  • 1. Grids (in spreadsheet form) of interpreted parameters from the 3D time-lapse seismics (temporal and constructed depth thicknesses) at the Sleipner CO2 storage operation in the North Sea. 2. A synthetic seismic model of a CO2 wedge, to examine the relationship between wedge true thickness and temporal thicknesses. These datasets underpin following publications: Chadwick, R.A., Williams, G.A. & White, J.C. 2016. High resolution imaging and characterisation of a CO2 layer at the Sleipner CO2 Storage operation using time-lapse seismics. First Break, 34, 79-87. The source data comprise the Sleipner 3D time-lapse surveys which were acquired in 1994 (baseline), 1999, 2001, 2002, 2004, 2006, 2008 and 2010. The dataset used here for measuring temporal thicknesses is the 2010 high resolution dataset with constructed depth thicknesses from the 1994 baseline data. Grant number: EP/K035878/1.

  • Miscellaneous geological records for Scotland and Northern England of current or semi-current interest filed in order of accession. Some 65 accessions held which will be subject to review for permanent retention/destruction. Dataset created c.1970 and Indexed on Land Survey Record Index Database.

  • The Land Survey Archives consists of records of the Geological Survey in Scotland for permanent retention dating from 1860s onwards. The collection comprises geologists' field notebooks, miscellaneous field observations and reports, historical and biographical material, correspondence files, photographs, etc. Includes archival material deposited by outside individuals and organisations, eg. NCB (National Coal Board) Bore Book Collection. Survey archival material for Northern England will be incorporated. Some 380 accessions held amounting to over 7,000 items. Indexed at collection level in Land Survey Record Index (LSRI). Plans abstracted and held separately in Land Survey Plans Collection.

  • The UK Sand and Gravel Database was compiled during the production of the Industrial Mineral Assessment Reports. The Department of the Environment commissioned this Report series from the British Geological Survey. Data collection extended from the first IMAU report in 1969 to the last report in 1990. The dataset is complete and is derived from reports with some additional boreholes that were never published. Standard procedures were adopted for whole project. Each report studied the sand and gravel resources of an area of between one hundred and two hundred square kilometres. Specially commissioned boreholes on a one kilometre grid basis were used in conjunction with existing geological knowledge to make a resource level assessment of the volume and quality of sand and gravel resource available. A total of 12,563 boreholes were drilled, 53,721 Lithological units described and 54,128 samples collected and graded. This information is presented in the appendixes of the individual reports and as a single database. Data collection is complete. Only factual corrections to the data are occasionally made. The dataset includes the borehole location, total depth, unit thickness, unit lithologies, and grading information.

  • This dataset is an index of the Survey Collection of fossils for Scotland and Northern England. It is the digital equivalent of the analogue (card) index. The latter contains some 31k records, c.70% of which has been transcribed. The continually growing Survey Collection comprises about 450k samples (including nearly 30k specimens from the John Smith Collection) which are individually registered in c.150 leather bound volumes. The Oracle relational database BGS_FOSSLOC is a first step in ascertaining what registered fossil materials exist for certain areas, who collected them and when, their geographical and stratigraphical details, the type of collection (whether from boreholes or exposures), and any covering technical reports. It is also a pathway to an extensive and unique collection of paper graphic logs, some 18k of which record annotated information on fossil occurrences and assemblages at certain stratigraphical levels (particularly in the Carboniferous) in Scotland and Northern England.

  • The database contains scanned photographs (at 1016dpi) of the UK and various locations around the world. Some are single band (black&white) others are 3 band colour. The images are stored in various formats on various types of magnetic media: .COT raw scans can only be used on the Intergraph ImageStation; .JPG (Intergraph format); .TIF. Processed scans may also be saved as stereomodels (with project data) and as orthophotographs. Mono coverage for most of the UK and we are constantly acquiring stereo data. Data is updated when unscanned areas are required by projects.

  • This document data set contains paper copies of many of the seismic reflection survey sections from the original seismic sections data set (ORIGSEISECS) . These have been made for interpretation. 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 Institutes Reflection Profiling Syndicate ), for academic research. The documents are dyeline prints or plain-paper photocopies. They are stored folded in boxes, approx 40 sections per box, approx 530 boxes. There are a lot of duplicates, there being an interpreted and uninterpreted copy of many profiles. Mostly concentrated in areas prospective for coal, oil and gas.

  • A collection of regional geochemical data, mainly from stream sediment surveys, gathered from many BGS overseas projects since 1960s. Some areas are well covered and well documented with data available digitally on CD-ROM. Projects from 1960s and 1970s generally have no digital data and information exists only in paper form.

  • 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.

The data are mostly concentrated in areas prospective for coal, oil and gas.
