Mean ice grain size and crystal-preferred orientation data was obtained from vertical thin sections (ca. 6.7 x 9 cm²) of the East Greenland Ice Core Project (EGRIP) ice core to analyze the microstructural evolution and internal deformation with depth. Vertical ice thin sections were prepared and measured with the Fabric Analyzer G50 (resolution: 20 μm/pixel) in the field at the EGRIP site in the summer seasons between 2018 and 2019, and at the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research. 55 cm long sample were cut into six thin sections and used to calculate mean grain size values for these 9 cm long sections with the program cAxes between 1340 and 2121 m of depth. The stated depths of the section represent the top, center, and bottom of the section.
