BGS has drilled almost 600 boreholes to prove seismic interpretations of the marine Quaternary geology and bedrock from the UK Continental Shelf (UKCS). The collection also includes additional third party data and has assisted in the creation of BGS Marine Geology Maps. The boreholes penetrate beneath the sea bed to depths ranging from about 10m to over 300m depending on the target depth or technical problems associated with drilling the borehole. The data includes descriptive geological core logs and data which has been captured from these and in some cases natural gamma logs. A variety of analyses has been conducted on the core material such as Particle Size Analysis, micropalaeontological, geotechnical, palaeomagnetic and age dating. Core material are managed as part of the BGS Materials collection and are available for examination and subsampling. The data are stored as part of the National Geoscience Data Centre (NGDC) and the Marine Environmental Data and Information Network (MEDIN) Data Archive Centre (DAC) for Geology and Geophysics. Data are delivered via the BGS Offshore GeoIndex http://www.bgs.ac.uk/GeoIndex/offshore.htm. The activity and scan layers contains location information, metadata and links to scanned borehole logs, and the geological data layers contain observations and/or measurements as digital values. The data are applicable to a wide range of uses including environmental, geotechnical and geological studies. Reference: Fannin, NGT.

This dataset is the complete collection of the British Geological Survey (BGS) held Marine Survey data. The data held includes digital data and analogue records, plus associated physical sample material. Data are stored within the National Geosciences Data Centre (NGDC) and the Marine Environmental Data and Information Network (MEDIN) Data Archive Centre (DAC) for Geology and Geophysics. BGS have collected Marine Survey data since 1966 and have also been provided with a range of third-party data. The data includes geophysical data (seismic reflection, side-scan sonar, multibeam echosounder bathymetry and backscatter, gravity and magnetics) and sample data from boreholes, cores and seabed grabs (logs, geological descriptions, geochemical, particle size analysis and geotechnical data). The majority of surveys are within the United Kingdom Continental Shelf (UKCS) area. Individual survey data coverage varies, depending on survey type (sampling, geophysics, multibeam or multi-disciplinary) and objectives (regional or local, shallow or deep). These data are applicable to a wide range of uses including environmental, geotechnical, geophysical and geological studies. Data are delivered via the BGS Offshore GeoIndex www.bgs.ac.uk/GeoIndex/offshore.htm. Additional data are available on request enquiries@bgs.ac.uk.

This is the collection of cores and samples held by BGS for the sea areas around the UK. It includes material collected by BGS during its mapping projects and material donated to BGS by other organisations. The main core and sample types are grab samples (sea-bed), gravity cores, vibrocores and rock-drill cores (up to 6m in length), and borehole cores (up to 274m in length). The sea-bed grab samples are Holocene sediments present at the sea-bed and are stored in plastic jars. Where possible, sub-sample material has been retained after analysis. The bulk of the cores consist of Holocene and Pleistocene material. The rest are of bedrock ranging in age from Neogene to Pre-Cambrian. A lot of the core was collected in plastic liner tubing and the unlithified cores have been split vertically. The bulk of the material was collected in the late 1960s, 1970s and 1980s and early 1990's with ongoing additions of new sample and cores each year. The distribution is very variable, but, in general, there are grab samples and/or shallow cores spaced about every 5 - 10km across the entire UK Continental Shelf. In some localised areas the sampling density is much higher. The samples and cores are applicable to a wide range of uses including environmental, geotechnical and geological studies.

The British Geological Survey hold a collection of data recorded during marine geophysical surveys which includes digital data and analogue records. These data result from approximately 350,000 line kilometres of multi-instrument geophysical survey lines. The data include seismic, sonar, magnetic, gravity, echo sounder, multibeam bathymetry and navigation data. The seismic data are mainly for airgun, sparker, boomer and pinger. The data were primarily collected by BGS and the collection also includes additional third party data. The data are primarily from the UKCS (United Kingdom Continental Shelf). The data are stored within the National Geoscience Data Centre (NGDC) and the Marine Environmental Data and Information Network (MEDIN) Data Archive Centre (DAC) for Geology and Geophysics. The majority of legacy geophysical paper records are available as scanned images viewable via the BGS Offshore GeoIndex www.bgs.ac.uk/GeoIndex/offshore.htm. Other records can be scanned on request. Older records are of variable quality. Data not yet available online including segy are available on request enquiries@bgs.ac.uk. The data are applicable to a wide range of uses including environmental, geotechnical, geophysical and geological studies. Reference: Fannin, NGT. (1989) Offshore Investigations 1966-87.

The British Geological Survey (BGS) holds an archive of multibeam backscatter data from BGS, Maritime & Coastguard Agency (MCA) and other organisations. The data are stored within the National Geoscience Data Centre (NGDC) and the Marine Environmental Data and Information Network (MEDIN) Data Archive Centre (DAC) for Geology and Geophysics. BGS works with the partner DAC for bathymetry at the United Kingdom Hydrographic Office (UKHO) to archive backscatter data. The majority of the data were collected and processed for the Maritime and Coastguard Agency (MCA) under the Civil Hydrography Programme (CHP). Backscatter data is useful for seabed characterisation for geological and habitat mapping. View the backscatter image layer and download backscatter data (geotiff) via the BGS Offshore GeoIndex www.bgs.ac.uk/GeoIndex/offshore.htm. The data underlying the images are available on request enquiries@bgs.ac.uk. If further backscatter processing is required, BGS can provide a quote. View and download the related bathymetry data via the UKHO INSPIRE 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.

This data set contains the following original data for the deep seismic reflection surveys conducted by the BGS in various parts of the UK. The data consists of observers' logs, surveyors' reports, location data tapes, field data recording tapes and processed data tapes. The processed tapes are at various stages of processing from demultiplexed field data to migrated stack (not all available for all profiles) These data are kept as archive copies. They are generally available for academic and commercial use, subject to payment of fees (and, in a few cases, the agreement of co-owners of the data rights). There are Approximately 20 files of written records and 200 tapes.

The Marine Aggregate Levy Sustainability Fund (MALSF) commissioned a series of Regional Environmental Characterisation (REC) surveys via the Marine Environment Protection Fund (MEPF) to develop understanding of submerged habitats and heritage in Britain. The aim was to acquire high quality data to enable broad scale characterisation of the seabed habitats, their biological communities and potential historic environment assets. The surveys were conducted in the following areas - Outer Bristol Chanel (2003 – 2005), Eastern English Channel (2005 – 2006), South Coast (2007 - 2010), Outer Thames (2007), East Coast (2008 - 2009), Humber (2008 - 2009). 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 includes bathymetry, sidescan sonar, sub-bottom profiler, magnetometer, seabed video and photographs, Particle Size Analysis (PSA) data, vibrocore (logs and images). Data are delivered via the BGS Offshore GeoIndex www.bgs.ac.uk/GeoIndex/offshore.htm. Additional data are available on request enquiries@bgs.ac.uk. Other data types have been archived with the other MEDIN DACs as appropriate (UKHO DAC for bathymetry data and DASSH DAC for biological data). The MALSF ceased operation at the end of March 2011 (http://www.marinealsf.org.uk/).

MONA LISA (Marine and Onshore North Sea Acquisition for Lithospheric Seismic Analysis) seismic data was acquired by BIRPS (the British Institutions Reflection Profiling Syndicate) across the Ringkobing-Fyn High of the central North Sea were designed to study the crust near a hypothesized Caledonian age triple junction associated with the colliding continental crust of Laurentia, Avalonia (Gondwanaland) and Baltica. The specific target was the eastward continuation of the Caledonian Front (Iapetus Suture), as previously recognised on NEC (North East Coast line), MOBIL (Measurements over Basins to Image Lithosphere), NSDP (North Sea Deep Profile) and BABEL (Baltic and Bothnian Echoes from the Lithosphere) profiles, in northern Europe. 1112 km of data were acquired, recorded to 26 s two-way time.

The British Institutions Reflection Profiling Syndicate (BIRPS) shot approximately 12,000 km of deep, multi-channel seismic reflection data around the British Isles from 1981 to 1991 during 14 surveys. Recording depths vary depending on the purpose of the survey but range from 15 s to 40 s two-way time. Raw and processed digital data are archived by BGS who make the data available subject to the cost of reproduction and handling. Seismic sections and other analogue ancillary data are available for some surveys. Gravity and magnetic data may also be available.
