| Brief text description |
Relation beween the log of Chlorophyll a and the log of the concentration for SIN and SRP. |
| Long text description |
Relation between the max monthly benthic algal biomass in mg/m2 chlorophyll a and SIN and SRP in (mg.L-1):
log10 (Chl a) = 0.688 log10 SIN + 0.711 (rē=0.325, p=0.001)
log10 (Chl a) = 0.797 log10 SRP + 1.400 (rē=0.295, p=0.002)
Nutrient range:
SIN=6.2-232 mg.L-1
SRP=1.3-31.6 mg.L-1
