proves higher than that of each of the waters prior to mixing. It is easy to see that such a highly 

 interesting density increase is possible only if the mixing curve intersects the isostere of the 

 denser mixing water and only if the mixing proportions lie on the "chord" of this isostere. 



TABLE 2. INCREASE IN DENSITY WHEN EQUAL WATER MASSES OF 

 UNIFORM DENSITY ARE MIXED 



TABLE 3. TEMPERATURE, SALINITY, NATURAL DENSITY AND 

 DENSITY INCREASE AFTER THE WATERS HAVE 

 BEEN MIXED IN DIFFERENT PROPORTIONS 



Table 3 shows the results of mixing the two waters in different proportions: 1) t -^ =0°, 

 5]^ = 9.0 o/oo and 2) tg = 10°, 5 g = 10.0 o/oo. The last column of the table gives the density in- 

 crease relative to the densities computed from the mixing formula. As can be seen from the table, 

 when the masses of denser water are greater than those of less dense water, the density of the mix- 

 ture is greater than that of the denser water. With other proportions, although density increase 

 occurs, the density of the mixture is intermediate between the densities of the mixing waters.
