Nanoscopic (50 < size < 150 nm) magnetic particles embedded within the unaltered interior of mineral crystals like zircons (ZrSiO 4 ) make ideal candidates to record the information about the earth's magnetic field (geodynamo). Information regarding the magnitude of the field can be obtained by measuring the natural remnant magnetization (NRM) of these carriers and further information on the approximate size range of the carriers can be obtained by carrying out thermal remnant magnetization measurements (TRM). However very little is known about the actual morphology and spatial distribution of these carriers in order to understand the fundamental parameters influencing paleomagnetic recording. We propose to image pristine zircons crystals with simple geological histories containing large remnant magnetization using ptychotomography in order to investigate the size, shape and spatial distribution of nano-paleomagnetic carriers. This would also give us an opportunity to fine tune the ptychotomographic setup at I13-coherence branch. This data package consists of 3D maps of Bishop Tuff Zircons, relatively young. The folders contain a stack of .tiff files which can be loaded into imagej, dragonfly, aviso for segmentation purposes.

These data represent a series of analyses exploring the seismic behaviours of low-cohesion volcanic sediments – in this case the Neapolitan Yellow Tuff - under varying strain rates. The data include deformation logs from triaxial compression experiments, and the accompanying 12-channel acoustic emission recordings at 10 MHz. These are paired with X-Ray Computed Tomography images of one of the cores from both before and after deformation, to examine damage behaviour. These data include: Deformation logs captured from the triaxial press Acoustic emission event data Processed acoustic emission sonograms for selected events Matlab code for processing of sonograms Matlab code for statistical analysis of the acoustic emission data Before and after X-Ray Computed tomography data for a core which underwent 2% strain at a rate of 4x10-6 s-1. These data relate to Rowley et al - Deformation controlled Long-Period seismicity in low cohesion volcanic sediments https://doi.org/10.31223/osf.io/7rkzv

[This nonGeographicDataset is embargoed until May 1, 2024]. Computed tomography (CT) scans of 212 museum specimens, including mostly cartilaginous and bony fishes as well as several reptiles and amphibians, were obtained to quantitatively study vertebral column morphology and regionalisation. The specimens are housed in the University of Cambridge Museum of Zoology or the Natural History Museum in London (specimen identification numbers can be found in the supporting documentation). These data consist of 1) series of tiff images that can be imported into CT segmenting software to reconstruct their shape in three dimensions; 2) STL files of each vertebra for a subset of the specimens scanned; 3) 3D landmark coordinates or measurements for each vertebra for a subset of taxa scanned; 4) tables of results from regionalisation analyses, and 5) photographs of eight fossil fish specimens Supplemental files include details of the data collection procedures, specimen identification numbers and updated taxonomy, and CT scanning parameters for all scans.

A core scanning dataset from part of the Ellesmere Port-1 drill core that was drilled for unconventional hydrocarbons in 2014. Approximate 40 m of core from the Bowland Shale Formation in the Ellesmere Port-1 (1532.7 – 1663.15 m) was scanned for high-resolution optical images and X-ray fluorescence (XRF) downcore point measurements using the Itrax MC core scanner (Cox Analytical Systems) at the Core Scanning Facility (CSF) at the British Geological Survey. Core scanning was utilised as part of the commission phase of this facility.
