Observational fabric (c-axis distribution) data was retrieved from a shallow firn core on the southeast shear margin of NEGIS called S5. The preparation and measurement of the samples follow the principles as described by Weikusat rt al. (2017). All analysed samples are vertical to the ice core axis and have dimensions of about 90 x 70 x 0.3 mm. The sample surfaces were carefully polished with a microtome in the EGRIP trench at -18 °C. After one hour of controlled sublimation, c-axes were measured with an automated fabric analyser by Russel-Head Instruments (FA G50). The data was background corrected before processing, and the Crystal preferred orientation CPO was derived via digital image processing. We here show data of three S5 shallow core samples from a depth of 68 m.
