Detection of archaeological crop marks by using satellite QuickBird multispectral imagery

The capability of satellite QuickBird imagery for the identification of archaeological crop marks is herein presented and discussed for two test sites located in the South of Italy. The selected sites, dating back to Middle Ages, were buried under surfaces covered by herbaceous plants characterized by a different phenological status (dry/green) when the satellite data were acquired.     

Archaeological geophysical survey of a Prehistoric Bronze Age site in Cyprus (Alambra <Emphasis Type="Italic">Mouttes</Emphasis>)—applications and limitations

The University of Queensland Alambra Archaeological Mission (UQAAM) conducted a program of geophysical survey and archaeological excavation over four seasons from 2012 to 2016. This program has allowed this study to compile a large array of geophysical data, which has been tested against actual excavation results. By integrating the two forms of archaeological investigation, the UQAAM has been able to identify geophysical ‘signatures’ diagnostic and indicative of internal architectural features relating to the Cypriot Prehistoric Bronze Age (c2400–1750BC). This is the first time internal features have been identified using these techniques on a Middle Bronze Age site in Cyprus. The program has also identified two, and possibly four, areas of domestic settlement. This has yielded results that are of considerable value to cultural heritage managers of the site, which is experiencing development pressures. While identifying several constraints with the geophysical survey for the Prehistoric Bronze Age in Cyprus, the program has demonstrated the efficacy of a combined geophysical survey and excavation approach to sites of the Early-Middle Bronze Age period.     

Cartography of the archaeological surveys taken from an Ikonos stereo-pair: a case study of the territory of Hierapolis in Phrygia (Turkey)

The paper analyses methods and issues connected with the elaboration of Ikonos stereo high-resolution satellite images to create a large-scale cartography for archaeological research. This methodology has been used on an area of the ancient territory of Hierapolis in Phrygia (Turkey), where archaeological surveys, developed by the Italian Archaeological Mission, are in progress. In particular, the study area is situated between the modern villages of Yeniköy and Küçükdereköy, for which neither cartographies suitable for ground surveys nor aerophotogrammetrical covers were available. In this area there are a lot of archaeological remains; in particular, a large Hellenistic and Roman settlement and its necropolises, and also an old Turkish settlement, now destroyed. An Ikonos image was ortho-rectified to obtain a space-map of the entire area. It was used to extract vectorial thematic elements (modern topography, hydrology, archaeological remains and traces, etc.) for the production of maps for archaeological research in the tolerances of a 1:10,000 scale.     

Factors affecting Early Stone Age cut mark cross-sectional size: implications from actualistic butchery trials

Early Stone Age cut marks are byproducts of hominins' tool-assisted animal carcass consumption and provide a potential avenue of inference into the paleoecology of hominin carnivory. If diagnostic cut mark characteristics can be linked to flake and core tool use or the completion of distinct butchery actions, it may be possible to infer ancient tool preferences, reconstruct the consumption of specific muscular tissues, and illuminate landscape-scale stone resource use. Recently, diagnostic morphological criteria including cut mark width and depth have been used to identify marks made by different classes of experimental and archaeological stone tools (Bello, S.M., Parfitt, S.A., Stringer, C., 2009. Quantitative micromorphological analyses of cut marks produced by ancient and modern handaxes. Journal of Archaeological Science 36: 1869–1880; de Juana, S., Galan, A.B., Dominguez-Rodrigo, M., 2010. Taphonomic identification of cut marks made with lithic handaxes: an experimental study. Journal of Archaeological Science 37: 1841–1850; Dominguez-Rodrigo, M., de Juana, S., Galan, A. B., Rodriguez, M., 2009. A new protocol to differentiate trampling marks from butchery cut marks. Journal of Archaeological Science 36: 2643–2654). The work presented here adds to this experimental butchery database by using measurements of cut mark cross-section taken from bone surface molds to investigate how stone tool characteristics including flake versus core tool type, edge angle, and tool weight, influence cut mark width and depth, ultimately testing whether cut mark size is a useful indicator of tool identity. Additionally, these experiments investigate the influence of contextual factors, including butchery action, carcass size, and bone density on cut mark size. An experienced butcher used replicated Oldowan flakes and bifacial core tools in experimental trials that isolated skinning, bulk and scrap muscle defleshing, and element disarticulation cut marks on goat and cow skeletons. This sample explores cut mark traces generated under realistic butchery scenarios and suggests the following results: 1) Core and flake tools were equally efficient at completing all butchery tasks in size 1 and 3 bovid carcasses. 2) Samples of cut mark width and depth produced by core and flake tools were similar and cut marks could not be accurately classified to a known tool type. 3) Skinning and disarticulation activities produced significantly wider and deeper marks than defleshing activities. 4) Cut marks on cows tended to be wider and deeper than those on goats. 5) Cut mark width is negatively correlated with bone density when carcass size and bone portion are taken into consideration. These results suggest that a general quantitative model for inferring tool type or edge characteristics from archaeological cut mark size is not warranted.     

A statistical approach to the archaeological identification of crop processing

Since the processing of crops has a direct effect on the composition of archaeobotanical samples, variation due to crop processing must be filtered out before using samples for the study of crop economy and husbandry. As the archaeological context of plant material does not often provide a reliable basis for the identification of crop processing products and byproducts, this paper presents a method based on the statistical comparison of archaeological samples with ethnographically collected material and on an internal statistical analysis of the archaeological samples themselves. These analyses make use of differences in the categories of weed seeds extracted at each stage of the crop processing sequence and are thus more reliable and more widely applicable than simple calculations of the relative quantities of grain, chaff and weed. Ethnographic and archaeological material from Greece is used to illustrate the method and some of the wider implications of the results are discussed.     

Cultural Niche Construction and Remote Sensing of Ancient Anthropogenic Environmental Change in the North Coast of Peru

Archaeological land use results in the modification of natural environments according to cultural templates and strategies. Deeply entrenched environmental legacies can result from such “niche construction,” influencing subsequent cultures and continuing to resonate in modern ecological function. These changes can be better understood through archaeological remote sensing.Here, I describe spectral responses of densely vegetated sugarcane fields in the Chicama Valley (north coast of Peru) to archaeological features and associated anthropogenic soils (anthrosols). Ongoing satellite remote sensing documents approximately 440 previously unrecorded major archaeological monuments and smaller features within a 310 km² sample of the Chicama Valley The majority of these date to the Moche–Chimu periods (ca. AD 300–1400), with others dating to the Cupisnique–Colonial periods. The newly recorded features are significant for accurately reconstructing the socio-ecological history of anthropogenic environmental change in the region.In addition to advancing analyses of archaeological settlement, these results reveal how prehispanic land use legacies result in persistent anthropogenic niches that can affect modern agricultural potentials. The relationships between anthropogenic features and sugarcane development can be directly evaluated through vegetation indices and physically based image transforms. Phenological response is linked to long-term alterations in soil texture, organic-matter content, and moisture capacity. Past land use thus has a significant impact upon contemporary ecological function, resulting in anthropogenic microenvironments. As sugarcane increasingly is an important industrial crop, these results have the potential to be widely applied to archaeological and agronomic problems, including reconstructions of archaeological landscapes, understanding persistent anthropogenic environments, and mitigating heritage loss while potentially improving precision agriculture.     

The Source Provenance of Bronze Age and Roman pottery from Cyprus

Archaeological interpretations of ancient economies have been strengthened by chemical analyses of ceramics, which provide the clearest evidence for economic activity, and comprise both the objects of exchange and its means. Pottery is often manufactured from local materials, but its compositional diversity typically prevents significant patterns of resource utilization from being identified. Centrally located and positioned on traditional shipping routes, Cyprus maintained ties with and supplied a variety of distinctive ceramic products to the major commercial centres in the eastern Mediterranean throughout Antiquity. We analysed two Cypriot .ne wares and a variety of utilitarian pottery, as well as samples of extant Cypriot clays to determine source provenance. These chemical analyses provide an objective indication of the origins of ancient (Bronze Age and Roman) ceramics manufactured on Cyprus. The distribution of the probable clay sources and the links between pottery style and the material environment also afford a perspective on the spatial organization of large‐scale pottery production on the island. Compositional analysis provides the means to assemble geographies of pottery production and to unravel the interregional system of exchange that operated in Antiquity, but the ability to accomplish these tasks is predicated on systematic analyses of ceramic products and raw materials that are found far beyond the bounds of individual archaeological sites.     

The potential of hyperspectral and multi-spectral imagery to enhance archaeological cropmark detection: a comparative study

Aerial photography has made the single most important contribution to our improved appreciation of the density, diversity and distribution of archaeological sites in Britain since World War Two. This is particularly the case for areas of intensive lowland agriculture where ploughed-out sites are known mainly from marks in the crops growing above them. However, reconnaissance for such cropmarks is not equally effective throughout the lowlands, because of the particular conditions of drier weather, well-drained soils and arable agriculture required before they become visible, and is highly unpredictable.     

Long-term agrarian landscapes in the Troodos foothills,Cyprus

We investigate the temporal and environmental relationships between the terraced hill slopes of Politiko-Koloiokremmos and the adjacent Bronze Age settlement of Politiko-Troullia in foothills of the Troodos Mountains, central Cyprus. Mapping of 102 stone walls on Koloiokremmos is compared with 66 walls farther afield on Cyprus to create a six-part terrace typology. Sherd counts from 174 2-m radius collection circles over approximately 20 ha on Troullia and Koloiokremmos were used to create interpolated sherd density surfaces revealing distinctly different patterns of land use for four major archaeological eras between the Cypriot Bronze Age and Medieval Period. We compared sherd density patterns according to terrace types, length, slope and vegetation cover determined by SAVI (Soil-Adjusted Vegetation Index) from Ikonos and Quickbird satellite imagery.The most robust sherd patterning indicates Prehistoric Bronze Age settlement at Troullia, as confirmed by soil resistivity and excavation, and multi-period land use on Koloiokremmos immediately upslope of the village that may be associated with agricultural terracing. Scattered sherd concentrations indicate later use of this landscape as an agricultural hinterland for the Iron Age city of Tamassos. Sherds and a down slope spread of roof tiles from the Roman through Medieval periods suggest an isolated structure near the crest of Koloiokremmos. Longer terraces correlate with greater vegetation cover and are interpreted as agricultural, while shorter terraces, apparently for erosion control and arboriculture, are significantly related to Prehistoric Bronze Age sherd patterns. Our results suggest that coordinated analysis of archaeological, geographical and remotely sensed environmental data associated with terraced landscapes can be used to infer long-term patterns of agricultural land use.     

Characteristics of Oman's archaeological resource: a preliminary review of management prospects

This paper is a preliminary overview of the main characteristics of the archaeological resource of Oman from a management perspective. It looks at the resource in terms of form, space and time. It covers a pilot statistical analysis of the archaeological data so far input into the proposed National Archaeological Database of Oman (NADO). The main findings of this analysis show that the management of Omani archaeological resource lacks a well‐defined strategic research plan, and that there are large research gaps in many geographical and chronological areas. It also shows that the governmental organisations responsible for the management of the country's archaeological resource are not taking into consideration the potential benefits of archaeological records in their management practices.     

Imaging Radar and Archaeological Survey: An Example from the Gobi Desert of Southern Mongolia

Abstract

The application of spaceborne imaging radar data to archaeological survey in arid regions was investigated at a study area in the Gobi Desert of southern Mongolia. A repertoire of computer enhancement regimens specific to archaeological applications was applied to RADARSAT imagery of the study area to reduce noise, detect lineaments, or otherwise enhance the data. The imagery was then georectified and integrated into a large area mosaic, creating detailed multi-layered image-maps that were used to direct ground exploration. During two field seasons with the Joint Mongolian-Russian-American Archaeological Expedition (JMRAAE) in 1997 and 1998, precise latitude/longitude information was obtained with Global Positioning Satellite (GPS) devices, establishing Ground Control Points with which to further georectify the image-maps. Both navigation and archaeological site selection were enhanced by hydrologic and topographic information in these satellite image-maps. The JMRAAE field team successfully located Palaeolithic cultural artifacts showing little or no surface expression, most often in association with ancient watercourses. The team was able to navigate accurately through the extreme desert terrain using the image-maps and GPS in this otherwise only minimally mapped area, thereby facilitating detailed archaeological reconnaissance and survey.     

Integration of geophysical surveys,ground hyperspectral measurements,aerial and satellite imagery for archaeological prospection of prehistoric sites: the case study of Vésztő-Mágor Tell,Hungary

An integration of geophysical surveys, ground hyperspectral data, aerial photographs and high resolution satellite imagery for supporting archaeological investigations at the multi-component Vészt?-Mágor Tell, located in the southeastern Great Hungarian Plain, is presented in this study. This is one of the first times that all these techniques have been combined and evaluated for retrieving archaeological information. Geophysical explorations, specifically magnetic gradiometry and ground penetrating radar methods, have revealed shallow linear anomalies and curvilinear rings at the Tell. The use of remote sensing images has confirmed the diverse anomalies with respect to geophysics through photointerpretation, radiometric and spatial enhancements. Moreover, several indices from ground hyperspectral data also have revealed stress vegetation anomalies. These integrated results were used to map the main areas of archaeological interest at the Vészt?-Mágor Tell and plan future excavations. It was found that these multiscalar data can be used efficiently for detecting buried archaeological features.     

Methods for the extraction of archaeological features from very high-resolution Ikonos-2 remote sensing imagery,Hisar (southwest Turkey)

Archaeological research in the territory of Sagalassos is a multidisciplinary project covering scientific disciplines traditionally linked to archaeology and also new technologies such as very high-resolution remote sensing with sufficient radiometric and spatial resolution (<2.5 m). This paper focuses on the evaluation of GIS-, pixel- and object-based techniques for automatic extraction of archaeological features from Ikonos-2 satellite imagery, which are then compared to a visual interpretation of ancient structures. The study was carried out on the unexcavated archaeological site of Hisar (southwest Turkey). Although all techniques are able to detect archaeological structures from Ikonos-2 imagery, none of them succeed in extracting features in a unique spectral class. Various landscape elements, including archaeological remains, can be automatically classified when their spectral characteristics are different. However, major difficulties arise when extracting and classifying archaeological features such as wall remnants, which are composed of the same material as the surrounding substrate. Additionally, archaeological structures do not have unique shape or colour characteristics, which can make the extraction more straightforward. In contrast to automatic extraction methods, a simple visual interpretation performs rather well. The methods presented in this paper can be applied with variable success to archaeological structures composed of the same material as the surrounding substrate, which is often the case.     

Ancient DNA confirms a local origin of domesticated chenopod in eastern North America

Domesticated chenopod was an important starchy seed crop in eastern North America before the rise of maize agriculture. Domesticated chenopod first appeared in North America during the fourth millennium B.P., however its wild progenitor and site of domestication remain unresolved. Archaeological evidence suggests a local domestication in the Eastern Woodlands, while morphological similarities with modern Mexican cultivars indicate a possible introduction from Mesoamerica. To distinguish between these two scenarios, we isolate chloroplast DNA (cpDNA) from modern and archaeological North American chenopods sampled from across their geographic range. Our results demonstrate that the chenopod grown in the Eastern Woodlands was locally-derived, indicating that independent domestication events gave rise to the ancient eastern North American and modern Mexican cultivars. These results strengthen the argument for an entirely native pre-maize crop complex with chenopod as a major component.     

‘Order’-ing Excavations: Constitution of Archaeology as Legal Evidence in the Ayodhya Case

This paper examines the case of the court-ordered excavations at Ayodhya to understand the process by which archaeological evidence as expert opinion was reconfigured into judicial evidence in a civil lawsuit. Being an exceptional site of enquiry where two institutions of the Indian state — the High Court of Allahabad and the Archaeological Survey of India — come together, the Ayodhya case allows us to complicate the uses and abuses of archaeology. An examination of the orders and documents related to the excavations and the judgment made by the Allahabad High Court shows the production of archaeological knowledge at Ayodhya as highly mediated. The paper argues that this process is determined by the notions shared by both the institutions about archaeology-as-science and about scientific/archaeological expertise, regulated at each stage through judicial interventions and informed by the role that the Archaeological Survey of India and the archaeology profession has played in the production of a nationalist past in India. The employment of archaeology as legal evidence in the Ayodhya case is contingent upon the masking of these mediating roles.     

A Predictive Map of Compression- Sensitivity of the Dutch Archaeological Soil Archive

Abstract

Weak soils like unconsolidated clay and peat may deform and compress considerably by loading, for example, by sand bodies for roads and railways. Archaeological sites within such easily compressible soil layers may therefore be heavily affected by different kinds of construction works. The vulnerability of archaeological sites to compression is largely dependent on soil properties like lithology, grain-size, and previous loading history. This may therefore differ considerably. Predicting the compression sensitivity is of great value for planners, since they can estimate in which areas in situ protection of archaeological sites may be feasible and where it would require (costly) technical measures or plan adaptations.

As part of the Cultural Heritage Agency’s research programme on construction and archaeology, we prepared predictive maps of the compression sensitivity of the subsurface sediments in the Netherlands for 1 m depth intervals from 0 to 20 m depth.

The maps were constructed using a full 3-D model of the subsurface of the Netherlands.

In combination with the Indicative Map of Archaeological Values (IKAW) that is already available, these maps can be used to better estimate the technical measures needed and costs involved for in situ protection of archaeological sites in the planning phase of construction projects.     

Determining the preservation rating of submerged archaeology in the post-glacial southern North Sea: a first-order geomorphological approach

Abstract

During most of the last glaciation, the southern North Sea floor was exposed and accessible to humans. Archaeological finds are concentrated around Brown Bank, Dogger Bank and the Norfolk Banks, but the Palaeolithic and Mesolithic archaeological potential of these areas is poorly known. Management of submerged archaeological heritage requires knowledge about location (potential) and context, ascribing significance (value) and determining risk. Thus, the preservation potential of primary and secondary archaeological material around these three areas is considered a) in the context of the post-glacial evolution of the southern North Sea and b) regarding natural and anthropogenic processes. A detailed review is followed by original research material describing an approach to assessing preservation potential. In general, low-energy deposits associated with former intertidal, floodplain or lacustrine environments are likely to preserve primary archaeological material, including organic remains, whilst (high-energy) riverine environments are more likely to preserve inorganic secondary archaeological material. The main possible anthropogenic impacts on submerged archaeology result from beam trawling, which may disturb deposits at the seafloor, and aggregate dredging, which may remove secondary deposits. Trawling and aggregate dredging are increasingly contributing to knowledge, through reporting finds through established protocols, and through assisting in funding relevant to multi-disciplinary research.     

PREHISTORIC ANTIGORITE PROCUREMENT IN CYPRUS

The Canadian Palaipaphos Survey Project in the Paphos district of south-western Cyprus investigated extensive areas of the Esouzas, Xero, and Dhiarizos River valleys, locating hundreds of archaeological sites spanning the nine millennia from the aceramic Neolithic period to the recent era (Rupp et al. s1984 and 1986). Antigorite artefacts were recovered from Neolithic, Chalcolithic and Bronze Age settlements. A number of geological sources have been proposed for the material from which these artefacts were manufactured. The results of neutron activation analyses of archaeological and geological specimens suggest that the Troodos ophiolite/Kouris River secondary deposits were the primary source of antigorite for the prehistoric populations of the study area. Extreme care must be taken when analysing antigorite samples to avoid material with grey-black magnetite-rich inclusions. since these have radically different trace element chemistries from the pure antigorite.     

Archaeobotanical inference of Bronze Age land use and land cover in the eastern Mediterranean

Charcoal and charred seeds at five Bronze Age archaeological sites discern ancient land use in the eastern Mediterranean. Seed frequencies of orchard crops, annual cereals and pulses, and wild or weedy plants are used to characterize plant utilization at different archaeological sites on the island of Cyprus, in the Rift Valley of Jordan, and in the Jabbul Plain and along the upper Euphrates River valley in Syria. Seed to charcoal ratios provide proxies to determine the relative usage of dung versus wood for fuel across the ancient Mediterranean landscape. Greater charcoal and lower charred seed values are interpreted to represent a wooded environment, while higher amounts of charred seeds and minimal wood charcoal suggest a much great use of dung as a fuel source. Interestingly, Politiko-Troullia (Cyprus, Cypriot archaeological sites are, by convention, named for the nearest modern village (Politiko), followed by an italicized toponym (Troullia) referring to the plot of land that incorporates the site) has the lowest seed to charcoal ratio, suggesting its residents primarily burned wood and that the landscape surrounding Troullia remained relatively wooded during the Bronze Age. In contrast, villagers at Tell el-Hayyat (Jordan) utilized a mixture of wood and dung, in contrast to Tell Abu en-Ni’aj (Jordan), and especially Umm el-Marra and Tell es-Sweyhat (Syria), where inhabitants relied solely on dung fuel. Comparative analysis and interpretation of seed and charcoal evidence thus illustrates the variety of fuel use strategies necessitated by the dynamic and diverse Bronze Age landscapes of the Eastern Mediterranean.
