Subsequent work

The Area 240 project was complete by March 2011 and the results of the project synthesised into a final project report. However, work on the palaeogeography of the region has since continued. 

Following the conclusion of the Area 240 project discussions continued with Hanson Aggregate Marine Limited regarding the remaining potential for artefacts in Area 240. Questions remained over the extent of the archaeological material, particularly the flint artefacts.
 
In 2011 Wessex Archaeology were commissioned by Hanson Aggregate Marine Limited to undertake a programme of archaeological monitoring of aggregate dredging activity on board a dredging vessel and at the receiving wharf at SBV Flushing. The project trialled the method of sampling large volume of sediment for archaeology, using standard aggregate dredging equipment. The recovered archaeology helped to evaluate the distribution, character, quality and preservation of Palaeolithic artefacts within Area 240.
 
In 2012 Wessex Archaeology was commissioned by the British Marine Aggregate Producers Association on behalf of The Crown Estate, CEMEX UK Marine Limited, Hanson Aggregates Marine Limited, Tarmac Marine Dredging Limited and Volker Dredging Limited (the East Coast aggregate block licensees), to conduct an assessment of the Palaeo-Yare catchment area, East Anglia. The aim of the project was to map the extent  and survival of the specific sediment units from which a large number of flint artefacts and faunal remains were recovered in Area 240. 
 
Approximately 2,500 line kilometres of sub-bottom profiler data (from 22 surveys) and 1,171 vibrocore logs (from 43 separate surveys acquired between 1988 and 2011), were reviewed. The majority of these logs were from sampling originally undertaken by the marine aggregate industry. Additionally, approximately 400 onshore borehole logs (supplied by BGS) were reviewed, providing further context.
