520 |a"The Lake Erie Central basin hypolimnetic oxygen depletion rates have been reassessed using a new approach. A semi-objective method using oxygen depletion rates and chemical data was used to determine the trend study area, where the high spatial variability that exists in the Central Basin, was reduced by 80 to 90%, thus allowing any time-trend to be identified with more precision"--Exec. summary.
