| Abstract: |
Wessex Archaeology Ltd has been commissioned by the Resource Management Association (RMA) to undertake an archaeological assessment of marine geophysical data in view of a pre-dredging monitoring heritage review for aggregate dredging Licence Area 472 and for five corridors intended for sediment monitoring outside the aggregate dredging Licence Area.
The assessed marine geophysical data consisted of 2008 sidescan sonar data covering the aggregate dredging Licence Area 472 in full and the seven sediment monitoring corridors.
This report reviews the sites highlighted during Wessex Archaeology’s 2003 desk-based assessment, suggests modifications, highlights new archaeological sites identified within the limits of the aggregate dredging Licence Area 472 and suggests mitigating measures. A total of eleven sites identified during the 2003 desk-based assessment lie within the limits of the current aggregate dredging Licence Area 472. None of these sites were re-identified in the 2008 dataset due to improved data quality, which aided interpretations, and sediment dynamics, possibly covering some of the anomalies identified in 2003. The assessment of 2008 sidescan sonar resulted in the identification of fifteen new sites of possible archaeological interest, eight within the limits of the licence dredging area and seven along the corridors of sediment monitoring, which extend beyond the licence area and will not be subject to dredging.
On the basis of the likely archaeological resource of the region and the sites identified in the sidescan sonar data, the suggested mitigation is as follows:
• Due to the nature and character of the eight sites identified during this assessment no exclusion zones are proposed. Further investigation might clarify their origin, archaeological significance or even discriminate them as objects of natural or modern origin.
• RMA companies apply the British Marine Aggregate Producers Association Marine Aggregate Dredging Protocol for reporting finds of archaeological interest.
• Appropriate training in the operation of the protocol should be given to vessel and wharf staff through material supplied as part of the Awareness Programme.
• Provision for archaeological involvement in any further benthic and geotechnical investigations in order to assert the potential survival of archaeological material and define the limits of their extent.
• Provision for post-dredging surveys to continue the monitoring of the effect of dredging on known sites and the potential exposure of sites of archaeological interest. |
