Evidence for Participation of Anammox in Nitrogen Attenuation Observed in Groundwater Impacted by a Manure Lagoon
(University of Waterloo, 2012-01-23)Decades of agricultural use of fertilizer and manure has resulted in nitrogen being the most common groundwater contaminant. Of the known processes for nitrogen attenuation, both denitrification and anammox produce a ... -
Impacts of Dredging and Brush Cutting of Paired Agricultural Drainage Ditches on GHG Emissions and Nutrient Filtration Capacity
(University of Waterloo, 2023-01-04)Agriculture provides many beneficial and essential ecosystem services. Along with these beneficial services, the conversion of natural ecosystems into heavily modified agricultural ecosystems is also a source of ... -
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 ... -
The Nitrogen Legacy: Understanding Time Lags in Catchment Response as a Function of Hydrologic and Biogeochemical Controls
(University of Waterloo, 2016-09-23)Global population has seen a more than threefold increase over the last 100 years, accompanied by rapid changes in land use and a dramatic intensification of agriculture. Such changes have been driven by a great acceleration ... -
Phosphorus and Nitrogen Cycling in the Mediterranean Sea: Circulation, biogeochemistry and anthropogenic forcing
(University of Waterloo, 2017-04-28)The Mediterranean Sea (MS) is an oligotrophic marine basin despite being semi-enclosed with unusually low inorganic phosphorus (P) and nitrogen (N) concentrations, and high nitrate (NO₃):phosphate (PO₄) ratios comparative ...
