ANOVA RESULTS FOR PRIMARY PRODUCTIVITY 



MEASUREMENTS ANALYZING THE SUMS OF FRACTIONS 



AND UNFRACTIONATED TOTALS 



Three-Way ANOVA on Sums of Fractions for Stations 

 FRB and KD (all dates) 



Two-Way ANOVA on Unfractionated Totals for Stations 

 FRB and KD (all dates) 



*Significant at a = 0.05. 



Evidence of patchiness was found on several occasions. For 

 example, on Aug. 26 there was a relatively high concentration for the 



> 64-/am fraction at station KWI which was not observed at any of 

 the other stations. Similarly, high values were recorded for the 



> 64-iim fraction on Sept. 20 at all stations except REF. 



On the average, pre- and postcondenser chlorophyll a concentra- 

 tions were comparable. The relative concentrations were 104, 98.5, 

 102, 99, and 101% of those found at FRB for the < 10-, 10- to 64-, 

 and > 64-/im fractions, the unfractionated total, and the sum of the 

 fractions, respectively.
