Abstract
SEAWATER density, a property of fundamental importance for oceanographers, is usually calculated from salinity (determined by chlorinity titration or measurement of electrical conductivity) using Knudsen's hydrographical tables1. These tables of relationships between salinity, temperature and density are based on the results of only twenty-four seawater analyses2. Recent investigations, especially by Cox, MacCartney and Culkin3, have shown good agreement with Knudsen's tables in the salinity range Sā°= 15ā40. For water of low salinity such as the Baltic Sea, however, there are greater discrepancies caused chiefly by variation of ionic relationships. No detailed investigations have been made so far, because of the difficulty of making very accurate density measurements.
