Dr. Fereidoun Rezanezhad received the Technical University of Munich (TUM) Visiting Professor award. As part of this award, Fereidoun will visit the TUM in Spring 2019 to collaborate with Professors Kögel-Knabner and Carsten Muller on cold regions hydrogeochemistry research, to better understand the role of winter soil processes on the export of carbon and nutrients under non-growing season in cold region soil ecosystems. Congratulations, Fereidoun!

Philippe visited the Laboratoire the Physique Subatomique et des Technologies Associées (SUBATECH) in Nantes on January 28-29. He met with members of the Radiochemistry group, including Dr. Catherine Landesman and Dr. Abdesselam Abdelouas, to discuss joint research projects using environmental radioisotopes. He presented a talk entitled “What’s in a Name: Ecohydrology – Waterloo Style”.

Nitrous oxide (N₂O) emissions from inland waters remain a major source of uncertainty in global greenhouse gas budgets. In the paper published in the journal Global Change Biology a novel mechanistic modeling approach is presented to explicitly predict the N₂O production and emissions via nitrification and denitrification in rivers, reservoirs, and estuaries. The global inland water N₂O emissions estimated with this approach are 10-20 Gmol per year, with reservoirs releasing the most N₂O per unit surface area.

The Ecohydrology Research Group (ERG) and Qatar University are collaborating on a project to study the fate of petroleum-derived hydrocarbons in coastal aquifers of arid regions.

Ecohydrology Research Group members, Dr. Fereidoun Rezanezhad and Konrad Krogstad, together with Grant Jensen from Waterloo's Department of Biology, are featured in a news article presented by the Water Institute

This week, Ecohydrology Group members are presenting their research at the 2018 AGU Fall Meeting (December 10-14, 2018) in Washington, D.C. With nearly 24,000 attendees, the American Geophysical Union (AGU) Fall Meeting is the largest Earth and space science meeting in the world.

Adrian Mellage has successfully defended his PhD thesis titled "Hydrobiogeophysics: Linking geo-electrical Properties and Biogeochemical Processes in Shallow Subsurface Environments". Adrian completed his PhD with the Ecohydrology Research Group, at the University of Waterloo.

Environmental Science and Technology articles ASAP (as soon as publishable) now features a publication by Ecohydrology researchers Adrian Mellage, Laureline Vallée, Fereidoun Rezanezhad and Philippe Van Cappellen in collaboration with researchers from nanotechnology. The paper titled “Sensing Coated Iron-Oxide Nanoparticles with Spectral Induced Polarization (SIP): Experiments in Natural Sand Packed Flow-Through Columns” focuses on sensing engineered nanoparticles, designed for targeted hydrocarbon remediation, using spectral induced polarization (SIP).

A new paper, co-authored by Drs. Stephane Ngueleu, Fereidoun Rezanezhad and Philippe Van Cappellen, has been published in Journal of Contaminant Hydrology. The article, titled " Sorption of benzene and naphthalene on (semi)-arid coastal soil as a function of salinity and temperature ", was written in collaboration with Dr. Riyadh Al-Raoush from Qatar University.
