Optimizing Arena Ice Performance
Optimizing Arena Ice Performance
2023 to present
We are conducting experiments to understand how water quality and environmental conditions affect the physical properties of arena ice. This research includes controlled tests of ice hardness and friction under varying water treatments, temperature settings, and total dissolved solids (TDS) levels. The work combines experimental results with insights from a North America-wide arena operator survey, and contributes to improved rink practices and sustainability.
The effect of wildfires on dissolved carbon and water chemistry in subarctic streams
The effect of wildfires on dissolved carbon and water chemistry in subarctic streams
Under future climate scenarios the western Canadian sub-arctic is expected to experience a high degree of warming, increasing the incidence of wild fires
In this project I investigate the effect of burnt catchments on stream carbon dioxide and methane emissions and overall water chemistry

Molecular characterization of dissolved organic matter
Molecular characterization of dissolved organic matter
The natural dissolved organic matter pool in freshwaters is extremely complex and requires advanced techniques for characterization of its composition
I apply ultrahigh-resolution electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (ESI-FT-ICR-MS) to help understand the molecular composition of DOM and its potential links to DOM quality and reactivity
Large-scale landscape drivers of dissolved carbon in northern river networks
Large-scale landscape drivers of dissolved carbon in northern river networks
Half of the earth's surface freshwater is at high latitudes but the vastness and remoteness makes sampling difficult
In this project I developed predictors of dissolved carbon in rivers based on the watershed landscape
In particular, use of remotely sensed drivers to for prediction at the biome scale
Stream network modelling and upscaling
Stream network modelling and upscaling
Use of geographic information system to model stream networks at large scales and dissolved carbon throughout the landscape
Provides estimates of emissions and carbon export at regional scales
Regional stream network emissions show emergent properties that could apply to biome or global scales
Flow of nutrients and organic matter between terrestrial and aquatic ecosystems
Flow of nutrients and organic matter between terrestrial and aquatic ecosystems
The terrestrial landscape is an important source of carbon and nutrients to aquatic systems
Reactive interfaces such as the soil-stream interface are especially important for these transfers
I show the composition and importance of dissolved organic matter lost in this interface in sustaining CO2 emission
Whole watershed characterization
Whole watershed characterization
The watershed landscape contributes non-point sources of carbon, nutrient and contaminants at large scales
To fully understand the human impacts on rivers and downstream lakes the entire contributing watershed must be sampled and characterized
I investigated the effects of human impacts on dissolved organic matter quality and found urbanization causes disproportionate changes compared with agriculture
