PROMPT NON-INVASIVE INVESTIGATION OF

ARCHAEOLOGICAL REMAINS IN ISRAEL

Geophysical investigations (magnetic, resistivity and self-potential methods, ground penetration radar, very low frequency method and some others) are widely used for the investigation of archaeological remains in the world. The territory of Israel, in spite of comparatively small dimensions, is very attractive for archaeologists taking into account its dramatic ancient and Biblical history. According to a rough estimation of some Israeli archaeologists, the total number of archaeological sites on Israeli territory may reach 20,000 (including undiscovered sites). Geophysical methods are successfully applied to archaeology, as there are rapid, effective and non-invasive tool for revealing a broad range of various targets: buried walls, columns, foundations, water pipe systems and high temperature features (kilns, furnaces, ovens). Geophysical surveys provide a ground plan of cultural remains before excavations or may be even used instead of excavations. Generally speaking, all road and plant construction, selection of areas for various engineering and agricultural aims should be accompanied by detailed geophysical (first of all, magnetic) investigations. Such investigations should help estimate the possible archaeological significance of the area under study. Rapid (first results may be obtained during a few hours - several days) and reliable interpretation of geophysical data provide protection of archaeological remains from unpremeditated destruction.

The most significant disturbing factors by interpretation of geophysical anomalies are oblique polarization, complex geological structure (presence of a variety of anomalous bodies) of investigated site, disturbing effect of rugged topography as well as influence of modern iron-containing objects. The nonconventional procedures developed by the authors are intended for application in such complicated environments and include elimination of noise from various sources, selection of "useful" anomalies against the noise background, qualitative and quantitative interpretation of anomalies and 2.5D and 3-D physical-geological modeling (see list of References). Effective integration of these procedures with other interpretation methods allowed to localize rapidly tens of archaeological remains and protect them from unpremeditated destruction.

Unfortunately, these investigations are performing only on an enthusiasm of the authors of the report, field investigator Ph.D. student S. Itkis (Ben Gurion University) and some volunteers. Our poor geophysical equipment is wearied out and its replacement is necessary. Additionally, by many reasons we have not a possibility to cooperate in time with all archaeological organizations, which often invite the low-qualified executors. In Israel, contrary to the usual practice of the developed countries with a rich archaeological heritage, did not create the special geophysical service for providing such investigations. Such an Inter-University Center supplied by the modern geophysical equipment and not large budget may perform and control all geophysical investigations at Israeli (partially, it is possible, in surrounding regions) archaeological sites.
