Aggregate Dredging Area 228 Archaeological Assessment dataset https://portal.medin.org.uk/portal/start.php?tpc=010_ad1880c5-8b1c-39cc-86b5-aa1d86c8c1ae Wessex Archaeology (WA) was commissioned by Volker Dredging Limited (VDL) to undertake an Environmental Impact Assessment in relation to marine heritage and in preparation for a licensing application for aggregate extraction from Area 228. Licence Area 228 is located 12km east of Great Yarmouth. To provide archaeological context for the assessment, a Marine Study Area (MSA) was created within Area 228 contextualised by a 1km buffer around the Licence Area. Historical and archaeological data were combined with seabed and sub-bottom geophysical survey datasets and geotechnical core logs to allow an assessment of the archaeological potential. Following a Stage 1 geotechnical assessment it is clear that the sequences contained within the 25 vibrocores are in many aspects similar to sediments recorded in and studied in adjacent dredging areas. The majority of the area is covered by Devensian and Holocene sands of low potential for prehistoric archaeological receptors, however, it is reiterated that sediments within some of these vibrocores are similar to the sediments within the adjacent Area 240 associated with finds of prehistoric artefacts. There are 9 seabed anomalies of archaeological and possible archaeological interest within the Study Area. One anomaly from within the study area, 7001, has been classified as a possible wreck. Eight other seabed anomalies may relate to unknown wrecks of ships and aircraft. Effective mitigation may be achieved through avoidance of known cultural heritage receptors such as the possible unknown wreck (WA 7001), which may involve exclusion zones. 20120118
