On the calcium concentration of the Japanese standard sea water.
Calcium carbonate of sediments in the polyethylene bottles, which had contained 20 liters of sea water for 4 years since it had been collected in the area south of Honshu (Japan mainland), were analyzed. The results of the analysis can be summarized as follows: Calcium concentration of sea water in these bottles was decreased by 0. 1 96 from the initial composition, and this decrease corresponded to 10 to 20 percent of variation in the ratio of calcium to chlorinity of sea water in the ocean. Although this 0. 1% decrease in the ratio of calcium to chlorinity makes the electric conductivity ratio lower for the salinity determination by use of a salinometer, this change is still the same order as the sensitivity of salinometer.
