Experiments were conducted in both standing and moving water communities to evaluate the use of a plastic dome for correcting diurnal oxygen curves for diffusion of oxygen between the air‐water interface. Diurnal oxygen curves in systems where diffusion of oxygen through the air‐water boundary occurs were corrected by means of data from the plastic dome experiments to obtain curves in agreement with those from closed systems with no diffusion. The upstream‐downstream diurnal oxygen curve method for running water ecosystems was modified to yield diurnal rate‐of‐change curves like those in still water.
