Multiple lines of evidence reveal rapid, seasonal watershed responses to enhanced weathering
A whole-watershed experiment revealed rapid streamwater alkalinity increases within weeks of basalt application, with strong seasonal cycling and the export of ~10% of theoretical carbon removal as alkalinity over 2 years, underscoring that temperature and hydrologic variability critically govern enhanced weathering effectiveness and monitoring.
