2600 years of stratospheric volcanism reconstruction through sulfate isotopes for Antarctic ice cores ...
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. Five closely-located ice cores from Dome C, Antarctica, are used to reconstruct a record that differs subtly from recent reconstructions calibrated using synchronous volcanic sulfate deposition in Greenland and Antarctica to identify eruptions with global-scale sulfate distribution. 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. The comparison also reveals several high latitude stratospheric events that are not bipolar.
