  • On the Use of Fluxgate 3-Axis Magnetometers in Archaeology: Application
           with a Multi-sensor Device on the Site of Qasr ‘Allam in the Western
           Desert of Egypt
    • Authors: Bruno Gavazzi; Rozan Alkhatib-Alkontar, Marc Munschy, Frédéric Colin, Catherine Duvette
      Abstract: Fluxgate 3-axis magnetometers are seldom used on archaeological sites due to their lack of precision. Nonetheless, they offer light weight, low power consumption and the ability of compensation of the magnetization of the prospecting device. This study proposes to use calibration and compensation processes developed for space research and aerial measurement to build a multi-sensor and georeferenced device to assess deep and shallow objects for large-scale archaeological investigations in Qasr 'Allam, in a context of heavy sedimentary coverage and uneven surface. The use of the device on the site in combination with potential field transformations of the signal such as the double reduction to the pole and the vertical derivative reveal a vast irrigation system as well as a large religious facility. A comparison with gradiometric measurements shows a resolution as good at least for shallow sources. The precise positioning allows targeted excavations that validate the geophysical interpretations and offer new archaeological information. These discoveries give enough proof to the local authorities to define the area to be protected from the threatening progression of agricultural fields. Copyright © 2016 John Wiley & Sons, Ltd.

  • Reassessing Surface Artefact Scatters. The Integration of
           Artefact-Accurate Fieldwalking with Geophysical Data at Medieval Harbour
           Sites Near Bruges (Belgium)
    • Authors: Jan Trachet; Samuël Delefortrie, Marc Van Meirvenne, Bieke Hillewaert, Wim De Clercq
      Abstract: Archaeological fieldwalking is particularly used to detect sites within a landscape, rather than to assess the internal structure of a site itself. Contributory to this trend is that surface artefact patterns collected by pedestrian field survey are rarely seen as valuable archaeological data for intra-site research. In recent decades, they have been overtaken by other non-invasive prospection methods, which seem to be more efficient and time-effective. This paper aims to reassess fieldwalking as a valuable intra-site prospection method and explores its added value when used in a multidisciplinary framework. The medieval lost harbour site of Monnikerede near Bruges (Belgium) is used as a first test-case. The site was subjected to a grid survey in 1985 and recently acted as the location for an intensive artefact-accurate fieldwalking survey as well as an extensive geophysical survey. Comparing the recent global navigation satellite system (GNSS)-underpinned fieldwalking survey results with a 10 m × 10 m grid survey from 1985, demonstrates the gain in knowledge and detail using the former method. The combination of both fieldwalking and geophysics showed both significant positive and negative relations between surface artefact scatters and subsurface anomalies, hence pointing to the complementary nature and added value of the methods being jointly applied. In addition, the combination of both techniques was tested on a second lost harbour site near Hoeke, to further evaluate the potential of the applied methodology. The results demonstrate that, although the sites have been heavily ploughed for decades, the lateral displacement of artefacts is limited and confined to the original medieval allotment. Finally the integration of surface artefacts with geophysical anomalies enabled to enhance the spatio-temporal interpretation of both sites. Copyright © 2016 John Wiley & Sons, Ltd.

  • Geophysical Research at the Prepoštská Cave and Čertova Pec Cave
           Neanderthal Sites (Western Slovakia)

      Abstract: The sedimentary filling of two Slovak Neanderthal sites – the Prepoštská Cave near Prievidza (Micoquian) and the Čertova Pec Cave near Radošina (Szeletian, Mousterian) was investigated, while archaeological and palaeontological studies have shown these caves are very important sites from the viewpoint of the ancient man settlements. No geophysical research had previously been conducted here, therefore ground penetrating radar (GPR) and electrical resistivity tomography (ERT) geophysical methods were applied in order to expose its depths for future archaeological and palaeontological field campaigns. The GPR survey at the Prepoštská Cave revealed a disrupted zone in the southwest (SW) corner of the investigate area, encapsulated in travertine surrounding the bedrock layer identified at a depth between 0.4 to 2.4 m. This discovered zone is assumed to be an undocumented recent excavation zone. The combined ERT and GPR survey also identified at the Čertova Pec Cave, aside from some main structures (large limestone blocks, loamy-clayey sediment in the central part and debris), intact cave sediments, deposited under the debris filling and large limestone block, located at approximately 2 m depth in the back part of the cave, close to its northeast (NE) entrance. These unconsolidated intact deposits represent the lower part of the Mousterian horizon. Thus, the geophysical survey supported previous hypotheses on the assumed existence of deeper layers with potential archaeological and/or palaeontological content, which have since been spatially defined.

  • Advances in Reconstructing Archaeological Magnetic Signals; an Algorithm
           for Filtering Noise due to the Ploughing Effect
    • Authors: Mariangela Noviello; Marcello Ciminale, Vincenzo Del Gaudio, Leonardo Amoruso
      Abstract: Archaeological remains are very often buried under uneven soil of agricultural fields crossed by rather parallel furrows and ridges. Consequently, ploughing in a magnetic survey might produce a repetitive, quite regular, linear noise in the data, which could impede optimal recovery of the archaeological magnetic anomalies; depending on the acquisition line orientation, this noise may show as an oblique, vertical or horizontal pattern in the magnetic maps.Several studies have tested and verified methods for oblique ploughing minimization, but, to our knowledge, no procedures regarding the vertical and horizontal types of noise have been published.The present research proposes a procedure to filter each type of ploughing effect through an algorithm working in the wavenumber domain. The procedure produces images with a considerable reduction of the noise in any direction, resulting in enhanced visibility and readability of the archaeological anomalies.

  • Under the Park. Recent Geophysical Surveys at Verulamium (St Albans,
           Hertfordshire, UK)
    • Authors: Kris Lockyear; Ellen Shlasko
      Abstract: This paper presents the first results of the geophysical surveys – principally a large scale gradiometer survey – of Verulamium Park, St Albans, Hertfordshire, UK, under which lies approximately half of the Roman city. Verulamium was the third largest Roman city in the province of Britannia – covering some 81 ha – and the largest which is currently available for survey. Approximately 65 ha lies under parkland or pasture. The 30 ha available under the Park was the subject of a magnetometry survey in 2013–2014, along with smaller areas of ground penetrating radar (GPR), earth resistance and magnetic susceptibility. These surveys were undertaken as part of a community archaeology project funded by the Arts and Humanities Research Council (AHRC). The surveys have detected a wide variety of features including stone buildings of varying size and complexity, pottery kilns, roads, pits and ditches. The results so far suggest the town can be divided into an area of largely elite housing, an area characterised by smaller structures and industrial features, and a somewhat enigmatic magnetically quiet area. Challenges in the interpretation of the results are discussed, as are potential solutions and planned future work. Copyright © 2016 John Wiley & Sons, Ltd.

  • Magnetometer Survey at the Newly-discovered Roman City of Auritz/Burguete
           (Navarre). Results and Preliminary Archaeological Interpretation
    • Authors: Ekhine Garcia-Garcia; Juan Mari Mtz. Txoperena, Roger Sala, Arantza Aranburu, Juantxo Agirre-Mauleon
      Abstract: This paper summarizes the principal geophysical results obtained at a recently discovered Roman city at Navarre. Prior to the survey, the extent of the affected areas and the characteristics of the settlement were unknown. The authors describe the field strategy applied and focus their discussion on the archaeological interpretation of the fluxgate gradiometer data. The results allowed for a detailed description of the layout in the main area revealing a city organized along the Roman road, which would have preceded the buildings. On the contrary, the results show important differences in magnetic contrast in the surveyed areas. Whilst the walls of the main area are well resolved, other areas do not show a discernible magnetic contrast even though their existence has been proven by other sources. The origin of these differences is discussed and preliminarily attributed to waterlogging or to differences in the thickness of the archaeological deposits. The magnetic survey, therefore, has shown itself to be a suitable technique for obtaining a preliminary assessment of the archaeological characteristics of the settlement, but cannot be used to definitively assess the affected areas. The results allowed zoning based on the contrast differences that will be used to guide further investigations. Copyright © 2016 John Wiley & Sons, Ltd.

  • From Low Cost UAV Survey to High Resolution Topographic Data: Developing
           our Understanding of a Medieval Outport of Bruges
    • Authors: Jeroen De Reu; Jan Trachet, Pieter Laloo, Wim De Clercq
      Abstract: This paper assesses the application of a consumer-grade unmanned aerial vehicle (UAV) solution for the image-based three-dimensional (3D) reconstruction of a buried Medieval landscape at Monnikerede, a deserted former outport of Bruges, with the archaeological aim to achieve a better characterization of the (micro)topography and ultimately a better understanding of the site. The UAV survey resulted in a highly detailed and accurate 3D model of the terrain, allowing a thorough topographic analysis of the complex archaeological landscape. Application of algorithms to produce an enhanced visualization of the topographic variability led to a sequence of derivatives each highlighting the topography in a different way. Additionally a decorrelation stretch was applied on the collected imagery, thereby generating enhanced orthophotos producing another view on the archaeological landscape. Integrating the (enhanced) orthophoto(s) with the digital surface model (DSM) and derivatives to conduct a thorough analysis of the archaeological landscape resulted in the detection and identification of new archaeological features and the formulation of new insights in the layout of this important Medieval outport.

  • Archaeological Applications of Low-Cost Integrated Sidescan
           Sonar/Single-Beam Echosounder Systems in Irish Inland Waterways
    • Authors: Kieran Westley; Rory Mcneary
      Abstract: Inland waterways, such as rivers and lakes have been foci of human settlement and use for millennia. However, underwater archaeological prospection or survey in these environments is often hindered by poor or no-visibility conditions. While this can be overcome using a range of well-established geophysical techniques, their application in inland waterways seems comparatively less common than in offshore environments. Possible reasons include the logistical challenges of surveying shallow confined, often inaccessible and uncharted waters coupled with a wider lack of awareness of the submerged archaeological potential of inland waterways. This paper demonstrates one method by which the logistical challenge can be circumvented, specifically the use of low-cost acoustic systems which combine a single-beam echo sounder and sidescan sonar. These systems have appeared within the last decade and are smaller and cheaper than their survey-grade counterparts. Although developed for the sport fishing community, as shown here, they can also be used for archaeological purposes. Their effectiveness for archaeological prospection is illustrated via three case studies from lacustrine and riverine settings in Northern Ireland and by reference to object detection and bathymetric mapping. The data presented indicate that the low-cost systems are capable of collecting data that is sufficient for archaeological purposes but they are best suited to shallow confined waters where their disadvantages (limited range and depth of operation, reduced image quality) are minimized.

  • Joined Interpretation of Buried Anomalies from Ground Penetrating Radar
           Data and Endoscopic Tests
    • Authors: Loredana Matera; Raffaele Persico, Nadia Bianco, Gaetano Leopizzi, Giuseppe Leopizzi
      Abstract: This paper presents ground penetrating radar (GPR) results joined with and back-upped by endoscopic tests performed in two churches. The aim of this work is to show how the endoscopic tests can help the interpretation of the achieved GPR images, and this will be shown with respect to two case histories in southern Italy. The usefulness of the endoscopic tests depends on the kind of targets, but is expected to be particularly useful in cases of buried cavities, where information about the volume and the possible past use of the cavity can be retrieved. In the examined cases, the endoscopic tests allowed the presence of three cavities to be established, helping also in the interpretation of their possible nature and use, even if the endoscopic probe was not gyroscopic nor equipped with a laser for the precise measure of the distances.

  • Detection of Buried Roman Wall Remains in Ground-penetrating Radar Data
           using Template Matching
    • Authors: Lieven Verdonck
      Abstract: Whereas in the last decades the acquisition and processing of archaeological ground-penetrating radar (GPR) data have become mature, the interpretation is still challenging. Manual delineation in three dimensions is time consuming, and often the determination of an isosurface value is not straightforward. This paper presents a method designed specifically for the extraction of buried linear features such as wall foundations, based on template matching. First, the three-dimensional (3D) GPR data cube is synthesized into a two-dimensional (2D) slice. To achieve this, an energy slice based on a sufficiently large time window may often be appropriate, although in this study a combination with other attributes, for example based on phase symmetry, made weak anomalies more distinct. In the next step, we compute the 2D normalized cross-correlation of the composite 2D slice and a number of templates with dimensions similar to the walls in the data set. Of the resulting correlation matrices, the highest correlation coefficient is kept for each pixel, if it exceeds a certain threshold. In this way, wall foundations are successfully mapped, but also many false detections are produced. The latter are greatly reduced in number by using a size threshold and discarding isolated features. The remaining regions are enclosed in bounding boxes, which after vertical extrusion can be used as a simplified 3D representation of the wall structures, and for the creation of a filtered isosurface. For the evaluation of our results, a manual interpretation was used. In the 2D case (i.e. when comparing the total area of the automatically mapped structures versus the manually delineated ones), both the detection rate and the correctness were ~77%. Slightly lower rates (~71%) were obtained in the 3D case (i.e. comparing volumes). Our method was applied to the GPR survey of a Roman villa in Kent, UK. Copyright © 2016 John Wiley & Sons, Ltd.

  • Palaeogeographic Reconstruction in the Transition Zone: The Role of
           Geophysical Forward Modelling in Ground Investigation Surveys
    • Authors: Charles R. Bates; Martin R. Bates
      Abstract: Geophysical survey techniques are commonly used as part of studies to reconstruct past geographies in archaeological and palaeoenvironmental landscape investigations onshore and offshore. However, their use across the intertidal zone for constructing contiguous models is far more challenging. In order to enhance the interpretation of the recovered data forward modelling is used here to demonstrate the effective use of a staged approach to site investigation. Examples of data from electrical and electromagnetic techniques have been modelled and tested with ground truth measurements including trial pits, coring and cone penetrometer testing. This combination of forward modelling and testing has proved to be particularly effective at mapping key geological situations of archaeological interest. The approach is demonstrated by reference to varying subsurface sediment types exemplified by two field examples from the UK coast where typical palaeolandscape features, namely incised channels and deeply buried topographies are encountered. These palaeogeographic features were chosen as they have high potential for association with the evidence of past human activity. Copyright © 2016 John Wiley & Sons, Ltd.

  • Geophysical and Archaeological Evidences of Buried Epipalaeolithic,
           Neolithic, Bronze Age and Roman Architecture in West‐Central Syria
    • Authors: Mahjoub Himi; Angel Armendariz, Luis Teira, Jesus González, Juan José Ibáñez, Maya Haïdar‐Boustani, Albert Casas
      Abstract: The study area is one of many important archaeological sites located near the city of Homs in Syria. Here, the existence of archaeological remains was studied using two complementary geophysical methods: ground‐penetrating radar (GPR) and electrical resistivity tomography (ERT). The results provide evidence of localized buried remains and allowed detailed pre‐excavation planning. Furthermore, the later archaeological excavations validated the results obtained from the GPR and ERT surveys. In some areas, the presence of moist clayey soils caused significant attenuation of the radar signal. Conversely, under these circumstances, the contrast in electrical resistivity between natural soil and archaeological targets is enhanced and thus the ERT results identified the archaeological remains.Many two‐dimensional (2D) profiles showed a set of high relative resistivity values depicting well‐defined discontinuous structures within the first 2 m of depth. Nevertheless, their geometrical distribution and shape was much more clearly defined in the depth slice maps generated from the three‐dimensional (3D) blocks. As a result, data analysis provided a high‐resolution image of the subsurface distribution of the electrical resistivity properties of each area surveyed that can easily be interpreted in terms of structures of archaeological interest.

  • Searching for the Antigonea Theatre: A Magnetic Survey in an Ancient
           Epirus City
    • Authors: Antonio Schettino; Dhimiter Çondi, Roberto Perna, Pietro Paolo Pierantoni, Annalisa Ghezzi
      Abstract: We report on two magnetic surveys performed in July and September 2015 at the ancient Hellenistic city of Antigonea, located in southern Albania. The main objective of the two surveys was to find the city theatre and determine possible sites of future excavations. We suggest a new technique for dense collecting of magnetic data along difficult terrains, with minimization of the topographic effect. Evidence of a possible location of the theatre was found along the southern slope of the Jermë hill, just outside the city walls. Other interesting structures indicate the presence of many other buildings in this part of the Antigonea settlement. Copyright © 2016 John Wiley & Sons, Ltd.

  • Capturing the Past for the Future: an Evaluation of the Effect of
           Geometric Scan Deformities on the Performance of Aerial Archival Media in
           Image‐based Modelling Environments
    • Authors: Christopher Sevara
      Abstract: Image‐based modelling (IBM) applications can be used to successfully extract two‐ and three‐dimensional information from historic aerial and satellite imagery for use in archaeological and other landscape‐oriented research. The robust and highly automated nature of these applications can allow for image matching and dense scene reconstruction, even when input images lack information necessary for processing in traditional photogrammetric workflows. However, the overall quality of the content derived from IBM applications can be directly influenced by a number of variables, including the manner in which archival content is digitized. Significant geometric distortion can be induced in the scanning process when using non‐photogrammetric scanning devices, which can have a negative effect on the subsequent processing of scanned imagery and accuracy of derived content such as orthomosaics and digital elevation models (DEMs). While this is a well‐known issue for users of high end photogrammetry packages, the advent of IBM applications has brought the use of photogrammetric‐style techniques to a wider audience who may not be aware of the impact that geometric errors of this nature can have on the quality of derived data products. This issue is demonstrated here using a set of degraded historic World War II (WWII) Allied reconnaissance photographs that have been digitized on both photogrammetric and non‐photogrammetric platforms and subsequently processed in a well‐known IBM application using identical processing parameters. The results are compared to those from a recently collected set of vertical stereopairs and an airborne laser scan derived DEM. Copyright © 2016 John Wiley & Sons, Ltd.

  • Colour to Greyscale Pixels: Re‐seeing Greyscale Archived Aerial
           Photographs and Declassified Satellite CORONA Images Based on Image Fusion
           Techniques
    • Authors: Athos Agapiou; Dimitrios D. Alexakis, Apostolos Sarris, Diofantos G. Hadjimitsis
      Abstract: To date, archived aerial photographs or recently declassified satellite CORONA images have been used to support archaeological research. However the use of such images is limited to the interpretation of greyscale images, which can be improved by image analysis processes including filters, edge detection techniques, etc. This article presents a methodology to improve the interpretation of these images by adding colour from recently acquired satellites or airborne sensors. The methodology followed in this article, is based on the use of pan‐sharpening algorithms which are applied to a set of an archived greyscale image and a recently colour image taken over the same area. These two images are geometrically corrected while their histograms are matched. Then, the two images are merged based on different pan‐sharpening techniques such as Brovey transformation, high pass filters, multiplicative transformation, principal component analysis and wavelet decomposition. The final result is a colour image which can be further studied for interpretation purposes. A coherence image is also calculated since differences due to time might be also observed in the images (e.g. land use changes). The results presented here from different cases studies of Cyprus indicate that the proposed methodology may be applied in any other greyscale archive dataset. From the results is was shown that Brovey and high pass filter transform seem to be able to support better the interpretation of such archive information. Copyright © 2016 John Wiley & Sons, Ltd.

  • Combined Electrical Resistivity Tomography (ERT), Direct‐Push Electrical
           Conductivity (DP‐EC) Logging and Coring – A New Methodological
           Approach in Geoarchaeological Research
    • Authors: Peter Fischer; Tina Wunderlich, Wolfgang Rabbel, Andreas Vött, Timo Willershäuser, Kalliopi Baika, Diamanto Rigakou, Garyfalia Metallinou
      Abstract: Non‐invasive geophysical methods have been increasingly applied in geoarchaeological research commonly showing the need of data calibration based on stratigraphical information deduced from outcrops or sediment cores. In this contribution, a methodological approach combining two‐dimensional (2D) electrical resistivity tomography (ERT) and stratigraphical data based on coring and, for the first time in geoarchaeological research, direct‐push electrical conductivity (DP‐EC) logging is presented and discussed. The approach yields high resolution data based on studies of two different types of archives, the Holsterburg site in central Germany located in a fluvio‐terrestrial zone and the Corfu City site in Greece located in a near‐coastal zone. It is shown that DP‐EC logs trace fluctuations over grain size in high resolution which reflect changes of depositional conditions in the course of time. In addition, constraints from DP‐EC logs in the form of layer interfaces and electrical resistivities were incorporated into the ERT inversion process minimizing the ambiguity of inversion results. It is shown that incorporating regions with certain starting resistivities based on DP‐EC logs exceed the advantage of using layer interfaces alone. It is concluded that in future geoarchaeological and geomorphological studies a combined application of coring, DP‐EC logging and ERT measurements should be considered as a standard approach towards a more comprehensive stratigraphical characterization of the shallow subsurface.

  • Multi‐methodological Geophysical Exploration for the Interpretation of
           the Ancient Landscape of Phaistos (Greece)
    • Authors: Rosa Di Maio; Mauro La Manna, Ester Piegari, Cecilia Mancini, Vladimiro Achilli, Massimo Fabris
      Abstract: Phaistos is one of the main Minoan palatial sites in the Aegean context. The ancient sources and the scarce archaeological records indicate that the city, destroyed by the nearby town of Gorthina during second century bc, underwent also an important post‐palatine phase from alto‐archaic and archaic age to Hellenistic age, still scarcely excavated. Thus, in recent years, new research that integrate different methodologies has been performed to study part of the western Mesara plain, with a special focus on the area around the Phaistos’ hills and the underlying plateau. In this paper, the results of high‐resolution magnetic, electromagnetic, electrical and aerial photogrammetric surveys carried out in an area south of Phaistos site (Haghios Ioannis) are reported. All geophysical and geomatic data are consistent in showing a sharp contrast in soil properties of the northern and southern sectors of the survey area, which could help the paleoenvironmental reconstruction of the large lake developed at the foot of the Phaistos hill during the Minoan age. Furthermore, several deep and shallow anomalies with regular geometric shapes suggest the presence of different types of buried structures. In particular, in the shallowest part of the subsoil, all observed data show elongated structures, whose geometry and physical properties well correlate with the presence of wall remains, and an anomaly feature with a semicircular shape also detected by previous orthophoto interpretation studies.

  • The Use of Geophysical Prospections to Map Ancient Hydraulic Works: The
           Triglio Underground Aqueduct (Apulia, Southern Italy)
    • Authors: Giovanni Leucci; Mario Parise, Mariangela Sammarco, Giuseppe Scardozzi
      Abstract: This paper presents an integrated analysis using ground‐penetrating radar (GPR) and electrical resistivity tomography (ERT) studies to map the Triglio underground aqueduct that in Roman times supplied fresh water to the ancient town of Tarentum, modern Taranto, Apulia region, Italy. The study area includes an expansion project of a nearby limestone quarry where mining activity is related to the production of a steel factory (ILVA). The aim was to develop methods for detection and mapping of the geometry of the underground aqueduct. Seven GPR reflection profiles were acquired across and parallel to the hypothesized extent of the aqueduct, while the ERT method was used to understand the stratigraphy of the area and tie reflections to geological units.Well‐preserved vertical shafts for ventilation and inspection of the ancient underground hydraulic work were investigated and used as models for GPR exploration. The GPR profiles, interpreted using both the trace amplitude analysis and the forward modelling, showed reflection features from the main horizontal tunnel of the ancient aqueduct. The void space within the aqueduct, usually the ceiling–air interface, was discovered and mapped using reflections profiles both parallel to the linear feature, but also crossing it, and differentiated from similar looking geological features.

  • Multi‐technique Geophysical Survey in and around the Hillfort Lossow –
           a Bronze and Iron Age Central Site in Brandenburg, Germany
    • Authors: Burkart Ullrich; Ronald Freibothe, Henning Zoellner, Ines Beilke‐Voigt, Andreas Mehner, Georg Kaufmann
      Abstract: At the hillfort Lossow, integrated geophysical surveys were applied as part of an interdisciplinary research project. The importance of the prehistoric and Slavic site rests on various shafts within the hillfort, which are dated to the Early Iron Age and contain findings of offering processes associated with cult practices. At present more than 60 shafts with a depth of 5 to 7.5 m are known from test trenches and excavations inside the hillfort. In the settlement in front of the hillfort, large‐scale magnetic gradiometer surveys and electrical resistivity mapping were applied to detect new archaeological features, verified by field surveys and targeted excavation. Inside the hillfort, a combination of magnetic gradiometer surveys, electrical resistivity imaging, ground‐penetrating radar, and pulse‐induction metal detection were used to reveal the complexity of structures like archaeological pits, shafts, pit houses and modern disturbances in varying soil types. These measurements resulted in a very complex signal of the geophysical data. We used an integrated approach for the interpretation of data from magnetic gradiometer surveys, pulse‐induction metal detection and ground‐penetrating radar surveys. Thus it became possible to interpret most of the detected anomalies as archaeological features from the Slavic period or modern metal artefacts in the topsoil. The detection of the Iron Age shafts covered by complex settlement structures only became possible using high resolution electrical resistivity tomography and low frequency ground‐penetrating radar.

  • Slingram EMI Devices for Characterizing Resistive Features Using Apparent
           Conductivity Measurements: check of the DualEM‐421S Instrument and Field
           Tests
    • Authors: Michel Dabas; Antoine Anest, Julien Thiesson, Alain Tabbagh
      Abstract: This article addresses the characterization of resistive archaeological targets and near surface structures by electromagnetic induction (EMI). It presents tests achieved with the DualEM‐421S instrument (Dualem Inc., Milton, Canada) in order to be able to quantitatively compare these measurements to the standard technique of direct‐current (d.c.) resistivity. The test was done over the Gallo‐roman site of Vieil‐Evreux in Normandy, France and one‐dimensional (1D) and three‐dimensional (3D) inversions were applied to the data set obtained.We have first investigated the signal‐to‐noise ratio of each of the six DualEM receiver coils both in a static mode and for a quad‐pulled system. The dependence on the roll angle was also measured and it is shown that rotation of DualEM must be taken into account if the roll angle is more than ±10°. Absolute calibration and in‐phase/quadrature (out of phase) component discrimination was checked by measuring the response of a small conductive and non‐magnetic sphere. Several electromagnetic soundings by measuring the instrument response at different heights were done in order to check the quadrature (out‐of‐phase) response of the instrument. Inversions of these electromagnetic soundings were compared to d.c. vertical electric soundings (VESs) over four locations and found in accordance. Several maps using different coil configurations (HCP, VCP, PERP) and different heights were performed and inverted, both for a wide mesh (5 m) and for a finer one (0.5 m). The wide mesh allows a global and rapid description of the surface geology context (continuous d.c. measurements cannot deliver equivalent depth of investigation). The fine mesh conductivity maps clearly show the walls of a fanum (temple) as well as other structures and prove that the DualEM‐421S is able to map correctly archaeological resistive targets. These maps and their interpretations were compared to previous results obtained by d.c. technique. Copyright © 2016 John Wiley & Sons, Ltd.

  • Historical Aerial Photography and Multi‐receiver EMI Soil Sensing,

      Abstract: In spite of an increase in World War I (WWI)‐related excavations in Flanders (Belgium), little is known about the nature and extent of the buried heritage of WWI from research on a landscape scale. This paper examines the combination of historical aerial photographic evidence and geophysical soil sensing. A case study in Comines‐Warneton compares data derived from contemporary WWI aerial photographs with multi‐receiver electromagnetic induction surveys. This comparison provides an understanding of the degree of preservation of trenches, dugouts and other military structures, and illustrates the added value of integrating both techniques in an in‐depth, non‐invasive study of conflict landscapes.
