2600 years of stratospheric volcanism reconstruction through sulfate isotopes for Antarctic ice DomeC ...
We present a 2600 year chronology of stratospheric volcanic events using isotopic signatures (Δ33S and in some cases Δ17O) of ice core sulfate. Five closely-located ice cores from Dome C, Antarctica, are used to reconstruct a record that differs subtly from recent reconstructions calibrated using sy...

We present a 2600 year chronology of stratospheric volcanic events using isotopic signatures (Δ33S and in some cases Δ17O) of ice core sulfate.

Comparing the Dome C stratospheric reconstruction shows good agreement with the recent parts of these bipolar reconstructions, but diverges deeper in the record revealing tropospheric signals for some previously assigned bipolar events.
