Hunga Volcano Eruption Provides an Explosion of Data

By Rod Boyce | Geophysical Institute on May 14, 2022   Featured, Science/Education  

Hunga Volcano Eruption Provides an Explosion of Data

The massive Jan. 15, 2022, eruption of the Hunga submarine volcano in the South Pacific Ocean created a variety of atmospheric wave types, including booms heard 6,200 miles away in Alaska. It also created an atmospheric pulse that caused an unusual tsunami-like disturbance that arrived at Pacific shores sooner than the actual tsunami. Those are […]

Major 2020 Alaska Quake Triggered Neighboring 2021 Temblor

Major 2020 Alaska Quake Triggered Neighboring 2021 Temblor

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 […]

Precipitation Helped Drive Distribution of Alaska Dinosaurs

Precipitation Helped Drive Distribution of Alaska Dinosaurs

Precipitation more than temperature influenced the distribution of herbivorous dinosaurs in what is now Alaska, according to new research published this month. The finding, published April 2 in the journal Geosciences, discusses the distribution of hadrosaurids and ceratopsids — the megaherbivores of the Late Cretaceous Period, 100.5 million to 66 million years ago. The work […]

Earth’s Atmosphere May be Source of some Lunar Water

Earth’s Atmosphere May be Source of some Lunar Water

Hydrogen and oxygen ions escaping from Earth’s upper atmosphere and combining on the moon could be one of the sources of the known lunar water and ice, according to new research by University of Alaska Fairbanks Geophysical Institute scientists. The work led by UAF Geophysical Institute associate research professor Gunther Kletetschka adds to a growing body of research about […]

UAF Researcher Part of Team that Proves Mercury has Magnetic Storms

UAF Researcher Part of Team that Proves Mercury has Magnetic Storms

An international team of scientists has proved that Mercury, our solar system’s smallest planet, has geomagnetic storms similar to those on Earth. The research by scientists in the United States, Canada and China includes work by Hui Zhang, a space physics professor at the University of Alaska Fairbanks Geophysical Institute. Their finding, a first, answers […]

UAF Students Aid Bristol Bay Communities in Coastal Erosion Research

UAF Students Aid Bristol Bay Communities in Coastal Erosion Research

University of Alaska Fairbanks students will return to several Bristol Bay communities this year to continue quantifying and mapping widespread coastal erosion. Students in the Arctic Coastal Geoscience Lab of the UAF Geophysical Institute have been trudging through mud and scrambling over the debris of slumped-off bluffs in the region since 2016. Their research is […]

Poker Flat rocket launch to study energy movement during aurora

By Rod Boyce | Geophysical Institute on Mar 25, 2022   Featured, Science/Education  

Poker Flat rocket launch to study energy movement during aurora

Two sounding rockets are scheduled to launch from Poker Flat Research Range just minutes apart in an experiment aimed at learning how energy is transferred and dissipated during auroral displays. The findings could increase the understanding of factors affecting satellites in low Earth orbit. The NASA-funded Ion-Neutral Coupling during Active Aurora experiment could launch from […]

NASA rocket launches from Poker Flat in search of aurora answers

NASA rocket launches from Poker Flat in search of aurora answers

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 […]

Scientists aim to improve sea ice predictions’ accuracy, access

Scientists aim to improve sea ice predictions’ accuracy, access

Sea ice predictions have improved markedly since the founding of an international forecasting and monitoring network 14 years ago. “These forecasts are quite encouraging in their increasing accuracy,” said Uma Bhatt, an atmospheric sciences professor at the University of Alaska Fairbanks Geophysical Institute. Bhatt spoke about the Sea Ice Prediction Network at the American Geophysical […]
