This dataset encompasses an Excel datasheet containing aggregate data from thin section analyses of ice samples from the Fimbule Ice Shelf, carried out during the 2021/2022 Antarctic expedition. The research forms a crucial part of the Master's research project: "Development of a Multi-tier System for the Analysis of Ice Crystallography of Antarctic Shelf Ice", conducted by Steven McEwen.

Each entry in the datasheet corresponds to a specific thin section or ice grain and includes the following parameters: Grid Number, A1 Axis Reading, A4 Reading, Corrected A4 values, number of readings, Mean C-axis Orientation, Grain Size, Date, Sample number, x-coordinate, y-coordinate, Degree of Orientation, and Spherical Aperture. These data points collectively facilitate a comprehensive understanding of the crystallography of the Fimbule Ice Shelf's ice samples.

Data was collected and analyzed during the 2021/2022 Antarctic summer expedition, with additional analysis being performed in the Polar engineering Research Group's laboratory.
