GISP2 Volcanic Sulfate From 9 to 16 Ka
|Periods of greatest warming coming out of the last ice age are contemporaneous with times of sulfate anomalies in numerous contiguous layers (blue circles containing the number of layers). Red bars show sulfate anomalies in individual layers of ice in the
GISP2 borehole. The purple line shows the
proxy for temperature adjusted for gas age. The
is contemporaneous with the largest sulfate anomaly observed. The
is contemporaneous with the largest number of contiguous layers containing volcanic sulfate.
periods of increased glaciation are contemporaneous with little or no volcanism.
