The NICL Inventory describes the ice core holdings of the National Ice Core Laboratory (NICL), a facility for storing, curating, and studying ice cores recovered from the world's polar regions. It is jointly operated by the U.S. Geological Survey, the U.S. National Science Foundation, and the University of Colorado (USA) Institute of Arctic and Alpine Research. NICL ... is located in the Denver Federal Center complex (Lakewood, Colorado, USA). The information provided in this inventory is designed to allow research scientists a convenient listing of potential research samples. The inventory is available via FTP from NGDC (World Data Center A-Paleoclimatology) in cooperation with National Snow and Ice Data Center (World Data Center A-Glaciology). The NICLsite files provide a summary listing of core sites and samples curated by NICL. The individual drillsite files provide detailed information on the size and condition of individual samples stored at the NICL facility. The National Ice Core Laboratory (NICL) Inventory covers the period of record from the present back to approximately 160,000 YBP. Cores at NICL include LITTLE AMERICA V 1958 from ANTARCTICA, CAMP CENTURY cores from 1961 to 1966 from GREENLAND, BYRD STATION 1968 and 1971 from ANTARCTICA, DYE-3 of 1971 and 1979-81 and DYE-2 of 1977 from GREENLAND, MILCENT of 1973 from GREENLAND, CRETE of 1974 from GREENLAND, J-9 BERN of 1976 and J-9 of 1978 from ANTARCTICA, SITE A CORE1 of 1985 from GREENLAND, SITE A CORE 2 of 1985 from GREENLAND, GISP2 CORES B, C, D, E, G1, and G2 of 1989-1992 from GREENLAND, the VOSTOK core of ANTARCTICA, and the McMURDO DOME core of ANTARCTICA.

Files available from NGDC about NICL ice cores include : NICLsite - tab-delimited ASCII file of site information on NICL cores, including the core number, SiteName, Location, Lat and Long, MinDepth, Max Depth, Elev., Core Dia., # Tubes in Inventory, Total Tubes, Drill Meth., and Tube Length
NICLsite.xls files - Excel files containing the same site information
32 sitenamed inventory files containing detailed inventory information on each core, one or more files per core, including core quality, samples taken, %remaining, breaks, etc.
The files will be updated periodically to reflect the changing inventory as new cores come in and old cores are consumed.
