Sea Water Density at Various Temperatures 



79 



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. It is intended primarily for use with 

 this density publication which gives densities at 59°F. and with Coast and Geodetic Survey Special Publication 

 No. 280 which gives sea water temperatures for the same stations. 



To convert a density at 59°F. to density at another temperature, enter the graph horizontally from the 

 left with the known density and downward from the top 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.
