O2 triple isotope record from the Allan Hills, Antarctica, ranging from 500 - 2800 ka Cite as Banerjee, A., & Yan, Y. (2026) "O2 triple isotope record from the Allan Hills, Antarctica, ranging from 500 - 2800 ka" U.S. Antarctic Program (USAP) Data Center. doi: https://doi.org/None. Abstract This dataset contains triple isotopic composition of atmospheric O2. Samples come from the ALHIC1901 ice core from the Allan Hills, Antarctica. Additional O2 triple isotope data from previous measurements in the ALHIC1502 and ALHIC1503 ice core is also reported.
