Biogeochemical cycling of nutrient silicon in a human-impacted large lake nearshore environment (Hamilton Harbour Area of Concern, Lake Ontario, Canada)
(University of Waterloo, 2017-12-14)The biogeochemical cycling of nutrient silicon (Si) through rivers, wetlands, lakes, and artificial reservoirs regulates the magnitude and bioavailability of Si delivered downstream and to the ocean (Frings et al. 2014; ... -
Influence of a dammed reservoir on nutrient (N, P, Si) loads and ratios of the Thames River, Ontario
(University of Waterloo, 2021-01-20)The increasing frequency and severity of harmful algal blooms (HABs) in Lake Erie have been troubling developments in the past few decades. Excess loads of phosphorus (P) from the watershed are considered to be a primary ... -
Interactions of Phosphate and Silicate with Iron oxides in Freshwater Environments
(University of Waterloo, 2019-04-29)Internal phosphorus loads, from bottom sediments to surface waters, are often comparable in magnitude to external phosphorus loads, particularly in water bodies with a history of high external phosphorus inputs from point ... -
Mechanisms controlling the recycling of nutrient silicon in freshwater sediments: An experimental study of the interactions between silicon, iron and phosphorus
(University of Waterloo, 2020-12-23)Dissolved silicon (DSi) is an essential nutrient for numerous terrestrial and aquatic organisms. In freshwater systems, including streams, rivers and lakes, an important class of siliceous algae are diatoms. Human activities, ...
