Publication Finds That Permafrost Presence Results in Warmer Headwater Streams Release Date:
January 13, 2021
Permafrost thaw is occurring across the Arctic with potential consequences for hydrology, ecosystems, humans, and wildlife. A team of scientists from the U.S. Geological Survey Alaska Science Center, the National Park Service, and the Department of Energy Oak Ridge National Laboratory are collaborating to understand the impacts of warming on the ecosystems in the Noatak Preserve in Alaska.
In a recent study, scientists monitored temperature across 11 headwater streams in Noatak National Preserve in northwest Alaska. They used groundwater-heat flow modeling and stream temperature data to demonstrate how permafrost presence and thaw impacts water temperatures in headwater streams. A new publication
