“…We thus chose to use the WennerSchlumberger array, which is optimal for disturbed surface conditions. This configuration has a good signal-to-noise ratio, but synthetic modelling studies have shown that the spatial resolution of this configuration is relatively poor (compared to, for example dipoleedipole, Schlumberger, half-Wenner and pole-dipole) (Dahlin and Zhou, 2004;Drahor et al, 2008a). During data acquisition, the distances between the potential electrodes were 1, 2 and 3 m, and the "n" factor was varied between 1 and 6.…”

“…Both electrical resistivity tomography (ERT) and resistivity profiling have been widely used in archaeology (Drahor et al, 2005(Drahor et al, , 2008a(Drahor et al, , 2008bDrahor, 2006;Papadopoulos et al, 2006;Astin et al, 2007;Casana et al, 2008, Tsokas et al, 2008.

“…ERT yields more information than conventional resistivity mapping or imaging about depth, true resistivity and the extent of buried archaeological structures. In archaeology, the most commonly used inversion method of ERT is robust inversion (L1 norm) (Wolke and Schwetlick, 1988;Loke et al, 2003;Drahor et al, 2008a). The robust inversion method tends to produce more accurate models for sharp structures; thus, this method is preferred for structures with sharp edges, such as the relics of ancient buildings.…”

“…Ground penetrating radar (GPR) and electrical resistivity tomography (ERT) can be used to trace caves (e.g., Chamberlain et al, 2000;Gibson et al, 2004;ElQady et al, 2005;Valois et al, 2010;Gosar & Čeru, 2016), search for discontinuities in limestone rocks and determine soil depth in buried karst terrains (e.g., Zhou et al, 2000;Harvitch & Valenta, 2011;Hamdan et al, 2012) and determine soil thickness in archaeological sites (see e.g., Griffiths & Barker, 1994;Drahor et al, 2008), mines and caves (Kauffman, 2002). Seismic methods can be used for geological mapping and estimating the depth of soft cover layers (e. Giocoli et al, 2015) and for the detection of caves (e.g., Surányi et al, 2010).…”

Abstract:The deposition of unconsolidated clay sediments in caves, in relation to the buried morphology of the karstic conduit, are important parameters for the study of cave evolution. We introduce the application of an active seismic imaging technique to investigate the clay deposits and bedrock morphology in caves. Seismic traveltime tomography, applied for the first time in cave studies, can assist with the interpretation of cave geomorphology. Utilizing the P-wave velocity contrast between the clay sediments and the surrounding rock mass, we map the buried rock surface and significant sediment interfaces and provide an estimate of the sediment thickness and volume. Our study focuses on the Alepotrypa Cave located in Diros (Peloponnese, Greece), revealing important information for the evolution of the cave. The proposed technique could be applied in caves with significant clay deposits, in order to constrain the clay volume and reconstruct the buried floor shape of the cave. The technique exploits fully the ground morphology and access points in a cave, so it is suitable for a detailed three-dimensional exploration of cave deposits and the underlying cave morphology.seismic traveltime tomography, P-wave velocity, sediment thickness, bedrock surface, Alepotrypa Cave, Greece Polymenakos L., 2017.

“…There is published work on geophysical surveys at Roman forts (Biggins et al, 1999;Biggins and Taylor, 2004;Hopewell et al, 2005;Drahor et al, 2008;Gaffney and Gater, 2003), but none we are aware of on temporary military camps. This paper discusses results of field magnetometry at Septimer Pass, and the complementarity of these geophysical results with the earlier archaeological excavation.…”

The Roman military encampment at the Septimer Pass (near Bivio, Switzerland) was located in 2003 using metal detectors. Dating between 15 BCE and 16 CE, the camp was designed for controlling the Pass, and to enable the movement of Roman troops between Italy and the northern province of Raetia. The 2-ha sized site was delineated by topography, aerial photographs, visible fortification walls and ditches, and the locations of finds. Subsequent trench excavations by the Bavarian Academy of Science were limited to 150 m 2 . Although these excavations provided a better understanding of the construction of the fortification walls, they gave no idea about the overall layout of tents or other buildings. For this study, magnetometry with a cesium-magnetometer in a duo-sensor configuration was used to survey an area of 160x120 m at a sampling interval of 25x50 cm. Some magnetic anomalies suggest geologic lineaments and modern cultural sources. Other anomalies support visual evidence of fortifications, suggest the outline of wooden barracks or contubernia used for military housing, and possibly the locations of watchtowers, pits and fireplaces. The magnetically clean zones between these anomalies correlate with the occurrence of tent nails that were found and cleared by the earlier metal detectorists, suggesting that these areas were primarily used for tents.
