Lake Erie oxygen revisited / by Murray N. Charlton. : En13-5/85-37E-PDF
"The problem of predicting the future hypolimnion oxygen regime in Lake Erie from past records is re-assessed. Instead of comparing oxygen depletion rates, the data were manipulated to reveal comparable concentrations at the end of August each year. By removing confusion caused by variable concentrations at the beginning of stratification, the expected change of 0-2 mg/L from the 1950s to present was revealed. The oxygen regime of the east basin has changed little if at all; the year to year variability being as large as possible trends in concentration. A water sampling device used in the earliest samplings was found to produce incorrect samples under certain conditions thereby lessening confidence in the early data. The trajectory of oxygen concentration after stratification is independent of epilimnion productivity. It is proposed that oxygen depletion depends on average trophic conditions preceeding each stratified season"--Abstract.
