“…1A and 5A) show a rectangular shape, and especially anomaly number 5A shows a marked contrast to the surrounding material. These features are typical of tombs as described by Papadopoulos et al () and Nero et al (). Since air will not conduct electrical currents, we further expect anomalies marked with “A” to represent intact tombs that means cavities that are still filled with air.…”

“…After investigating the resistivity patterns of intact Mycenaean tombs at Kioupia, we transferred these experiences to other, selected areas of the Olympia‐Area‐Survey‐Project (study sites Epitalio and Dartisa) to verify potential chamber tombs. However, the roofs of Mycenaean chamber tombs are often collapsed and the chambers filled with different types of sediment, accumulated or dumped with irregular geometries (Karkanas et al, ; Nero et al, ). In such cases, the difference in resistivity between the collapsed tomb and the surrounding material will be smaller and the lateral and vertical resistivity gradients will be much smoother so that it might be difficult to detect unknown tombs below the surface.…”

“…Geophysical methods provide valuable non‐invasive tools to detect the near‐surface stratigraphy and subsurface structures such as artifacts and tombs (e.g. Bevan, ; Butler, ; Chen, Tian, Zhao, Wang, & Yang, ; Deiana, Leucci, & Martorana, ; Ellwood, ; Malfitana et al, ; Nero, Aning, Danuor, & Noye, ; Sarris, Kalayci, Moffat, & Manataki, ; Tsokas et al, ; Witten, ).…”

Mycenaean chamber tombs are composed of air-filled burial cavities and, therefore, can be detected by non-invasive geophysical methods. In this study, an electrical resistivity tomography (ERT)-based approach was used to detect graves at three different sites in the area surrounding ancient Olympia. We collected ERT data at the necropolis of Mageiras-Kioupia, where a number of chamber tombs had already been located and partly excavated in order to ground-truth the ERT response for chamber tombs in different states of preservation. Near the village of Epitalio, a preceding archaeological survey discovered remains of a one chamber tomb in mid-slope position of a larger hill. There, we applied the ERT-approach, calibrated at Mageiras-Kioupia, to the tomb and detected ten more tomb candidates at this site. In addition to ERT, we carried out ground penetrating radar (GPR) studies at the Epitalio site. In general GPR, data are highly consistent with ERT results. We were thus able to localize an unknown, most probably Mycenaean cemetery where no systematic archaeological information previously existed. In the third area of investigation, the Dartisa plateau, no potential chamber tomb comparable to the ones excavated and measured at Mageiras-Kioupia and Epitalio were identified.

“…In recent times appropriate geophysical methods have been relied upon for the investigation of the subsurface for potential aquifer zones with various degree of success. The resistivity method can be used to determine more accurately depths to bedrock, map graves, fracture zones which are capable of storing groundwater and preferential groundwater flow pathways (Aning et al, 2013a(Aning et al, , 2013bKnödel et al, 2007;Andrews et al, 2013;Nero et al, 2016). The ERI has been used to prospect for groundwater in all the major geologic formations in Ghana (Sikah et al, 2016;Issah et al, 2018).…”

Lack of access to potable and adequate water is a major problem for sustainable development in northern Ghana. Developing groundwater resource is the best option for safe, reliable, and cost-efficient water supplies to these dispersed communities. In this study, nine 2D ERI profiles were carried out with the Schlumberger array in eight communities underlain by the crystalline basement rocks in the Bole District of the Savannah Region of Ghana. The aim was to delineate the aquifer zones and select points for groundwater extraction. Nine boreholes were drilled from the selected points. The yield was found to vary from 12 to 180 l/min with a depth range of 50 to 70 m. The weathered and fractured zones together with the bedrock topography were clearly marked. It is evident that the 2D electrical resistivity technique is useful tool in determining the availability of groundwater in weathered and fractured crystalline environment.

“…Additionally, the ERT technique has found usage in road construction (Farooq et al, 2012), site characterization for borehole development (Ogungbe et al, 2010) and the detection of groundwater pollution (Uchegbulam & Ayolabi, 2014;Wemegah et al, 2017). Other studies also confirm its ability to map shallow anomalies (Kumar, 2012;Nero et al, 2016) and geological units (faults, fractures and quartzite veins) related to the formation of groundwater systems (Mendoza & Dahlin, 2008). In Ghana, Aning et al (2013aAning et al ( , 2013b used it to map the subsurface resistivity structure of the Bosumtwi impact crater.…”

The discovery of oil in commercial quantity in Ghana has led to increase in infrastructural development to provide the needed services to the oil industry. The siting of these industries requires the characterization of the subsurface to determine its suitability to host these facilities. It is in this line that seismic refraction and geo-electrical surveys were conducted on a site near Takoradi, Ghana that has been planned to host a generator and its appurtenances for the oil industry. The objective of the survey was to provide subsurface information critical for the design of earthing system for the proposed generator plant and its appurtenances. The ABEM SAS4000 Terrameter with the Lund imaging system and a 24-channel ABEM Terraloc MK6 were respectively used for the electrical and seismic refraction data collection. The seismic refraction and resistivity results identify three lithological units namely, dry gravel, sand and silty clay layer, water saturated sand and silty clay layer and granodiorites basement rocks. The first layer has a thickness of 10 m and the second layer with thickness in the range of 5 to 10 m. The lithological classifications as obtained from these results correlate with the drill logs. Electrical grounding will be suitable at a depth of 10 m beneath resistivity profile two at a distance between 32 to 52 m.
