The loss of the North American grassland biome. Once spanning more than 2 million square kilometers, we have lost over half of the world’s most imperiled ecosystem: the temperate grasslands. A map of North America shows the loss of the grassland biome from Canada to Mexico, largely contained within the central plains of North America.

In order to get accurate measurements, the Snow to Flow scientists collect several kinds of data using a few different tools. Evan and the team dig snowpits and collect snow depth, snow density, and weather data. They also place sensors across the snowpack to help the drones collect accurate data.

Snow water equivalent.png
This graphic shows how snow-water equivalent is calculated. A grey jar with a red lid dominate the graphic. Inside the jar is snow. On the top, the snow is loosely layered. On the bottom of the jar, the snow is more compact. Text alongside the right of the jar reads “snow depth.”

SnowtoFlowScienceTeam_withBanner.png
The Snow to Flow team is comprised of a “village” of remarkable scientists and engineers from the USGS Colorado Water Science Center, USGS National Uncrewed Systems Office (NUSO), and the University of Southern California - Viterbi School of Engineering. The team is pictured here at the Berthoud Pass, CO field site on April 18, 2022.
