British Geological Survey (BGS) Geochemical and Sampling Survey S1/72/02: Bristol Channel: Gamma Spectrometer (16/Sep/1972 to 01/Oct/1972)

This marine geochemical and sampling survey undertaken by Istititute of Geological Sciences (BGS) in conjuction with AERE, Harwell took place September to October 1972 in the Bristol Channel on m.v. Observer. This involved calibration of a sea-bed gamma spectometer towed over an area of relatively well known geology north-east of Lundy with subsequent work in the lesser known area of Bridgwater Bay. In the latter area, gravity cores were taken to calibrate the spectometer.

Experimental logs and analysis of olivine polymorphs and MORB (Mid-Ocean Ridge Basalt) composition garnetite samples recovered from high-pressure faulting experiments

Multi-anvil experiments were performed both in static and deformation geometries on olivine polymorphs and MORB (Mid-Ocean Ridge Basalt) -composition garnetite. Faults were induced by uniaxial compression in both garnetite and wadsleyite but only the garnetite showed evidence of thermal run away to melting. These results suggest that strain localisation by thermal feedback might be an important mechanism for triggering deep earthquakes in the crustal portion of subducted slabs in the deeper transition zone (~500-660 km depth).

Aragonite precipitation rates from seawater of variable pH, saturation state, biomolecule composition and temperature

Precipitations were conducted using a pH stat titrator using the constant composition technique between August 2020 and April 2022. Aragonite precipitation rates are estimated from the rate of titrant dosing. pH and DIC are used to estimate the seawater aragonite saturation state of each precipitation and, on occasion, the [HCO3-] and [CO32-]. Data were collected to determine how changes in the calcification fluids of calcareous organisms affect aragonite precipitation. Data were collected by Cristina Castillo Alvarez and interpreted by Cristina Castillo Alvarez, Nicola Allison, Adrian Finch, Kirsty Penkman, Roland Kröger and Matthieu Clog.

Nanoindentation, high-angular resolution electron backscatter diffraction (HR-EBSD), and transmission electron microscopy data in synthetic forsterite bicrystal samples (NERC Grant NE/S00162X/1)

The data are nanoindentation, high-angular resolution electron backscatter diffraction (HR-EBSD), and transmission electron microscopy data collected on samples of synthetic forsterite bicrystals at room temperature. The data were collected in two samples, with high- and low- angle grain boundaries (HAGB, 60°, [100]/(011) and SB, 13°, [100]/(016)). The EBSD data are the basis for the HR-EBSD calculation. The HR-EBSD results are presented as Matlab data files. The nanoindentation data are categorised as a function of sample (‘ol13’ – low-angle grain boundary; and ‘ol60’ – high-angle grain boundary), and indenter tip geometry (spherical (with a 10 or 5 micron radius) and pyramidal (Berkovich). The data are presented in .xls files. The TEM data are presented as .tif files. The TEM data were collected in specific indents with various distances from the interfaces. These data have been published in the manuscript: : The Role of Grain Boundaries in Low-Temperature Plasticity of Olivine Revealed by Nanoindentation, with the DOI: 10.1029/2023JB026763

Rheometry data on ash from Mount Meager, British Columbia, Canada (NERC Grant NE/W003767/1)

Rheometry data on ash from Mt Meager, British Columbia, Canada. All measurements that generated these data were performed using an Anton Paar MCR302 rotational rheometer with an Anton Paar powder flow cell attached. The rotating measuring geometry is 24.16 mm in diameter and contains 20 evenly spaced depressions of 1.75 mm that extend the entire length of the measuring cylinder. The profiled nature of this geometry prevents particle slip during rotation. Shear rate sweeps were performed to characterise the rheological behaviour of our pyroclast-gas mixtures. ~50 g of sample (ash from Mt Meager, British Columbia, Canada) was loaded into the powder flow cell with the measuring geometry inserted. Then for a constant gas flux applied to the base of the powder flow cell, the measuring geometry was rotated to apply a range of shear rates starting at 0.1 s-1 ramping up to 328 s-1 with approximately 20 data points generated per decade. These shear rate sweeps were performed for monodisperse grain sizes from 500 µm to 63 µm at a range of volumetric gas flow rates. Specifically for the 500 µm sample the rheology experiments were performed at 0, 15, 30, 45, 50, 55, 60, 65, and 70 L min-1. For the 250 µm sample the rheology experiments were performed at 0, 15, 20, 25, 30, 35, and 40 L min-1. For the 125 µm sample the rheology experiments were performed at 0, 1, 2, 3, 4, 5, 7, 8, 9, and 10 L min-1. For the 63 µm sample the rheology experiments were performed at 0, 0.25, 0.5, 1, 1.5, 2, 3, 4, and 5 L min-1.
