Abstract:

This repository contains GISP2 ice core (Summit, Greenland) sodium concentrations of the upper ca. 1600 meter section of the core, corresponding to the ca. 11,000 years of the Holocene. The time series is smoothed using a 100-yr Gaussian kernel. The raw data are from O'Brien et al., 1995: Complexity of Holocene Climate as Reconstructed from a Greenland Ice Core.

Event(s):

GISP2-D * Latitude: 72.588000 * Longitude: -38.457000 * Elevation Start: 3203.0 m * Elevation End: 0.0 m * Campaign: * Basis: Sampling/drilling ice * Method/Device: Drilling/drill rig (DRILL) * Comment: The length of the 3-km borehole at the GISP2 site was measured by two completely independent geophysical logging systems, the University of Copenhagen system (UCPH) and the U.S. Geological Survey's temperature system (USGS). Both systems utilized steel logging cables. The depth calibration factor for the UCPH system was determined from the measured length of the GRIP ice core while the USGS system was calibrated using a fiberglass tape measure with a low coefficient of thermal expansion. The accuracy of the depth measurements for both systems is estimated to be 2-3 m at a depth of 3 km. Inclination/azimuth measurements from the UCPH logger have been used to calculate the true vertical depth of the borehole from the measured total slant length. UCPH/true vertical depth (m):3047.8 slant length (m):3056.5 USGS/true vertical depth (m):3047.9, slant length (m):3056.6
