Assessing the Role of Discourse in Influencing Water Quality Policy in Lake Erie Basin
(University of Waterloo, 2020-01-27)This research examines the usefulness of a discourse approach to better understand freshwater policy and governance, with a specific focus on the involvement of non-state actors in the policy making process. Previous ... -
Benthic-pelagic coupling and spatial dynamics of nutrient availability for benthic nuisance algae in the rocky nearshore zone of eastern Lake Erie
(University of Waterloo, 2019-09-03)Nuisance Cladophora growth in the nearshore during the summer growing season tends to imply nutrient, particularly phosphorus (P), enrichment in the benthos, especially where there is adequate light and hard substrate that ... -
The carbon and nitrogen composition of suspended particulate matter in Lake Erie, selected tributaries, and its outflow
(University of Waterloo, 2005)Since their introduction to Lake Erie, dreissenid mussels may have reengineered the cycling of nutrients in the lake so that the nearshore benthic community intercepts, retains, and recycles greater quantities of nutrients. ... -
Checkered Landscapes: Quantifying Dominant Control on Nitrogen Legacies and Time Lags along the River Continuum
(University of Waterloo, 2020-08-20)In agricultural watersheds across the world, decades of commercial fertilizer application and intensive livestock production have led to elevated stream nutrient levels and problems of eutrophication in both inland and ... -
The distribution of Dreissena and other benthic invertebrates in Lake Erie, 2002.
(University of Waterloo, 2012-02-22)A lake-wide benthic survey of Lake Erie during summer 2002 indicated that Dreissena bugensis is the dominant dreissenid in Lake Erie, especially in the east basin where this species was found at every station but no Dreissena ... -
Drivers and Implications for Water Governance: A case study of the western Lake Erie basin
(University of Waterloo, 2022-08-02)The purpose of this study was to better understand drivers of water problems and their implications for water governance scholarship and practice. Drivers here are identified as social and environmental forces affecting a ... -
Ecological Modelling of Lake Erie: Sensitivity Analysis and Simulation of Nutrient, Phytoplankton and Zooplankton Dynamics
(University of Waterloo, 2011-05-02)Lake Erie has undergone a substantial amount of ecosystem changes over the past century; including cultural eutrophication and several invasions by industrious exotic species. Simple mass balance models for phosphorus have ... -
EVOLUTION OF LAKE ERIE BASED ON THE POSTGLACIAL SEDIMENTARY RECORD BELOW THE LONG POINT, POINT PELEE, AND POINTE-AUX-PINS FORELANDS
(University of Waterloo, 2016-09-27)The postglacial geological history of Lake Erie was interpreted primarily on the basis of borehole sedimentary sequences below the major accretionary forelands: Long Point, Point Pelee, and Pointe-aux-Pins. These data ... -
Great Lakes Regional Water Conflict Analyses
(University of Waterloo, 2021-03-25)This research proposes a holistic framework to help understand and mitigate the interrelated and successive conflicts that occur over water resources in the Great Lakes and the rivers flowing into them. Local Canadian ... -
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 ... -
Investigating the use of variable fluorescence methods to detect phytoplankton nutrient deficiency
(University of Waterloo, 2013-04-29)Variable fluorescence of chlorophyll a (Fv/Fm), measured by pulse amplitude modulated (PAM) fluorometers, is an attractive target for phytoplankton-related water quality management. Lowered Fv/Fm is believed to reflect ... -
Modeling the growth dynamics of <em>Cladophora</em> in eastern Lake Erie
(University of Waterloo, 2005)<em>Cladophora glomerata</em> is a filamentous green alga that currently forms extensive blooms in nearshore areas of Lake Ontario, eastern Lake Erie, Lake Michigan, and isolated locations in Lake Huron. The biomass, ... -
Phytoplankton dynamics in nearshore and offshore regions of the Great Lakes Erie, Malawi, Tanganyika, and Victoria
(University of Waterloo, 2008-02-22)My doctoral thesis challenges the traditional paradigm of phosphorus (P) limitation of phytoplankton communities in freshwaters by suggesting colimitation of P, nitrogen (N), and iron (Fe) in Great Lakes. Oceanographers ... -
Retrieval of Lake Erie Water Quality Parameters from Satellite Remote Sensing and Impact on Simulations with a 1-D Lake Model
(University of Waterloo, 2016-02-26)Lake Erie is a freshwater lake, and the most southern of the Laurentian Great Lakes in North America. It is the smallest by volume, the fourth largest in surface area (25,700 km2), and the shallowest of the Laurentian Great ... -
Simulating Wintertime Lake Dynamics Using the MITgcm Ice Model
(University of Waterloo, 2020-09-23)Lake Erie is an important source of drinking water, a location for recreational activities and a haven for unique ecosystems (e.g. Point Pelee). Recent research has suggested that some wintertime processes are significantly ... -
Three Dimensional Hydrodynamic Modelling of Lake Erie: Kelvin Wave Propagation and Potential Effects of Climate Change on Thermal Structure and Dissolved Oxygen
(University of Waterloo, 2013-07-25)This thesis investigates physical processes in Lake Erie, a large, shallow mid-latitude lake, from two perspectives: climate change impacts on the thermal structure and dissolved oxygen concentration and small-scale eddy ...
