What is the impact of wildfires on aquatic carbon cycling? For my thesis, I use a combination of approaches to answer this vast question at different spatial and temporal scales.
My field site within the Watershed Lab is located in the north of Saguenay. There I monitor water level across two hydrological gradients, from headwater stream, headwater lake, to merging lakes downstream in catchments that were affected by wildfires and ones that weren’t. In the burned catchments, I also monitor dissolved gas concentrations CO₂, CH₄ and O₂ and I apply carbon and water isotope tracers along these two transects.

How headwater stream CO₂ CH₄ emissions respond to hydro-climatic dynamics?
My field site are distributed across a climate gradient including three monitored forested headwater catchments in Québec. I combine multiple sensors to continuously trace dissolved gas concentrations, stream network expansion and contraction, and turbulent gas exchange dynamics.

How do storm events shape lateral carbon export in forested headwater streams?
I lead the SBL headwater catchment where I have instrumented a headwater stream and a preferential groundwater flow slope with sensors. I measure continuously CO₂, CH₄ and O₂ gas concentration, along side C-DOM, conductivity, water table height and temperature.

What can Earth System Models tell us about the future of land carbon export to oceans globally?
I use the CNRM-ESM2-1 model to test the effect of different climate change scenarios on organic carbon export from rivers to oceans worldwide
I produced the tutorial “How to delineate a watershed on R”, which you can find in the resources page.

We are examining the populations of two rare dragonfly species, the Rapids Clubtail (Phanogomphus quadricolor) and the Skillet Clubtail (Gomphurus ventricosus), that were recently identified along a stretch of the Nicolet River in Québec. My project seeks to better understand the habitat characteristics (local and landscape) of both species to better inform conservation strategies.
