Abstract:
1-day age-depth resolution snow core isotope data (dD, d18O, dxs, dxsln) from EastGRIP, Greenland. An age-depth model has been applied based on when peak monthly temperatures occur. In the absence of constrained peak temperatures, a manual assignment of end date for the core was made based first on the mean accumulation for the relevant time period was used for the age-depth model and then the likely timing of the final d18O values.
