Now, the work aimed at extracting maximum information about archaeological objects using geophysical methods is relevant. The possibilities for this give us the integration of various geophysical methods. In 2018–2019, electrical exploration works were carried out at the archaeological site Ust-Tartas mounds (Western Siberia). The sites for these works were selected based on magnetic survey data. The purpose of the research was to obtain additional information on the parameters of archaeological objects and to compare the possibilities of different geophysical methods. Several different magnetic anomalies were chosen for the studies. Methods of electromagnetic frequency sounding, electrotomography and georadiolocation were used. We were able to refine the length, width, depth of objects, and their configuration. The type of objects studied (burial or pit, settlement complex) is defined. The most informative results, which complement the magnetic survey data, are obtained using the electrotomography method.

Abstract. In Israel occur a giant number of archaeological objects of various age, origin and size. Different kinds of noise complicate geophysical methods employment at archaeological sites. Geodynamical active, multi-layered, and geologically variable surrounding media in many cases damages ancient objects and disturbs their physical properties. This calls to application of different geophysical methods armed by the modern interpretation technology. The main attention is focused on the geophysical methods most frequently applying in Israeli archaeological sites: GPR and high-precise magnetic survey. Other methods (paleomagnetic, resistivity, near-surface seismics, piezoelectric, etc.) are briefly described and reviewed. The number of employed geophysical methodologies is constantly increasing, and now Israeli territory may be considered as a peculiar polygon for various geophysical methods testing. Several examples illustrate effective application of geophysical methods over some typical archaeological remains. The geophysical investigations at archaeological sites in Israel could be tentatively divided on three stages: (1) past (1990), (2) present (1990–2009), and (3) future (2010). The past stage with several archaeoseismic reviews and very limited application of geophysical methods was replaced by the present stage with the violent employment of numerous geophysical techniques. It is supposed that the future stage will be characterized by extensive development of multidiscipline physical-archaeological databases, employment of all possible indicators for 4-D monitoring and ancient sites reconstruction, as well as application of combined geophysical multilevel surveys using remote operated vehicles at low altitudes.

Present Case Study

In the last decades, geophysical methods such as magnetic survey have become a common technique for prospecting archaeological sites. At sub-Saharan archaeological sites, however, magnetic survey and correlated techniques never came into broad use and there are no signs for an immediate change of this situation. This paper examines the magnetic survey undertaken on the Nigerian site of Zilum, a settlement of the Gajiganna Culture (ca 1800-400 BC) located in the Chad Basin and dated to ca 600-400 BC. By means of the present case study, we demonstrate the significance of this particular type of investigation in yielding complementary data for understanding the character of prehistoric settlements. In conclusion, we point out that geophysical methods should play a more important role in modern archaeological field research, as they furnish a class of documentation not achievable by traditional survey and excavation methods, thus creating new perspectives for interpreting the past of African societies.

Tourism Resources

This chapter offers an in-depth analysis of archaeological sites and the value they represent to the field of cultural tourism. Specifically, this chapter discusses the suitable means of studying and managing archaeological sites, which represent tangible examples of cultural tourism. Managed properly, such sites may attract a larger number of visitors and thereby contribute to the region's socioeconomic development. In order to illustrate this line of research, this analysis will focus on one archaeological site in particular, namely the Archaeological Park of Segóbriga in the province of Cuenca, Spain. More specifically, the chapter reviews survey data collected over several years by related public institutions. The findings lend support to several measures that may improve the management of such sites in the context of cultural tourism. The most important of these is the dissemination and promotion of information about the site through WOM and eWOM.

A summary of geophysical applications peculiar to archaeology and magnetic surveying techniques applied by the University of Nebraska to archaeological sites is presented. In contrast to geophysical targets, the size and depth of the features of interest on archaeological sites are from several centimeters to a few meters. Typical features are historic foundations, wells, privies or prehistoric earthen features such as earth house floors, storage pits, or fire hearths. The most commonly used geophysical methods are resistivity, radar, and magnetometry. The program at the University of Nebraska has concentrated on magnetic surveying field methods based on the use of two magnetometers in the difference mode to correct for temporal variations. Data processing used both microcomputers and mainframe computers. Microcomputers are used in the field and near sites to log data and to do preliminary mapping. Mainframe computers are used for further processing and filtering and for producing a variety of graphical representations of the data for an archaeological audience. Case histories presented are from site surveys in North Dakota, Oklahoma, Colorado, and Nebraska.

Purpose. Magnetometry is currently the most popular geophysical technique used for archaeology. The current task for optimization and development of archaeological and geophysical research is to assess the prospects of magnetic exploration within the territory of archaeological sites. In order to develop this subject, the article analyses the experience of archaeological and geophysical works carried out in the Ob-Irtysh interfluves. The research was conducted within the framework of cooperation between the Institute of Archaeology and Ethnography and the Institute of Petroleum Geology and Geophysics, of the Siberian Branch of the Russian Academy of Sciences. Results. Conclusions are made on the basis of comparison of magnetic mapping data, excavation test and measurements of magnetic properties of different soils. The source base includes 30 archaeological sites. There are proposed recommendations for magnetic survey in the presence of interference of various types. The conclusion confirms that the main cause of anomalies over archaeological objects is the ingress of a more magnetic soil in the depths surrounding it. Magnetic survey was found to be effective for archaeological sites, where the contrast of soils and underlying blanket deposits by magnetic susceptibility is no less than 20–30 · 10–5 SI units. It is observed that zones of magnetic properties with high contrast are linked to areas with hills. Conclusion. The achieved results will allow determine the prospects of magnetic survey of archaeological sites of the Ob-Irtysh interfluves. The technique used to estimate magnetic properties is universal, however it will differ between regions due to magnetic properties of the soils. In order to increase the efficiency of archaeological and geophysical works, the geography of such research needs to be expanded.

Reflection Data

Detecting small-size objects is a primary challenge at archaeological sites due to the high degree of heterogeneity present in the near surface. Although high-resolution reflection seismic imaging often delivers the target resolution of the subsurface in different near-surface settings, the standard processing for obtaining an image of the subsurface is not suitable to map local diffractors. This happens because shallow seismic-reflection data are often dominated by strong surface waves which might cover weaker diffractions, and because traditional common-midpoint moveout corrections are only optimal for reflection events. Here, we propose an approach for imaging subsurface objects using masked diffractions. These masked diffractions are firstly revealed by a combination of seismic interferometry and nonstationary adaptive subtraction, and then further enhanced through crosscoherence-based super-virtual interferometry. A diffraction image is then computed by a spatial summation of the revealed diffractions. We use phase-weighted stack to enhance the coherent summation of weak diffraction signals. Using synthetic data, we show that our scheme is robust in locating diffractors from data dominated by strong Love waves. We test our method on field data acquired at an archaeological site. The resulting distribution of shallow diffractors agrees with the location of anomalous objects identified in the Vs model obtained by elastic SH/Love full-waveform inversion using the same field data. The anomalous objects correspond to the position of a suspected burial, also detected in an independent magnetic survey and corings.

In January 1995, the East Texas Archeological Society (ETAS), the U.S. Army Corps of Engineers (COE), the U.S. Forest Service (USFS), and the Texas Historical Commission (THC) agreed to cooperate in a partnership project to inventory and monitor archaeological sites along the Lake Sam Rayburn shoreline. A Letter of Intent (LOI-095-02) was formulated and signed, stating that: the participants are mutually interested in fostering integrated problem solving among heritage resource managers regarding historic preservation issues, with special emphasis on training and information sharing. The Forest Service [and the COE] will gain additional information on the condition and location of archeological sites within its ownership along the shores of Sam Rayburn Reservoir. The participants will gain experience in recording and monitoring of site conditions, gain knowledge concerning the effects of shoreline erosion and looting of sites along the shores of Sam Rayburn Reservoir. Finally, the USFS and the COE will profit from the volunteer labor provided by members of ETAS. This paper reports on inventory and monitoring project activities that took place on September 30, 1995, and October 7, 1995 along the northern end of Lake Sam Rayburn. Elaine P. Sherman was the Project Archeologist, and the work was conducted under ARPA permit no. DACW63-95-0656.

An algorithm for solving the inverse problem for determining the parameters of a buried archaeological object in the form of an elliptical cylinder (as a model of a typical burial or pit) is proposed. The estimation of accuracy of determination of parameters of the buried archaeological objects on the basis of the numerical solution of the inverse problem of magnetic prospecting for synthetic model is carried out. Its implementation included, firstly, the stage of modeling the magnetic field from a synthetic model of the archaeological site at three different heights for different parameters of the grid density and the size of the magnetic survey site and, secondly, the stage of solving the inverse problem from synthetic data at different heights, for different parameters of the magnetic survey and assessing the accuracy of the solution of the inverse problem. It is found that the accuracy of determining the parameters of the anomalous body is more affected by the size of the survey area than the density of the measurement network. There is also a tendency to increase the accuracy of determining parameters when using data of different heights. Approbation of the algorithm for solving the inverse problem on real data of different-altitude magnetic survey over the burial at the archaeological site Tartas-1 showed quite good results. The average error in determining the geometric parameters of the body and its occurrence is ~ 15 %.

Purpose. The Ordynskoe-12 Settlement is an important site for the study of the Late Bronze Age in the south of Western Siberia. The ceramic complex allowed the author to characterize the Ordynsky type archaeological sites. There is a syncretism of the material, including components of other archaeological cultures. According to researchers, the ceramic complex of the site reflects the transition from Fedorovskaya culture to Irmenian culture, while the author identifies items close to ceramics of the Yelovskaya, Karasuk and Irmenian cultures, or a transformed version of Yelovskaya culture at a later stage of its existence. Results. A study of the composition of the clay paste revealed seven recipes. The dominant recipes feature an admixture of crushed stone and organic matter, and chamotte and organic matter, which together account for more than half of the studied samples. A separate group consists of samples mixed with crushed stone. Mixed recipes testify to the coexistence of different populations. Conclusion. The data obtained indicate that this settlement is a multicultural archaeological site. Three archaeological cultures coexisted and interacted in its place – Irmenian, Yelovskaya, and an eastern variant of Pakhomovo culture. Imported vessels indicate contacts with southern cultures, however, importing did not become a mass phenomenon until the transition period from the Bronze Age to the Early Iron Age.
