Common millennial-scale variability of Antarctic and southern ocean temperatures during the past 5000 years reconstructed from the EPICA Dome C ice core
Measurements of the two water stable isotopes (dD and d18O) along EPICA (European Project for Ice Coring in Antarctica) Dome C ice core are combined with simple isotopic modelling (distillation models) to reconstruct the variability of both the site temperature (East Antarctica) and the moisture sou...
