Abstract:
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.
