  • IDA272269 Methane and CO2 gas concentrations and stable isotope analyses of cutting samples from GGA05 and GGA08 boreholes of the Glasgow UKGEOS facility. Cutting samples were collected approximately every 3m depth in gas tight isojars by the BGS. Geochemical gas analyses was carried out at the Scottish Universities Environmental Research Centre (SUERC) and consisted of bulk concentration analysis using gas chromatography; followed by δ13CCH4, δ13CCO2, and δD stable isotope analyses on a methane combustion line (full methods attached). This data was collected to investigate the variability of gas fingerprints with depth within the Glasgow coal mine workings, and unmined Carboniferous coal measures. 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.

  • The dataset worksheet contains a list of core samples taken during IODP Exp 350 and foraminifera-based data for selected samples. The work was started with the aim of reconstructing palaeoproductivity changes (namely surface-to-deep carbon isotope gradients and U/Ca measurements) over tephra layers in order to test the ‘ash fertilisation hypothesis’. However, the work has been temporarily halted given the on-board volcanologists ongoing concerns that the ash layers in the selected cores have been reworked and therefore are not primary. Because of the induration and silicification of the core samples at quite shallow depths in the core, the other aim of the project (to reconstruct palaeoceanographic changes from 16-0 Ma) was not possible. The spreadsheet contains a full list of samples and a list of samples that have been examined and analysed. The data worksheet contains the no. of Globigerinoides ruber (with weight), Oridorsalis umbonatus, Uvigerina spp. and Cibicidoides spp. specimens for specific samples. For selected samples, stable oxygen and carbon isotopes are given and a graph of the carbon isotopes vs depth in core is presented.

  • IDA267644 Methane and CO2 gas concentrations and stable isotope analyses of select core samples from GGC01 borehole of the Glasgow UKGEOS facility. Core samples were collected approximately every 10m depth in gas tight isojars by the BGS. Geochemical gas analyses was carried out at the Scottish Universities Environmental Research Centre (SUERC) and consisted of bulk concentration analysis using gas chromatography; followed by δ13CCH4, δ13CCO2, and δD stable isotope analyses on a methane combustion line (full methods attached). This data was collected to investigate the variability of gas fingerprints with depth within the Glasgow coal mine workings, and unmined Carboniferous coal measures.

  • The dataset includes oxygen and carbon stable isotopes measured on multispecies planktonic foraminifera from 15 million years ago to the present, as well as trace elements ratio and abundance counts. For the code availability and instructions to run the cGENIE version and experiments see Boscolo-Galazzo, Crichton et al. (2021).

  • This dataset contains the nitrogen, oxygen, and lithophile element geochemistry of whole rock, and distribution coefficients, and stable isotope fractionation factors for biotite, orthoclase, and plagioclase mineral separates from the Loch Doon Zoned Pluton, Scotland. The samples were collected from the northern limb of the Loch Doon pluton and are petrologically classified as are granodiorites and granites which show geochemical evidence for being a cogenetic zoned pluton. The data were collected over a time period of 2019-2022. These data were collected to investigate elemental partitioning and stable isotope fractionation of nitrogen between biotite, plagioclase, and orthoclase relative to each other and to the system (whole rock) during magmatic differentiation. This project was curiosity-driven science, and the anticipated interest groups are assumed to be the wider research community via scholarship and analytical protocols. These data were collected by an international team of scientists as part of Dr Toby Boocock’s PhD project.
