Abstract
Two-station diel dissolved oxygen measurements collected during 1976 and 1977 at the Monticello Ecological Research Station (Monticello, MN) have been analyzed by a graphical-analytical method and by a computer model, Dissolved Oxygen Routing Model (DORM), to determine daily community respiration and photosynthesis. A third set of values was generated by using the DORM model to simulate the graphical method. The complete DORM included surface oxygen exchange, longitudinal dispersion, a higher order curve extrapolation between upstream dissolved oxygen measurements and the dependence of respiratory rate on water temperature and dissolved oxygen measurements and the dependence of respiratory rate on water temperature and dissolved oxygen concentration, but neither the graphical nor the simulated graphical models included these factors.

A third set of values was generated by using the DORM model to simulate the graphical method. The complete DORM included surface oxygen exchange, longitudinal dispersion, a higher order curve extrapolation between upstream dissolved oxygen measurements and the dependence of respiratory rates on water temperature and dissolved oxygen measurements and the dependence of respiratory rate on water temperature and dissolved oxygen concentration, but neither the graphical nor the simulated graphical models included these factors. The complete DORM gave consistently higher rates of respiration and photosynthesis than either the graphical-analytical method or the computer simulation.
