Abstract:		 Wessex Archaeology was commissioned by the Association of British Ports Southampton Ltd to undertake an archaeological desk-based assessment in advance of the widening and deepening of the existing approach channel that runs from the Port of Southampton out to the Eastern side of the Isle of Wight by the Nab Tower. Data searches were undertaken within a Study Area, including the local Historic Environment Records, The National Monuments Record, The UK Hydrographic Office, The Ministry of Defence and data held within Wessex Archaeology’s library. Wessex Archaeology conducted a geophysical survey of selected proposed dredging areas between 31st March 2008 and 17th April 2008, including echo sounder, sidescan sonar, sub-bottom profiler (boomer) and magnetometer data. Wessex Archaeology also produced a geoarchaeological assessment of existing borehole/vibrocore records in order to assess the potential for submerged prehistoric archaeology. A total of 136 sites and findspots, ranging in date from prehistoric to modern, were recorded within the Study Area. Of these seven are known wrecks recorded by the UKHO and 72 are recorded shipping losses. The rest of the data set consists of findspots or unidentified features. The assessment of the geotechnical and geophysical data identified two sedimentary units of potential archaeological significance: a Pleistocene gravel unit and a Holocene fine-grained sediment unit in which peat layers were identified. These units were identified within the majority of the survey areas. All geophysical anomalies identified in the sidescan sonar and magnetometer data were assessed in terms of their archaeological potential. In all but one of the survey areas anomalies were observed in the data which were of likely anthropogenic origin. No sites of high archaeological significance were observed in the data.
