Abstract : Three computer programs for calculating a continuous function (a Fourier series) describing net community productivity in aquatic environments using measurements of dissolved oxygen concentration, temperature, and salinity with a solution to the oxygen mass balance equation were prepared. These respectively pertain to calculation of (a) temporal variation of net productivity in flowing waters (rivers), (b) depth-averaged net productivity for a standing water body, and (c) the depth distribution of net productivity in standing waters. These methods are particularly well suited to use with continuous automatic data recording. Because continuous monitoring of community productivity and respiration provides a direct measure of the biological effects of water quality change, the methods can be useful in assessing effects of dredging and disposal on aquatic communities.
