  • Wessex Archaeology was commissioned by Historic Scotland to undertake an Undesignated Site Assessment of the site known as the Tobermory Galleon in Tobermory Bay, Mull. The work was undertaken as part of the Contract for Archaeological Services in Relation to the Protection of Wrecks Act (1973). The assessment was carried out in advance of possible further commercial salvage work on the site. Wessex Archaeology conducted a geophysical survey at three sites within Tobermoray Harbour on the 23rd August 2006. The survey was conducted from the S/V Xplorer. A geophysical survey was followed by diver ground-truthing of anomalies was carried out to confirm the position, extent, stability and character of any significant archaeological deposits. The survey showed that part of the wreck and debris fields from both the sinking and subsequent salvage may still exist although the precise nature, extent and position of archaeological deposits associated with the wreck, in particular any surviving coherent ship structure, remained unclear. The survey included single beam echosounder, sub-bottom profiler and sidescan sonar. 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.

  • Wessex Archaeology (WA) was commissioned by English Heritage (EH) to undertake geophysical surveys as part of the project entitled ‘Wrecks on the Seabed: Assessing, Evaluating and Recording’, supported by Round 2 of the Aggregate Levy Sustainability Fund (ALSF). The specific aim of this project was to provide industry, regulators and contractors with guidance on the archaeological assessment, evaluation and recording of wreck sites. ‘Assessment, evaluation and recording’ are taken to include various methods of archaeological investigation that are intended to improve the understanding, preservation and appreciation of the historic environment. Geophysical surveys were conducted over five wreck site areas. This archive relates to the geophysical survey over the Liberator, an unknown wreck, and the submarine U86. Sidescan sonar and magnetometer data were acquired from the vessel Wessex Explorer on the 9th and 12th August 2005 and the multibeam echosounder data were acquired on the 15th and 19th August 2005. 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.

  • 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.

The specific aim of this project was to provide industry, regulators and contractors with guidance on the archaeological assessment, evaluation and recording of wreck sites. ‘Assessment, evaluation and recording’ are taken to include various methods of archaeological investigation that are intended to improve the understanding, preservation and appreciation of the historic environment. Geophysical surveys were conducted over four wreck site areas. This archive relates to the geophysical survey over Hastings Shingle Bank covering the area of the wreck Thomas Lawrence. During the geophysics survey sidescan sonar, single beam echosounder, multibeam echosounder and magnetometer data were acquired. Sidescan sonar, magnetometer and single beam bathymetric surveys were conducted over the Hastings Shingle Bank by Titan Surveys Ltd., aboard the survey vessel Titan Explorer, under supervision from WA staff. These surveys was conducted intermittently during 15 survey days over 47 days between the 17th February – 5th April 2005 with substantial delays due to adverse weather conditions. 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.

  • Wessex Archaeology was commissioned by Historic Scotland to undertake a geophysical survey of the Designated Sites of the Blessing of Burntisland, HMS Campania: designated wreck sites located within the Firth of Forth, Scotland. The work was undertaken as part of the contract for Archaeological Services in Relation to the Protection of Wrecks Act (1973). Wessex Archaeology survey operations took place between 2nd and 6th August 2004. All surveying took place off the survey vessel owned and operated by St Andrews University. This is Crown Copyright Data collected and processed by Wessex Archaeology. The geophysical survey included the use of sidescan sonar and sub bottom profiler. 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.

  • Wessex Archaeology was commissioned by English Heritage to undertake a project entitled ‘Wrecks on the Seabed: Assessment, Evaluation and Recording’. The project was supported by that part of the Aggregate Levy Sustainability Fund (ALSF) distributed by English Heritage. The specific aim of this project was to provide industry, regulators and contractors with guidance on the archaeological assessment, evaluation and recording of wreck sites. ‘Assessment, evaluation and recording’ are taken to include various methods of archaeological investigation that are intended to improve the understanding, preservation and appreciation of the historic environment. The term ‘wreck site’ is taken to include the remains on the seabed of both watercraft and aircraft. As part of a variation of this project Wessex Archaeology was commissioned by English Heritage to undertake a geophysical survey of four designated historic wrecks (A1 submarine, Hazardous, Invincible and Mary Rose) which focussed on the development and testing of methodology for rapid in situ recording using geophysical techniques. The geophysical survey included the use of multibeam echosounder, magnetometer and sub bottom profiler. The survey was undertaken from the 12.5 m Aquastar survey vessel Emu Surveyor belonging to Emu Ltd between 11th and 26th June 2003. 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.

  • This dataset comprises data from Wessex Archaeology surveys which were conducted over various wreck sites between 2003 and 2010. Three of these datasets were acquired in English waters, one in Welsh waters and one in Scottish waters. The geology and geophysics component of the data are archived by British Geological Survey (BGS) in the Marine Environmental data and Information Network (MEDIN) Data Archive Centre (DAC) for Geology and Geophysics. The data include multibeam echosounder, single-beam echosounder, sidescan sonar, sub-bottom profiler, magnetometer, and geological data (vibrocore logs and photos). Data were also provided to other archive centres as appropriate - UKHO (bathymetry), Royal Commission Ancient and Historic Monuments Wales (geophysics), Royal Commission on the Ancient and Historical Monuments of Scotland (geophysics and diving/ROV), Archaeology Data Service (diving/ROV). Although generated for archaeological purposes, these high quality and resolution data are capable of re-use by marine surveyors and scientists from a range of different fields. Data are delivered via the BGS Offshore GeoIndex www.bgs.ac.uk/GeoIndex/offshore.htm and additional data are available on request enquiries@bgs.ac.uk.
