| contents | 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 2017 and 2019. 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 for the upper 1340 m of the ice core. The stated depth of the section represents the center of the section. At depths of 138.92 m, 276.88 m, 415.3 m, 514.48 m, 613.3 m, 757.21, 899.94 m, 1062.65 m, 1141.2 m, 1256.98 m, and 1339.75 m the orientation of each crystal in the representitive thin section was measured with the Fabric Analyzer G50 to analyze the internal deformation at those depths. Crystal orientations per sample are represented in eleven c-axes stereo plots from those depths. Stereoplots are not geographically truly orientated due to loss of orientation during ice core retrieval. |
