  • This dataset presents the amount of different magnesium carbonates under different conditions. Here, using batch reactor experiments and mineralogical characterization, we explored magnesite precipitation kinetics in chemically complex fluids whereby the impact of fluid acidity and alkalinity, NaCl, and MgO nanoparticles was investigated. The dataset was created within SECURe project (Subsurface Evaluation of CCS and Unconventional Risks) - https://www.securegeoenergy.eu/. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 764531

  • The data represent ground motion results obtained from Interferometric Synthetic Aperture Radar (InSAR) for the UKGEOS – Glasgow site. The InSAR techniques used is called Interferometric Point Target Analysis (IPTA) and the BGS processing is based on Sentinel-1 radar satellite data for the period August 2015 - June 2017. The results include time series of displacement (in mm) during this interval and average velocity across the whole period (in mm/yr) along the satellite Line of Sight (Hanssen, 2001). InSAR has provided information on the baseline conditions of ground stability ahead of any underground activity planned in at the Glasgow Geothermal Energy Research Field Site (GGERFS) as described in Bateson and Novellino (2019).

  • Groundwater temperature data from a shallow urban aquifer in Cardiff, Wales, UK between 2014-2018. Monitoring was undertaken as part of the ‘Cardiff Urban Geo-Observatory’ project . Boreholes are located within the urban area of the City of Cardiff, Wales, UK. The majority of temperature sensors were installed within boreholes that monitor a shallow Quaternary aged sand and gravel aquifer, however the made ground and the Triassic Mercia Mudstone also represented. Temperature sensors installed in 53 boreholes, between depths of 1.5m and 12- m below ground, with measurements every 30 minutes. The dataset comprises of just over 3.5 million temperature measurements. Monitoring was undertaken by the British Geological Survey and was designed to address knowledge gaps of subsurface urban heat island and it use for heat recovery and storage.

  • This dataset comprises palynological counts on sediments from IODP Expedition 374 Site U1521 to the Ross Sea, collected on the RV JOIDES Resolution. Marine palynomorphs are counted in 23 samples, and 7 samples were counted for terrestrial palynomorphs (pollen and spores). Shipboard biostratigraphy and magnetostratigraphy suggests the samples are early Miocene in age (McKay et al., 2019, Proceedings of the International Ocean Discovery Program).

  • This dataset provides an overview of hydrothermal alteration samples from the island of Milos, Greece, that were analysed using a portable infrared mineral analyser (PIMA) or AgriSpec spectrometer. During data acquisition, spectrums were input into The Spectral Geologist (TSG) to provide an instant and estimated mineral identification using the shortwave infrared (SWIR) part of the electromagnetic spectrum. The samples were acquired during field visits between 2017 - 2019 by the British Geological Survey and the GW4+ Doctorial Training Partnership (NE/L002434/1). This data was primarily used to aid sample collection for further hydrothermal alteration analyses to improve our understanding of regional and local paleo-hydrothermal activity across the island. Identification by the TSG provides an estimation only, and the raw data files in .txt, .fos and .csv formats, are supplied for each analysis in the attached zipped file. This may be useful within the metallic and industrial mineral mining sector and associated researchers. The data includes grid references (± 5 m), TSG interpretations, and field/sample observations noted during data acquisition. GW4+ Doctoral Training Partnership (NE/L002434/1) is supported by grant award GA/09F/139 – RMS E3557, and the British Geological Survey’s University Funding Initiative (BUFI S345).
