Dansgaard-Oeschger Events on Isotope Plots of Siberian Ice Wedges


Hydrogen and oxygen isotope records with a resolution of 100-200 years were obtained from ice-wedge ice at four locations in Siberia, Micro-organic inclusions and pollen concentrates from ice wedges allowed precise AMS radiocarbon dating of the isotope records and comparison with G1SP2 and GRIP ice cores. Separate Dansgaard-Oeschger events are distinguished within the ice-wedge ice and correlated with the Greenland ice cores.

Direct AMS radiocarbon dates of organic micro inclusions from Siberian ice wedges.The AMS radiocarbon dating was carried out at Groningen University (Head Prof. J. van der Plicht, lab code GRA) and Seoul National University (Head Prof. J.-Ch.Kim, lab code SNU).Data was submitted and proofread by Yurij K Vasil'chuk and Lyubov Bludushkina at the faculty of Geography, department of Geochemistry of Landscapes and Geography of Soils, Lomonosov Moscow State University.
