tj, 10~5cm.3/g. - thermosteric anomaly, the 

 anomaly of specific volume 

 attained if water were 

 changed isothermally to a 

 standard pressure of 1 at- 

 mosphere, relative to a 

 standard sample of 35 / 

 salinity, 0° C. at the same 

 pressure. Tabular values 

 multiplied by 10"^ will give 

 the anomaly in cm.^/g. 



4D, dyn. m. - geopotential anomaly in 



dynamic meters of the 

 water layer between sur- 

 face and designated pres- 

 sure. (Depth in meters is 

 assumed numerically equal 

 to pressure indecibars.)
