By | par Clea Phillips La version française suit. After the unexpectedly large snowfall we received in early November, Seonaid and Clea bundled up and headed to the Gault Nature Reserve to winterize our Riparian Ecological Connectivity Observation Network (RECON) sites. This included covering equipment with tarps, as well as removing select sensors that cannot withstand a Quebec winter. We were certainly enchanted by the blanket of… Continue reading A snowy field day | Une journée enneigée sur le terrain

Geophysical mapping work at Gault | Travaux de cartographie géophysique à Gault
By | Par Alina Kostyuk La version française suit la version anglaise. Late this fall, ECOHYDROS assisted Professor Jeffrey Mackenzie and his team with geophysical mapping at the Gault Nature Reserve. This is the first time the lab participated in this kind of work, and the first time this was ever done at the reserve. We were using a method known… Continue reading Geophysical mapping work at Gault | Travaux de cartographie géophysique à Gault
Discovering our sapflow preliminary data | Découvrir nos données préliminaires de flux de sève
By | par: Olivier Grégoire La version française suit. Over the summer, we installed Implexx Sap Flow Sensors on four trees at the Gault Nature Reserve to study the vertical ecohydrological connectivity between groundwater and trees' evapotranspiration. To learn more about the significance of the relationship between surface water, groundwater and trees, and how we… Continue reading Discovering our sapflow preliminary data | Découvrir nos données préliminaires de flux de sève

Sampling Québec Rivers for Science Outreach Activities | Échantillonnage de plusieurs rivières québécoises pour des activités interactives de vulgarisation scientifique
On May 13th, 2025, a team of ECOHYDROS students visited five rivers between Montréal and Trois-Rivières. The team collected water samples from the Assomption, Yamachiche, Nicolet, Saint-François, and Richelieu rivers in preparation for hosting interactive science-outreach activities.
Extreme Rain: Tropical Storm Debby | Précipitation extrême: la tempête tropicale Debby
by | par: Alina KostyukTranslation by | traduit par: Florence Dancose Une version française de cet article suit la version anglaise. With the onset of climate change and global warming, extreme weather events, especially those relating to rain patterns, are a major concern. This is because warm air can hold more moisture than cold air,… Continue reading Extreme Rain: Tropical Storm Debby | Précipitation extrême: la tempête tropicale Debby
Tracking Fecal Coliforms: How Human Activities Affect Water Quality | Étudier les coliformes fécaux: l’effet des activités humaines sur la qualité de l’eau
This summer, I am studying the impact of extreme weather events on the water quality of Ours Creek, an important tributary of the Hurons River. Located in Montérégie, the river is labelled as having a very bad water quality in the province of Québec. I am analyzing 44 different water quality parameters, including total dissolved phosphorus, trace metals, and isotopic signatures, to better understand contaminant transport mechanisms. One of the parameters I’m focusing on is the concentration of fecal coliforms in the water, which serves as an indicator of contamination from fecal matter such as manure and sewage.
