A graphic shows a snow-capped mountain. The snowpack on top of the mountain is melting into a water glass to show that snowmelt makes its way to water users.

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.

Noa Randall and Rachel Allen are installing an optical turbidity sensor on the mudflats in Wellfleet harbor, to pair with the altimeter run by the Center for Coastal Studies.  The Herring River, which drains into Wellfleet Harbor, is slated to have its 100-yo dam removed in the next 6 months, with the potential to dramatically increase the sediment load and sus

COLORS OF THE CARBON RAINBOW

Not All Carbon is the Same

Scientists use color to classify carbon at different points in the carbon cycle based on carbon function, characteristics, and location. This creates a more descriptive framework than traditional "organic" and "inorganic" labels.

Climate change interacts with droughts in many ways. Some regions are experiencing warmer, drier conditions than they have in the past, leading to less rainfall (meteorological drought) or snowpack (snow drought). Over time, this can cause water sources like lakes, streams, and underground aquifers to dry up (hydrological drought).
