Direct Push Video Imaging: An Innovation in Prehistoric Paleolandscape Survey

Jeroen Verhegge, Simon Delvoie et Hiep Luong
p. 223-227

Résumé

– Direct push video imaging maps buried prehistoric landscapes in soft geology.

– Subtle subsoil variability is detectable through a combination with CPT-E and EC logs.

– Validation remains crucial pending color calibration- and hardware improvements.

Introduction

Archaeological prospection greatly depends on surveying (buried) paleolandscapes. Invasive survey methods (e.g. test pitting or coring) are widely used but are inefficient for mapping purposes, due to the reliance on direct (recovered) soil or sediment observations, specifically in (deeply) buried landscapes. Non-invasive, mobile (near-surface) geophysical survey methods are all characterized by a trade-off between the depth of investigation and the resolution of detectable paleolandscape features. Direct-push sensing is used less frequently but is a compromise between both approaches, due to its rapid, continuous and in-situ data recording as a sensor is pushed down into the soil profile. Therefore, the target discrimination potential is independent of the burial depth, but dependent on the horizontal extent of the target instead. In addition, direct push geophysical data provide an efficient means to constrain models of near-surface geophysical data (e.g. Wunderlich et...
