Ocean acidification threatens to reduce pH and aragonite saturation state (Ω A ) in estuaries, potentially damaging their ecosystems. However, the impact of highly variable river total alkalinity (TA) and dissolved inorganic carbon (DIC) on pH and Ω A in these estuaries is unknown. We assess the sen...
