Allan Hills ALHIC1901 ice core fabric data Cite as Stoll, N. (2026) "Allan Hills ALHIC1901 ice core fabric data" U.S. Antarctic Program (USAP) Data Center. doi: https://doi.org/None. Abstract These data cover four depth regimes from the ALHIC1901 core from the Allan Hills Blue Ice Area, Antarctica. We derived crystal properties such as grain size and preferred orientation of the c-axis (fabric) via an Automated Fabric Analyser (G50 by Russelhead Instruments). These data are useful for understanding the current deformation at the ALHIC1901 site impacting the preserved climate record.
