Wessex Archaeology was commissioned by Marine Ecological Surveys Ltd, on behalf of Westminster Gravels Ltd, to undertake an archaeological review of geophysical survey data as part of the heritage impact monitoring process implemented for aggregate extraction Area 457. The data consisted of sidescan sonar and multibeam bathymetry acquired in 2015 by Bibby HydroMap Ltd. The principal aim of this report is to provide an archaeological monitoring review of known archaeological sites and to assess the area for any anomalies of potential archaeological interest within the Survey Area. This review has identified 25 sites of potential archaeological interest within the Survey Area. Of these, two have been classified as A1 - Anthropogenic origin of archaeological interest, and have been interpreted as wreck sites. Anomaly 7017 is located at the UKHO recorded position of the Stanleigh, a British steam ship sunk in 1941. It is recommended that the existing 100m Archaeological Exclusion Zone around the limits of the wreck is maintained. Anomaly 7023 is at the UKHO recorded position of an unidentified wreck. This position is located some 725m southeast of the licenced Aggregate Area and therefore no Archaeological Exclusion Zone is recommended at this time. It is recommended that any artefacts recovered during dredging activities continue to be reported using the established Marine Aggregate Industry Protocol for Reporting Finds of Archaeological Interest (BMAPA and English Heritage 2005).
