“…Magnetic Susceptibility (MS) has also been used successfully in naturally aggrading environments including the Tuxla Mountains of Veracruz (Venter et al., ). GPR and MS have also been highly useful in urbanized or urbanizing landscapes, both ancient and modern – essentially anthropogenically aggrading contexts (Arciniega‐Ceballos et al., ; Chávez et al., , ). In environments such as alluvial wetlands of Veracruz where hard stone was infrequently used, gridded augering programs have proven necessary to map subsurface sites (Wendt, ).…”

Geoarchaeological Investigations in Mesoamerica Move into the 21st Century: A Review

Over the past thirty years, geoarchaeology has moved from the fringe to mainstream status within Mesoamerican archaeological investigations. This review focuses on works published since the year 2000. Five themes are identified as central to recent studies: (1) the correlation of environmental change and cultural history; (2) anthropogenic environmental impacts; (3) ancient land cover, land use, and diet; (4) archaeological prospection; and (5) provenance studies. These themes are often interwoven in the application of complex systems approaches that allow scientists to more accurately model the intricacies of ancient human-environment interactions.

A high-resolution, ground-penetrating radar (GPR) investigation was performed on existing commercial shop premises within The Rows, Chester, UK to detect near-surface features, including a suspected Medieval undercroft (cellar), the location of which was unknown. GPR 2D profiles were acquired on a 0.5 m square grid-pattern both within the premises and on an exterior, Medieval raised walkway. Multi-frequency (250, 500 and 800 MHz dominant frequency) repeat-surveys were acquired in selected areas over the grid to resolve progressively deeper near-surface structures and used to generate 500 and 800 MHz horizontal 'time-slices'.Floor-supporting wooden beams with steel supports on the exterior walkway, the Medieval undercroft, associated passageways and a hitherto unexpected access trap-door were all successfully located. The undercroft was found to be air-filled. Three near-surface rectangular areas were identified and found not to be associated with the undercroft; these were interpreted to represent heterogeneous, rubble back-fill. Separate, isolated, raised areas were also identified ~1.5 m below present floor level; these were interpreted as relict brick column supports from a long-demolished, Roman building. GPR data acquired on the exterior raised walkway also found evidence for relict support structures from a former shopfront.All of the targeted anomalies were intrusively investigated and provided positive confirmation of the geophysical interpretations. Archaeological investigations of trial pits confirmed the site's varied history and depth to bedrock. GPR was therefore effective in this study to locate and characterize the modern, Medieval and Roman features without extensive intrusive investigation, whilst causing minimal disruption to commercial operations. These results demonstrate the effectiveness of carefully acquired and processed, high-resolution, closely-spaced GPR survey data in near-surface characterization for geotechnical investigations. GPR investigations to characterize Medieval and Roman foundations under existing shop premises: a case study from Chester, Cheshire, UKpied through Anglo-Saxon, Norman and Medieval times, to the present day. The Roman occupation left a lasting legacy: parts of the fortress walls and entrance gate sites were preserved and Medieval churches were built directly onto previous Roman building foundations (Lewis and Thacker 2003). In Medieval times, Chester was of strategic and economic importance, due to both the development of the port and its border position. During this time, construction was influenced by the major relict Roman fortress plan and structures; Lewis and Thacker (2003) suggested that 'The Rows' were created as a consequence of the location and availability of relict material in relation to Chester's varied topography. These unique structures are still present today, comprising a series of interconnected frontages, forming multi-level, raised walkways through commercial properties of various building dates and architectural styles (Fig. 2).

“…These methods focus on the identification of variation in certain physical properties of buried sediments that can be measured from the ground surface (Linford, ). Buried archaeological features that possess physical properties different from the surrounding soil are potentially detectable (Scollar et al ., ; Hesse et al ., ; Stierman and Brady, ; Chávez et al ., , ; Bevan and Roosevelt, ).…”

Results of electrical resistivity surveying and pseudo-three-dimensional tomographic imaging at the 15 ha Pre-Hispanic archaeological site of Sitio Drago, Isla Colon, Bocas del Toro province, Panama are presented. The site was occupied between AD 690-1410 and represents the largest known nucleated settlement in the province. A low mound in the centre of the site was selected for intensive electrical surveying in order to locate buried archaeological features. A series of surveys were conducted, including electrical resistivity mapping and pseudo-three-dimensional tomographic imaging. The results revealed a group of resistivity anomalies associated with buried archaeological features. Based on these results, archaeological excavations were targeted that uncovered a cluster of coral slab structures, each containing human remains.
