متن کاملHypolinimetic oxygen deficits: their prediction and interpretation.
Rates of hypolimnetic oxygen depletion can be predictedfrom a knowledge of a lake's phosphorus retention, the average hypolimnetic temperature, and the mean thickness of the hypolimnion. Areal oxygen deficits cannot be used to index lake trophic status because areal calculations do not eliminate the influence of hypo-limnetic morphometry.
متن کاملEstimates of hypolimnetic oxygen deficits in ponds
Shallow tropical integrated culture ponds in the Pearl River Delta. China, have been found to stratify almost daily, with high organic loadings and dense algal growth. The dissolved oxygen (DO) concentration is super-saturated in the epilimnion and is under 2 mg/l in the hypolimnion (>lm). The compensation depth corresponds to twice the Secchi disk depth ranging from 50 to 80cm. As a result, li...

15 صفحه اولPhosphorus Retention in Sediments
Phosphate is usually the most important growth limiting nutrient in aquatic environments-The availability of P is the result of external load and retention in the sediments. This latter is the result of a number of transport, microbial and chemical processes. 'The role of P in the productivity in systems and in the eutrophication process has initiated a large number of studies to the behaviour ...
