Water stable isotopes (dD, d18O) from EPICA Dome C ice core (Antarctica) (0-800 ka)

We present the full dD of water and d18O of water data at 55 cm resolution on the EPICA Dome C ice core from the near surface (6.6 m) to the bottom (3190 m), hence covering the last 800 ka.The EPICA Dome C ice core has been drilled in Antarctica (-75.1°S; 123.395°E; 3233 m elevation) between 1996 an...

Description
Summary:We present the full dD of water and d18O of water data at 55 cm resolution on the EPICA Dome C ice core from the near surface (6.6 m) to the bottom (3190 m), hence covering the last 800 ka.The EPICA Dome C ice core has been drilled in Antarctica (-75.1°S; 123.395°E; 3233 m elevation) between 1996 and 2004 and measurements performed from 2001 to 2020. Some of the data were already published in previous published studies (Jouzel et al. 2007; Stenni et al. 2001, 2004, 2010) but corrections were performed in the present data file. dD measurements from Jouzel et al. (2007) were obtained using a uranium reduction method. In this new dataset, these results over the last 800 ka are combined with new dD measurements (760 samples) performed over the deepest 418 m using a Picarro L2130-i (cavity ring-down spectroscopy). The d18O measurements presented here were performed using a water-CO2 equilibration method.This dataset goes along with a paper published in Nature Geoscience (Landais et al., 2021).
