Ocean temperatures in the Bering Strait and heat transport through the region have increased over the past 20 years. New modeling using a range of temperatures shows that reduced regional September sea ice occurs one to three months after a heat increase. That’s the preliminary finding of research by University of Alaska Fairbanks doctoral student […]
Earthquakes have a well-known and easily recognizable connection to volcanoes. The sudden onset of ground shaking can indicate near-term or imminent volcanic activity. Volcanic tremors, however, are difficult to detect. These are semi-continuous seismic or acoustic signals, or both, that continue for just a few seconds or persist for a year or more. They, like earthquakes, carry […]
The second NASA sounding rocket of the season headed into Earth’s upper atmosphere from Poker Flat Research Range shortly after midnight Thursday, carrying a payload of science instruments. It was the second launch in two nights at the rocket range, owned by the University of Alaska Fairbanks Geophysical Institute and operated under a contract with NASA’s Wallops Flight […]
A two-stage NASA sounding rocket flew skyward shortly after midnight Wednesday carrying science instruments to gather data about the solar wind’s behavior. The experiment, named Dissipation, is aimed at learning how charged solar wind particles dissipate their energy in the high-latitude ionosphere-thermosphere. That region is about 62 to 186 miles above the surface and at latitudes above 65 […]
