Spring Runoff is Older Than You Think

DRI’s Rosemary Carroll, Research Professor of Hydrology, co-authored a new study that found spring runoff in mountains across the Western U.S. is much older than previously known. Using advanced dating techniques, the research discovered that melting mountain snowpacks first replenish groundwater reserves before filling springs several years later. This means that the water relied on by communities across the West takes over five years from snowflake to streamflow. The research has implications for water management and our understanding of the changing dynamics of water availability.

Graduate Student Winners of the Annual Poster Presentation Session

On Friday, April 25th, 21 graduate students presented their research at DRI’s Reno campus for the annual poster presentation session. Organized by Kathleen Rodrigues, PhD, Assistant Research Professor of Luminescence, the poster session offers an opportunity for DRI-affiliated graduate students to network with each other and with DRI faculty, hone their presentation skills, and showcase the research they’re working on in pursuit of their degrees.

Long Science in the Nevada Bristlecone Preserve

Ancient bristlecone pines have been collecting data for us for millennia. Anne Heggli's research aims to provide a nearly microscopic look at how the climate in the Great Basin is changing, from hour to hour and season to season. With scientific monitoring equipment positioned from the floor of the Great Basin’s Spring Valley up to the peak of Mount Washington, her project examines temperature fluctuations, atmospheric information, and snowpack insights across the region’s ecosystems.

Meet Cayenne Engel

Cayenne Engel, M.Sc., is a Staff Research Scientist in urban climate adaptation who joined DRI in September 2024. Based at DRI’s Las Vegas campus, she is dedicating her time to assessing and expanding the region’s urban tree canopy to bring relief to communities burdened by temperatures that regularly soar above 100° Fahrenheit. In the following interview, Engel shares her passion for public service-oriented research, how Nevada’s unparalleled landscape lured her west, and her love for intricate puzzles.

DRI Holds Water Panel at Nevada State Legislature

On March 27, DRI scientists gathered at the State Capitol to illuminate work that supports Nevada’s communities and landscape. With more than 600 scientists, engineers, students, and staff across our Reno and Las Vegas campuses, we conducted more than $52 million in sponsored research focused on improving peoples’ lives in 2024 alone.

What’s in the Burnt Remains of the LA Wildfires?

DRI scientists deployed to Los Angeles to collect ash, soil, and dust samples from burn zones in the hopes of illuminating the unique risks of wildland-urban fires. These urban fires presented a unique opportunity to understand how materials like plastics, metals, and even lithium batteries from electric cars can transform into environmental contaminants when they burn.

OpenET’s New CEO, Sara Larsen, Discusses the Future of the Revolutionary Water-Monitoring Initiative

OpenET, a nonprofit initiative focused on improving water management with accessible, satellite-based evapotranspiration (ET) data, has welcomed Sara Larsen as the new CEO. DRI sat down with Sara to discuss what makes the initiative unique, her plans for the organization, and how OpenET can help address the biggest challenges in water management.
