Allan Hills ALHIC1901 ice core 3D bubble parameters Data DOI: https://doi.org/10.15784/602009 Cite as Stoll, N., & Freitag, J. (2026) "Allan Hills ALHIC1901 ice core 3D bubble parameters" U.S. Antarctic Program (USAP) Data Center. doi: https://doi.org/10.15784/602009. Abstract These data cover several depth regimes from the ALHIC1901 core from the Allan Hills Blue Ice Area, Antarctica. We derived several bubble characteristics from 3D Computer Tomography analysis, such as bubble size, elongation (aspect ratio), number density and porosity. These data are useful for understanding the current deformation at the ALHIC1901 site impacting the preserved climate record.
