A Simple Index of Trophic Status in Estuaries and Coastal Bays Based on Measurements of pH and Dissolved Oxygen
Measurements of pH and dissolved oxygen saturation in summer from 90 Irish estuaries and coastal bays were used to develop a simple index of trophic state. The index is based on the assumption that large fluctuations in both these variables are likely to be a characteristic feature of eutrophication...

| description | Measurements of pH and dissolved oxygen saturation in summer from 90 Irish estuaries and coastal bays were used to develop a simple index of trophic state. The index is based on the assumption that large fluctuations in both these variables are likely to be a characteristic feature of eutrophication. In this paper, we use a simple index to capture the relative variation in both pH and dissolved oxygen saturation in each water body during a period of 3 years. We show that the index is in good agreement with other trophic status schemes and strongly correlated with parameters indicative of trophic state such as chlorophyll a and biochemical oxygen demand. We conclude that the index could be used as a simple screening tool to group individual water bodies into broad categories that reflect their trophic state. |
