Geoarchaeological Survey Methods for Enhanced Decision-Making in ODOT's Project Development Process (PDP)

Geophysical survey methods such as ground penetrating radar, magnetic gradient (magnetometer), and electrical resistivity are the three most commonly used types of geophysical survey equipment that archaeologists use to investigate areas less invasively and less labor-intensively. Geophysical surveys are often cheaper, faster, and less destructive than standard archaeological surveying techniques (i.e. surface collecting and shovel testing). The goal of this project is to become independent in conducting non-invasive geophysical surveys. This research project will include a comparison of three methods of geophysical survey equipment and associated software to determine what instrument or combination of instruments works best in different scenarios. ODOT currently hires consultants on a project-by-project basis to conduct geophysical surveys when needed. Over the past several years, ODOT and the Ohio History Connection (OHC) have spent hundreds of thousands of dollars on contracts to conduct these surveys. Being able to conduct these surveys in-house will save money on projects, expedite project reviews, and better manage impacts to resources. Furthermore, by having the equipment and trained staff readily available, ODOT and OHC will be able to conduct these types of investigations more frequently and fully realize the benefits of this technology.
