Long-Term Changes in Concentration and Yield of Riverine Dissolved Silicon From the Poles to the Tropics ...
Abstract Riverine exports of silicon (Si) influence global carbon cycling through the growth of marine diatoms, which account for ∼25% of global primary production. Climate change will likely alter river Si exports in biome-specific ways due to interacting shifts in chemical weathering rates, hydrol...
