Wessex Archaeology was commissioned by MarineSpace Ltd on behalf of Cemex UK Marine Ltd., Hanson Aggregate Marine Ltd. and Tarmac Marine Dredging Ltd. to undertake an archaeological assessment of geophysical survey data as part of the heritage impact monitoring process implemented for aggregate extraction Area 472. The data consisted of sidescan sonar and multibeam data acquired by Gardline Ltd in September and October 2011 (Gardline 2011). The review was to include an assessment of these data in conjunction with the results of the previous desk-based assessment (WA 2003) and monitoring reports (EMU 2010 and 2011). The overall aim of this report is to provide an archaeological review of the effects of dredging upon known archaeological sites and previously identified geophysical anomalies that may potentially be of archaeological interest; and to assess the areas for new sites and anomalies of potential archaeological interest. In total one geophysical anomaly was identified within dredging Area 472, and a further three geophysical anomalies were identified within the 500m buffer zone. Two of the anomalies corresponded with anomalies identified in previous monitoring reports (EMU 2010 and 2011), while the other two were in the vicinity of such anomalies (EMU 2011). No mitigation strategies have been recommended for the area; though it is recommended that that any artefacts recovered during dredging activities are reported using the established BMAPA Protocol for Reporting Finds of Archaeological Interest (BMAPA & English Heritage 2003).
