Abstract:		 Wessex Archaeology was commissioned by Royal HaskoningDHV to undertake a Stage 4 palaeoenvironmental analysis of borehole BH06 from the site of the proposed Dudgeon Offshore Wind Farm. The Stage 4 work comprised analysis of pollen, foraminifera, ostracod, waterlogged plant and molluscan remains, supported by additional AMS radiocarbon dates. The analysis of borehole BH06 is the first integrated geoarchaeological and palaeoenvironmental analysis of late Glacial and early Holocene sediments from the southern North Sea Basin. The sediments in borehole BH06 include a complex sequence of late quaternary sediments infilling a linear northwest – southeast feature, probably similar to scaphiform glacial valleys recorded in other areas of the southern North Sea basin. The sediments analysed from borehole BH06 cover a period of as much as ca. 4800 years over the transition between the last (Devensian) Ice Age and current (Holocene) warm period (ca. 12700–7900 cal BP). This represents a period of significant climate change, with the abrupt cooling of the Younger Dryas (from ca. 12.9–12.7 ka BP) followed by rapid warming associated with the onset of the Holocene (ca. 11.7 ka BP). The southern North Sea basin saw major transformations, with climate and sea-level rise radically altering the physical and vegetation environments and culminating in the final marine inundation of this landscape by ca. 7900 cal BP. Included in borehole BH06 is 7.5 m of mixed gravelly shelly sand (10.22–2.35 mbSB), bracketed by two radiocarbon dates (8996–8760 and 8105–7931 cal BP) that suggest this deposit may relate to the tsunami event linked with the Storegga submarine landslide ca. 8100 BP.
