چکیده انگلیسی
Absolute measurements of soil density using a weight gauge attached to the standard probe of Owsley [D.W. Owsley, Techniques for locating burials, with emphasis on the probe. J. Forensic Sci. 40 (5) (1995) 735-740] provide digital data for operator-independent verification and possible later manipulation. The weight gauge measures insertion pressure that depends on soil density, variations in which may define areas of disturbance. Iterative reconnaissance surveys allow selection of appropriate probe length and weight gauge type in order to obtain maximum sensitivity. In a test case, a probe was used to locate a 50Â cm-wide, 3-year-old fibre optic cable trench in urban circumstances where geophysics would have proven challenging. Subjective surveys using the standard 1Â m probe located the trench; summary digital output from the weight gauge (contoured on site in 1Â h) allowed the original form of the trench to be ascertained. This is a preliminary note: the technique requires testing by parallel measurement, comparison to other (especially geophysical) techniques and in a court of law.
