Data files have .dat extension and can be opened with Notepad or any basic text editor software. Each file contains details of sample name, dimensions (length and diameter). All deformed samples were pre-prepared cylinders of synthetic neighbourite. Each file contains 11 data column as follows: Time (hours); Time (secs); CP (V); Vol (V); Force(V); Temp (V); Disp(V); Euro disp (mm); Furn T (mV); PoreP (mV); Furnace Power where V= Volts, mV= millivolts. The Calibration sheet (specific to the apparatus used) uploaded together with the data files is required to convert V and mV raw data into values of stress, strain, strain rate, confining pressure and temperature.

The data contains numerical model simulations designed to assess the influence of a) a permeable bed on flow structures above and within the pore spaces of a bed and b) a biofilm streamer on the free flow structure. For the former the data relates to a novel Computational Fluid Dynamics (CFD) model that is able to simulate flow both in the boundary layer flow and Brinkman layer. This allows simultaneous predictions of surface and subsurface flow in one numerical scheme. The analysis is applied to undertake a numerical sensitivity experiment to assess how bed permeability influences flow over bed forms typically found in river channels e.g. dunes. For the latter the data simulates flow around biofilm-streamers in the laminar flow regime. Numerical simulations simulate the flapping motion of a single biofilm streamer. The major thrust of the study is to investigate the impact of changing Reynolds number on hydrodynamic characteristics of the ambient flow and the frequency of biofilm oscillation.

Element maps from 5x 10 cm sections generated using the Zeiss Sigma HD Field Emission Gun Analytical SEM at Cardiff University. Maps come from sections within the early Miocene pelagic interval situated directly below the Nicobar Fan succession at IODP Site U1480 in the Eastern Equatorial Indian Ocean (for more information see published report, https://doi.org/10.1016/j.epsl.2017.07.019). These specific sections were chosen to examine the depositional environments associated with transitions from red clays to white chalk, which demonstrate distinct banding at the micro and macro scale.

MFIX (Multiphase Flow with Interphase eXchanges) simulation input files and raw particle output files. Description of files 1. The directory "MFIX_Setup" contains the MFIX simulation input files for the two simulations Exp19 and Exp35. (MFIX input file (input and boundary conditions) *mfx & MFIX subroutines (*f) and geometry *stl) 2. The directory "time-averaged_slices" contain the time-average slices as *vtu files for Exp19 and Exp35 that can be opened using Paraview (open-source software). 3. The directory "depth-averaged and time-averaged data" contains the python code that reads the depth- and time-averaged data. Note the simulations were run with MFIX-20. The two simulation (Exp19 and Exp35) are 3D two-fluid model (TFM) numerical simulations of liquid-particle mixture, where the fluid and particles are saline water and silica particles, respectively. The finite-volume method is used to solve the mass, momentum and energy equations of the two phases and the solid-fluid coupling is done using drag and pressure terms. The MFIX code that is modified from the core code from the Department of Energy (DOE) is all present. The missing core code can be downloaded from the DOE department https://mfix.netl.doe.gov/.

Raw mechanical data from currently unpublished sintering experiments using glass beads in a triaxial pressure vessel as well as porosity, permeability results of sintering under constant (uniaxial) load. These experiments will be submitted for publication in the future. All data were collected from 2021 onwards and analysed at LMU Munich. Synthetic glass bead samples are sintered to a target porosity in a furnace to make uniform (homogeneous) porous glass samples, before being cooled, measured for porosity and permeability and then placed in a furnace either: 1) in a uniaxial press; or 2) a triaxial pressure vessel. In 1) a constant load is applied for 3 or 5h; In 2) a hydrostatic or deviatoric stress is applied for variable amount of time while the permeability evolution is constantly measured. These experiments impart physical changes to the porous samples. All samples porosity and permeability (using constant flow rate and nitrogen as a permeating fluid) are also measured post-experiment. Sintered glass beads act as an analogue for magmas. Understanding the evolution of transient porous network in magmas is key to understanding pore pressure evolution in volcanic conduits, which controls effusive-explosive transitions

This dataset includes numerical simulation data of bottom heated convection in a rotating spherical shell. These numerical models are used to investigate the dynamics of convection in planetary cores. The simulations are performed over a range of thermal forcing and rotation rate [1-3] to study the various dynamical regimes of rotating convection. The dataset includes the simulation states to reproduce the simulations, time-series output of relevant variables from the simulations apart from post-processed diagnostic quantities. Due to large volume of the simulation state files only the initial, final and time averaged files are stored in the dataset in NETCDF format. The simulation diagnostics are provided in text, which includes time series, spatial and temporal averages of various diagnostic quantities (e.g. kinetic energy of convection) and forces to assess the underlying dynamics and heat transfer behaviour. The simulations have been performed using the Leeds Spherical Dynamo code [4], using ARC2, ARC3 and ARC4 HPC system in University of Leeds and the ARCHER and ARCHER2 HPC system.

This dataset contains the acquired distributed acoustic sensing (DAS) and hydrophone datasets from a project investigating the usage DAS at the UK Geoenergy Observatory (UKGEOS) research facility in Glasgow, funded by the UK Unconventional Hydrocarbons (UKUH) small project grant. The UKGEOS site in Glasgow has repurposed an abandoned coal mine to investigate its potential as a heat source and heat sink, and its borehole infrastructure includes pre-installed fibre-optic cables. DAS is a novel seismic monitoring technique that utilizes fibre-optic cables to measure small acoustic and seismic vibrations. Comparable to a very densely spaced hydrophone or geophone array, DAS provides unparalleled data resolution and insights into the subsurface. This dataset provides both active source and passive measurements of DAS at the UKGEOS Site 2 prior to the heat pump installation, providing geophysical baseline measurements of the mine. Alongside the acquired DAS data, data from a hydrophone array co-located to the fibre-optic cable was collected during the active source survey to provide a means of comparison to the DAS.

This dataset comprises ECLIPSE input decks for a 3D reservoir simulation of the CO2 plume at the Sleipner CO2 injection site. This whole reservoir model is an attempt to history match the growth of the plume observed on seismic data. A seismic velocity and density model derived from the 3D reservoir simulation is also included, together with a series of Seismic Unix scripts to create a synthetic seismic section through the Sleipner reservoir model, for comparison with released time-lapse seismic data.
