CHEMICAL STUDIES 



Chemical research at the tower is concerned with several 

 phases of the oceanographic program. Salinity, in conjunction 

 with temperature, is determined for use in computing sound 

 velocity and water density. Oxygen content and foaming properties 

 are studied in connection with sound propagation and attenuation. 

 Plant nutrients are investigated for their influence on phy to plankton 

 production, which largely controls underwater visibility. Radio- 

 activity of marine organisms is studied for biological absorption 

 research.
