Abstract
Enhanced interpretation of magnetic survey data using artificial neural networks: a case study from Butrint, southern Albania

Paper describing the results of a detailed magnetometry survey undertaken to investigate Roman settlement upon a floodplain. The study included the use of multilayer perceptron neural networks to further process the magnetic data and derive estimates of feature burial depths, allowing a three-dimensional reconstruction of buried subsurface remains to be made. The neural network approach potentially offers several advantages in terms of efficiency and flexibility over more conventional data inversion techniques. The paper demonstrates how this can lead to an enhanced interpretation of magnetic survey data, which when combined with other geoarchaeological data can provide a clearer picture of settlement evolution within the context of landscape change. The value of this processing technique is also evident within the context of cultural resource management strategies, which potentially restrict more intrusive methods of investigation.
From hypocaust to hyperbola: ground-penetrating radar surveys over mainly Roman...

237 - 246
The paper demonstrates the use of GPR over a variety of mainly Roman remains surveyed recently by English Heritage, ranging in scale from an in situ mosaic pavement threatened by water damage at Bignor Roman villa, West Sussex to an entire, suspected amphitheatre at Richborough Castle, Kent. The influence of site conditions, such as soil conductivity and topography, is also considered and a novel application of principal components analysis is presented to enhance the identification of significant anomalies from data where rapid signal attenuation has occurred. This latter technique considers the correlation of GPR response between adjacent amplitude time-slices in an attempt to isolate the response due to significant buried wall footings from the more cluttered signal of the surrounding clay-rich soil. Where appropriate, URL links are provided to computer animations of the GPR data that may often serve to accentuate subtle variations through the stratigraphy of the site.

The paper describes the advantages of interpreting ground-penetrating radar (GPR) facies in a sequence stratigraphic context. These data have been collected adjacent to the River Shannon at Clonmacnoise Castle in central Ireland and demonstrate that stratigraphy is not necessarily made up of horizontal isochronous surfaces; some reflective surfaces are more important than others in interpretation and that two-dimensional sections must be interpreted with caution. Radar facies analysis and thus sequence stratigraphy can be used to both interpret the sedimentary record in terms of palaeoenvironments as well as identify important (key) surfaces. Bright, continuous surfaces are often found at horizons of palaeoenvironmental change and have distinctive reflector shapes and terminations (or stratal patterns) above and below. Such stratal patterns define and reflect linked fluvial and human environments that have developed and been preserved through the creation of accommodation space. Key surfaces have been identified when sedimentation was altered, thus reflecting a natural or anthropogenic palaeoenvironmental change. In anthropogenically modified or created successions, such as those seen at Clonmacnoise, key surfaces have produced changes in dielectric constants in the sediments that are seen as radar reflections. Natural activity includes lateral migration of point-bars and fluvial onlap. Anthropogenic activity has created accommodation space (the moat), a major sequence boundary and sub-dwelling surface disruption of reflectors. A pre-moat fault can be observed on GPR data that is along strike of a surface scarp to the southwest of Clonmacnoise Castle. The results demonstrate the enhanced interpretive and predictive use of radar facies in sequence stratigraphy.
