Data for: Grain growth of natural and synthetic ice at 0 ºC
Description
This repository includes electron backscatter diffraction (EBSD) data collected from ice samples. The EBSD data were collected using a Zeiss Sigma VPFEGSEM combined with a Symmetry EBSD camera from Oxford Instruments. We collected these data at the University of Otago.

Steps to reproduce
We prepared the surface of ice slices and collected cryo-EBSD data from ice surfaces following the procedures described by Prior et al., (2015). We polished the sample surface by hand lapping on grit papers with grit sizes of 80, 240, 600, 1200 and 2400 at -40°C. The EBSD data were collected using a Zeiss Sigma VPFEGSEM combined with a Symmetry EBSD camera from Oxford Instruments. EBSD data were acquired at a stage temperature of∼−95ºC, with 2–5 Pa nitrogen gas pressure, 30 kV accelerating voltage, a beam current of∼60 nA, and a step size of 30 µm. For Priestley ice samples, secondary electron images were collected simultaneously with EBSD data. Prior, D.
