Borehole and transmissivity dataset, Uganda (NERC Grant NE/M008606/1) - superseded

Revised dataset available here http://data.bgs.ac.uk/id/dataHolding/13607942 .This dataset comprises 655 borehole records and previously unanalysed pumping tests from across Uganda that were compiled from historical borehole records held within 9 district water offices. The dataset is a compilation of historical borehole records held within nine district water offices across Uganda. These data originated from numerous drilling campaigns undertaken by private contractors in each district to site and construct hand-pump borehole community water supplies between 2000 to 2018. In total over 1000 paper borehole records were initially collated and reviewed. This work was carried out over several months visiting the district water offices. Following a quality assurance procedure 655 records were transcribed to create a digital dataset. Each borehole record in the dataset contains a series of metadata alongside the pumping test data (e.g. pump depth, static water level, pumping rate and duration) including locational information (e.g. coordinates, water strike, borehole depth, borehole lithologies). The dataset is delivered as a series georeferenced site information within an MS Excel spreadsheet file.

Dual stable isotope analysis of nitrogen and oxygen in nitrate in groundwater from Northern Province Chalk in Yorkshire, UK (NERC Grant NE/L002574/1)

Dual stable isotope analysis comprising nitrogen-15 and oxygen-18 ratios for groundwater samples collected every 2-3 months over one hydrogeological year from the East Riding of Yorkshire. Isotopic ratios for nitrogen-15, oxygen-18 are both presented as raw and processed to NAIR and VSMOW, respectively. The data are in the form of a Microsoft Excel workbook containing Isotope Ratio Mass Spectrometer runs. The data were collected to understand key sources of nitrate contamination in Chalk groundwater and the dominant processes they undergo, and the extent of any attenuation. The Chalk catchments and the River Terrace Gravel catchment were compared, allowing conclusions to be drawn on the role of nitrate transformation, and the dominant location of transformations, to increase understanding of nitrate dynamics in agricultural systems. Groundwater samples were collected by the University of Leeds, the Environment Agency, Yorkshire Water and South East Water. Nitrate isolation and data interpretation carried out by Josephine McSherry, supervised by L. Jared West and Simon Bottrell. Mass spectrometry was carried out by Rob Newton and Bob Jamieson at the University of Leeds. No isotopic data are absent from the dataset, however oxygen contamination (resulting from the isolation method and since resolved) severely affected run O34b-O. Hydrochemical data relevant to the groundwater samples are not included as they are the property of the Environment Agency, Yorkshire Water or South East Water.

A global Ediacaran-Cambrian Age Model of 130 geological successions, with radiometric ages (zircon U-Pb CA-ID-TIMS), carbon (δ13Ccarb) and strontium (87Sr/86Sr) isotope data (NERC Grant NE/T008458/1)

We present new age models for the Ediacaran-Cambrian which lacks a robust global temporal framework. This interval marks the radiation of animals, but there are major uncertainties in the evolutionary dynamics of this critical radiation and its relationship to changes in palaeoenvironmental changes. Here we present global data from 130 successions that enable us to create four new possible global age models (A to D) for the interval 551–517 million years ago (Ma). These models comprise composite carbonate carbon isotope (δ13Ccarb) curves, which are anchored to radiometric ages and consistent with strontium isotope chemostratigraphy, and are used to calibrate metazoan distribution in space and time. These models differ most prominently in the temporal position of the basal Cambrian negative δ13Ccarb excursion (BACE). Two age models (A and B) place the BACE within the Ediacaran, and yield an age of ~538.8 Ma for the Ediacaran-Cambrian boundary; however models C and D appear to be the most parsimonious and may support a recalibration of the boundary age by up to 3 Myr younger. All age models reveal a previously underappreciated degree of variability in the terminal Ediacaran, incorporating notable positive and negative excursions that precede the BACE. Nothwithstanding remaining uncertainties in chemostratigraphic correlation, all models support a pre-BACE first appearance of Cambrian-type shelly fossils in Siberia and possibly South China, and show that the Ediacaran-Cambrian transition was a protracted interval represented by a series of successive radiations. Data were compiled by Fred Bowyer, with support from Andrey Yu. Zhuravlev, Rachel Wood, Maoyan Zhu, Graham Shields, Ying Zhou, Chuang Yang, Simon Poulton, Dan Condon, Andrew Curtis.

Palaeointensity (PINT) database v8.0.0 (NERC Grants NE/P017266/1, NE/S008330/1, NE/P00170X/1)

The palaeointensity (PINT) database of estimates of absolute palaeomagnetic field strength throughout Earth history. The aim of the PINT database is to catalogue all absolute palaeointensity data with ages > 50 ka which have been published in the peer-reviewed literature. The data is provided at the cooling unit level or, in the case of large intrusions, at the sampling site level. In some cases, the data provided in the publication only allows averages of multiple cooling units to be given. In such cases, this should be a Field. The database was published in Bono et al. (2021, https://doi.org/10.1093/gji/ggab490) and an online version is available at http://pintdb.org/

X-ray CT scan of true triaxially deformed Darley Dale sandstone sample tts6 (NERC Grant NE/N003063/1)

X-ray CT scan dataset of Darley Dale sandstone sample tts6. This sample was deformed in a true triaxial apparatus, and is fully described in the PhD thesis of Stuart (1992, UCL). The sample is a cube, measuring approximately 50 mm on a side. The sample experienced two sets of true triaxial deformation (test DDSS0009 and DDSS0010), with different applied stresses in the 1, 2 and 3 directions. This deformation produced distinct families of brittle microcracks, which were detected using acoustic emissions and seismic velocity analysis. This X-ray CT scan dataset was collected in 2019 at the University of Aberdeen by Dr Stewart Chalmers and Dr Dave Healy.

Multiscale models for MCFC, Fischer-Tropsch synthesis and CO2 compression

A Multiphysics model for a molten carbonate fuel cell (MCFC) developed in COMSOL. This is a multiphysics model for a MCFC. It has been built using COMSOL Multiphysics®. It enables the user to investigate the composition of the fuel and flue gases as well as the design parameters (e.g. the thickness of the electrolyte) on the performance of the fuel cell and the efficiency of CO2 capture. For example, the impact of CO2 concentration in the flue gas on the fuel cell performance and the carbon capture factor (which is a measure on how much CO2 has been concentrated from the flue gas) could be evaluated. One of the key findings show that the fuel cell performance improves and the carbon capture factor decreases with increasing CO2 in the flue gas. A process model for liquid fuel production through reverse water gas shift (RWGS) and Fischer-Tropsch (FT) developed in Aspen Plus. The model enables the user to examine the production of liquid fuels through CO2 hydrogenation followed by FT synthesis. The user can test different conditions for the RWGS such as H2/CO2 ratio and temperature and investigate how these changes affect the CO2 conversion. The product distribution for the FT follows the Anderson–Schulz–Flory (ASF) distribution. The ASF model is applied in a FORTRAN calculator and assumes a chain growth probability factor (α) of 0.9; the user may change the value of α and investigate how this affects the product distribution. A CO2 compression model developed in Aspen Plus. The model liquefies the captured CO2 stream through multistage compression with intermediate cooling and water condensation/removal.

Ptychotomography of Bishop Tuff Zircons (NERC Grant NE/P002498/1)

Nanoscopic (50 < size < 150 nm) magnetic particles embedded within the unaltered interior of mineral crystals like zircons (ZrSiO 4 ) make ideal candidates to record the information about the earth's magnetic field (geodynamo). Information regarding the magnitude of the field can be obtained by measuring the natural remnant magnetization (NRM) of these carriers and further information on the approximate size range of the carriers can be obtained by carrying out thermal remnant magnetization measurements (TRM). However very little is known about the actual morphology and spatial distribution of these carriers in order to understand the fundamental parameters influencing paleomagnetic recording. We propose to image pristine zircons crystals with simple geological histories containing large remnant magnetization using ptychotomography in order to investigate the size, shape and spatial distribution of nano-paleomagnetic carriers. This would also give us an opportunity to fine tune the ptychotomographic setup at I13-coherence branch. This data package consists of 3D maps of Bishop Tuff Zircons, relatively young. The folders contain a stack of .tiff files which can be loaded into imagej, dragonfly, aviso for segmentation purposes.

Mass flow and tsunami modelling results for potential events in the Sciara del Fuoco of Stromboli (NERC NE/T009438/1)

Numerical models of mass flows and tsunamis that they generated with their entrance in the sea. The mass flows propagate in the Sciara del Fuoco of Stromboli. The mass flows are not real events, but are rather used as a sensitivity analysis to examine tsunamigenic potential of mass flows of landslides and pyroclastic flows of different durations, volumes and coherence. The data was generated with the two fluid version of the Volcflow model. The material includes tsunami height measurements (plotted as well as raw data) for each run recorded by virtual gauges located around the island (map of gauges included), maximum wave height data in the area around the island and at the shores, a video visualisation of the mass flows and resultant tsunami waves, and a figure of the final deposit from each modelled mass flow. The numerical model simulations were carried out by Symeon Makris. The Volcflow code is not included in the submitted material but it is open source and can be downloaded here: https://lmv.uca.fr/volcflow/

U-Pb isotopic data for Chelyabinsk meteorite phosphates (NERC Grant NE/L002507/1)

U-Pb isotope ratio data set for numerous phosphate (apatite) grains in two thin section samples of the LL5 S4-6 Chelyabinsk meteorite. One section is of the S4-6 light lithology, and another of the S5-6 dark lithology. Samples analysed were section ‘A' (light lithology) and section ‘B’ (dark lithology) of Chelyabinsk, both from the Open University School of Physical Sciences sample collection. The results demonstrate variability in degree of Pb-loss during collisional reheating from pristine versus damaged apatite crystal domains. These results are reported for a meteorite fall which originally happened near Chelyabinsk in Russia. The results otherwise have no geographic location, as this is a sample of an asteroid. All measurements were made in December 2020. These data were collected using Secondary Ionisation Mass Spectrometry (SIMS) with a CAMECA IMS 1280 at the Institute of Geology and Geophysics, Chinese Academy of Sciences (IGGCAS). The thin sections were polished with colloidal silica, cleaned, and coated with gold prior to analysis. Microtextural information was obtained prior to analysis using a combination of back-scatter-electron, cathodoluminescence, and electron-back-scatter-diffraction analysis. Data were obtained to test hypotheses relating to the competition between macro-to-meso-scale thermally-driven variation in Pb-loss rates versus microscale variation driven by grain-specific features, e.g., fracture networks. An article describing and discussing these results, including further methodological steps in their collection and processing, is due for publication. This information is currently available in preprint form on arXiv: https://arxiv.org/abs/2112.06038
