Silicate minerals typical of those carried in the suspended load of streams release silica to silica-deficient sea water and abstract silica from silicaenriched sea water. Experimental rates of release and uptake permit the conclusion that the suspended solids carried into the oceans by streams are a major control of the concentration of silica in the ocean.
