Wessex Archaeology was commissioned by the Anglian Offshore Dredging Association (Hanson Aggregates Marine; Cemex UK Marine; Volker Dredging and Tarmac Marine), coordinated through the British Marine Aggregate Producers Association (BMAPA) and Hanson Aggregates Marine Limited, to provide an interpretative report on the 23 Operational Sampling events undertaken in the East Coast aggregate extraction block and conducted at aggregate wharves between 2015 and 2019, and five events undertaken in 2014 that were not included in the previous report. From the 28 Operational Sampling events undertaken at Frindsbury, Northfleet and Dagenham wharves, 52 lithics and 186 faunal remains have been recovered from approximately 115,000 tonnes of aggregate. Of particular interest was the discovery from Licence Area 240, dredging lane F10 of potentially in situ material of Saalian age with: flint artefacts in near pristine condition; evidence for tool production and debitage; and megafaunal remains. Licence Area 240 remains a 'hot spot' for discovery. With a further 'hot spot' suggested in Licence Area 511 or 228 based on the discovery of finds following the Bacton Beach Nourishment Project. Isolated flint artefacts have been recovered from Licence Area 240, Licence Area 511, and Licence Area 512. Faunal remains have been recovered from Licence Area 240, Licence Area 401/2, Licence Area 511, Licence Area 512, and Licence Area 513.
