Q What are the Difficulties in Identifying Pipes Buried below the Frostline with GPR? A By Daniel P. Bigman, PhD Permafrost can be a great material to work in with GPR because the chemical structure of ice is non-conductive, which doesn’t diminish the GPR wave’s signal very quickly. Also, ice has a low dielectric permittivity …
Dr. Daniel Bigman received his PhD from the University of Georgia and is an expert in non-invasive subsurface mapping and 3D imaging. His graduate research focused on the applications of near-surface geophysics to archaeological and historical contexts and has since taught at several universities in Georgia. He has collaborated with scholars on innovative research pertaining to ground penetrating radar and damage prevention and has carried out investigations across the United States on archaeological, forensic, and civil engineering projects. The results of these investigations have been published in peer-reviewed academic journals of international reputation and Dr. Bigman was invited by the European Association of Geoscientists and Engineers to lecture in Germany about his research. He is currently an associate editor of FastTIMES, the leading trade magazine in near-surface geophysics, and is on the board of directors of the Environmental and Engineering Geophysical Society.

The popularity of ground penetrating radar in the damage prevention industry has soared in the past decade. Costs have come down, user interfaces have become more approachable, and the recognition that GPR can identify targets that traditional locators cannot have all contributed to this increase in usage. An emerging trend in GPR technology that has …
