Abstract: |
Wessex Archaeology was commissioned by CgMs Consulting Ltd., acting on behalf of McCarthy and Stone Retirement Lifestyles, to undertake a geoarchaeological borehole survey in advance of redevelopment works at the Boat House, Cobden Avenue, Southampton, centred on National Grid Reference (NGR) 443900 114030. Four boreholes were drilled on the Site, on an east-west aligned transect to the south of the Boat House. The lower/earlier part of the sampled sequence, around 6.5-7m below ground level (bgl) consists of a relatively thick terrestrial soil (0.4m) of early Post-glacial date (9150-8790 cal. BC), which developed on an a slight gravel high, which is a likely relic of a Devensian braided channel system.The post-glacial to late Mesolithic alluvial deposits alternated between organic-rich and mineralogenic silts, representing well-vegetated channel margins and more open (although slowmoving) aquatic environments. These changes could be due to either fluctuations in water level or slight channel migration. Above these 3m of alluvial deposits, a thin peat layer (0.08m) at 3.4m bgl was dated to the late Mesolithic (6480-6390 cal. BC). Plant remains and pollen indicate that this formed within a alder carr wetland environment, similar to slightly earlier dated deposits at Testwood Lakes 6 miles to the west. Pollen shows that oak and hazel forests continue to dominate the drier parts of the valley. Sealing the thin late Mesolithic peat were around one metre of soft sticky alluvial deposits with abundant horizontal waterlogged reed remains (Phragmites). |
