A 6-m.y.-long composite marine record of explosive silicic volcanism from five Ocean Drilling Program sites in the subpolar North Atlantic was compared with several marine records of global and local paleoclimate proxies (benthic δ18O and ice-rafted debris records). Coarsening and high frequency of...
