Imbalances in Dissolved Elemental Export Fluxes Disclose “Hidden” Critical Zone Compartments

In streams, short‐term element‐specific solute fluxes are often not balanced with long‐term chemical weathering fluxes determined in the residual solids from fractional element loss and denudation rate. The ratio of both estimates—the “Dissolved Export Efficiency” (DEE)—is frequently
