APPENDIX II 



FREEZING TEMPERATURES AND DENSITIES FOR SEA WATER 



Tables 1 and 2 demonstrate the linear relationship between salinity 

 and density of freezing and between salinity and maximum density, respectively. 



The temperatures of freezing were computed by equation 1. The 

 densities of freezing were determined from the tables in H. 0, Pub. No. 615 

 using salinity and temperature of freezing as the arguments. The maximum 

 densities were obtained by inspecting the same tables for maximum values at 

 the indicated salinity. The temperatures of maximum density are computed by 

 the approximate formula by Sverdrup? 



T (%ax) - 4.00°C. - 0.21$ S. 



It will be noted in Table 2 , that a range of temperatures of maximum density 

 actually satisfies the maximum density value to three decimal places in < r ^. 

 However, the numerical accuracy that has been maintained in Tables 1 and 2 

 is greater than the optimum accuracy in actual practice.
