Summary/Abstract:
A high-resolution deuterium profile is now available along the entire European Project for Ice Coring in Antarctica Dome C ice core, extending this climate record back to marine isotope stage 20.2, ~800,000 years ago. Experiments performed with an atmospheric general circulation model including water isotopes support its temperature interpretation. We assessed the general correspondence between Dansgaard-Oeschger events and their smoothed Antarctic counterparts for this Dome C record, which reveals the presence of such features with similar amplitudes during previous glacial periods. We suggest that the interplay between obliquity and precession accounts for the variable intensity of interglacial periods in ice core records.
Study Notes:
High-resolution (55cm.) deuterium (dDice) profile from the EPICA Dome C Ice Core, Antarctica (75º 06' S, 123º 21' E), with an optimal accuracy of ± 0.5 ‰ (1 sigma), from the surface down to 3259.7 m. LAST UPDATE: 11/26/2007 (Replaced age model. This file now includes EDC3 age model. Previous version of this file dated 10/16/2007 erroneously included the older EDC1-EDC2 age model).More Information:
