Data, icesamples and software
The following data sets are available online from Centre for Ice and Climate, University of Copenhagen. Please refer to the relevant references when using the data.
For other data, please send a data request, including a description of the intended use of the data and a list of which core(s), parameter(s), time span, and resolution are wanted. In the academic season, we aim at answering within one week. During holidays or field season, much longer response times must be expected.
Ice samples for further measurements can also be obtained. Read more about the sampling procedure.

| NGRIP |
GICC05modelext time scale and δ18O values |
Greenland Ice Core Chronology 2005 (GICC05) time scale for the NGRIP ice core (down to 60 ka b2k) extended to the base of the NGRIP ice core by merging with the ss09sea06bm model time scale. The resulting time scale is called GIC05modelext. |
