Varying regional δ18O–temperature relationship in high-resolution stable water isotopes from east Greenland

Christian Holme et al.

Data sets

Seasonally averaged δ18O ice core data (1801-2015 CE) for Renland, Greenland C. Holme

Short summary
This study investigates the linear relationship between the water isotopes of three East Greenland ice cores and regional temperatures. By comparing the water isotopes with nearby instrumental temperature records and reanalysis data, this study demonstrates that it can be problematic to reconstruct temperatures through regression of water isotope data from coastal ice cores. We further show that the varying linear relationship could be connected with changes in sea ice near the drill site.
