Abstract
THE diffusion coefficient of dissolved monomeric silica in seawater of 36.1% salinity has been determined at 25° C by the diaphragm cell method. The value of the coefficient D is 1.0±0.05×10−5 cm2 s−1. The value at seafloor temperatures is probably about 0.5×10−5 cm2 s−1 and is consistent with empirical diffusion coefficients of silica in pore water-sediment systems of the order of 0.1 to 0.3×10−5 cm2 s−1, when corrections for porosity are made.
