Abstract:

The landscapes and archaeological sites of the southern North Sea, drowned in the period 12-6 ky BP, represent an almost unexplored field of research. Published palaeoenvironmental reconstructions are largely speculative, being based on few published sea-level index points and in the absence of detailed physical and chronological surveys. In this paper, we review the post-glacial geochronology for the southern North Sea, which includes 54 radiocarbon ages derived from peat, 17 from molluscs and one known dated artefact. The lack of detailed contextual information for many dated samples means that there remains uncertainty in some elevation data, and thus in the resulting interpreted sea level. The archaeological artefacts are mostly derived deposits and thus are of limited use in palaeoenvironmental reconstruction. Overall, the data are consistent with current models of relative sea-level change back to about 10 ky BP (∼45 m depth) but beyond this, there is very little published data. Much more detailed stratigraphic, microfossil and geochemical analysis is needed to help verify chronological data, help interpret the sedimentary settings in which fossils and artefacts are found, and contribute towards more reliable palaeoenvironmental and archaeological reconstructions of the history of the southern North Sea.
