This document describes the outcomes of the implementation of the mitigation measures in place during the dredging of Area 501, which are set out in the archaeological Method Statement (Wessex Archaeology 2017), particularly the archaeological protocol for the reporting of unexpected archaeological discoveries found during dredging activities. Area 501 measures 116.41 square kilometres. A total of 1,482,591 tonnes of aggregate were dredged during dredging operations, however, no archaeology or anthropogenic artefacts were reported through the archaeological protocol. Sixty geophysical anomalies had been identified within Area 501, and 10 of these were within, or very close to, the area that was dredged. Some of these anomalies were identified by magnetometer, and so could still be buried in the seabed, or have been too small to be seen if disturbed during dredging operations. Larger anomalies identified in sidescan sonar and multibeam bathymetry data could have been geological or modern in nature, and in both these cases would not have been reported through the archaeological protocol.
