More accurate aftershock zones reveal that the rupture areas of megathrust Aleutian–Alaska earthquakes are larger than we thought and partly overlap, in contradiction with the seismic gap hypothesis.
Cloud-to-ground lightning is found to be the most important controller of wildfire occurrence in the Artic tundra of Alaska from 2001 to 2019.
Increasing incidents of wildfires in the Arctic are not only thawing permafrost but changing the entire underlying structure of the region.
Miners in Alaska rerouted a river to search for gold. One hundred years later, the new channel is teaching scientists how rivers shape Earth.
Observations of cross-polar cap neutral winds near 240 km altitude stalling over short distances in the midnight sector near Poker Flat, Alaska, challenge the standard view of high-latitude dynamics.
Shrinking snowpack, thawing permafrost, and shifting precipitation patterns have widespread consequences. Can new technologies—and public policies—help communities adapt?
With infrastructure, experience, and a slice of the world’s largest snow biomes, Alaska is an essential research destination for NASA’s multiyear SnowEx campaign.
An ongoing project in northern Alaska is using pulses of laser light to monitor anthropogenic activity, ice quakes, and marine wildlife.
Long an anomaly among glaciers, advancing while most others shrank, Taku Glacier is starting to succumb to climate change, offering an unprecedented look at the onset of tidewater glacier retreat.
Fieldwork is revealing a history of landscape evolution over the past 5 million years that links climate change and river capture to critical mineral resources across the Alaska-Yukon border.
