A set of seismic track data and accompanying interpretations in XGEO proprietary format. All of the data are project based and are commercially obtained. The interpretations and track data are confidential to the customer. Track data is digitised from maps and charts and combined with digitised seismic profile data interpreted by the geologist. Data are held by project and by user id. All project based datasets are complete but these data are not available to users except where explicit permission has been sought from the data supplier. Seismic track data is usually sampled at every 10th shotpoint. This represents a sampling interval of 250m. The seismic sections will have limits in two way time up to 10 seconds. Data is presented to UKOOA and SEQ standards in terms of data formats. There is a low level of consistency in reflector nomenclature inter-project but totally consistent intra-project.

Digitally held Seabed Sediment, Facies, Bathymetry, Solid and Quaternary offshore geology for certain areas in the UK inshore waters. The storage formats of the data are ESRI and MapInfo but other formats can be supplied.

The British Geological Survey (BGS) holds an archive of multibeam backscatter data from BGS, the Maritime & Coastguard Agency (MCA) and other organisations. The data are stored within the National Geoscience Data Centre (NGDC) as the Marine Environmental Data and Information Network (MEDIN) Data Archive Centre (DAC) for geology and geophysics. The majority of the data were collected and processed for the Maritime and Coastguard Agency (MCA) under the Civil Hydrography Programme (CHP). Backscatter image files for a survey can be downloaded (in GeoTIFF format) using the URL link provided or via the Deposited Data Search (https://webapps.bgs.ac.uk/services/ngdc/accessions/index.html?simpleText=backscatter&subjectList=3159). Backscatter data are useful for seabed characterisation for geological and habitat mapping. BGS works with the DAC for bathymetry data at the United Kingdom Hydrographic Office (UKHO) to archive the backscatter data. View and download the related bathymetry data via the ADMIRALTY Marine Data Portal: https://www.gov.uk/guidance/inspire-portal-and-medin-bathymetry-data-archive-centre.

This is a digital version of the paper based 1:1M scale Offshore Quaternary map, North and South sheets. Customers should be aware that, given the age of the paper based maps, the digital version is not quality assured and BGS can accept no liability for the information held on the digital map. In addition, published 1:250,000 Quaternary maps are available. These contain more detailed subdivision of the Quaternary succession. The original paper based map covers the UK Continental shelf. The paper map is symbolised using lithology and chronology. The lithological boundaries were compiled from the data published in the BGS 1:250,000 Quaternary Geology map series and from revised interpretation of core and borehole data. Core and borehole sites are commonly 5 to 20 km apart, thus the lithological divisions are generalised. The formations and sequences identified by BGS have been grouped into Quaternary age ranges. The geological codes assigned to the digital version of the map have been compiled using the key information held on the paper map. The LEX-ROCK style codes combine the lithology and chronology and have been subject to the standard BGS approval process.

The Quaternary deposits thickness dataset is a digital geological map across the bulk of the UK Continental Shelf (UKCS), for areas up to a water depth of 200m, which shows the thickness of the deposits over bedrock in three categories: <5 m, 5 - 50 m, and >50 m Quaternary cover. These depth bands were picked because they represent the horizons that have impact on offshore infrastructure deployment. The map is derived from (unpublished) BGS 1:1000000 scale Quaternary digital geological mapping. The map was produced in 2014 in collaboration with, and co-funded by, The Crown Estate as part of a wider commissioned project to assess seabed geological constraints on engineering infrastructure across the UKCS. The data are held by the BGS as an ESRI Shapefile.

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.

The Bedrock summary lithologies dataset is digital geological map across the bulk of the UK Continental Shelf (UKCS), for areas up to a water depth of 200 m, which groups the bedrock lithologies (rock types) into classes based on similar engineering geology characteristics. The map is derived from the 1:250 000 scale digital bedrock map of the UKCS (BGS Offshore Bedrock 250k), which is available separately from BGS. The map was produced in 2014 in collaboration with, and co-funded by, The Crown Estate as part of a wider commissioned project to assess seabed geological constraints on engineering infrastructure across the UKCS. The divisions on the map combine the bedrock formations into 8 classes (with several subdivisions) of similar strength and lithological variability, each with a 'Category' title that summarises their main lithological character: Class1 – Igneous; Class 2 - Tertiary Sandstone and Limestone; Class 2.5 - Tertiary Sandstone and Limestone Interbedded; Class 3 - Tertiary Mudstone; Class 4 - Mesozoic Sandstone and Limestone; Class 4.5 - Mesozoic Sandstone and Limestone Interbedded; Class 5 - Mesozoic Mudstone; Class 6 – Chalk; Class 7 – Metamorphic; Class 8 - Palaeozoic Sedimentary. The data are held by the BGS as an ESRI Shapefile.

Reports of work carried out worldwide by the BGS and its precursors. These reports cover a wide range of scientific and technical disciplines and were produced for a variety of purposes. Reports date from about 1950 although there are only a comparatively small number of reports pre 1960. The reports are not published but copies can be provided on demand, in hard copy or pdf format ,subject to any restrictions.

This is a 1:10,000 scale Bedrock geological map for some 800 km2 of the seabed across Weymouth Bay in Dorset. It joins seamlessly to the onshore BGS 1:10,000 scale Digital Geological Mapping (DiGMapGB-10) and therefore shows the coastal geology in detail. It comprises bedrock polygons, faults and limestone bed lines. The map was produced in 2015-16 by digitising against a seamless on- to offshore-shore elevation surface generated from high (1 m bin) resolution bathymetry and coastal Lidar data, collected as part of the Dorset Integrated Seabed Survey (DORIS) project and the Regional Coastal Monitoring Programme of England, made available by the Channel Coastal Observatory under the Open Government Licence. The map can be veiwed using the map viewer at www.bgs.ac.uk/research/marine/doris.html. This map has been produced under the auspices of the Marine Environmental Mapping Programme (MAREMAP), in collaboration between the BGS and the University of Southampton. The map itself should be referred to as: Westhead, R K, Sanderson, D J, Dix, J K. 2016. Bedrock map for the offshore Weymouth Bay area, with seamless coastal joint to BGS onshore (DiGMapGB-10) mapping. Bedrock Geology. 1:10 000 (Marine Environmental Mapping Programme, MAREMAP)
