Abstract: |
Wessex Archaeology was commissioned by DONG Energy to undertake a Stage 3 palaeoenvironmental assessment of vibrocore and borehole samples from the site of the proposed Race Bank Offshore Windfarm. The Stage 3 palaeoenvironmental assessment has comprised the palaeoenvironmental assessment of suitable material for recovering floral (plants, charcoal, pollen and diatoms) and faunal (insects, molluscs, ostracods and foraminifera) remains and included radiocarbon dating of samples. The assessment was undertaken upon vibrocore samples from the export cable route and from boreholes in the wind farm area derived from two separate geotechnical surveys undertaken in 2010 and 2013 respectively. The palaeoenvironmental assessment results were mixed. Whilst diatoms were absent from the assessed samples, some good assemblages of molluscs, plant remains, pollen, foraminifera and ostracods were recorded, with the best sequence investigated being from location BH-G01, which is located in the northern part of the proposed wind farm area. Radiocarbon dates obtained from the samples ranged from the Early Mesolithic to the post-medieval periods. The geoarchaeological interpretation from the two geotechnical surveys have also been combined into a deposit model taking into account both the archaeological interpretation of sub-bottom geophysical data from the site and information obtained from the British Geological Survey data. Whilst some interesting Mesolithic sequences have been assessed here, the samples are not deemed to be suitable for further Stage 4 analytical work. Any further analytical work, if warranted, would be undertaken on better (undisturbed) samples from future geotechnical campaigns, if undertaken. No further geotechnical surveys are currently planned. |
