Values of the geomagnetic field vector components computed from measurements made on land, at sea and in the air since 1900 all round the world. Repeat station data (collected at one location over many years and reduced to a magnetically quiet level) are an important part of this dataset. These data are useful for charting the Earth's magnetic field on time scales of years to decades.

Annual means of the geomagnetic field vector components from observatories around the world, from 1840 to the present day. At present there are about 160 observatories. These data are useful for tracking changes in the magnetic field generated inside the Earth. Data are produced by a number of organisations around the world, including BGS. Data are available in plain text from www.geomag.bgs.ac.uk. This data is connected to other geomagnetic data sets, but can be used without reference to them.

This dataset shows the distribution of Middle Jurassic, Upper Jurassic and Lower Cretaceous lithostratigraphic (UK Offshore Operators Association - UKOOA) units within the UK North Sea graben. The data are based on a subset of released exploration and appraisal wells from within the UK North Sea graben areas. The well data are concentrated in the areas overlying the deep sedimentary basins of the Viking Graben, Central Graben and the Moray Firth Basin, with fewer wells over the adjacent platforms. The UKOOA lithostratigraphic classification has been applied consistently.

This layer displays the urban areas for which there is an "urban geochemical mapping" report. An integral part of the G-BASE (Geochemical Baseline Survey of the Environment) mapping programme is to map and establish the soil geochemical baselines of urban areas. These data provide unique soil chemical information for the urban environment and are used to; assess the condition of soils within populated areas, identify and quantify human impact on soils in urban areas through comparison with the rural, natural soil geochemical background and Indicate elevated concentrations of potential harmful elements. 27 urban areas which have been sampled by the project to date.These include Glasgow, Nottingham, Ipswich and Cardiff.

A collection of small-scale non-series maps which offer whole-country coverage of the United Kingdom 1856-2013. Included in the collection are geological, tectonic, structural, mineral resource and geophysical maps, together with a small number of historical facsimile maps. Key geological maps included in the collection which ran to many editions are Geology of the British Islands 1:584 000 and the Geological Map of Great Britain 1:625 000. These maps are hard-copy paper records stored in the National Geoscience Data Centre (NGDC) and are delivered as digital scans through the BGS website.

The BGS database of geological maps is an index into BGS holdings of modern and historical published geological maps, geological standards and field slips, and also contains a range of other map series, including geophysical maps, geochemical maps, hydrogeological maps, thematic maps and other small-scale miscellaneous non-series maps. Historical vertical and horizontal sections, as well as indices to colours, are also included. The database comprises map metadata, including the title, theme, survey and revision years, publication years, mapped geological theme, base material, map function, colouration, approval status and the spatial extent of each map sheet. An accompanying file store contains high-resolution JPEG2000 scans for delivery, as well as various digital master and delivery formats. For a small number of maps, no scan exists. In total, the database contains over 240,000 scans of over 130,000 maps and field slips. The majority of the maps in the database cover Great Britain, but other regions are also represented, including a historical series of 1-inch maps of Ireland, 6-inch maps of the Isle of Man, 1:25 000 scale maps of the Channel Islands, and various overseas maps. The database contains a record of all geological maps produced by the British Geological Survey and its predecessors since the commencement of systematic geological mapping in the 1830s. The BGS Maps Database is mostly an archive of previous BGS maps, and is not the same as the latest BGS digital mapping. The maps within the database may differ significantly from BGS digital vector mapping. Further information about BGS digital vector mapping is available on the BGS website, under 'BGS Datasets'. The database has evolved over time, originally being a series of discrete databases. These databases have now been aggregated into a single dataset. BGS published maps, as well as 1:10 560 and 1:10 000 large-scale geological maps of England and Wales, and Scotland, are available through the BGS Maps Portal. Field slips and some thematic maps are not included on the BGS Maps Portal. The information about a map is normally a transcription from the map itself. Sometimes key information such as the title may not be actually printed on the map. Where this is the case the information is supplied in square brackets, e.g. [Kirk Maiden]. Information in square brackets means the information is supplied by the cataloguer and is not transcribed from the item.

The datastore for the BGS digital field data capture system contains databases that have been collected by field geologists and geoscientists using the MIDAS Tablet PCs. The databases replicate (in simple terms) the information and field observations that used to be recorded on paper fieldslips, notebooks and cameras. Depending on what is being mapped, each database can hold data from a complete series of field seasons, and contains points, lines, polygons, map face notes, sketches, photographs, tagged text, and structured data such as measurements and descriptions constrained by dictionaries and standards. Every item collected in the field using this system is attributed with a Unique User ID (UUID) that is constructed using the geologists ID and the date and time (to the second), along with a grid reference aided by a built-in EGNOS (European Geostationary Navigation Overlay Service) -enabled GPS (Global Positioning System). The store contains data collected across the UK and overseas. The scale varies depending on the project. MIDAS was first used in 2006 and each year more field teams are using it to replace pencil and paper records. The data are verified in this fully-relational datastore and transferred from here into the appropriate corporate databases for further manipulation.

The Regional Geochemical Atlases are the principal hard copy product of the British Geological Survey G-BASE (Geochemical Baseline Survey of the Environment) project. The majority of atlases are for stream sediment, with data on stream water and soil included where available. Separate stream sediment, soil and stream water atlases have been published for Wales. This dataset relates to the hard-copy atlases, which are available for Shetland, Orkney, South Orkney and Caithness, Sutherland, Hebrides, Great Glen, East Grampians, Argyll, Southern Scotland, Lake District, NE England, NW England and N Wales and Wales. The atlases were issued between 1978 and 2000. Each atlas comprises a set of separate interpolated heat-maps for each analyte, as well as descriptive and interperative information. The atlases provide an invaluable, systematic baseline of geochemical information for Great Britain, serving as a marker of the state of the environment against which to measure future change. Digital atlases and map products are also available for the Clyde Basin, central England, the London region and south-west England. National-scale digital atlas products are also available.

UK continental shelf seabed sediment data at 1:1 million scale. This data layer is the BGS contribution to the OneGeology project, providing UK onshore geological data at 1:625 000 scale and UK continental shelf seabed sediment data at 1:1 million scale.

The UK Compiled Topsoil Dataset (UKTS) is the most extensive topsoil geochemistry dataset for the UK available at the time of release (August 2024). The dataset consists of 82 georeferenced TIFF raster images (GeoTIFF format) with a cell size of 500 x 500 m, displaying the predicted concentrations for 41 chemical elements in UK topsoil and their respective standard error. The dataset is based on the geochemical analyses of 57,966 topsoil samples collected between 1978 and 2014 and analysed by X-Ray Fluorescence spectrometry (XRF). The UKTS was brought together by combining data from the following sources: i. the British Geological Survey’s (BGS) Geochemical Baseline Survey of the Environment (G-BASE) rural and urban topsoil dataset (which accounts for 76.4% of the topsoil samples included in the UKTS) ii. the Geological Survey of Northern Ireland (GSNI) TellusNI rural and urban topsoil geochemical survey dataset (13.8% of the UKTS samples) iii. the BGS-Rothamsted Research X-ray Fluorescence Spectrometry (XRF) rural soil dataset (RR-BGS XRF), based on sub-samples held at Rothamsted Research from the National Soil Inventory (NSI) of England and Wales sample archive, National Soil Resources Institute, Cranfield University (9.8% of the UKTS samples). An atlas of the compiled topsoil concentrations for the UK is available to download (https://nora.nerc.ac.uk/id/eprint/535963) and all maps are available to view within the UK Soil Observatory website (https://www.ukso.org). The dataset covers England, Wales and Northern Ireland, and the Clyde Basin in Scotland. The GeoTIFF raster image maps were produced from the interpolation by ordinary kriging of the concentration values in the source data points, using the geostatistical wizard in the geostatistical analyst toolbox of ESRI ArcGIS 10.8.
