Rigorous field assessment in different soil types and climates comparing simulated graves with pig remains and human remains are needed to assess the capabilities and limitations of electrical resistivity tomography (ERT) as a tool to search for unmarked graves. Our study assesses the ERT signals from graves with pig and human remains in a cold, humid continental climate with sandy soils. Two sets of three experimental graves were established: the first set consisted of two graves containing human remains and an empty grave serving as a control, while the second set consisted of two graves with pig remains and a second empty grave.

- The project investigates the effectiveness of ground-penetrating radar (GPR) in locating unmarked graves, comparing signals from both pig and human remains.
- Human, pig, and control graves were monitored for 17 months using a GPR system, revealing specific radar patterns associated with remains.
- The study identifies five key radar signature classes for graves, aiding in the interpretation of GPR data in future investigations and enhancing communication within the scientific community.
