Relation Between Depth and the Product of Absolute Temperature and 

 Salinity

ed on a single series of observations 

 made in section 40^ on August 

 11, 1911 



Based on the mean annual temperatur 



and salinitv as shown by plates

owing to evaporation at the surface it increases progressively toward 

 the surface. Thus such a high concentration is maintained at the 

 surface that there is continual diffusion of salts toward the bottom
