Sea Water Density at Various Temperatures 



85 



The purpose of this graph is to provide the density of sea water at any temperature apt to be encountered when 

 the density at the standard temperature of 59°F (15°C) is known. To convert a density at 59°F (15°C) to density 

 at another temperature, enter the graph horizontally from the left with the known density and downward from 

 the top or upward from the bottom with the desired temperature; the position of the point of intersection with 

 respect to the curves gives the density at the desired temperature. Interpolate between curves when necessary. 

 For example, by this method, water having a density of 1.0162 at 59° F is found to have a density of 1.0124 at 

 85°F. The densities are referred to the density of fresh water at 4''C (39.2°F) as unity.
