Abstract: |
Wessex Archaeology was commissioned by Fugro EMU Ltd. to undertake an archaeological assessment of geophysical survey data as part of the heritage annual monitoring process for aggregate extraction Areas 473 East and Area 474 Central. The data comprised sidescan sonar and multibeam bathymetry data acquired by Fugro EMU Ltd. during September and October 2014.
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 any new anomalies that may be of potential archaeological interest. A total of 15 anomalies were identified in the geophysical data; 12 associated with licence Area 473 East and three with licence Area 474 Central.
Three of the anomalies identified in Area 473 East were given an archaeological rating of an A1 (anthropogenic origin of archaeological interest) and were identified as two wrecks. It is recommended that a 150m exclusion zone around the boundaries of wreck 7004 and 7005 is retained. No exclusion zone is required around wreck 7007 as the wreck lies outside the current licenced area and is not impacted by dredging activities. The remaining anomalies are situated outside of the current aggregate licence area.
Of the three anomalies associated with the survey of Area 474 Central, only anomaly 7013 is situated within the aggregate licence area and should be avoided if possible. However, due to its uncertain nature no exclusion zone is recommended. Further avoidance is recommended in the location of undisturbed area of seabed towards the centre of the active dredging area in line with previous monitoring recommendations.
It is recommended that any artefacts recovered during dredging activities are reported using the established Protocol for Reporting Finds of Archaeological Interest. |
