Summary
Plots of delta-deuterium against age and depth (from EPICA and Vostok). Note that the Vostok core is deeper, but does not extend as far back in time. Note also that the y-axis offset between the EPICA and Vostok cores in delta-deuterium is real: Vostok is a colder site, hence has more negative delta. Differences in the apparent age of events are likely to be inaccuracies in converting ice depth to age.
