The attenuation of ultraviolet radiation in high dissolved organic carbon waters of wetlands and lakes on the northern Great Plains
We used a scanning spectroradiometer to conduct underwater optical surveys of 44 waterbodies during the ice‐free seasons of three consecutive years in wetlands and lakes in central Saskatchewan,
Next-Generation Sequencing of Microbial Communities in the Athabasca River and Its Tributaries in Relation to Oil Sands Mining Activities
Several taxonomic groups of Bacteria and Archaea showed significant correlations with the concentrations of different contaminants, highlighting their potential as bioindicators.
Relationship between hydrological characteristics and dissolved organic carbon concentration and mass in northern prairie wetlands using a conservative tracer approach
[1] The semiarid prairie pothole region of the North American Great Plains is characterized by millions of small, shallow, closed basin wetlands. These wetlands are hydrologically dynamic, often
Effluent‐dominated streams. Part 2: Presence and possible effects of pharmaceuticals and personal care products in Wascana Creek, Saskatchewan, Canada
The continual exposure to a mixture of pharmaceuticals as well as concentrations of un-ionized ammonia that far exceed Canadian and American water quality guidelines suggests that Wascana Creek should be considered an ecosystem at risk.
Effluent‐dominated streams. Part 1: Presence and effects of excess nitrogen and phosphorus in Wascana Creek, Saskatchewan, Canada
The Wascana Creek study highlights the considerable problems associated with excess nutrients in effluent-dominated ecosystems (EDS) and underlines the need for better controls on NH(4)-N additions from STPs in such EDS, especially in a day and age when freshwater supplies are dwindling and negative effects of climate change are expected.
Saline Inland Waters
Changes in composition and reactivity of allochthonous DOM in a prairie saline lake
Inland saline lakes in semiarid regions of the Canadian prairies contain some of the highest known concentrations of dissolved organic carbon (DOC). This dissolved organic matter (DOM) represents a
Relaxation of phosphorus limitation due to typhoon‐induced mixing in two morphologically distinct basins of Lake Biwa, Japan
We measured changes in hydrodynamics and phosphorus cycling due to a typhoon in two morphologically distinct basins of Lake Biwa, Japan. The typhoon, with wind speeds up to 20 m s−1, led to physical,
