Mechanical and microstructural data from ice deformation experiments with a change in temperature partway

This dataset contains data collected during and after a series of ice deformation experiments. Seven of the experiments are controls, run at a constant temperature of either -2, -7 or -10 degrees celsius, and four involve a change in temperature partway through the experiment. Vertical displacement and temperature data were collected during the experiments, and microstructural data (fabric analyser thin sections) were collected at the conclusion of each experiment. The experimental methods and our interpretations are described thoroughly in: Craw, L., Treverrow, A., Fan, S., Peternell, M., Cook, S., McCormack, F., and Roberts, J. (2021). The temperature change shortcut: Effects of mid-experiment temperature changes on the deformation of polycrystalline ice. The Cryosphere, 15, 1–21. https://doi.org/10.5194/tc-2020-318In folder mechanical_data:- One .csv file for each experiment containing a header with information on experimental conditions, and columns of data corresponding to time (hours), vertical displacement (mm), and temperature (degrees celsius) throughout the experiment. This is raw data, there will be points recorded from before weights were added at the beginning of the experiment, and after the temperature was lowered at the end.in folder microstructural_data:- One .mat file for each experiment, containing microstructural data (spatially indexed Euler orientations) formatted to be read by the MTEX toolbox (https://mtex-toolbox.github.io/). There is also a file for an example of the starting material, "standard" laboratory ice. These data are converted from the .cis files which are generated by the G50 fabric analyser.- One .m script (plot_microstructural_data.m) containing commands for plotting spatial maps, histograms of grain size distribution and pole figures of c-axis orientation from the .mat files in this directory.

本数据集收录了一系列冰体变形实验期间及实验结束后采集的全部数据。其中7组为对照实验，实验温度恒定维持在-2、-7或-10摄氏度，剩余4组实验则在实验中途进行了温度调控。实验过程中同步采集了垂直位移与温度数据，每组实验结束后还采集了显微结构数据（织物分析仪薄片样本）。

在`mechanical_data`文件夹内：
每组实验对应一个.csv格式文件，文件头部包含实验条件相关信息，数据列分别对应实验全程的时间（小时）、垂直位移（毫米）与温度（摄氏度）。该数据为原始采集数据，包含实验初始阶段加载配重前以及实验末期降温后记录的所有测点数据。
在`microstructural_data`文件夹内：
每组实验对应一个.mat格式文件，内含可通过MTEX工具箱（MTEX Toolbox，https://mtex-toolbox.github.io/）读取的显微结构数据（空间索引欧拉取向）。本数据集还附带一份代表实验室标准起始冰体的样本文件。所有数据均由G50织物分析仪（G50 Fabric Analyser）生成的.cis文件转换而来。
此外，该文件夹内还包含一份名为"plot_microstructural_data.m"的.m脚本文件，其中收录了用于绘制该目录下.mat文件的空间分布图、晶粒尺寸分布直方图与c轴取向极图的命令代码。
