Fluxes of largest volcanic peaks in the EDC sulfate record

An existing ice core sulfate dataset was processed to identify the largest volcanic eruption peaks of the last 203 kyr. The dataset used consisted of high resolution sulfate data (previously archived at https://www.ncdc.noaa.gov/paleo-search/study/31332), analysed by fast ion chromatography, from th...

Description
Summary:An existing ice core sulfate dataset was processed to identify the largest volcanic eruption peaks of the last 203 kyr. The dataset used consisted of high resolution sulfate data (previously archived at https://www.ncdc.noaa.gov/paleo-search/study/31332), analysed by fast ion chromatography, from the EPICA Dome C ice core. To process the data, a background was removed, and fluxes of sulfate deposited were calculated for every peak above background, using a consistent method that corrects for ice accumulation rate and thinning. A threshold flux of 20 mg m⁻² yr⁻¹ has been used to ensure that only peaks of definite volcanic origin are listed. This dataset lists the depths, ages (AICC2012 age model) and fluxes of each peak with a flux > 20 mg m⁻² yr⁻¹.
