Charles Charrier-Tremblay MS candidate co-supervised by Jean-François Lapierre (hyperlien JF) [email protected] B.Sc. Biology
Nutrient transformations in streams and rivers
Charles’s project, which stems from a partnership between Université de Montréal and the municipality of St-Hippolyte, focuses on the retention and transformation of nutrients by the hyporheic zone in this region of the Laurentians. The hyporheic zone is a dynamic ecotone that links groundwater to surface water and is principally formed of non-saturated (in water or oxygen) sediments, which offers it a great potential for retention, transformation and remineralization of chemical elements within these freshwater ecosystems. Therefore, through calculations of mass balance, geographic information systems and chemical analyses, Charles will measure water exchanges and quantify the metabolic activity of the hyporheic zone of rivers and streams to compare the variability and the contribution of these biogeochemical processes to the chemical equilibrium of the different water masses.
Career path and other interests
Charles started his undergraduate studies at Sherbrooke University in ecology, where he acquired practical skills thanks to the micro-program in applied ecology. Because aquatic systems have fascinated Charles from a young age, he finished his undergraduate degree in the department of biological sciences, at Université de Montréal and decide to join my team to pursue his love of limnology. In his free time and when the weather permits it, he loves to scuba dive in Quebec lakes to, as he puts it, discover their mysteries and observe the life they conceal. Otherwise Charles relaxes by playing one of the several musical instruments he masters: guitar, mandolin, and harmonica.
