Researchers Take on Atmospheric Effects of Arctic Snow Melt
Researchers at the University of Alaska Fairbanks’ Geophysical Institute are exploring the changing chemistry of the Arctic’s atmosphere to help answer the question of what happens as snow and ice begin to melt.
The research, led by chemistry professor William R. Simpson, is concerned with the Arctic’s reactive bromine season, which is the period of time when bromine is consuming ozone, producing bromine monoxide and oxidizing mercury.
Reactive bromine events occur during Arctic springtime, when temperatures are low and sea ice is snow-covered. As springtime transitions to summer, with temperatures climbing above freezing and snowpack melting, these events cease and atmospheric bromine quantities become low.
Peter K. Peterson, one of Simpson’s student researchers, noted a predictive application of the research: An increased understanding of bromine reactivity could help scientists figure out how “the atmospheric composition in the Arctic might respond to rapidly changing sea ice conditions.”
