A Simple Index of Trophic Status in Estuaries and Coastal Bays Based on Measurements of pH and Dissolved Oxygen

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