Impact of Winter Soil Processes on Nutrient Leaching in Cold Region Agroecosystems
(University of Waterloo, 2021-02-25)High-latitude cold regions are warming more than twice as fast as the rest of the planet, with the greatest warming occurring during the winter. Warmer winters are associated with shorter periods of snow cover, resulting ... -
Natural source zone depletion of petroleum hydrocarbons under variable temperature and moisture conditions
(University of Waterloo, 2023-02-15)In subsurface environments contaminated by petroleum hydrocarbons (PHCs), the steep geochemical and redox gradients near the water table, the oxygen availability, moisture content, salinity, pH, nutrient concentrations and ... -
Soil Oxygen Monitoring with Fibre Optode Sensors: Experimental Evaluation in Soil Columns under Fluctuating Water Table and Freeze Thaw Conditions
(University of Waterloo, 2017-01-23)The biogeochemical functioning of natural and engineered environments is closely linked to spatial and temporal variations in molecular oxygen (O2) concentrations. A luminescence-based, Multi-Fibre Optode (MuFO) microsensor ...
