SIOUX CITY -- John Helms, assistant professor of chemistry at Morningside College, co-authored a research paper that was recently published in the journal Global Biogeochemical Cycles.

The paper, “Removal of Atmospheric Ethanol by Wet Deposition,” focused on the concentrations of ethyl alcohol measured in rainwater collected in Maine, Iowa, North Carolina, Virginia, Washington, Texas, United Kingdom, Greece and Brazil. It also highlights the atmospheric impact of the increased production and use of ethanol biofuels.

Helms has been a Morningside College faculty member since 2014. He has a doctorate in chemistry from Old Dominion University in Norfolk, Va.
