Roads, bridges, pipelines and other types of infrastructure in Alaska and elsewhere in the Arctic will deteriorate faster than expected due to a failure by planners to account for the structures’ impact on adjacent permafrost, according to research by a University of Alaska Fairbanks Geophysical Institute permafrost expert and others. The researchers say planners must […]
To the delight of the local mosquitoes, Nicholas Hasson steps through a tangle of prickly spruce branches while wearing a backpack that holds a scientific instrument. Hasson is walking as straight a line as he can through a Fairbanks subdivision built in the boreal forest. Hasson studies permafrost at the University of Alaska Fairbanks. He […]
High summer is here in middle Alaska. North of Fairbanks, in bright sunshine, alder flycatchers are perched in spruce tops, just arriving from Bolivia and Peru. A few steps away, accompanied by the smell of sulfur, dozens of carrion flies buzz on and above a moose carcass. Permafrost expert Tom Douglas has led me […]
A University of Alaska Fairbanks-led research team has developed a way to use satellite images to determine the amount of methane being released from northern lakes, a technique that could help climate change modelers better account for this potent greenhouse gas. By using synthetic aperture radar, or SAR, researchers were able to find a […]
