Description

Algorithms for the conversion of electrical conductivity to salinity (and vice-versa) for seawater and sodium chloride solutions were developed. Algorithms developed for seawater were based on laboratory measurements of synthetic seawater were based on laboratory measurements of synthetic seawater solutions and are valid for the salinity range from 0 to about 212 ppt at temperatures of 15, 20 and 25°C. Algorithms developed for NaCl solutions were based on literature data and are valid for the salinity range from 0 to about 250 ppt at temperatures of 20 and 25°C. Previous work by others for the conversion of salinity to the freezing temperature for seawater solutions is discussed. From this work, expressions for the conversion of the freezing temperature to salinity were derived and are given for the salinity range from 0 to about 230 ppt. Algorithms for the conversion of salinity to the freezing temperature (and vice-versa) for sodium chloride solutions were developed, based on literature data, for the salinity range from 0 to about 230 ppt.
