A 110,000-Yr Record of Explosive Volcanism from the GISP2 (Greenland) Ice Core
Abstract The time series of volcanically produced sulfate from the GISP2 ice core is used to develop a continuous record of explosive volcanism over the past 110,000 yr. We identified ∼850 volcanic signals (700 of these from 110,000 to 9000 yr ago) with sulfate concentrations greater than that assoc...
