TOTAL INANIMATE MATERIAL: Figure 18 repre- 

 sents the sum of fecal pellets, wood fibers, and miscellan- 

 eous debris over 10 microns in diameter. The distribution 

 of these individual entities is shown in the appendix. The 

 greatest concentrations were present near the bottom in 

 the least turbid zones. In addition, concentrations greater 

 than 200 particles per ml were present throughout the water 

 column, yet no correlations were apparent when turbidity 

 and distribution were compared. Observations by divers 

 show that much of this material is churned from the bottom 

 during periods of strong wave surge.
