Large-diameter (24.1 cm) cores drilled with the Blue Ice Drill are stored at the NSF-ICF. Smaller diameter (3-inch) cores are also archived. The cores are from the blue ice areas at Allan Hills. The Center for Oldest Ice Exploration (COLDEX) is managing access to the Allan Hills ice cores archived at the NSF-ICF, including the Allan Hills cores collected prior to the COLDEX STC funding. For information on the Allan Hills cores available, please contact COLDEX at coldexinfo at oregonstate dot edu.
