Find & Characterize Unmarked Graves

The Subterra Grey Model P is a mobile soil laboratory for in situ forensic analysis of the soil. The Subterra inserts a probe into the ground to measure the chemical content of the soil by visible and infrared spectroscopy and to probe the compactness of the soil by the probe insertion pressure.

Subterra Grey

Why Choose Subterra Grey?

Subterra Grey Model P detects burials by two means:

  1. Direct detection human remains as the salts of fatty acids.

  2. Indirect detection of the softer soil within the grave excavation.

These effects are long-lasting in the soil, often observable for a century or more after the burial. Immediate results in the field.
