  "abstract": ". Here we synthesize observations from natural volcanic watersheds to evaluate alkalinity export along the complete reactive pathways from soil to river. Data from basaltic catchments demonstrate attenuation of alkalinity fluxes, leading to reductions in exported alkalinity. This attenuation is probably the result of precipitation of secondary clay and carbonate minerals along subsurface flow paths and during river transport. Although natural weathering systems differ from engineered EW deployments, these observations provide an empirical baseline on watershed-scale alkalinity export. Our results indicate that critical zone processes influence the efficiency with which weathering-derived alkalinity is exported, implying the need to incorporate watershed processes into future assessments of EW CDR.",
