Allan Hills ALHIC1901 ice core 2D bubble parameters Cite as Stoll, N., & Fudge, T. J. (2026) "Allan Hills ALHIC1901 ice core 2D bubble parameters" 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 several 2D bubble characteristics from analysing stinted images of ice sample thin sections, such as bubble size and elongation (aspect ratio) These data are useful for understanding the current deformation at the ALHIC1901 site impacting the preserved climate record.
