Improper attention to thawing can result in severe negative and variable bias in seawater determination for silicate when samples have been stored by freezing. To control bias requires an adjustment of the length of time between thawing the sample and analyzing it, depending on salinity, silicate concentration, and length of time frozen. Figures are given which allow the optimum selection of thaw time.
