and strontium do penetrate to great oceanic depths (Bowen and Sugihara, 

 1960, Miyake , e_t aj^ 1962), this study becomes still more important. The 

 use of cultures for this type of study of fundamentals is ideal but extra- 

 polation of these results to the open sea environment should not be done 

 without first making a thorough _in situ investigation.
