Estimation of Primary Productivity in Aquatic Systems Using Free Oxygen Measurements (original) (raw)
1980, Journal of the American Water Resources Association
A one-dimensional model for heat and oxygen transport is frequently used for the estimation of primary productivity. Such a model employs free oxygen and temperature measurements at discrete time and depth intervals. In this method the eddy diffusion coefficients of heat and oxygen are assumed to be interchangeable. This method was applied to hourly data for 24-hour periods in a small temperature stratified lake. Primary productivity was simultaneously measured with the light and dark bottle method. The application of the free oxygen method resulted in unrealistic estimates of productivity. Some consideration is given to the origin of the failure in the application of this method.
