[1] The sulfur and oxygen isotopic composition of sulfate in polar ice cores provides
information about atmospheric sulfate sources and formation pathways, which have been
impacted regionally by human activity over the past several centuries. We present
decadal scale mean ice core measurements of D17
O, d34
S, D33
S, and D36
