For the reconstruction of the Holocene deposition history of the Loosbach valley at Pestenacker, an UNESCO world heritage site of Late Neolithic wetland occupation, 297 direct push colour logs were conducted. We applied the Soil Optical Color Screening Tool (SCOST™, Dakota Technologies, Fargo, USA) for sensing of visible colours. This colour logging tool (CLT) induces white light and records the reflected light from the sediment in the wavelength range of 350-1000 nm. Raster images, numerical results and depth information are computed by the OST-Software (Dakota Technologies, Fargo, USA). The depth resolution depends on the probing velocity and is in this study in cm-scale. All of the 297 soundings were levelled by a Topcon HiPer II DGPS system in cm-resolution.
