    A list of the laboratory reports produced from testing in the engineering geology laboratory. It includes report number, title and author's name(s). The reports themselves contain data on a wide range of geotechnical and geophysical laboratory tests, from standard and index tests to complex research. Test materials are highly varied, soils and rock, from the UK or overseas.

    A collection of reference drawings relating to investigations carried out by Nirex, during the period from 1989 to 1997. The drawings summarise the status of the geological investigation at Sellafield and include borehole locations, geology (surface, structure, sections etc) and geophysics (seismic, airborne, etc). Sites near Sellafield, in Cumbria, and Dounreay, in Caithness. The Nirex (Nuclear Industry Radioactive Waste Executive) geological archive was transferred to the British Geological Survey during 2000/2001. The BGS has undertaken to retain the records for a minimum of 50 years as part of its national geological archive. The ownership of Nirex was transferred from the nuclear industry to the UK Government departments DEFRA and DTI in April 2005, and then to the UK's Nuclear Decommissioning Authority (NDA) in November 2006.

    This digital data set contains original files of seismic reflection survey sections. Most data are within the UK Onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea) and foreign data. Most data were acquired for commercial hydrocarbon exploration and subsequently provided to BGS for use on specific projects. Some data were acquired by BGS and other public-sector bodies, e.g. BIRPS (British Institutions Reflection Profiling Syndicate), for academic research. These data are used for workstation-based interpretation. Some are kept as archive copies. There are approximately 50 tapes and 15 Exabyte cartridges. The data are mostly concentrated in areas prospective for coal, oil and gas.

    The Geophysical Properties dataset consists of density, velocity, magnetic susceptibility and thermal conductivity values, with related source, location and geology data. The data have been collected on a project basis, therefore the quality and completeness of the database coding is variable. The data is currently from the UK and Ireland although this may be extended. The data consists of samples with related data values - (1,000s), Density Values - Laboratory Measurements - (1,000s); Velocity Values - Laboratory Measurements - (1,000's), Magnetic Susceptibility Values - Laboratory Measurements - (1,000s); Magnetic Susceptibility Values - Field Measurements - (10,000s measurements on 1,000s samples). Borehole information for data obtained as Downhole profiles with related data values; British Rock Densities Project - Insitu density values obtained from the analysis of formation density logs - (10s boreholes with 100s values). Downhole Magnetic Susceptibility - Obtained for a confidential project with some offshore - (10s boreholes with 10,000s samples) . Thermal Conductivity - (100s boreholes with 1,000s samples), Mean Data Values derived from a data source such as published literature for a site or rock formation; Density - (100s), Magnetic Susceptibility - (100s). Information about the source from which data is obtained, Engineering Geology Laboratory Reports - (100s), Literature which may be published or unpublished - (100s). The database is not maintained and no new data has been added since 2004.

    The UK Onshore Geophysical Library was established in 1994 in conjunction with the Department of Trade and Industry (DTI) and the UK Onshore Operators Group (UKOOG). The Library manages the archive and official release of seismic data recorded over landward areas of the UK. By agreement with the DTI and HMSO, the Library operates as a registered charity, funded by revenues raised from data sales and donations, with the long term objective of bringing all available UK onshore digital seismic data into secure archival storage, whilst providing efficient access to all interested parties. BGS has access to the data at cost of copying only for science budget work. Data index on the BGS Geoscience Data Index.

    Collection of annual publications from the global network of magnetic observatories. They typically contain tabulations of hourly, monthly and annual mean values of the geomagnetic elements. Contains all magnetic observatory year books held by the World Data Centre for Geomagnetism (Edinburgh).

    This digital data set contains original files of seismic reflection survey location (navigation) data and dates from the late 1970s. These provide location information for the Digital Seismic Sections data set (DIGSEISECS) and some of the printed seismic sections of the Original Seismic Sections dataset (ORIGSEISECS) and Copy Seismic Sections dataset (COPYSEISECS). Most data are within the UK Onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea) and foreign data. Most data were acquired for commercial hydrocarbon exploration and subsequently provided to BGS for use on specific projects. Some data were acquired by BGS (British Geological Survey) and other public-sector bodies, e.g. BIRPS (The British Institutions Reflection Profiling Syndicate), for academic research. The data are used with the Seismic Locations and Sections Database (LOCSEC) and for workstation-based interpretation. There are approximately 20 tapes and 15 Exabyte cartridges. The data are mostly concentrated in coal, oil and gas prospecting areas.

    This document data set contains original prints, on paper, sepia or film, of seismic reflection survey location (navigation) maps. These provide the location data for the seismic sections of the Original Seismic Sections (ORIGSEISECS) and Copy Seismic Sections (COPYSEISECS) datasets. Almost all data are within the UK onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea) and foreign data. Most data were acquired for commercial hydrocarbon exploration and subsequently provided to BGS for use on specific projects. Some data were acquired by BGS and other public-sector bodies, e.g. BIRPS, for academic research. All maps are digitised upon receipt (see LOCSEC database) and then archived in this data set. (Copies used to be used for interpretation purposes but this is no longer the case.) Documents stored rolled in tubes. Approx 800 maps.

    This document dataset contains original prints, on paper, sepia or film, of seismic reflection survey sections, dating from the 1960s. Most data are within the UK onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea) and foreign data. Most data were acquired for commercial hydrocarbon exploration and subsequently provided to BGS for use on specific projects. Some data were acquired by BGS and other public-sector bodies, e.g. BIRPS (British Institutions Reflection Profiling Syndicate), for academic research. This data set is a master set; copies must be used for interpretation purposes. Documents stored rolled in tubes, approximately 10 sections per tube, approx 850 tubes. The data are mostly concentrated in areas prospective for coal, oil and gas.

    This dataset is an archive of original data for the geophysical logging of boreholes drilled by the National Coal Board (NCB) and its successor, British Coal Corporation (BCC). Data coverage is UK wide and dates from the 1970's to the privatisation of the coal mining industry, in 1994. The dataset includes approximately 2000 field data recording tapes and processed data tapes. The processed data tapes are at various stages of processing and consist of edited data and computed (CSU) data (not available for all boreholes). The data are kept as archive copies. The data are owned by the Coal Authority (CA), as successor to the NCB and BCC, BGS being the custodian under an agreement with the Coal Authority. No full catalogue or index available yet.
