More needs to be done to better understand rapidly changing Arctic landscapes that are sinking as climate-driven permafrost thaw penetrates deeper, according to new research by University of Alaska Fairbanks scientists and others. International climate monitoring organizations have no uniform standard for measuring ground subsidence, leading to an underestimation of thaw depth and therefore an […]
Three NASA sounding rockets are set to launch from Poker Flat Research Range as early as Tuesday to learn more about three types of aurora — black, flickering and fast-pulsating. The launch window is Jan. 21 through Feb. 5. The University of Alaska Fairbanks Geophysical Institute owns Poker Flat, located at Mile 30 Steese Highway, […]
New research shows that three sites spread along an approximately 620-mile portion of today’s Denali Fault were once a smaller united geologic feature indicative of the final joining of two land masses. That feature was then torn apart by millions of years of tectonic activity. The work, led by associate professor Sean Regan at the […]
Most electrons that create the aurora have a moderate amount of energy, but scientists want to know more about how electrons on either side on that scale — more and less energy — affect the electrical properties of the ionosphere, the part of Earth’s upper atmosphere that is ionized by the sun. These properties define […]
