DENSITY 



Because of the close relationship between the isopleths 

 of temperature and salinity, the isolines of density p , here 

 expressed as <r t [o- t = 10 3 ( P — 1) ], are very similar to the iso- 

 therms and isohalines. Charts giving the horizontal distri- 

 bution of <r t at the surface, at 25 meters, and at 40 meters 

 are shown in figures 45, 46, and 47. The general parallel 

 character of the isopleths of these physical variables indicates 

 that, in general, the conditions are stationary and that the 

 current will flow parallel to the isolines of temperature, sa- 

 linity, and density.
