Abstract The abstract describing the content of the publication or report |
The Bronze Age site at Caldicot, Monmouthshire was excavated from 1988-1992 during the creation of a recreational lake in the ground of the early 13th to the late 14th century castle (Nayling 1992; Nayling and Caseldine 1997). The excavations uncovered Bronze Age wooden structures, including one of the oldest sewn plank boats in Europe, within a series of intersecting palaeochannels of the River Nedern (Nayling 1992). This study revisits the site to conduct a geophysical survey over the area to the north of the original excavations. Its aim is to investigate the buried archaeology of the sedimented valley floor and the relationship of the archaeology to the palaeochannels and the dryland edge. A range of geophysical prospection techniques were used, including EMI (Electromagnetic Induction), GPR (Ground Penetrating Radar), ERT (Electro Resistivity Tomography) and magnetic gradiometry, along with a coring transect to ground truth the results. The high resistivity and high attenuation of the fine grained sediments within the sequence of intercutting palaeochannels are not ideal for geophysical surveys. However, the choice of low frequency (200MHz) GPR and EMI surveys allowed the EMI and GPR surveys to detect large landscape-scale feature. These included the interface between the alluvium and bedrock, palaeochannel features, and the potential continuation of a wooden post alignment found during the archaeological excavation. | ||
