The UKTSraster consists of 82 Georeferenced TIFF raster images (GeoTIFF format) with a cell size of 500x500 m, displaying the predicted concentrations for 41 chemical elements in UK topsoil and respective standard error. The UKTSraster 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 UKTSraster covers all of 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 ArcGIS 10.8 (ESRI®).

The UK Geoenergy Observatories (UKGEOS) Glasgow facility, baseline soil geochemistry dataset released from the BGS comprises an excel file with two spreadsheets. The first spreadsheet contains information on the chemical composition of 90 topsoil (0 - 20 cm) samples collected from seven initially proposed borehole sites for the UKGEOS Glasgow facility, and from two control sites, in February-March 2018 (03-18). Ten samples were collected from each site prior to installation of the UKGEOS Glasgow facility, and underwent laboratory analysis. Chemical data for pH and the total concentrations of 54 inorganic and 75 organic substances in the soil samples are presented. In addition, the dataset contains locational and descriptive information about the samples noted during sampling. The analyte name, element chemical symbols, analytical method, units of measurement and limits of quantification are recorded in header rows at the top of the spreadsheet. The dataset includes qualifiers, highlighting any quality control issues reported with the data. The data qualifiers are explained in the second spreadsheet released with the data. Further details about the dataset can be found in the accompanying report http://nora.nerc.ac.uk/id/eprint/527798/.
