We here describe, document, and make available a wide range of data sets used for annual-layer identification
in ice cores from DYE-3, GRIP, NGRIP, NEEM, and EGRIP. The data stem from detailed measurements
performed both on the main deep cores and shallow cores over more than 40 years using many different
setups developed by research groups in several countries and comprise both discrete measurements from cut ice
samples and continuous-flow analysis data.
The data series were used for counting annual layers 60 000 years back in time during the construction of
the Greenland Ice-Core Chronology 2005 (GICC05) and/or the revised GICC21, which currently only reaches
3800 years back. Now that the underlying data are made available (listed in Table 1) we also release the individual
annual-layer positions of the GICC05 timescale which are based on these data sets.
We hope that the release of the data sets will stimulate further studies of the past climate taking advantage of
these highly resolved data series covering a large part of the interior of the Greenland ice sheet.
