Abstract:
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.
Dr. Fei Wang is Professor and Canada Research Chair (Tier 1) in Arctic Environmental Chemistry at the University of Manitoba. He directs the Ultra-Clean Trace Elements Laboratory (UCTEL), leads the Sea-ice Environmental Research Facility (SERF), and is Chief Scientist of the Ocean-and-Sea-Ice Mesocosm (OSIM) of the Churchill Marine Observatory (CMO).
