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 sites on and near the Greenland summit. The GISP2 (US) site was located at 72 degrees 36 minutes N, 38 degrees 30 minutes W. The GRIP (European) site was located at 72 degrees 35 minutes N, 37 degrees 38 minutes W. A wide range of environmental and physical parameters were recorded from the cores. The data types are listed below:

- Air Mass Trajectories (GISP2)

- Chemistry (GISP2, GRIP)

- Climatological Data (GISP2)

- Cosmogenic Isotopes (GISP2)

- Dust (GISP2)

- Electrical Conductivity (GISP2, GRIP)

- Gas Concentrations in Air Bubbles (GISP2, GRIP)

- Physical Properties and Ice Core Stratigraphy (GISP2, GRIP)

- Stable Isotopes (GISP2, GRIP)

- Time scales (GISP2, GRIP)

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, Boulder 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.

Error notice: Two errors have come to our attention in the GISP2 core data, found on the Greenland Summit Ice Core CD-ROM, originally released in 1998. The corrected files may be found at ftp://adcc.colorado.edu/pub/projects/arcss008/. The dust file, m1650.dat, was missing altogether from the product; the other corrected file is electrical conductivity measurement (ecm) data, d1000.dat. The original d1000.dat file had the same data as the d1100.dat (data for 1100-1149). If you have a copy of this product, please download the corrected files for your use. We apologize for any inconvenience. Contact NSIDC User Services if you have questions.
