General Information
The Beacon Valley and Mullins Valley cores are not "typical" ice cores because of their high mixed ice/sediment content. The cores were collected during the 2004/05, 2006/07, 2008/09, and 2009/10 field seasons. Because of the high sediment content, most of the cores shouldn't be cut in the exam room. The cores were shipped directly from Antarctica to the NSF-ICF and have remained in the main archive freezer since. Metadata for the cores is sparse. See the Beacon/Mullins Valley PDF document for additional information.
If you are interested in the cores, please contact the NSF-ICF Science Management Office.
