A study of two powerful earthquakes in adjacent areas of the Alaska Peninsula in 2020 and 2021 shows a connection between the two. It also suggests they may be a part of an 80-year rupture cascade along the fault. The research was published Wednesday in the journal Science Advances in a paper jointly led by University […]
Alaska’s coastal waters are some of the most commercially valuable and productive ecosystems on the planet. Ocean acidification—a decrease in ocean pH caused by increasing concentrations of carbon dioxide—is expected to impact these ecosystems, but very little is known about how it could alter nearshore environments. Nearshore ecosystems provide habitat and serve as a nursery […]
A NASA Black Brant IX sounding rocket soared high out of Poker Flat Research Range north of Fairbanks at 2:27 a.m. Saturday to learn more about pulsating aurora. The Loss through Auroral Microburst Pulsations, or LAMP, experiment seeks to determine whether the pulsating aurora is connected to another phenomenon called microbursts, higher-energy electrons from the Earth’s magnetosphere driven […]
The research vessel Sikuliaq navigated among and around the chunks and slabs of Arctic sea ice above Alaska for several weeks on two voyages this fall, breaking through frozen slabs when it had to just as its sturdy hull is designed to do. Satellite imagery produced at the Geographic Information Network of Alaska, or GINA, at the University […]
