Integration of multiple geophysical datasets to classify archaeological responses
Author(s): Timothy De Smet
North American archaeologists are increasing using multiple near-surface geophysical techniques at archaeological sites to locate features of interest. Examining different physical properties in the subsurface has greatly improved archaeological interpretations; however, these data are often examined in a subjective site specific fashion (notable exceptions are the pioneering work of Kvamme and Ernenwein). This research seeks to quantitatively integrate magnetic gradiometry, frequency-domain electromagnetic-induction (magnetic susceptibility and apparent conductivity), and ground-penetrating radar data from the Magnolia Valley site, Rutherford County, Tennessee. Moreover, this research examines the effects of novel processing techniques (including reduction-to-the-pole, attribute analysis, and Hilbert transform) on the correlation structure of the data in order to improve subsequent classification via supervised and unsupervised learning. A short term goal of these data, or information, fusion techniques is the ability to statistically predict archaeological geophysical responses based upon geophysics and limited archaeological testing. The long term goal of this research program is the stewardship and preservation of the archaeological record, where archaeogeophysics can be used as a standalone method to answer fundamental anthropological research questions about human behavior, social organization, and cultural change through time – without costly and destructive excavation.
