Area 453 Geophysical Monitoring Report Archaeological Assessment

Geophysical and hydrographic survey data were collected during 2022 as part of the regional monitoring surveys for several marine aggregate extraction areas on behalf of the South Coast Dredging Association (SCDA). Data were collected within pre-defined boundaries covering a minimum of the dredging footprint and a pre-approved buffer. The data were assessed by a qualified and experienced maritime archaeologist to identify any features of potential archaeological significance and undertake a comparison with previously identified features, including within the archaeological baseline assessment undertaken prior to the commencement of dredging. The archaeological assessment of the data from Area 453 is being undertaken to fulfil marine licence monitoring conditions. Conclusions Exclusion zones Following the review of the 2022 dataset, one exclusion zone has been recommended for retention within the extents of the licence area for Area 453and one exclusion zone has been recommended for removal within the extents of the licence area for Are 453. Impacts from dredging activities No additional sites of high or medium potential have been identified in the geophysical and hydrographic data that may have been exposed as a result of dredging operations, suggesting the potential impact of dredging to the historic environment within Area 453 is minimal.
