Sediment Phosphorus Cycling In A Managed System Irondequoit Bay, N.Y., Daniel J. White Dec 2006

Sediment Phosphorus Cycling In A Managed System Irondequoit Bay, N.Y., Daniel J. White

Biology Master’s Theses

The current status of internal phosphorus loading was evaluated in Irondequoit Bay, NY, an embayment of Lake Ontario. Sediment core incubation experiments and phosphorus water column profiles were used to quantify the release rate of phosphorus from the deepwater sediments of Irondequoit Bay during summer periods of low hypolimnetic oxygen. The top 25 cm of sediment cores collected monthly from May 2004 through September 2004 were analyzed for total phosphorus, total manganese, total iron, and total aluminum. Phosphorus fractionation of the sediment cores was determined through sequential extraction. Phosphorus water column data collected during the summer of 2003 and 2004 ...


A Reexamination Of Stratification Processes In Ides Cove, N.Y. With Reference To Sediment Geochemistry, George Joseph Pesacreta Jun 1981

A Reexamination Of Stratification Processes In Ides Cove, N.Y. With Reference To Sediment Geochemistry, George Joseph Pesacreta

Biology Master’s Theses

Ides Cove is a small, relatively deep, isolated body of water off Irondequoit Bay of Lake Ontario, Irondequoit, N.Y. In 1970-71, the cove was meromictic with meromixis being attributed to the heavy application of deicing salts in the cove's watershed. Application of deicing salts to roads in the Town of Irondequoit has steadily declined from 31,230 metric tons in 1970-71 to 3,981 tons in 1979-80. Salt concentrations in surface waters of the cove have decreased since 1970. Complete mixing of the water column was observed during the winter of 1979-80 suggesting the town's "sensible salt ...
