Large-diameter (24.1 cm) cores (CMC03) drilled with the Blue Ice Drill during PI John Higgins' 2019-2020 field season are currently stored at the NSF-ICF. Smaller diameter (3-inch) cores are also archived. The cores are from the blue ice areas at Allan Hills. For information on the cores available, please contact the NSF-ICF Science Management Office.
