Our lab studies how lakes respond to environmental change, focusing on redox processes, sediment–water interactions, and oxygen dynamics in boreal and Arctic ecosystems.
Our work is deeply field-based, bringing us onto northern landscapes to understand aquatic systems where change is happening in real time.
Prof. Raoul Couture
I lead the Aquatic Geochemistry Group in the Department of Chemistry at Université Laval. My research explores how nutrients and trace elements cycle through boreal and Arctic lake systems, combining field observations and modeling to better understand and predict ecosystem responses to environmental change.
Research Program
Our research approaches integrate field campaigns, laboratory geochemical analyses and coupled biogeochemical-physical modeling frameworks.
Approach
We use a multi-disciplinary and multi-scale approach. We collaborate with engineers, biologists, hydrologists and computer scientists to acquire real-time data and environmental samples in the field, conduct laboratory experiments and develop numerical models that capture processes from the molecular to the system scale.
Field work
Our research begins in the field, where we sample lakes, rivers, soils and sediments in temperate and northern catchments. We rely on the network of stations of the Center for Northern Studies. We work with local communities to focus on issues of water quality related to natural environments under climate and land use change.
