Resistant ultralaminae in soils [PDF]
Organic Geochemistry, 1996 Observation of a chemically resistant organic residue from maize crop soils by transmission electron microscopy reveals the occurrence of thin laminae with 10-50 nm thickness, similar to resistant, highly aliphatic biopolymers found in kerogens and microbes.

Estimation of the hydraulic parameters of unsaturated samples by electrical resistivity tomography [PDF]
, 2012 In situ and laboratory experiments have shown that electrical resistivity tomography (ERT) is an effective tool to image transient phenomena in soils. However, its application in quantifying soil hydraulic parameters has been limited.

Geophysical monitoring of simulated clandestine graves using electrical and ground-penetrating radar methods: 0-3 years after burial. [PDF]
, 2012 This study provides forensic search teams with systematic geophysical monitoring data over simulated clandestine graves for comparison to active cases. Simulated "wrapped" and "naked" burials were created. Multigeophysical surveys were collected over a 3-
