Top-heavy double-diffusive geodynamo simulations

This dataset contains numerical simulations of bottom-heated, top-heavy double-diffusive geodynamo models in a rotating spherical shell. These models are designed to investigate geomagnetic signatures of possible stratified regions near the top of Earth’s outer core. The simulations span a range of thermal and compositional forcings, enabling the study of how lower-mantle heterogeneities and light element accumulation driven stratification may influence the geomagnetic field. The dataset provides: 1. Simulation state files (final state and time-averaged state) in NetCDF format. Due to the large size of full state outputs, only these two files are included. 2. Time-series outputs of key dynamical variables. 3. Post-processed diagnostic quantities, including spatial and temporal averages, kinetic energy budgets, forces relevant to double-diffusive dynamics [2], and metrics used to assess possible thermally and/or compositionally stratified layers near the core–mantle boundary. 4. Metrics to compare the simulation outputs with the features of geomagnetic field over various timescales. All simulations were produced using the Leeds Spherical Dynamo Code [3] and run on the ARCHER2 high-performance computing system.

Top-heavy double-diffusive rotating convection in a spherical shell

This dataset contains numerical simulations of bottom-heated, top-heavy double-diffusive convection in a rotating spherical shell. These models are designed to investigate convective dynamics in planetary interiors, with a particular focus on processes occurring near the top of Earth’s outer core [1]. The simulations span a range of thermal and compositional forcings, enabling the study of how lower-mantle heterogeneities influence core convection. The dataset provides: 1. Simulation state files (final states and time-averaged states) in NetCDF format. Due to the large size of full state outputs, only these two files are included. 2. Time-series outputs of key dynamical variables. 3. Post-processed diagnostic quantities, including spatial and temporal averages, kinetic energy budgets, forces relevant to double-diffusive dynamics [2]. 4.

EU Project: Publications: CO2QUEST  Impact of the Quality of CO2 on Storage and Transport

Coordinated by Haroun Mahgerefteh at UCL, the EC funded FP7 CO2QUEST project addressed the main challenges associated with determining the optimal composition and purity of CO2 product streams derived from carbon capture systems for enabling its safe and economic transport and storage. The project brought together academics and major stakeholders to perform computational studies backed-up by large-scale experiments aimed at identifying CO2 mixtures that have the most profound impact on the different parts of the CCS chain. The project ran from March 2013 until June 2016, involving 9 partners across Europe, including from Canada and China. It resulted in over 100 peer reviewed journal publications and conference proceedings, three international conferences and several newsletters, receiving the IChemE Highly Commended Global Process Safety Award in 2016. More information about CO2QUEST including its objectives, deliverables and list of publications may be found at: http://www.co2quest.eu/

National (Great Britain) Recharge Model climate change runs - 11 regional climate models

The data are the gridded recharge values obtained from the BGS distributed recharge model (ZOODRM) driven by 11 Ensembles of the HaDCM3 Regional Climate Model (RCM) taken from the Future Flow and Groundwater Level data set (http://www.ceh.ac.uk/our-science/projects/future-flows-and-groundwater-levels). The model covers the mainland areas of England, Scotland and Wales. The 11 ensembles are run from January 1950 to December 2099. The dataset themselves are the gridded (2 km by 2 km) outputs from the recharge model averaged over four time horizons: historical, 20s, 50s, and 80s, for each of the 11 ensembles. The results can be used to assess the impact of climate change on potential recharge (soil drainage) for catchments in mainland England, Scotland and Wales.

Foraminifera-based data spanning several tephra horizons in cores from IODP Leg 350, sites U1436 and U1437 (NERC grant NE/M005232/1)

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.

Ground control points for investigating mass loss processes on Khumbu Glacier, Nepal (NERC grant NE/L002574/1)

These data consist of a spreadsheet containing 557 ground control points (GCPs) collected in the Everest region of Nepal between October 2015 and October 2016. GCPs were collected using a Leica GS10 differential Global Positioning System (dGPS), post-processed against base station data at Syangboche. These final data have sub-centimetre accuracy (in x, y and z) in all cases. Point positions are heavily concentrated around meltwater ponds on the glacier surface, and prominent features around the glacier margin. These data will be used by PhD students and staff in the School of Geography, University of Leeds, to provide ground control for fine-resolution satellite imagery and Structure-from-Motion surveys to assess mass loss processes on Khumbu Glacier.

Fe-X-ray Absorption Near Edge Spectroscopy (Fe-XANES) spectra from clinopyroxene powders and crystals with known and unknown Fe3+/FeTotal contents with supporting major element compositions from EPMA and crystal orientation data from EBSD

Fe-X-ray Absorption Near Edge Spectroscopy (Fe-XANES) spectra from clinopyroxene powders and crystals with known and unknown Fe3+/FeTotal contents with supporting major element compositions from electron probe microanalysis (EPMA) and crystal orientation data from electron backscattered diffraction (EBSD). These data were collected in support of an article titled: 'Estimating Fe valence in magmatic clinopyroxene crystals: Fe-XANES versus electron microprobe'. Clinopyroxene crystals with known Fe3+/FeTotal contents were sourced from collections at the University of Manchester and Manchester Museum, and have been described previously by Neave et al. (2024a; doi: 10.1007/s00410-023-02080-2). Clinopyroxene crystals with known Fe3+/FeTotal contents are from Skuggafjöll (Iceland) and Pico Island (Azores) and have been described previously by Neave et al. (2024b; doi: 10.1007/s00410-024-02144-x). These data were acquired as part of David A. Neave's NERC IRF (NE/T011106/1) between January 2020 and February 2023. Fe-XANES was performed at Diamond Light Source Beamline I18 (SP31428) in February 2023. EPMA was performed at the University of Bristol in Spring 2022. Electron Backscattered Diffraction (EBSD) was performed the University of Liverpool in May 2023. These data were collected to evaluate whether Fe-XANES, which has seen increasingly widespread use for determining Fe valence in isotropic glasses and minerals in recent years, could be routinely used to determine Fe valence in large numbers of anisotropic clinopyroxene crystals. Our motivation stems from ultimately seeking to develop new tools for estimating oxygen fugacity from magmatic clinopyroxene crystals. This work was initially designed to capitalise on two articles on clinopyroxene Fe-XANES that have since been retracted without further comment; we thus present an evaluation that transparently highlights the myriad challenges associated with clinopyroxene Fe-XANES.
