Site investigation and geotechnical data received by BGS from 3rd party organisations in AGS file format. When received by BGS the data is validated against predefined rules, processed and stored in the BGS AGS agnostic store. This data is delivered as received e.g. no interpretative values or observations are added to the data by the BGS. For more details about the Association of Geotechnical & Geoenvironmental Specialists (AGS) see: https://www.ags.org.uk For more details on depositing AGS data with BGS see: http://www.bgs.ac.uk/data/ags To access AGS data held by BGS: http://mapapps2.bgs.ac.uk/geoindex/home.html?layer=AGSBoreholes

The Geotechnical Database contains information about site investigation reports, boreholes and samples. It contains geotechnical measurements taken over borehole intervals and on samples. Some of the data is obtained digitally from AGS files (Association of Geotechnical and Geoenvironmental Specialists - File Transfer Format), some is obtained manually from Site Investigation Reports stored in the National Geoscience Data Centre. The database currently contains geotechnical data from over 450 000 laboratory test samples and core descriptions, borehole observations and in situ tests from over 96 000 boreholes extracted from over 4800 site investigation reports. The database underpins BGS Geo-engineering properties and processes research and is an important information resource for answering enquiries and providing for the data needs of external customers.

The Single Onshore Borehole Index (SOBI) is an index of over 1 million boreholes, shafts and wells and references collections of digital and analogue records from all forms of drilling and site investigation work held by the BGS. The index covers onshore and near shore boreholes from Great Britain dating back to at least 1790 and ranging from one to several thousand metres deep. Some 50,000 new boreholes are added each year. The majority of the records contain written descriptions of the ground encountered. The SOBI index database originated in 1988 from a number of existing tables and from data input from a variety of coding forms. Therefore not all fields in the database are populated and data that should be in some fields may currently form part of the entries in another. The index is available on the BGS website via the Geoindex

During the period from 1989 to 1997, Nirex undertook extensive geological investigations at sites near Sellafield, in Cumbria, and Dounreay, in Caithness, to examine whether or not they were suitable locations for a deep repository for radioactive waste. At Sellafield, thirty deep boreholes, and a further thirty-five shallow boreholes, were drilled. The majority of the deep boreholes were drilled to obtain continuous core and some 18.7km of rock core arose from the investigations. Two deep boreholes were drilled at Dounreay, totalling 2,286 metres of drilling. Again, much of the drilling was to obtain continuous core. In most of the boreholes a suite of data acquisition techniques were used, including: continuous coring, geophysical wireline logging, hydraulic testing, sampling and analysis of groundwaters. Mineralogical data were acquired by detailed core observation, petrographic analysis, fluid inclusion analysis and stable and radiogenic isotope studies. Testing on samples from the rock cores was undertaken to determine petrological, mineralogical, hydrogeological, geophysical and geotechnical parameters. 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 collection of downhole CCTV (Closed Circuit Television) recordings and backup tapes for worldwide SKYLAB satellite imagery. CCTV recordings carried out down boreholes, mainly drilled for water, were undertaken by BGS for specific commercial contracts in Great Britain, and may also have associated geophysical data. The collection started in 1997, and the present holdings are 138 videos, with infrequent additions. Video recordings on other topics may be added.

The dataset is a subset of the BGS borehole material database, created on August 1st 2015 covering only the Bowland-Hodder geological unit (as defined and mapped by Andrews et al., 2013). It shows all boreholes (name, location and registration details) for which BGS hold borehole material (drillcore, cuttings, samples and their depth ranges). This data will add value to existing NERC (Natural Environment Research Council) data by allowing a simple route for users to identify borehole material from the Bowland-Hodder interval.

Index to reports of site investigations produced by external organisations carried out for all forms of site investigation. The Oracle index was setup in 1988 and covers the whole of Great Britain, all site investigation reports are indexed but the level of detail in the index for each record may vary. The reports date back to the 1950's and may contain information on boreholes, trial pits, laboratory tests and chemical analyses etc.

Collection of individually registered specimens and cuttings from onshore boreholes drilled in England and Wales by BGS, commercial and public bodies since the establishment of BGS in 1835. The collection has been developed as part of the BGS responsibility to establish and maintain a National Borehole Collection. The collection is updated on a daily basis by the addition of new data and by the modification of existing data. The collection contains all registered borehole samples for England and Wales, Scottish borehole samples are excluded. Details of the collection are held on the 'Borehole Materials Database', and may be accessed over the internet from the BGS web site.

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).

New acquisitions of all forms of geological data received from external organisations are recorded in the accessions database and the digital or analogue data itself is then available to users. Data is in the form of reports, plans and digital information. This information comes from a wide variety of sources, including public bodies and agencies and commercial organisations. The data itself will be incorporated into existing corporate collections or may form a new collection in its own right. The rate of transfer will depend on priorities and requirements of both internal and external users. Data is continuously removed from the collection, all except recently received material will have been processed.
