Ground Penetrating Radar

Ground Penetrating Radar (GPR) is another tool OSI utilizes for characterization of subbottom conditions.  This device uses electromagnetic signals (as opposed to acoustic pulses) to penetrate the bottom and “image” underground features.  The GPR is typically employed on land and used for high resolution, moderate penetration applications such as buried utility searches and shallow geophysical assessment.  While OSI has provided land-based GPR services, the instrument is most often employed by OSI in utility searches and geophysical assessment in shallow depth, freshwater settings.  Under the right conditions the GPR has the potential for improved resolution as compared to traditional acoustic subbottom profiling methods such as Chirp and Boomer.
