Summary

Recent Historic England (HE) projects identified the need for a greater appreciation of the Pleistocene submerged landscapes around the coast of England (Westley et al. 2013; Sturt et al. 2015). This type of research is essential in order to move towards a coherent understanding of the relationship between the currently terrestrial fragments of Palaeolithic landscapes and those that have been obscured by Holocene sea-level rise. As a preliminary stage in the testing of this type of research, this project aimed to demonstrate the value of derived animal bones for providing targeted locations of submerged Pleistocene deposits. This was a three phase process: the first of which involved establishing the zone of archaeological interest as shown by the trawlerderived faunal material, which was then refined using swath data acquired previous to this project. The second phase required the collection of further geophysical data, immediately prior to the dives. This included side scan sonar and sub-bottom data in order to further direct the dive sites and to assess any changes since the original swath survey. Finally, diver groundtruthing was carried out to search for faunal material and to recover short cores for analysis of seabed sediments. This was crucial in order to gain a better understanding of the context and taphonomic history of the specimens and of the now-submerged landscapes in this part of the southern North Sea. Furthermore, as originally identified through discussions with the local trawling community, this project aimed to develop and extend these relationships.
