Nitrification, a significant cause of oxygen depletion under winter ice / by Roger Knowles and David R.S. Lean.: En13-5/86-138E-PDF

"Changes in concentrations of oxygen and the various nitrogenous forms in Lake St. George from 1976 to 1964 showed that nitrification (conversion of ammonium to nitrite and nitrate) caused an average of 71% of the winter oxygen depletion.This represents the most significant biological processes in the winter months. In fact, it is 30 X greater than plant photosynthesis. Bottle bioassays for nitrification were evaluated to determine how well they would predict rates measured in the lake itself"--Management perspective.
