Other Areas of Research Archaeometry Group Emeritus Professor: John Weymouth Archaeometry is the study of ways to apply the physical sciences to problems in archaeology. The research at UNL is primarily involved in applying geophysical prospecting methods to archaeological sites. The emphasis is on magnetic surveying, a non-destructive geophysical technique adapted to the unique problems of assessing the subsurface features of archaeological sites. Other methods such as soil resistivity surveying and ground penetrating radar have been studied. These methods depend upon the fact that man's past activities can change the magnetic and electrical resistivity properties of soils. By measuring the magnetic field above a site or the resistivity of the soil with inserted probes, these activities can be revealed as anomalies in mapped data. Various computer processing, image enhancement and model calculation techniques are being used to aid in the interpretation of the data obtained from sites throughout the plains states. Techniques are being developed to use microcomputers to obtain and process magnetometer data in the field. Research is supported by a wide range of state and federal agencies interested in the subsurface contents of prehistoric and historic sites. The work is carried out in close cooperation with archaeologists both in the field and in the analysis stages.
