Daniele Tonina Co-Authors Publication to Better Predict Stream Contribution to Greenhouse Emissions
May 14, 2021
University of Idaho Center for Ecohydraulics Research Associate Professor Daniele Tonina co-authored a publication on the role streams and rivers play in contributing large amounts of greenhouse gases around the world. The publication, “Controls on Nitrous Oxide Emissions From the Hyporheic Zones of Streams,” covers emissions of nitrous oxide, a greenhouse gas commonly found in streams and known for a warming potential 300 times that of carbon dioxide..
Daniele and fellow researchers from Yale University, Italy’s University of Trento and Texas A&M University found nitrous oxide, known as an ozone-depleting substance, in stream sediments with results showing a distinct pattern of generation and consumption dictated by the amount of time water spends within the bed material of streams and rivers.
“This information will help better predict and constrain greenhouse gas emissions from streams and rivers,” said Daniele. “Nitrous oxide is also responsible for warming the planet temperature.”
Most emissions are related directly or indirectly to agricultural practices. Nitrogen-rich fertilizer stimulates production in soils and downstream systems subject to agricultural runoff.
