| Brief text description | Regression equations betweem chlorophyll a per square metre and inorganic nutrient concentrations |
| Long text description | Increase in nutrients (P and N) is causing an increase in phytobenthic biomass. This relationship can be expressed through regression equations between log(chloro a/m2) and log(TP) or log(TN) or log(SIN) or log(SRP) |
