Abstract
A simple method is presented for predicting oxygen profiles under ice cover in selected Ontario lakes. The oxygen loss rate within individual lake strata over winter can be predicted from the oxygen concentration in each stratum about 5 – 15 d after freeze-up (at the time of maximum volume-weighted oxygen concentration for the lake). Shield lakes and limestone-transition lakes are described by two distinct relationships; the rate of oxygen loss per unit oxygen concentration is greater in the limestone-transition lakes.Key words: lake-oxygen concentration, limestone lakes, lake respiration, oxygen profile, lake depth, oxygenation/oxidation processes, ice cover, Shield lakesThis publication has 3 references indexed in Scilit:
