The Department of Earth & Environmental Sciences is pleased to present, “The Role and Applications of Resistivity, Magnetometry, and Ground Penetration Radar Geophysical Methods to Archaeology” by Kareem Kareem.
Geophysical surveys in archaeology offer quick and reliable subsurface mapping and detection of buried objects by using a number of different methods. The commonly used technique to exploring cultural heritage and artifacts are resistivity, magnetometry, and ground penetrating radar (GPR). Although other geophysical surveys contribute to archaeological applications, the three aforementioned methods are increasing in credibility in their use during archaeological projects. The three methods also provide excellent resolution of many types of archaeological feature and are capable of operating under a wide range of conditions of very large areas. Each specific archaeological site can be assigned its appropriate geophysical technique by professional geophysics with experience in archaeology and geology. Consequently, interpretation that renders clear results is necessary to making the right decision for an excavation location. The use of geophysical methods is ideal because it is a non-invasive way that plays a significant role in minimizing costs and risks: the methods enact this minimization by providing appropriate tools for the preliminary investigation of archaeological sites. Despite the use of a single geophysical survey, techniques can delimitate the archaeological site and/or depth of artifacts; however, integrating data sets from different geophysical surveys can also achieve a more reliable and accurate determination to locate, describe or image cultural remains in a non-destructive way and allow imagining archaeological projects in a different way.
The geophysical survey can provide images, map, and cross section as additional information about cultural heritage that could not be observed from the air or the ground through conventional ways. Thus, geophysical survey can significantly contribute to better mapping, excavation, preservation of ancient material culture, test hypotheses concerning about past cultures, and provide a more thorough understanding of the geophysical methods to archaeological study.
