ABSTRACT 



Tables are presented for the rapid computation on a 

 machine calculator of density (sigma-t) and electrical 

 conductivity of sea water from observed temperature 

 and salinity values. Tables for sigma-t cover the salinity 

 range from lO.OOVoo to 40.00Voo, those for electrical 

 conductivity from 0°/oo to 40°/oo. Computed values for 

 sigma-t may have an error of 2 units in the second 

 decimal place. Computed values for electrical conduc- 

 tivity may have an error of 2 or 3 units in the fourth 

 decimal place.
