The collection consists of borehole drill logs, site plans, borehole location plans, geological plans and completion plans for opencast coal sites in Scotland and Northern England. It includes records deposited by the Directorate of Opencast Coal Production (DOCP) and its successors, National Coal Board (NCB), British Coal and numerous private and licensed opencast mine. The NCB Scottish Area records are arranged by the NCB opencast site number. Many records of cored 'diamond' boreholes are held in the BGS Scottish Borehole Journal records. Northern England opencast records are mainly held with the ex-Newcastle Borehole Records. Copies of completion plans for Scotland are also held in the Coal Mine Abandonment Plan collection available on microfilm aperture cards. Opencast sites are indexed in the Land Survey Record Index (LSRI) database. The cored 'diamond' boreholes are indexed on Single Onshore Borehole Index (SOBI).

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 collection, amounting to c.6,000 records, consists of reports and data relating to geochemical sampling, geophysics, drilling and field mapping deposited by mineral exploration companies dating from c.1960 onwards. Major accessions include records of Mineral Exploration Incentive Grant Act (MEIGA) and reports and plans of Exploration Ventures Ltd (EVL) relating to NE Scotland. Indexed in Land Survey Record Index Database (LSRI).

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.

The map shows the location and line-identifiers of reflection seismic profiles acquired by the former National Coal Board and British Coal during their exploration for coal in the UK. Ownership of UK coal exploration data was transferred to the Coal Authority following privatisation of the UK coal industry. The Coal Authority have appointed the British Geological Survey as custodian of this important national geological data archive. These data are, in general, publicly available; however, access to data within active mining licences is restricted in that it requires the consent of the mining licensee. The Coal Authority data archive includes hardcopy and digital data for the reflection seismic profiles, such as film and paper prints, original field tapes, demultiplexed data, processed stacked data, navigation (location) data and observers' and surveyors' acquisition reports. But please note that not all data types are available for all profiles. The BGS will be pleased to provide information on data availability for named profiles or within specified geographic areas, together with cost estimates and options for supplying copies.

This dataset contains parametric data (epicentre, magnitude, depth, etc) for over one million earthquakes worldwide. The dataset has been compiled gradually over a period of thirty years from original third-party catalogues, and parameters have not been revised by BGS, although erroneous entries have been flagged where found. The dataset is kept in two versions: the complete "master" version, in which all entries for any single earthquake from contributing catalogue are preserved, and the "pruned" version, in which each earthquake is represented by a single entry, selected from the contributing sources according to a hierarchy of preferences. The pruned version, which is intended to be free from duplicate entries for the same event, provides a starting point for studies of seismicity and seismic hazard anywhere in the world.

Database of hydrogeological properties measured on core samples. Contains most determinations generated by BGS Wallingford Physical Properties Lab but some data is only available on paper. High quality data produced to strict laboratory quality standards.

This dataset represents a project-based collection of seismic interpretations of 2D and 3D commercial seismic reflection data. These data are integrated in a relational database in ORACLE in a data model called OpenWorks. Well log data, stratigraphic, velocity and well and seismic location data are also held in the database. Data interpretations are held within project indices by interpreter. Interpretations include faults and lithostratigraphic horizons. All data are commercial-in-confidence and cannot be supplied to any third party without the explicit permission of the customer or supplier.

Database of water levels in selected observation boreholes: daily, weekly or monthly measurements. Consistent set of boreholes in catchments relatively undisturbed by pumping distributed across most significant aquifer units in the UK. Most sites have more than 30 years of data, and some sites have considerably longer time series. The dataset represents only 5% of active groundwater monitoring networks run by UK measuring agencies. BGS holds other, historical, groundwater level data, including one off measurements and time series.

This layer of the map based index (GeoIndex) shows the location of site reports covering a wide range of drilling and site investigation work. Some 2000 reports include the logs from over 10 000 boreholes in addition to those held in the borehole index. The rectangles shown are drawn using the SW and NE corners of the site maps.
