutions for MASW investigation, in an effort to enhance the precision and
the cost-effectiveness of MASW analyses.  As of January 2018, we now provide full-scale MASW survey
services as well as full-scale package lease services of MASW equipment including hardware and software.  
All previous data-analysis and reporting services will still be available.    

Art Fromm, President and CEO of K. D. Jones Instruments Corp. and Geophysical Services Inc. (formerly
known as Fromm Applied Technology), has conducted near-surface seismic investigation for the past
several decades.  We are confident that together we will make novel contributions in the area of
geotechnical seismic investigations, by providing technical solutions in a rigorous but affordable manner.  
We look forward to working with you together.

    Full service MASW investigations are available for various applications; e.g., wind-turbine site investigation, seismic site characterization
    (Vs30m), soil/bedrock mapping, target detection (voids, weak zones, bedrock valleys), among others.  Contact us here for a free

    Rental packages include MASW seismic equipment and ParkSEIS processing software to perform MASW investigations for projects as short
    as a day and for longer multiple months term leases.  Several packages with preset configurations are available for typical applications.  
    Preconfigured equipment and data-analysis software provided on a computer (Toughbook) simplifies data acquisition and processing.  Brief
    instructions for field assembly and post-acquisition data analysis are also included in each package.

    For worldwide and local geophysical service companies, we provide services in data processing and reporting.  We provide free pre-survey
    consultation to ensure proper field operation.  We often send instructions to the local company to perform the field data acquisition, which
    can help reduce cost overruns, save time, and improve accuracy of results. Any geophysical survey company familiar with seismic
    refraction/reflection surveys should find it easy to transition to conducting MASW surveys with few modification.

    We research and develop MASW data analysis and presentation tools.  The ParkSEIS software, first released on January 2015, is the most
    comprehensive and updated tool for MASW data analysis designed to generate shear-wave velocity (Vs) information in 1-D profile, 2-D
    cross section, and depth slices.  It can also perform Back Scattering Analysis (BSA) of surface waves to detect near-surface anomalies such
    as voids, tunnels, boulders, weak zones, etc.  MASW modeling is also included.  ParkSEIS© (PS) can process seismic data sets from active,
    passive, and (active/passive) combined MASW surveys.  Visit the ParkSEIS website for more information.  Contact for customized software.
