Geophysical investigations aim at extensive mapping through multi-component geophysical surveying of selected settlements in their greatest extent. Non-destructive geophysical and geological methods will be used to explore larger areas to detect and map existing subsurface architectural remains such as pits, middens, walls, foundations, ditches, hearths, kilns, animal pens, pottery concentrations, burned structures and the stratigraphy of the settlements. To this end, a manifold geophysical approach will be applied in tandem to the study of satellite and aerial photographs, which have been proven to yield important aspects of the prehistoric landscapes, both within the settlements and their environs. Magnetic techniques (using multi-sensor units with cart and DGPS navigation) and Ground Penetrating Radar - GPR will be employed, along with multi-frequency electromagnetic techniques and electrical resistivity techniques.
