The database contains satellite images of the UK purchased by the BGS or on its behalf by NERC. It includes data from the Lansdat, SPOT, Radarsat and ERS satellites. The images are stored in proprietary format on various types of magnetic media. The data are currently stored by path-row scene numbers and as mosaics on tapes, CDs and drives. Entire UK is covered by the dataset, however, there are gaps in coverage from individual sensors. Coverage exists for countries (or parts of countries) where work has been carried out.
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from which data is obtained, Engineering Geology Laboratory Reports - (100s), Literature which may be published or unpublished - (100s).
Rocks, thin sections and paper registers: samples from past BGS surveys and projects overseas. Though neglected for several years, the collection has been re-opened for addition of new material from overseas projects and donations. Paper registers are arranged by accession order on a country by country basis. The records have not been placed in electronic format and are not currently machine readable.
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.
Stored in Murchison House, this dataset (FAUNGRAPHLOG_ED) is the BGS UK (North) collection of paper graphic logs from boreholes and measured natural sections, particularly in the Carboniferous of Scotland and northern England. Some 18000 of these records include hand written macrofossil occurrences and assemblages from certain (often subsequently interpreted) stratigraphical levels in the borehole or section. There is at present no separate index (either analogue or digital) to FAUNGRAPHLOG_ED but a pathway to it is FOSSLOC, the index to the Survey Collection of fossils from UK (North).
GIS Data Layer and Database including maps and detailed Indexes. Paper records and photographs, descriptive register is paper version from which the digital version was created. Data mainly captured in 1989, infrequent additions (approximately 1 entry per year) since then. Includes all man-made caves known to BGS in Nottingham, but there are many more to be located in the future.
The Borehole Geology database holds downhole lithological / lithostratigraphical data (with unit-bound lithological properties where appropriate) for boreholes identified within the Single Onshore Borehole Index (SOBI), which covers onshore and nearshore Great Britain. The database can store multiple interpretations for each borehole and properties assigned to each coded lithological unit. Available borehole geology properties include porosity, Munsell colour, grainsize, water struck, etc, and other valid property-types can be included when/if required.
A significant part of this data collection is geophysical survey data in digital form being derived data created during the subsequent processing and interpretation of the field data described in 'Nirex Magnetic Tape Archives - Raw Data'. These data were originally stored on a variety of media. With the overall aim of delivering an efficient and effective archive service, the data have been consolidated onto DLT cartridges. Some related data, which were either analogue, on obscure media or in unknown formats have been retained in their original form. British Geological Survey maintains a full catalogue of the data, as an Access database. The data sets that comprise the magnetic archive are the following: Seismic surveys: demultiplexed and processed data; Geophysical wireline logging of boreholes: wireline derived data including synthetic seismograms; cross-hole tomography. The ownership of NIREX (Nuclear Industry Radioactive Waste Executive) 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.
The BGS Rock Classification Scheme (RCS) is a comprehensive classification scheme for all types of rocks and unconsolidated sediments worldwide. It is intended to be used for classification of single rock samples and can be used without any knowledge of field relationships. It has been designed for use by people with a wide range of geological knowledge; from experienced professional geologists to technicians and drillers. It also allows names to be assigned according to the level of information about the sample. The system if hierarchical, ranging from very simple names such as igneous rock to highly detailed names such as mugearite, that can only be applied after chemical analysis. Rock names can consist of a root name e.g. granite and several qualifiers that impart more information e.g. grey-biotite-bearing granite. The classification scheme has been implemented as a hierarchical dictionary of codes for all rock types. The classification scheme is described in BGS Research Reports 99-02, 99-03, 99-06. The BGS Rock Classification Scheme was devised between 1993 and 1996 in response to a need from the Digital Map Production System project.
This is the core collection of photographs in BGS it represents photographs taken by professional photographers and selected by subject and quality for public reference in the BGS libraries. The collection dates from c 1890 to c.1995 and is organized in a series of sub-collections depending on which office the photographers were based. The collection covers photography taken in the field during the geological mapping programme. Series A, the main Land Survey collection for England and Wales, are all taken by professional photographers and are of high quality. Dates from c.1890 to the start of the current "P" system, the first 7500 are glass plates. Series B, Edinburgh, part of the main Land Survey collection for Scotland, full plate size and all glass plates. Series C, Edinburgh, part of the main Land Survey collection for Scotland, half plate size. Series D, Edinburgh, part of the main Land Survey collection for Scotland consists of large format negative size with additional 35mm transparencies, earlier parts of the collection are black and white, later, colour. Series L, Keyworth, the main Land Survey collection for Northern England and Wales emanating from the Leeds Office, all are taken by professional photographers and include large format black and white, colour originals and colour 35 mm transparencies. Access constraints are only physical constraints relating to handling negatives and glass plates. scans are available in the Geoscience Imagebase. Photographs are either: Out of copyright; Crown or NERC.
