Seasonality in phosphorus release rates from the sediments of a ...

Phosphorus trapped in the oxic microlayer (sorption) is freed when the microlayer is chemically reduced at the onset of anoxia and high P release rates are ...

Abstract: Phosphorus release rates were measured on intact sediment cores collected from the major depositional basin of Onondaga Lake, a dimictic, ...

Seasonal sediment phosphorus release across sediment-water ...

Seasonal sediment internal phosphorus (P) release is known to affect annual algal blooms in eutrophic lakes. In this study, a year-long ...

Seasonal Release Potential of Sediments in Reservoirs and Its ...

Previous studies have indicated that phosphorus and nitrogen released from sediments are the main determinants of eutrophication following ...

Phosphorus release from the peaty sediments of the Loosdrecht ...

Seasonal patterns in phosphorus release from sediments of the Loosdrecht Lakes were studied ... phosphorus release rates cannot be excluded.

Importance of temperature, nitrate, and pH for phosphate release ...

Gross release rates were 15, 21, 33, and 100 mg P m−2 d−1(average summer values). In three of the lakes, water temperature alone explained ∼70% of the seasonal ...

Seasonal hypoxia enhances sediment iron-bound phosphorus ...

More organic-P was observed in summer compared to spring. A significant increase in labile P occurred at the depth of 0-4 cm and 0-1 cm in ...

Seasonal and inter-annual patterns of sediment-water nutrient and ...

However, when production rates are high, as in August of 1994, even very high rates of nitrogen and phosphorus release by the sediments ...

Seasonal changes of sediment characteristics, phosphorus release ...

... A few factors are known to regulate the release rates of phosphorus and nitrogen. Phosphorus and nitrogen release rates increased with the increase in water ...

Accelerated sediment phosphorus release in Lake Erie's central ...

We found no evidence that re- aerated anoxic P flux differed between seasons across all stations, however there was strong evidence that summer CB4 rates were ...

Accelerated sediment phosphorus release in Lake Erie's central ...

Table 3 shows that oxic P flux was lower than anoxic P rates across all seasons, stations, and temperatures. Rates within each phase of the experiment were ...

Accelerated sediment phosphorus release in Lake Erie's central ...

We used 56 controlled sediment core incubation experiments to quantify rates and onset of P release in Lake Erie's central basin as a function of depositional ...

Some sediments did not release phosphorus under any conditions. The second category showed a high phosphorus release rate when acetate was added, in order ...

Role of sediment and internal loading of phosphorus in shallow lakes

Then, high phosphorus release rates are observed. In this way, the oxidized microlayer may serve to regulate seasonal- ity in rates of sediment phosphorus ...

Iron filings application to reduce lake sediment phosphorus release

Under oxic conditions, PO4-P release did not occur from the sediments, and low water column PO4-P concentrations were maintained in the iron- ...
