Ground-Penetrating Radar (GPR) surveys can enhance the quantity and quality of information, when applied to archaeological prospection. The potential of the GPR method lies in its relevance to a wide range of site conditions and the complementary nature of the data in comparison with other geophysical methods.
The Aegyssus archaeological site is located on the Monument Hill, in the north-eastern section of Tulcea, and was built at the end of the 4th century B.C. Its name, of celtic origin, derived from the legendary founder, Caspios Aegyssos. At the beginning of 2nd century, the town was included in the Danubian limes (boundary), then, starting with the 3rd century, it became an important military headquarters. The 6th century finds it as an episcopal residence, after which, urban life ceased to exist. The Halmyris archaeological site represents an ancient roman fortress located in Murighiol commune (Tulcea County). It has been occupied since the 4th century B.C. by the dacians, later becoming an important roman transit center and a port for roman fleets on the Danube. Archaeological excavations in 1981 demonstrated the existence of a continuity of life spanning from the 6th century B.C. to the 6th century A.D. The two archaeological sites mentioned above are related to a unique chronological range between late antiquity and the early medieval period (from the 4th century A.D. to the 7th century A.D). This paper demonstrates the effectiveness of GPR over the indicated sites characterized by differences in soil conditions and hypothesized archaeological features (Viberg et al., 2011). With this method a high-resolution data acquisition was adopted with the aim of reconstructing the location, depth and shape of the archaeological structures in the selected areas. Signal processing and the time-slice represenĀ¬tation technique were used for the analysis of the collected data (Gates and Armistead, 1974). A total of 6 perimeters were surveyed with a 250 MHz antenna aiming in identifying geological and archaeological anomalies in order to assist archaeologists in an excavation program. The GPR results indicated geophysical anomalies characterized by hyperbolic reflections (Tsoflias et al., 2004). These anomalies were confirmed by the excavation of 575 20th International Multidisciplinary Scientific GeoConference SGEM 2020 test units, allowing the identification anthropogenic features such as an ancient terracotta pipe, wall foundations, remnants of civil structures and several objects and artifacts (numerous amphorae, wooden objects and other household objects). Archaeological excavations and interpretations were conducted systematically after completing the geophysical surveys (2019) and confirmed the location and shape of most of the individualized structures (Keller, 1966). The purpose of this paper is to demonstrate the accuracy with which GPR data can be matched to excavation data and the improvement it offers in target definition. |
