  • Organic carbon and nitrogen and bulk nitrogen isotope data and metal abundance data for siltstones and shales of the Mesoproterozoic Diabaig Formation. For a detailed description and interpretation, see Stüeken, E.E. and Prave, A.R., 2022. Diagenetic nutrient supplies to the Proterozoic biosphere archived in divergent nitrogen isotopic ratios between kerogen and silicate minerals. Geobiology.

  • Porosity of core samples SSK111464 (sandstone) and SSK111465 (shale) calculated using backscatter electron SEM images of carbon coated thin sections processed in ImageJ Fiji software. 85 images of SSK111464 (sandstone) used and 74 images of SSK111465 (shale) at various magnifications. Core samples from UKGEOS Glasgow Observatory, borehole GGC01. 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.

  • Organic carbon, total nitrogen, total reduced sulfur and carbonate-associated sulfur isotopes measured on decarbonated stromatolite samples from the Paranoa Group (1.1 Ga).

  • The BGS Debris Flow Susceptibility Model for Great Britain v6.1 is a 1:50 000 scale raster dataset of Great Britain providing 50 m ground resolution information on the potential of the ground, at a given location, to form a debris flow. It is based on a combination of geological, hydrogeological and geomorphological data inputs and is primarily concerned with potential ground stability related to natural (rather than man-made) geological conditions and slopes. The dataset is designed for those interested specifically in debris flow susceptibility at a regional or national planning scale such as those involved in construction or maintenance of infrastructure networks (road or rail or utilities), or other asset managers such as for property (including developers and home owners), loss adjusters, surveyors or local government. The dataset builds on research BGS has conducted over the past 15 years investigating debris flows. The model was designed to identify potential source-areas for debris flows rather than locate where material may be deposited following a long-run-out failure i.e. the track and flow of debris. This work focuses on natural geological and geomorphological controls that are likely to influence the initiation of debris flows. It therefore, does not consider the influence of land use or land cover factors.

  • This data pack contains information from geotechnical and contaminated land investigations carried out at potential sites for the development of the UK Geoenergy Observatory in Cheshire. Following these investigations, a decision was made to move the proposed observatory to Thornton Science Park. None of the sites discussed in this data pack are in scope for development as part of the Cheshire Observatory. In total 16 holes were drilled using a variety of techniques. The only hole to be drilled using rotary coring was BHA-101. This borehole was cored extensively and logged with wireline geophysical tools. As such this is the main focus of the data pack. BHA-101 was drilled to TD of 121.2 m between 19-Nov-2020 and 09-Dec-2020. Drill core was collected from 51 m – 121 mm with 100 mm diameter. This initial data release pack from BGS contains composite and digital wireline logs alongside daily driller's borehole records.

  • MEDIN Data. Within the project (WFA-CPC EMFF Protecting Our Seas), benthic and geophysical surveys were undertaken in the Severn Esturary/Môr Hafren SAC to explore the location of Sabellaria alveolata reefs, and collected bathymetry, sidescan sonar, AGDS and acoustic imagery data (ARIS) to identify areas of variable ground or potential features. A ten-day survey was undertaken in July 2020 to collect broad-scale acoustic data using an interferometric swath bathymetric system (GeoSwath Plus) and Acoustic Ground Discrimination System (RoxAnn™ AGDS). Twelve secondary survey areas were selected to be investigated in greater detail using high frequency sidescan sonar and an Acoustic Resonance Inspection System (ARIS Explorer 3000) camera in a second ten-day survey conducted in August 2020 (https://www.envision.uk.com/wp-content/uploads/2022/03/2018-1008-NRW-WFA-Protecting_Our_Seas_Final_Report_20210201.pdf) The data sets include: SSS (.tif) collected using Trident SeaStar MBES (.xyz) collected using GeoSwath Plus, AGDS (.csv and .asc) collected using RoxAnn™ AGDS ARIS imagery (.png and .mp4) collected using ARIS Explorer 3000 camera Shapefiles (.shp etc)

  • Stress-Dependent permeability data for samples of the Glasgow Main coal and the overlying mudstone and sandstone from the UKGEOS research borehole GGC01. Associated XRD mineralogy, Helium Porosity, bulk and matrix densities are also included. 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.

  • "Three spreadsheet tables of biomarker data, element ratios, and accumulation rates. Sediment samples from IODP Expedition 341, Site U1419 in the Gulf of Alaska. Site U1419 is located in 721 m water depth on the continental slope above the Khitrov basin. Extracted lipids were analysed by HPLC-MS. Two independent methods for bulk element geochemistry analyses were applied to the samples. More details available in the paper Zindorf et al., 2020 https://doi.org/10.1016/j.chemgeo.2020.119864"

  • Organic carbon and bulk nitrogen isotope data for black shale samples from six different drill cores with varying distance from the major Zn ore body (HYC) in the McArthur basin. Data show trends with distance in d15N and C/N ratios. A more detailed interpretation is provided in Stüeken, E.E., Gregory, D.D., Mukherjee, I. and McGoldrick, P., 2021. Sedimentary exhalative venting of bioavailable nitrogen into the early ocean. Earth and Planetary Science Letters, 565, p.116963.

  • Age-depth models for Pb-210 datasets. The St Croix Watershed Research Station, of the Science Museum of Minnesota, kindly made available 210Pb datasets that have been measured in their lab over the past decades. The datasets come mostly from North American lakes. These datasets were used to produce both chronologies using the 'classical' CRS (Constant Rate of Supply) approach and also using a recently developed Bayesian alternative called 'Plum'. Both approaches were used in order to compare the two approaches. The 210Pb data will also be deposited in the neotomadb.org database. The dataset consists of 3 files; 1. Rcode_Pb210.R R code to process the data files, produce age-depth models and compare them. 2. StCroix_agemodel_output.zip Output of age-model runs of the St Croix datasets 3. StCroix_xlxs_files.zip Excel files of the St Croix Pb-210 datasets
