Seabed Prehistory: Gauging the effects of Marine Dredging. Palaeo-Arun. Wessex Archaeology (WA) was commissioned, in April 2003, by the Mineral Industry Research Organisation (MIRO) to undertake the research project 'Seabed Prehistory - gauging the effects of marine aggregate dredging' under the financial support of the Sustainable Land Won and Marine Dredged Aggregate Minerals Programme (SAMP). The Survey Area for this study was chosen as a result of prospecting within the Owers Bank area following consultation with representatives from the marine aggregate industry. It is in the palaeo-Arun area approximately 10km south of Littlehampton, off the coast of West Sussex in the English Channel. Survey work took place between 1st and 18th July 2003 and 27th and 28th September 2003 on the Emu Surveyor and included single-beam echosounder, sub-bottom profiler, multibeam and collection of vibrocores. The geology and geophysics component of the data are archived at British Geological Survey (BGS) MEDIN Data Archive Centre (DAC) for Geology and Geophysics. Data were also provided to other archive centres as appropriate.
