| Abstract |
The results of a series of simulations of the response of the open lake region of Lake Ontario to various levels of nutrient input are described. The simulations use a simplified dynamic model of phytoplankton - nutrient interactions in a vertically segmented structure. The analysis of long term simulations (10-20 years) indicates that the overall loss rates of nutrient are of particular importance. Under reasonable set of model parameters, the simulations indicate that the present observed open lake phytoplankton biomass of Lake Ontario does not appear to be in equilibrium with the present input nutrient load. Therefore, if the present load is continued, it is estimated that spring peak phytoplankton chlorophyll in the epilimnion will continue to increase to a new level about 45% higher than present levels. |
