and other dinoflagellates , each of which correlated with 

 the thermocline, strengthened the positive relationship 

 between total microorganisms and temperature. 



TOTAL INANIMATE MATERIAL: Inanimate mate- 

 rial (fig. 18) was generally distributed throughout the water 

 column and showed no obvious relation to thermal structure. 

 Points of equal concentration are found within, above, and 

 below the thermocline. Furthermore, the area of highest 

 particle count (0100 to 0700 7 July) was found near the 

 bottom, well below the thermocline, and represented 

 material that had settled out of the water column or had 

 been stirred up from the bottom by water m.ovement. 



TOTAL MICROCONSTITUENTS: With the exception 

 of bottom concentrations from 1800 6 July to 0500 7 July, 

 the distribution of all microconstituents (fig. 19) closely 

 paralleled the thermal gradient and demonstrated the same 

 general distributional pattern of the microorganisms that 

 comprised the bulk of the particulate material in the water.
