National Science Foundation funds creation of research observatory at Gakona

Posted April 6th, 2021 for Geophysical Institute April 06, 2021 / Rod Boyce A five-year, $9.3 million National Science Foundation grant will allow the University of Alaska Fairbanks Geophysical Institute to establish a new research observatory dedicated to exploring Earth’s upper atmosphere and geospace environment. The Subauroral Geophysical Observatory for Space Physics and Radio Science will be housed at the High-frequency Active Auroral Research Program site in Gakona, Alaska.  The facility’s 33-acre Ionospheric Research Instrument will be the centerpiece of the new observatory. A second NSF-funded project will add a lidar at the site, which will allow the study of other regions of the upper atmosphere. A lidar sends pulses of laser light to determine the composition, temperature and structure of regions of the upper atmosphere from 90 to 150 kilometers.

Study of Redoubt and other volcanoes improves unrest detection

 E-Mail Volcanologists do what they can to provide the public enough warning about impending eruptions, but volcanoes are notoriously unpredictable. Alerts are sometimes given with little time for people to react. That may soon change. Work led by research assistant professor Társilo Girona, with the University of Alaska Fairbanks Geophysical Institute, has revealed a method by which scientists and the public can have perhaps years of advance warning about a potential eruption. The solution lies in regular and widespread monitoring of the radiant temperature of a volcano s flanks before the appearance of any of the usual warning signs, such as glacier melting, sulfur odors, increased gas emissions, quaking and deformation.
