The Greenland Summit Ice Cores CD-ROM

From 1989 to 1994, the U.S. and European scientific communities supported a bold undertaking to acquire an extensive paleoclimate record for the Northern Hemisphere. These efforts, termed the Greenland Ice Core Project (GRIP) and Greenland Ice Sheet Project Two (GISP2), acquired deep ice cores from on and near the Greenland summit. A wide range of environmental and physical parameters (ecm, ions, isotopes, etc.) were measured in each of the cores along with present day meteorological conditions. These data provide information that has helped investigators piece together past environmental changes which could shed light on possible future scenarios. The GISP2 site was located at 72^o 36' N, 38^o 30' W. The GRIP site was located at 72^o 35' N, 37^o 38' W.

The table of contents of this CD-ROM provides ice core information from the Greenland Ice Sheet Project Two (GISP2) and the Greenland Ice Core Project (GRIP) efforts. Searching and graphing (Macintosh and PC only) capabilities are additional features included with this product. This CD-ROM was created in conjunction with the Journal of Geophysical Research (JGR) Joint Issue (Atmospheres and Oceans) on the Greenland Ice Cores, 1997, vol. 2. Please refer to the JGR publication for articles about the data and information included here. A bibliography of the JGR Joint Issue authorship and article information can be found in the table of contents.

The GRIP and GISP2 data presented on this CD-ROM were acquired as a part of a multi-institutional effort involving the GISP2 Science Management Office (SMO) at the University of New Hampshire, the Arctic System Science (ARCSS) Data Coordination Center (ADCC) at the National Snow and Ice Data Center (NSIDC), the International Ice Core Data Cooperative (IICDC) at the Institute of Arctic and Alpine Research (INSTAAR), and the World Data Center (WDC) for Paleoclimatology at the NOAA National Geophysical Data Center (NGDC).

Documentation, CD-ROM format and structure, artwork and data format were carried out jointly by NSIDC and the WDC for Paleoclimatology. All GISP2 and GRIP data are jointly archived at the ADCC at NSIDC and at the WDC for Paleoclimatology, NOAA-NGDC.

Updated in this version:
Two new files have been added since the original 1998 release of the Greenland Summit Ice Cores CD-ROM. The dust file, m1650.dat, was added as it was missing from the original release. A corrected electrical conductivity measurement (ecm) data file, d1000.dat, was also added. The original d1000.dat file had the same data as the d1100.dat (data for 1100-1149).
