Dental Microwear Texture Analysis (DMTA) of tooth surfaces of fossil wolves from Britain and modern wolves from Poland version 2
Two Excel workbooks reporting dental microwear texture analysis (DMTA) raw data. These are values from scale-sensitive fractal analysis (SSFA), and areal surface texture analysis (based on a suite of parameters, most of which are defined by ISO-25718-2) for dental microwear texture analysis of tooth surfaces of wolves from Britain (MIS Se & MIS 7 a-c) and modern Poland wolves. This study examines the dietary adaptability of European grey wolves using dental microwear texture analysis (DMTA). These datasets offer new insights into the palaeoclimatic and palaeoenvironmental conditions under which grey wolves endured climate change in the past, free of anthropogenic influence. They further allow the identification of hitherto-hidden ecological stress today, thereby highlighting potential vulnerabilities in modern populations under current and future climate change. Tooth surface casts were produced using high-resolution, which is optimised for imaging purposes. Epoxy tooth replicas were scanned with a Sensofar S neox. MountainsMap Imaging Topography was utilised to quantify dental microwear texture parameters from Sensofar scans.

Tooth surface casts were produced using high-resolution, which is optimised for imaging purposes. Epoxy tooth replicas were scanned with a Sensofar S neox. MountainsMap Imaging Topography (version V10, Digital Surf, Besançon, France) was utilised to quantify dental microwear texture parameters from a Sensofar S neox profiler. The scan processing protocol comprises: 1) levelling with least squares plane (LSPL) to correct surface inclination, 2) threshold application to eliminate the upper and lower 0.1% of data, 3) filling of non-measured points using the smooth shape calculated from neighbours function, 4) surface point retouching followed by smooth shape fill of missing data points, 5) level again for generating SSFA parameters, 6) form removal with polynomial of degree – 2 (7) spatial filtering (robust Gaussian, order 0 (ISO 16610-71); with a cut-off value of 0.025 ?m) for generating areal texture parameters.
Data for the H2O concentration in glass particles produced during the 2011-2012 Cordon Caulle eruption.
These are data pertaining to Wadsworth et al. (2022) which are published here: https://doi.org/10.1016/j.jvolgeores.2022.107672. How: Samples were set in epoxy and ground to the point where half of the glass chips collected were ground away. Then the sample was turned around and the other half of the particles were ground away until a thin slice of the chips remained at about 0.05 mm thick. At this point, the thin slices of volcanic chips were measured using Fourier Transform Infrared How: Spectroscopy (FTIR) at JAMSEC (Japan) by Iona McIntosh in collaboration with coauthors and Fabian Wadsworth. The data are the primary data in this manuscript. These data were collected to investigate how much water is remnant in particles that are known to have formed by the competition between degassing of H2O and sintering in volcanoes. That competition has implications for the development and destruction of permeability, which is at the core of this project.
The data were collected at JAMSTEC (Japan) by Iona McIntosh in collaboration with Fabian Wadsworth as part of this project. The data were analysed on samples collected in Chile at the site of the 2011 eruption of Cordon Caulle (40°35′25″S 72°07′02″W / 40.59028°S 72.11722°W). The data were collected in 2021 ahead of publication in 2022. The data were collected by the authors involved directly and have been made available with the publication. Other than that, the data have not exchanged hands or been subject to any other changes.
Data on glass chips from IDDP-1 (Iceland) drilling project
These are so-called relaxation datasets for the rate of structural relaxation of glass exposed to high temperatures. The glass is in the form of chips collected during the IDDP-1 drilling project at Krafla Iceland (more below). The chips were generated during drilling in 2011. However, the analysis presented here was developed in 2023 ahead of the ultimate publication in 2024. The data were collected using differential scanning calorimetry, which is a standard method in glass science for measuring the enthalpy of glass relaxation as it is returned to the high temperatures from which it formed. The relaxation rate of the glass from IDDP-1 tells us directly what the rate was at which it cooled. That "cooling rate" in turn allows us to understand what the time available for fragmentation and sintering in geothermal systems is, which has informed this wider project.
The data were collected by the authors involved directly and have been made available with the publication. Other than that, the data have not exchanged hands or been subject to any other changes. These data were collected at LMU (Munich, Germany). The data are from IDDP-1 in Iceland which is at these coordinates: 65.71587° N, 16.76452° W.
Volume and density measurements for obsidian
This dataset contains Volume and density measurements for obsidian using helium pycnometry. The data was collected and analysed at the University of Liverpool for cored rhyolitic obsidian cylinders from Hrafntinnuhryggur, Iceland. The geographical location of the samples is here inconsequential for the dataset; the specific obsidian was chosen for its physical properties alone. The sample mass (using a scale) and geometry (using a caliper) of 7 representative samples of rhyolitic obsidian was measured, and the samples were analysed using a helium pycnometer, which measures volume, and correspondingly density when the sample mass is provided. The density of the rhyolitic obsidian was needed for the experiments in the study Seropian et al (2022).
The mass and geometry are direct measurements. The helium pycnometer outputs the measured volume (and correspondingly density when the sample mass is provided), and there is no further treatment of the data.
Dental Microwear Texture Analysis (DMTA) of tooth surfaces of fossil wolves from Britain and modern wolves from Poland
This dataset has been superseded, the latest version is version 2, http://data.bgs.ac.uk/id/dataHolding/13608613 Dental microwear texture analysis (DMTA) raw data. These are values from scale-sensitive fractal analysis (SSFA), and areal surface texture analysis (based on a suite of parameters, most of which are defined by ISO-25718-2) for dental microwear texture analysis of tooth surfaces of wolves from Britain (MIS 5e & MIS 7 a-c) and modern Poland wolves. This study examines the dietary adaptability of European grey wolves using dental microwear texture analysis (DMTA). We compare modern Polish wolf populations from the present interglacial (Holocene), with fossil specimens from two contrasting Pleistocene interglacials: the warmer Last Interglacial (Marine Oxygen Isotope Stage [MIS] 5e) and the cooler Penultimate Interglacial (MIS 7a–c). These datasets offer new insights into the palaeoclimatic and palaeoenvironmental conditions under which grey wolves endured climate change in the past, free of anthropogenic influence. And allows the identification of hitherto-hidden ecological stress today, thereby highlighting potential vulnerabilities in modern populations under current and future climate change.

Tooth surface casts were produced using high-resolution, which is optimised for imaging purposes. Epoxy tooth replicas were scanned with a Sensofar S neox. MountainsMap Imaging Topography was utilised to quantify dental microwear texture parameters from Sensofar scans. Nonparametric statistical tests were used on untransformed raw data for analysis. Our hypotheses were tested using Wilcoxon two-sample tests for comparisons between two groups, or Kruskal-Wallis tests between three groups. Nonparametric Steel-Dwass pairwise tests were used following Kruskal-Wallis tests to test for significant differences between pairs of groups. PCA was used to test whether Pleistocene (MIS 5e and MIS 7a-c) and modern wolf groups (Poland) occupied statistically different areas of multivariate texture-dietary space.
Major element, trace element and Nd isotopes of cumulate plagioclase and clinopyroxene in lower crustal gabbros from Hess Deep oceanic crust, East Pacific Rise, with elemental maps of all studied samples
We collected major element, trace element and Nd isotopes of cumulate plagioclase and clinopyroxene in lower crustal gabbros from Hess Deep oceanic crust (~2°15'N, 101°30'W) to investigate the Nd isotopic heterogeneity of melts delivered to a complete section of Hess Deep oceanic crust, accreted at the fast-spreading (133 mm/yr) East Pacific Rise (EPR). These data are presented in Cooper et al. (2025) (https://doi.org/10.1130/G52872.1). Elemental maps of 58 samples were initially obtained prior to selecting a subset of 25 samples for in-situ microanalysis. We targeted the Nd isotope record of cumulate plagioclase and clinopyroxene from lower crustal gabbro samples, representing early crystallisation products of melts delivered to the crust. These samples were collected in several expeditions: Ocean Drilling Program (ODP) Leg 147; RSS James Cook cruise JC21; Integrated Ocean Drilling Program (IODP) Expedition 345 (Site U). Combined, these studies provide the most complete composite section of fast-spreading EPR crust to date (stratigraphic depth of 4350 m to 25 m). In our study, we selected 25 samples for in situ Nd isotope microanalysis, covering the range of mineralogy and textural diversity, and over the full stratigraphic depth. For a comparison to local MORB compositions, we selected a set of 13 upper-crustal sheeted dikes collected on the RSS James Cook cruise JC21. Our data reveal that the mantle is heterogeneous at the scale of melt extraction, and the crystal record from the lower crust shows greater 143Nd/144Nd heterogeneity than the overlying MORB. Hence, Pacific MORBs do not reflect the full heterogeneity of their mantle source, and some aggregation of melts occurs within the crust. Data was collected between 2020 and 2023 by George Cooper, Johan Lissenberg and Max Jansen at Cardiff University, UK, as part of NERC Grant NE/T000317/1:HiDe: A Highly Heterogeneous Depleted Upper Mantle? Mineral isotopic analyses were performed on a Thermo Scientific TRITON Plus at the Vrije Universiteit in Amsterdam. The long-term average and reproducibility (2019–2022) for the JNdi-1 standard is 0.512094 ± 0.000011 2 SD (standard deviation; n = 28) with 1011Ω resistors (used for clinopyroxene) and 0.512105 ± 0.000044 2 SD (n = 45) with four 1013Ω resistors (used for plagioclase).

Elemental maps of all studied samples were carried out on a Zeiss Sigma HD field emission gun scanning electron microscope (SEM) at Cardiff University, UK. Mineral trace element concentrations were measured by laser ablation–inductively coupled plasma–mass spectrometry (LA-ICPMS) (Applied Spectra Inc. RESOlution S-155 laser coupled to an Agilent 8900 ICP-QQQ). Nd concentrations were used to predetermine the sample volume needed to be recovered from micromilling. Typical Plagioclase and Clinopyroxene cores from each sample were drilled using a New Wave™ Research MicroMill. Milled powders were digested in HF and HNO3 prior to Nd separation by column chemistry. Mineral Isotopic analyses were performed on a Thermo Scientific TRITON Plus at the Vrije Universiteit, and whole-rock dike samples were measured on a Nu plasma II multicollector ICP-MS at Cardiff University.
An Experimental Study of the Stability of Hydrous Phases at High Pressures Implications for H2O Storage and Release in Subduction Zones
PROJECT DETAILS ONLY - NO DATA. To determine the p-t stability of hydrous phases in ultramafic compositions in subduction zones, and the conditions at which h2o is released from subducting slabs in dehydration reactions; to obtain thermodynamic data for hydrous phases through phase-equilibrium experiments and in situ volume measurements; and to constrain the equation of state of h2o at high pressures. Reversed phase-equilibrium experiments will be conducted on reactions in the systems mgo-sio2-h2o and mgo-al2o3-sio2-h2o; thermodynamic data for hydrous phases wil be extracted from p-t postions of solid-solid reactions; positions of dehydration reactions will constrain the equation of state of h2o; volumes of phases will be measured in situ using synchrotron radiation

Combined Detrital Geochronology and Provenance Studies of Cretaceous-Paleoecene Sediments from the Faroe-Shetland Basin
Classical provenance study techniques will be extended using Ar-Ar dating of individual detrital micas to examine the link between source uplift, erosion and sediment supply in the pivotal area west of Shetland. The work has economic significance in that it places constraints on the location of sediment entry points, intrabasinal sand body distribution, and reservoir quality, all issues of importance to the hydrocarbon industry. This scoping study is intended to test the combination of techniques in an area where the source is well characterised, and may form an analogue for rifting between Africa and South America. The importance of the work in the area is reflected by the industry backing for this project.

Integrated Seismic and Subsidence Analysis of Conjugate Margin Systems in the Eastern Black Sea - Reports (NER/T/S/2003/00114 and NER/T/S/2003/00885)
Developing Hydropyrolysis to Generate Molecular Biomarker Signals for Solving Key Problems in Oil Exploration Where Conventional Biomarkers Fail - Final Report
The aim is to realise the potential of hydropyrolysis (pyrolysis assisted by high hydrogen gas pressures) as a means to provide reliable molecular fingerprints for severely biodegraded oils, contaminated cores, oil-field solids (tar mats and pyrobitumens) and to provide novel information on basin filling history where the conventional free biomarker approach fails. This will then facilitate rapid and accurate oil-source and oil-oil correlations to be determined for the first time in Ocean Margin regions. The study will establish a firm base to exploit the commercial potential of hydropyrolysis, both in terms of oil exploration through the new correlations with bound biomarker profiles and of characterising sedimentary organic matter as a far superior technique to py-GC-MS. Indeed, innovative experimental protocols for conducting hydropyrolysis will continue to be developed to have a proto-type system ready for future exploitation.
