EN Virtual Seminar
September 23, 2020 @ 4:00 pm - 5:00 pm
The Environmental Division of Chemical Institute Canada (EN) brings together members in the field of environmental sciences and engineering. Together with the Environmental Chemistry program in the Department of Chemistry at the University of Toronto, we are pleased to introduce a new series of virtual talks covering a wide range of topics in environmental chemistry, including in the atmospheric, terrestrial, freshwater, marine and Arctic environments. Talks will be held on Wednesdays at 4:00 pm (ET). Participation is free of charge for everyone.
Speaker: Feiyue (Fei) Wang (Centre for Earth Observation Science, University of Manitoba)
Abstract: Cryospheric chemistry across the ocean-sea ice-atmosphere interface
Cryo-reactions (chemical reactions at freezing temperatures) are well known to play a major role in atmospheric chemistry. Evidence is mounting that the Earth’s surface cryosphere is also a much more chemically and biogeochemically active environment than previously thought. This presentation will provide a synopsis of cryo-reactions in the Arctic marine cryosphere, highlighting their role in the cycling of CO2, mercury, and oil spills across the ocean-sea ice-atmosphere interface in a changing climate. New research initiatives and collaborative opportunities at the Sea-ice Environmental Research Facility and Churchill Marine Observatory will also be discussed.
