Reference Library - Supporting Scientific Documents
Subterra Grey stands on a foundation of rigorous research. Our Technical Overview references a broader library of academic documents. For those seeking further information about our products, we offer supporting reference papers. The three most-popular papers are listed with a short description below.
Technical
Overview Paper
This technical packet describes the current version of the Subterra Grey, a field-ready device used in the search for human burials in the shallow subsurface with forensic, police, military, and related applications. This packet describes the underlying technology, equipment, and software, and provides general guidelines for use of the Subterra Grey.

Paper #2
This study explores the use of shallow subsurface soil spectroscopy in two
different contexts: at archaeological habitation sites and at forensic sites where the presence of clandestine human burials is suspected.
Application of In Situ Shallow Subsurface Soil Spectroscopy (S4) to Archaeology and Forensics
Reference
Paper #3
The specific purpose of this study was to establish laboratory detection limits of four potential human decomposition products (leucine, calcium pyrophosphate, oleic acid, and palmitic acid) under a variety of soil conditions and demonstrate their applicability to human burial analogues under field conditions.
Laboratory Detection Limits of Potential Human Decomposition Products Under A Variety of Soil Conditions
Reference
Paper #4
This paper presents the results of an emerging technology for
archaeological prospection that records shallow subsurface optical
spectra of soils and anthropogenic features using a mobile instrument with probes connected by fiber optics to visible and near- infrared spectrometers.
In situ shallow subsurface reflectance spectroscopy of archaeological soils and features: a case-study of two Native American settlement sites in Kansas
