New Research Solves 200 Year Volcanic Mystery

DRI scientists Joe McConnell and Nathan Chellman are co-authors on a new study that sheds light on a historical mystery that has plagued historians and scientists alike for nearly two centuries. Using Arctic ice core records, the team identified the volcano responsible for an enormous eruption in 1831 that caused global cooling of around 1°C, leading to crop failures and famines around the world.

Meet Tyler Doane

Tyler Doane, Ph.D., started in May 2024 as Assistant Research Professor in the Division of Hydrologic Sciences. He works remotely from Cleveland, Ohio, where his wife teaches bioethics at Case Western Reserve University’s medical school. Doane is a geomorphologist who received his Ph.D. at Vanderbilt University before completing a postdoctoral position at Indiana University, Bloomington. In the this Behind the Science interview, Doane talks about his interest in applying math to describe scientific phenomena, his interest in embracing noise and chaos to understand Earth systems, and his favorite method for coming up with new research questions.

Measuring Colorado River Evaporation from Reservoirs

DRI is advancing water management in the Colorado River basin with support from the National Science Foundation's Southwest Sustainability Innovation Engine (SWSIE) and the Governor's Office of Economic Development. Partnering with Hydrosat, DRI uses high-resolution satellite thermal imaging to enhance evaporation estimates from key reservoirs, ensuring better resource planning amidst drought and population growth.

Tracking the Restorative Effects of Good Fire

A few miles south of Yosemite’s famed Glacier Point, ringed by striking granite domes, lies the Illilouette Basin. This small stretch of the Sierra Nevada Mountains has become a sort of fire laboratory, a place where natural wildfires have been allowed to burn since 1972. In contrast with the long-supported program of fire suppression that has dominated American forests since the late 19th century, resulting in dense and unhealthy forests, the Illilouette Basin’s story is about the benefits that natural fire can bring to the landscape.

Groundwater is Key to Protecting Global Ecosystems

New research identifies ecosystems around the world that could be threatened by declining groundwater levels. The research, published July 17 in Nature, is the first time that groundwater-dependent ecosystems have been mapped on a global scale. Led by scientists from The Nature Conservancy and DRI, the global effort brought researchers together from universities, non-profit organizations, and institutions from seven countries.

Western Agricultural Communities Need Water Conservation Strategies to Adapt to Future Shortages

Relying on water storage won’t be enough to make up for declines in future water availability under a changing climate, new study shows. Beatrice Gordon, lead author of the study and sociohydrologist and postdoctoral researcher at DRI, says the research is needed to inform water management at the local level, where most decisions are made.
