respect sire two: the predominance of low 

 values as compared to estuarial or marsh 

 waters, and the high degree of variability. 

 The variability alone gives these determin- 

 ations their significance because they 

 reflect the lack of uniformity in the dis- 

 tribution of the loci of biotic activity 

 in the Gulf of Mexico. This is consistent 

 with the recognized heterogeneous distribu- 

 tion of plankton elements. There is a 

 tendency for the concentrations of the com- 

 pounds found in closely spaced samples to 

 conform to the concept of contagiously 

 distributed populations of plankton as 

 described by Barnes and Marshall (1951).
