TOTAL MICROORGANISMS: The time -depth 

 distribution of all microorganisms (fig. 28) enumerated 

 in this study parallels the distribution of Gymnodinium flavum, 

 Ceralium fusus, and C. furca. With minor exceptions the cells 

 are distributed below the 70 °F isotherm. The points of 

 highest population density (2000 20 July at 38 feet and 

 0500 21 July at 18 feet) were found to correlate with verti- 

 cal oscillations in thermal structure. 



TOTAL INANIMATE MATERIAL: The distribution 

 of particulate material other than organisms (fig. 29) is 

 general throughout the water column. Centers of highest 

 concentration were found at the surface, in mid-water, and 

 near the bottom. No general correlative pattern with tem- 

 perature was apparent. 



TOTAL MICROCONSTITUENTS: As expected, the 

 distribution of total microconstituents (fig. 30) was similar 

 to the distributions of the predominant individual micro - 

 entities. The major areas of population density fell below 

 the 70 °F isotherm and were centered on the vertical 

 oscillations of the thermal gradient cited previously.
