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...
