A gradiometer survey was carried out by AOC Archaeology Group in 2015 in the northern section of a field to the northwest of Tarradale House to investigate features identified on aerial photos and partially excavated in the 1990s. The survey was undertaken using a Bartington Grad601-2 instrument. The parameters used were suitable for the prospective aims of the survey and in accordance with recommended professional good practice. Data was collected zigzag with a sample reading of 0.25m and traverse interval of 1m within 30m by 30m grid squares. The grids were accurately laid out using survey-grade (cm accurate) GPS equipment (Trimble Geo-XR Rover 6000 series). These readings were downloaded with Grad 601 and processed using Geoplot v.3 software. Several high positive anomalies were detected which could be interpreted as sub‐surface archaeological deposits. An old road was easily detected and some very ephemeral traces of linear features also present that could relate to the features identified on aerial photos. Further work is recommended. <1>
