A recent paper presents new insights into the relationship between soil CO2 fluxes and soil moisture
Today, we held our first in-person research seminar since the start of the pandemic. About 40 people gathered to hear Dr. Lewis Alcott present his seminar entitled “Phosphorus and climate through time and sampling uncertainties in the past and present”. Dr. Alcott is currently a Hutchinson Environmental Postdoctoral Fellow at Yale University working on the characterization and implications of the spatial and temporal variability of GHG sources. He holds a PhD degree from the University of Leeds.
This year’s theme of the 9th International Conference on Water Resources and Environment Research (ICWRER) is Bridging the Gaps of Interdisciplinary Sustainability for Complex Water and Environmental Systems. The Conference was held virtually on April25 to 27. Philippe gave an invited talk in the session on Eco-water Security and Smart Water Management in Large River Basins, chaired by Profs. Jun Xia and Gangsheng Wang. The topic of the talk was Biogeochemical Impacts of River Damming: Lessons Learned and Implications for Watershed Management.
A new paper reconstructs the agricultural phosphorus (P) inputs across the province of Ontario since the 1960s. The first author of the paper, entitled Agricultural phosphorus surplus trajectories for Ontario, Canada (1961-2916), and erosional export risk, is former ERG MSc student Tamara Van Staden. Co-authors include the ERG members Chris Parsons, Zahra Akbarzadeh, and Philippe Van Cappellen, as well as their colleagues Kim Van Meter and Nandita Basu.
The oxidation of Fe(II) plays an important role in the biogeochemical cycling of redox-sensitive elements and the fate and transport of pollutants in subsurface environments. In a joint study by researchers from ERG and China University of Geosciences, the kinetics of aqueous Fe(II) oxidation by O2 were measured at variable pH in the presence of riboflavin and desferrioxamine B as representative flavins and siderophores, respectively. The study closes important gaps in our understanding of the reaction mechanisms involved.
Ecohydrology researchers presented virtually at this year's European Geosciences Union (EGU), which was held from April 19th to 30th. The following works have been presented:

Ecohydrology Research Group members Dr. Philippe Van Cappellen, Dr. Fereidoun Rezanezhad, and Dr. Adrian Mellage co-authored a new paper that was recently published in Science of the Total Environment. The paper presents the results from flow-through experiments where Spectral Induced Polarization (SIP) was successfully implemented to monitor transport of cobalt ferrite nanoparticles (CoFe-NPs) coated with Pluronic, anamphiphilic polymer through natural aquifer sand-packed columns.
