Silicon isotope values (δ30SiDSi) of dissolved silicon (DSi) have been analyzed in the Lena River and its tributaries, one of the largest Arctic watersheds in the world. The geographical and temporal variations of δ30SiDSirange from +0.39 to +1.86‰ with DSi concentrations from 34 to 121 μM. No obvio...
