    UKGEOS and Core Sample Analysis. Geomechanical testing was performed to determine triaxial compressional strength, tensile strength, frictional strength and permeability of sandstones, siltstones, mudstones and coals from eleven depth intervals within the GGC01 borehole, UK Geoenergy Observatories (UKGEOS), Glasgow, United Kingdom. Frictional strength tests were also performed on cuttings samples of sandstones, siltstones, mudstones and coals from the GGA08 borehole, Glasgow, United Kingdom. In total twenty-three tensile strength tests were performed on ten sampled intervals, and seven porosity measurements pre-and post-failure were taken. Nine triaxial compressive strength tests and twenty-one frictional strength tests were performed, with permeability measured both before and after failure or shear respectively. From compressive strength tests we also determined the Young’s modulus and Poisson’s ratio. Results of X-Ray Diffraction are also included in the dataset.

    The UK Geoenergy Observatories (UKGEOS) Glasgow 3D coal mine model outputs, created by the British Geological Survey, provide a semi-regional overview of the depth and extent of surveyed and probable coal mine workings, plus stone and coal roads surveyed within the mines. The model allows users to visualise the surveyed and probable coal mine workings to be found beneath this part of Glasgow, applicable at a scale of around 1: 25,000 to 1: 10,000. The data is supplied as grids, triangulated surfaces over a 5 by 4.15 km area, with the depth range to around 300 m below Ordnance Datum. The mine extents are ‘cut out’ of the UKGEOS Glasgow pre-drill bedrock model. This model describes both surveyed (recorded on mine abandonment plan) and probable coal mine workings before the UKGEOS Glasgow boreholes have been drilled, and was used to inform the expected sequence on drilling. Further details and model limitations can be found in the accompanying metadata report http://nora.nerc.ac.uk/id/eprint/522737

    The borehole information pack from borehole GGC01, site 10 of the UK Geoenergy Observatories (UKGEOS) Glasgow facility. This intermediate data release pack from BGS contains sedimentology, discontinuity and engineering logs, as well as the information contained within the initial release: composite and digital wireline logs; drillers summary logs and prognosis; sample recovery information spreadsheets; and daily driller's borehole records. The cored, seismic monitoring borehole was drilled between 19 November and 12 December 2018 to 199m producing a core of 102 mm diameter. The borehole was wireline logged in December 2018 and a string of 5 seismometers were installed in February 2019. A range of fluid, water and core samples were taken during the drilling process. The borehole information pack- intermediate release contains a range of logs on the core as well as images of that core, these data were acquired in the first half of 2019. More information is available in the accompanying metadata report http://nora.nerc.ac.uk/id/eprint/525009.

    The UK Geoenergy Observatories (UKGEOS) Glasgow superficial deposits GSI3D model outputs, created by the British Geological Survey, provide a semi-regional overview of the depth, thickness and extent of glacial and post-glacial lithostratigraphic units above rockhead. The model allows users to visualise the likely subsurface sequence to be found beneath this part of Glasgow, applicable at a scale of around 1: 25,000 to 1: 10,000. The data is supplied as grids and shapefiles over a 7 by 4.15 km area, with the depth range to around 40 m below Ordnance Datum. This model describes an interpretation of the shallow geology before the UKGEOS Glasgow boreholes have been drilled, and was used to inform the expected sequence on drilling.

    This summary borehole information release is for ‘as-built’ mine water and environmental baseline monitoring boreholes of the UK Geoenergy Observatories (UKGEOS) Glasgow facility at Cuningar Loop. The information pack from BGS contains a brief report with summary tables of locations, drilled depths, screened intervals and illustrative interpretations, and is accompanied with a spreadsheet and shapefile of the borehole locations and drilled depths. The purpose is to give potential users of the Glasgow Observatory an outline of the as-built infrastructure including condition of the target mine workings, as a summary of the more detailed information packs for each borehole. This dataset was updated in June 2020. Further details can be found in the accompanying report http://nora.nerc.ac.uk/id/eprint/526889

    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/.

    The borehole information pack from borehole GGA02, site 01 of the UK Geoenergy Observatories (UKGEOS) Glasgow facility. This release from the British Geological Survey (BGS) contains BGS and Drillers’ logs, cased hole wireline data, details on fibre-optic cable installation, a listing of archived rock chips and a descriptive report. The borehole was drilled between 17th June and 20th September 2019 (start of drilling to casing installation date) to 94.16 m drilled depth as a mine water characterisation and monitoring borehole. Unfortunately, during the final stages of construction grout entered inside the casing, the casing was damaged and the borehole is now available as a sensor testing borehole to 67.2 m. The cased borehole was wireline logged in January 2020. Rock chip samples were taken during the drilling process and have been archived at the National Geological Repository at BGS Keyworth. Further details can be found in the accompanying report http://nora.nerc.ac.uk/id/eprint/528076 DOI https://dx.doi.org/10.5285/189dac62-b720-4fde-8260-f129fb9b0233
