Welcome to the Pratt Lab blog! Dr. Kerri Pratt is an assistant professor in the Departments of Chemistry and Earth & Environmental Sciences and faculty associate of the Program in the Environment at the University of Michigan. We study the chemical interactions of atmospheric trace gases, particles, clouds, and snow, with a focus on the Polar Regions and wintertime environments. Our interdisciplinary research has relevance to climate change, air quality, and human health. As an analytical chemistry lab, we primarily apply novel mass spectrometry techniques to our field research. We invite you to follow our adventures in (and outside!) the lab!

Heading back to Barrow!

From Saturday to Sunday, I (Prof. Pratt) flew back to Barrow, AK for air and snow sampling!  Here are a few photos from the trip:
"Baggage" (apparently someone really needs some soda!) being loaded during a stopover in Prudhoe Bay, Alaska

The "Barrow lead" opened in a big way on Sunday - approximately one month earlier and at a faster rate than previously. 
Watch a video of the dramatic lead opening on Feb. 23: Barrow Sea Ice Radar.
