Oxygen-18 isotope ratios from the EPICA Dome C ice core at 11 cm resolution ...
Abstract: We present here a high resolution (0.11 m) dataset of the isotopic composition of the ice (δ¹⁸O) from the EPICA Dome-C ice core. The dataset covers the depth range 7.81-3189.89 m (0.05-802.427 ka). Analysis is performed in Copenhagen with a CO~2~ equilibration Mass Spectrometry system (Fin...
