The GMR is home to the largest, publicly accessible USGS rock core and cuttings collection (the Core Research Center collection). In addition to the large core and cuttings collections, there are over 1,000 pallets of varied materials, from numerous Science Centers and Mission Areas, currently stored in the GMR space.
A variety of samples collected for completed USGS projects are stored in the Geological Materials Repository for possible future use.
The Core Research Center (CRC) was established in 1974 by the U.S. Geological Survey (USGS) to preserve valuable rock cores for use by scientists and educators from government, industry, and academia.
The National Science Foundation Ice Core Facility (NSF-ICF) — formerly the National Ice Core Laboratory (NICL) — is a facility for storing, curating, and studying meteoric ice cores recovered from the glaciated regions of the world.
