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from which data is obtained, Engineering Geology Laboratory Reports - (100s), Literature which may be published or unpublished - (100s).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.

An index to over 600 ground geophysical surveys carried out in the UK for a variety of projects. A large number of these surveys were done in conjunction with the DTI Mineral Reconnaissance Programme in the 1970's and 80's, and many others were carried out at the request of BGS field mapping groups. Information held describes the survey objective, location of measurements, geophysical methods and equipment used, reports and publications, storage locations of data and results (for analogue and digital data), dates and personnel. There are two datasets; one shows the outline of the survey areas, and the other shows the actual survey lines within each area.

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 layer of the map based index (GeoIndex) shows the path the survey ship took whilst undertaking the ship gravity, magnetic and bathymetry survey. This index is based on data from approximately 350,000 line kilometres of multi-instrument geophysical survey lines. The data itself includes seismic, sonar, magnetic, gravity, echo sounder, multibeam bathymetry and navigation data, both in digital and analogue format. The data were primarily collected by BGS and the collection also includes additional third party data.

The Seismic Line Index database stores summary administrative information about the collection of printed seismic sections, Original Seismic Sections dataset (ORIGSEISECS). This includes: details of data ownership or source, date of acquisition, purpose of survey, confidentiality, media, survey acquisition and processing parameters, and storage location in BGS. 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 (British Institutes Reflection Profiling Syndicate), for academic research. There is also scope to add relevant information about the data held in Copy Seismic Sections (COPYSEISECS) and Original Seismic Shotpoint Location Maps (ORIGSPMAPS) datasets.

Data from geophysical surveys in many African countries carried out by the British Geological Survey for different agencies. The surveys range from regional gravity and airborne magnetic mapping to targetted surveys for mineral and water. Individual surveys do not yet have metadata entries: this entry describes a notional database that represents all geophysical surveys carried out within the region.

Data from geophysical surveys carried out by the British Geological Survey in many countries in the Middle East, the Indian sub-continent and Indo-China for different agencies. The surveys range from regional gravity and airborne magnetic mapping to targetted surveys for mineral and water. Individual surveys do not yet have metadata entries: this entry describes a notional database that represents all geophysical surveys carried out within the region.

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 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.

This database stores down-hole stratigraphic data to complement the seismic surface picks stored in the Seismic Locations And Sections Database (LOCSEC). Because these surfaces are chosen for their visibility on seismic data, they may not be directly equivalent to established BGS lithostratigraphic and/or choronstratigraphic divisions. However, the local coding system is based on and can relate to the BGS stratigraphic LEXICON. Stratigraphic picks are stored in terms of depth and seismic one-way travel time. Local borehole summary information (location, elevation, etc.) is used because both onshore and offshore boreholes are stored in this database. These data can be related to the BGS onshore borehole database by borehole registration, and to the offshore well database by DTI well-id. Additional tables (under development) provide information on hydrocarbon tests and their results. Almost all data are within the UK Onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea).
