Thicknesses of aquifer units in the subsurface of the Indo-Gangetic foreland basin, northwestern India. Data are organised by borehole and indicate the thickness of aquifer units, separated by non-aquifer material.

Joint BGS/Environment Agency dataset of aquifer designations for England and Wales at 1:50 000. The dataset identifies different types of aquifer - underground layers of water-bearing permeable rock or drift deposits from which groundwater can be extracted. These designations reflect the importance of aquifers in terms of groundwater as a resource (drinking water supply) but also their role in supporting surface water flows and wetland ecosystems. The maps are split into two different type of aquifer designation: superficial - permeable unconsolidated (loose) deposits (for example, sands and gravels), and bedrock - solid permeable formations e.g. sandstone, chalk and limestone.

Matlab m-file code to generate a probabilistic model of aquifer-body occurrence in the subsurface of the Indo-Gangetic foreland basin, northwestern India. The accompanying ArcGIS ASCII matrix files give aquifer-body percentages in successive 10 m depth slices for use within the model. File xxx_01.txt is for depths 0-10 m, file xxx_02.txt for depths 10-20 m, etc.

This vector dataset represents the vertical and non-vertical faults for the Fell Sandstone Formation (base Middle Border Group) in the Northumberland-Solway Basin (Carboniferous hot sedimentary aquifer resources).

These files include hydrochemical data and groundwater level time series for a number of boreholes and wells within the basement aquifers of the Romwe catchment. For each borehole/well there are associated depth, geology and use data. A time series study of abstraction was also carried out for a subset of wells. Time series rainfall data for a rain gauge in the catchment is also included. These data were collected through a series of projects: Small scale irrigation using collector wells: pilot project (CEH/BGS/Zimbabwe Ministry of Lands, Agriculture and Water Development; DfID funded) Sustainability of yield from wells and boreholes in hard rock aquifers (BGS; DfID funded) Regional groundwater recharge assessment in semi-arid areas (CEH/BGS; DfID-funded) The Hydrology of a dry land catchment in southern Zimbabwe, and the effects of climatic and land use change on shallow groundwater resources (PhD project, Uni. Reading/CEH) Integrated Catchment Management and Sustainable Water Resource Development in Semi-arid Zimbabwe (PhD project, Uni. Reading/CEH) Note: CEH (Center of Ecology and Hydrology) was known as ‘IH’ during the period of the study

This vector contour dataset represents the distribution of the estimated, theoretical potential 'geothermal resources' (in GJ/m2 or PJ/km2) for the Carboniferous Fell Sandstone Formation (Mid Border Group) in the Northumberland-Solway Basin. This grid is the heat-in-place, and represents the amount of heat contained in the productive parts of the identified aquifers (i.e. those with sufficient porosity and permeability to be considered hot sedimentary aquifer resources).

This raster dataset represents the depth in metres to the top of the Upper Devonian in the Midland Valley of Scotland (top Kinnesswood Formation) over the extent of the model developed by Kearsey, T.I., Receveur, M. and Monaghan, A.A., 2024. Modelled hot sedimentary aquifer geothermal potential of Upper Devonian strata in the Midland Valley of Scotland. Uncertainties in the model are linked to the absence of boreholes penetrating both the top and the base of the Upper Devonian (except the Inch of Ferryton well) and poor seismic reflection data in the centre of the basin where it is thickest and deepest. The extent of the geological units is as shown on the published BGS geology maps, considering the re-interpretation of the Kinnesswood Formation as Devonian in age. The model is presented with high uncertainty.

This raster dataset provides the maximum temperature in the Upper Devonian formations in the Midland Valley of Scotland. The reservoir temperature is modelled over the extent of the base of the Kinneswood Formation and Stratheden Group, based on an updated geological model created by Kearsey, T.I., Receveur, M. and Monaghan, A.A., 2024. Modelled hot sedimentary aquifer geothermal potential of Upper Devonian strata in the Midland Valley of Scotland. The model is presented with high uncertainty.

This raster dataset shows the modelled P50 distribution of the theoretical potential 'heat-in-place' (HIP) across the northern and southern early Carboniferous limestone in Great Britain (PJ / km2), at a resolution of 2500 m x 2500 m. The HIP is calculated for resource temperatures greater than 50 degrees Celsius, which represents the minimum temperature required for direct use of heat from hot sedimentary aquifer resources. The HIP characterises the heat resource available in an aquifer according to the USGS definition described in e.g. Muffler and Cataldi (1978). Its calculation is part of the research published by D J.R. Jones, T. Randles, T. Kearsey, T.C. Pharaoh, A. Newell (2023). https://doi.org/10.1016/j.geothermics.2023.102649. Areas of high uncertainty are delineated in the published paper.

This vector contour dataset represents the distribution of the estimated, theoretical potential 'geothermal resources' (in GJ/m2 or PJ/km2) for the Triassic sedimentary aquifers of the Sherwood Sandstone Group (SSG) in the East Yorkshire-Lincolnshire, Cheshire, Wessex and Worcester basins, for resource temperatures greater than 40 °C. This dataset is the heat-in-place, and represents the amount of heat contained in the productive parts of the identified aquifers (i.e. with sufficient porosity and permeability to be considered as a hot sedimentary aquifer resource). This dataset is derived from Rollin, K. E., G. A. Kirby, and W. J. Rowley. Atlas of geothermal resources in Europe: UK revision. British Geological Survey technical report WK/95/7, Regional Geophysics Group, 1995: https://webapps.bgs.ac.uk/data/publications/publication.html?id=21735106 and the European Geothermal Atlas (https://op.europa.eu/publication-detail/-/publication/9003d463-03ed-4b0e-87e8-61325a2d4456).
