(2024) "ALHIC2201 and ALHIC2302 3D ECM and Layer Orientations" U.S. Antarctic Program (USAP) Data Center. doi: https://doi.org/None. Abstract This dataset includes three-dimensional multitrack electrical conductivity measurements (3D ECM) results from measurements in the upper sections of the ALHIC2201 and ALHIC2302 large (241mm) diameter ice cores drilled in the Allan Hills blue ice area (76.73°S,159.36°E) in Victoria Land, East Antarctica. The data extends from the surface to 23.0 m depth in ALHIC2201 and from 8.5 m to 46.3 m depth in ALHIC2302. We include the raw 3D ECM data (AC and DC multitrack ECM measurements on perpendicular faces of a quarter-core cut) in CSV format and basic plots of this data. We also provide dip and dip direction estimates of the layering observed in each core section in a CSV table.
