De-Accessed Cores

The following cores have been de-accessed from the NSF-ICF inventory. Most of the cores are no longer continuous, and the top and bottom depths shown below are from the original drill logs and not necessarily a reflection of what currently remains in the archive. A funded proposal, and Sample Allocation Committee approval, is not needed to access cores on the de-accession list.

The de-accessed cores typically have poor dating and limited data available. Some of the cores were drilled a long time ago, and some cores do not have good core quality. However, the de-accessed cores can be fantastic for method development. Contact the Science Management Office (nsf.icf.smo at unh.edu) to determine the best core for your research needs.
