File structure: Source data Contains source data to main text and extended data figures. Data sources are identified within and listed below. Computer codes Geochemical inversion – “Data for geochemical inversion.xlsx”: contains Gulf of Alaska sediment and volcanic/terrigenous endmember geochemical data used for data inversion. “geochemical inversion.r”: R script used to perform geochemical inversion. “GOA inversion fraction.csv”: Result of the geochemical inversion, including the volcanic and terrigenous fractions in each Gulf of Alaska sediment sample. “GOA inversion residual.csv”: Result of the geochemical inversion, including the residuals of each element. cluster volcanic geochemical data – “Database of volcanic geochemistry.xlsx”: compiled database of the geochemistry of volcanic endmember samples. “cluster.r”: R script used to perform cluster analysis on the volcanic samples. “Clustered volcanic data.csv”: the results of cluster analysis. “Dendroplot.r”: R script used to plot the dendrogram for the cluster analysis. “dendro 15 complete euclidean.pdf”: The dendrogram. “Volcanic endmembers.csv”: final geochemical volcanic endmembers based on the cluster analysis. Global volcanic eruption compilation – “eruption.database.intcal20.xlsx”: This file includes the eruption database compiled by this study, as well as the previous compilation of Huybers and Langmuir 2009 EPSL (referred to as HL09). “eruption.ratio.R” and “volc.freq.R”: These are R scripts that compute the eruption frequency of glaciated and unglaciated volcanoes using the eruption database. “eruption.ratio.R”calls the function inside “volc.freq.R”. “Volcanic eruption summary.xlsx”: This file contains the outputs of the R scripts. PISM sensitivity experiment – “ciscyc.5km.epica.ts.10a.nc” and other netcdf files: The output of PISM sensitivity experiments, from Seguinot. (2020).
