 read to 0.01° C. Surface 

 temperatures from 

 bucket samples read to 

 0.1° C.

 ligram-atoms per liter.

The interpolated data are derived 

 entirely from observed data by a three- 

 point interpolation routine utilizing the 

 IBM 650 machine. 



10^6 --Specific volume anomaly 

 at the indicated depth. 



AD --Anomaly of dynamic 



height, in dynamic 

 meters, of the sea sur- 

 face relative to the indi- 

 cated depth in meters. 



* --Extrapolated value. 



Plankton data 



The 1/2 -meter net data are pre- 

 sented as numbers of organisms and 

 as nunnbers of copepods per cubic 

 meter of water filtered, the efficiency 

 of the net assumed to be 100 percent. 



The total number of copepods is pre- 

 sented under COPEPODA in the table 

 of organisms. Analyses of samples 

 were conducted identically to those of 

 1958. 



*- -Indicates organism present but 

 not abundant enough to show in 

 tabulation.
