My research focuses on how climate change and degrading permafrost will change nutrient loading in High Arctic watersheds. As part of my master’s thesis, I will be taking on two distinct but related projects. The first builds on previous work done in the Niaqunguk Watershed outside of Iqaluit where small-scale differences in geomorphology may have major impacts on water quality. My second project will be conducted in the West River Watershed on Melville Island Nunavut. A nitrogen budget of the watershed and some of its subsidiaries will be done to examine how a deepening active layer and changing precipitation regimes in the High Arctic are changing the export of nitrogen, an important nutrient for aquatic ecosystems.

My research examines the carbon cycle in High Arctic environments. My thesis project takes place at the Cape Bounty Arctic Watershed Observatory on Melville Island, Nunavut, where I focus on the carbon balance of wet sedge watersheds. I’m interested in measuring the total fluxes of carbon from these watersheds, both directly to the atmosphere and through streams. My fieldwork combines measurements of terrestrial greenhouse gas fluxes throughout the watershed and measurements of a variety of dissolved and particulate carbon species in streams. Ultimately, I want to understand in what forms carbon is being lost and how much is eventually released to the atmosphere as greenhouse gases. As they warm, High Arctic environments are rapidly changing – understanding the extent to which the carbon balance will be impacted is important to our predictions of future change.
