GEOPHYSICAL SURVEY PROJECTS 2020–2021: INVESTIGATIONS IN THE SABINA

Abstract

Considerable investment over the past year, both through private donations and the BSR, has seen a further increase in capacity and expertise with the addition of a laser scanner, Ground-Penetrating Radar (GPR) antennas and a robotic Total Station. The site was initially examined with a magnetometer survey using a Bartington Fluxgate Gradiometer, with data collected at a sample interval of 0.25 m and with parallel traverses at a distance of 0.5 m. Whilst the survey recorded a number of linear negative features on the upper terrace to the south of the pool, the lower terrace revealed a range of both positive and negative anomalies that appeared associated to the complex. See PDF] The composite image of the data interpretation of the major features recorded by both techniques illustrates the dense occupation of the lower terrace with structures recorded alongside the major Roman road (Fig. 2).
