Abstract: |
Wessex Archaeology was commissioned by Tarmac Marine Dredging & Van Oord UK Ltd to undertake an archaeological assessment of geophysical survey data as part of the heritage impact monitoring process implemented for aggregate extraction Area 481. The data consisted of sidescan sonar and multibeam data acquired by Gardline Ltd in April and May 2011. The review was to include an assessment of these data in conjunction with the results of the previous desk-based assessment and monitoring report.
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 10 geophysical anomalies were identified within dredging Area 481, and a further 19 geophysical anomalies were identified within the 500m buffer zone. Three shipwrecks were identified, all of which had been previously recorded. One of the shipwrecks is located within Area 481 East and the other two are located in the buffer zone around Area 481 West. The two wrecks within the buffer zone correspond to the charted wreck sites of the Freidig and Heimland, the other is an unidentified shipwreck. The three wrecks were all identified during previous archaeological analysis of geophysical data, and as a result are already subject to exclusion zones.
No new mitigation strategies have been recommended for the area, though it is recommended that the present Archaeological Exclusion Zones remain in place, and that any artefacts recovered during dredging activities are reported using the established BMAPA Protocol for Reporting Finds of Archaeological Interest. |
