This study examines the dietary adaptability of European grey wolves using dental microwear texture analysis (DMTA).

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 &amp; 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.</gco:CharacterString>\r\n      </gmd:abstract>\r\n      <gmd:pointOfContact>\r\n

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.","language":{"code":"eng"},"languages":[],"created":"2025-10-31T00:00:00Z","updated":"2026-03-19T00:00:00Z","type":"catalog","keywords":["NERC_DDC","NGDC Deposited

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.</gco:CharacterString>\r\n

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).","language":{"code":"eng"},"languages":[],"created":"2025-10-24T00:00:00Z","updated":"2026-03-19T00:00:00Z","type":"catalog","keywords":["NERC_DDC","NGDC Deposited Data","Density","Volcanic glass","Geology"],"themes":[{"concepts":[{"id":"NERC_DDC"}],"schema":"otherKeywords-"},{"concepts":[{"id":"NGDC Deposited Data","url":"https://webapps.bgs.ac.uk/services/ngdc/accessions/index.html"}],"schema":"otherKeywords-dataCentre"},{"concepts":[{"id":"Density"},{"id":"Volcanic glass"}],"schema":"BGS Thesaurus of Geosciences"},{"concepts":[{"id":"Geology","url":"https://inspire.ec.europa.eu/theme/ge"}],"schema":"GEMET -

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.

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 &amp; 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.</gco:CharacterString>\r\n      </gmd:abstract>\r\n      <gmd:pointOfContact>\r\n        <gmd:CI_ResponsibleParty>\r\n          <gmd:individualName>\r\n            <gco:CharacterString>Amanda

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).

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?

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).

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.</gco:CharacterString>\r\n          </gmd:statement>\r\n        </gmd:LI_Lineage>\r\n      </gmd:lineage>\r\n    </gmd:DQ_DataQuality>\r\n  </gmd:dataQualityInfo>\r\n</gmd:MD_Metadata>"}},{"id":"9df8df52-d6b2-37a8-e044-0003ba9b0d98","conformsTo":["http://www.opengis.net/spec/ogcapi-records-1/1.0/req/record-core"],"time":{"interval":["1996-03-01T00:00:00.000Z","1999-02-01T00:00:00.000Z"]},"type":"nonGeographicDataset","properties":{"title":"An Experimental Study of the Stability of Hydrous Phases at High Pressures Implications for H2O Storage and Release in Subduction Zones","description":"PROJECT DETAILS ONLY - NO DATA.

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 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.</gco:CharacterString>\r\n      </gmd:abstract>\r\n      <gmd:pointOfContact>\r\n
