Physical measurements of soil moisture, river stage, and groundwater levels from Ghana and Burkina Faso 2016-2019 (NERC Grant NE/M008827/1, NE/M008983/1)

The datasets consist of soil moisture (hourly-weekly), river stage (1 min), and groundwater level (hourly) collected as part of the BRAVE project (NE/M008827/1 and NE/M008983/1) to understand the resilience of boreholes in low-yielding aquifers in the River Volta Basin to climate. The data were collected from physical observatories in Sanon (Burkina Faso) and Aniabisi (Ghana). Soil moisture data were logged hourly beneath contrasting land uses and roaming soil moisture surveys were also undertaken across a wider access tube array. River stage was monitored at the catchment outlet in Sanon and groundwater levels were measured in both catchments.

Historic reconstructions of daily groundwater levels for eight boreholes in Burkina Faso (NERC Grant NE/M008827/1)

This dataset consists of reconstructions of daily groundwater levels for eight boreholes in Burkina Faso. Data for each borehole is provided in an individual csv file, with reconstructed groundwater level time series reported in metres above sea level (GWL, mASL). The groundwater level reconstructions were derived in 2019 as a part of the BRAVE project (NE/M008827/1 and NE/M008983/1) to develop an improved understanding of temporal variability in groundwater levels in sub-Saharan Africa. The reconstructions were derived using the lumped conceptual groundwater model AquiMod. Observed groundwater level time series for the eight boreholes were modelled using AquiMod, and the calibrated models were used with historic precipitation and potential evapotranspiration data to derive the reconstructions. The length of the time series of reconstructed groundwater levels varies between the boreholes due to differences in the length of the precipitation time series used to derive the reconstructions. Full details of this dataset are reported by Ascott et al. (2020).

Apatite fission track data from UKGEOS Glasgow borehole GGC01

Apatite Fission Track (AFT) single grain count and horizontal confined track length data acquired from 6 sandstones samples from UKGEOS Glasgow borehole GGC01 drilled in the Dalmarnock area of Glasgow. The sandstones were retrieved from depths of 65, 98, 135, 150, 168 and 198 metres and were Westphalian in age coming from the Middle and Lower Scottish coal measures. Each sample has its BGS Subsample SSK number and an ascribed name in reference to its depth of collection with the added initials of the researcher i.e., 65 AH. The data is presented in 2 files one containing the AFT count data and the other containing the AFT length measurements. The AFT count data of each sample is found in excel file containing the spontaneous and induced track counts of a grain and accessory data of that grain e.g., the calculated age (calculated using the program Isoplotr) and calculated uranium concentration. The AFT length data of each sample comes in a separate excel file with the measured lengths and c-axis corrected lengths of HCTs of a sample, all Dpar measurements are also listed here. Samples and data are derived from the UK Geoenergy Observatories Programme funded by the UKRI Natural Environment Research Council and delivered by the British Geological Survey.

WITHDRAWN: BGS-HPA (Health Protection Agency) UK OneGeology Radon Potential Dataset

OneGeology is an international collaborative project in the field of geology supported by 113 countries, UNESCO and major global geoscience bodies. It aims to enable online access to dynamic digital geological map of the world for everyone. An EU Joint Research Centre project is using OneGeology geological data as a framework for the production of a Geogenic Radon Map of Europe. The BGS-HPA UK Onegeology Radon Potential dataset provides, within a 1:625,000 scale geological framework, a general indication of how the estimated arithmetic mean ground-floor radon concentration varies within the United Kingdom. The indoor radon data is used with the agreement of the Health Protection Agency (HPA). Mapping of radon-prone areas at the OneGeology 1:625 000 scale can be used to inform European policy makers, politicians and the general public about the general variation of radon potential within the United Kingdom at the European scale. The dataset should not be used at scales larger than 1:250,000 or for regulatory (i.e. Building Control or Radon Affected Area) purposes in the UK.

Geomechanical properties of the Carboniferous Middle Coal Measures (Boreholes GGC01 and GGA08)

A brief description of ten core plug samples collected from borehole GGC01 (Glasgow, United Kingdom) is provided, as well as for twelve 15-50 g cuttings samples from 1m intervals within borehole GGA08. Samples were also collected from borehole GGA02 but not used for further analyses. Data comprise results from geomechanical tests, permeability and porosity measurements, and X-Ray Diffraction analyses performed on drillcore samples of sandstones, siltstones, mudstones and coals from eleven depth intervals within the GGC01 borehole. Geomechanical data include triaxial compressional strength, tensile strength, and frictional strength. Frictional strength data was also collected for cuttings samples of sandstones, siltstones, mudstones and coals from the GGA08 borehole. 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. Samples and data are derived from the UK Geoenergy Observatories Programme funded by the UKRI Natural Environment Research Council and delivered by the British Geological Survey.

Dissolved rhenium and other dissolved ions in Alpine catchments of the Erlenbach and Vogelbach (Switzerland) and the East River (Colorado, USA) (NERC Grant NE/I001719/1)

The measurements and data contained here were obtained to study the chemical weathering of sedimentary rocks, and more specifically the oxidation of rock organic carbon and the associated release of CO2. The primary aim was to better understand the production and mobility of the trace element rhenium during weathering, because this element has been proposed as a proxy for rock organic carbon oxidation. The study focused on three Alpine catchments that drain sedimentary rocks, which all experience moderate to high erosion rates where oxidative weathering rates are thought to operate faster. Two catchments were located in Switzerland - the Erlenbach and Vogelbach, and one catchment in Colorado, USA - the East River. To study chemical weathering and the production and mobility of rhenium, a suite of samples were collected to capture the source and products of weathering reactions. These focused on stream and river water, river sediments and weathering profiles collected on sedimentary rocks. The Swiss catchments, water samples were collected from 2011 and 2012 to capture changes in river flow and seasonal changes in hydro-climate. Samples were collected from a gauging station operated by the Swiss Federal Institute for Forest, Snow and Landscape Research - WSL. In the East River, samples were collected from the gauging station operated by the Lawrence Berkeley National Laboratory Watershed Function Scientific Focus Area from 2015 and 2016. Additional samples included snow samples collected from the Erlenbach. All water samples were analysed for their major dissolved ion content by Ion Chromatography. Dissolved rhenium concentrations were determined by High Resolution and Quadrupole Inductively Coupled Plasma Mass Spectrometry. Solid samples were digested and analysed for Re content by ICP-MS. These geochemical measurements were paired with water discharge data to quantify the flux of dissolved elements, using rating curves and flux-weighted average methods, and interpret the hydrological context of ion production and mobility through the landscape. This new data acquisition was funded by a European Research Council Starting Grant to Robert Hilton (ROC-CO2 project, grant 678779) and a Natural Environment Research Council (NERC), UK, Standard Grant (NE/I001719/1). Further details of subsequent data analysis and interpretation can be found in Hilton, R.G., et al., 2021, Concentration-discharge relationships of dissolved rhenium in Alpine catchments reveal its use as a tracer of oxidative weathering, Water Resources Research
