Error Notice
Two errors came to NSIDC's attention in the GISP2 core data, found on the Greenland Summit Ice Core CD-ROM, originally released in 1998. 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). Please use the corrected files.
The corrected files are included in this dataset, along with the CD file.
