Wessex Archaeology was commissioned by Hanson Aggregates Marine Limited to undertake a marine geoarchaeological assessment of deposits from the submerged Palaeo-Yare. The work built upon the regional-scale Palaeo-Yare Catchment Assessment (Wessex Archaeology 2013) and supports the Palaeo-Yare catchment 5 year monitoring review (Wessex Archaeology 2020). The study area is located in the southern North Sea, between 10 km and 30 km east of Lowestoft, and comprises Marine Aggregate Licence Areas 212, 240, 242/361, and 401/2. These licence areas are located within the offshore reaches of the Palaeo-Yare valley which contains key deposits from which a large number of Palaeolithic artefacts and faunal remains have been recovered. A total of 184 geotechnical vibrocore logs from five surveys undertaken between 2012 and 2017 were reviewed in order to establish the nature and depth of deposits preserved in each licence area. Deposits were interpreted with reference to the stratigraphic framework defined during the Palaeo-Yare Catchment Assessment. Core photographs and the results from particle distribution analysis were also used to support interpretations. The results of the vibrocore review were compared to the legacy deposit model constructed as part of the Palaeo-Yare Catchment Assessment. Instances where the vibrocore data disagreed with the legacy deposit model were investigated, and where necessary, the deposit model was updated. This assessment was undertaken considering any dredging activity, derived from Electronic Monitoring System (EMS) data, that occurred over the period 2016-2019. Updates to the deposit model were made in Area 240, Area 242/361 and Area 401/2. No changes were required in Area 240. The vibrocore data assessed were largely in agreement with the legacy deposit model, increasing confidence in the original interpretation.
