Abstract:

Wessex Archaeology undertook a Stage 3 archaeological assessment of geotechnical (borehole and vibrocore) samples from the offshore windfarm and export cable route areas of the East Anglia ONE offshore windfarm development. Samples from two boreholes and three vibrocores have been subjected to Stage 3 palaeoenvironmental assessment. The two boreholes were taken from sediments though to be part of the Yarmouth Roads formation, in age equivalent to the Lower and Middle Palaeolithic. Some plant remains and molluscs were recovered. Two vibrocores were thought to be within channel infill sediments, possibly part of the Brown Bank Formation and equivalent to the Upper Palaeolithic. The two sequences appeared to be deposited in different environments and at different periods. The first vibrocore was indicative of deposition in an outer estuarine/shallow marine environment. Plant remains suggest a surrounding pine dominated forest. The earliest part of the Brown Bank Formation is thought to be MIS5e Ipswichian in age and this may be the age of the sediments. The organic sediments assessed within the second vibrocore indicated a small isolated freshwater pool or cut-off channel. Pollen remains indicate a wet fen habitat with open water with a surrounding forest dominated by pine and hazel. The palaeoenvironmental remains suggest an early Holocene date. The assessed sediments from the third vibrocore, thought to relate to the early Holocene period, contained foraminifera and ostracods indicative of deposition in a marine /outer estuarine environment. The sparse pollen remains were indicative of a surrounding woodland of hazel. No palaeogeographic features of archaeological potential were identfied within the study area. However, it is recommended that all geotechnical logs be provided to WA for geoarchaeological assessment to support the geophysical interpretation. Should any deposits of archaeological potential be identified then further work may be required following WA’s standard five stage geoarchaeological assessment procedure.
