Winter vehicle travel can cause long-lasting damage to the tundra, according to a new paper by University of Alaska Fairbanks researchers published in the journal Ecological Applications. Scars from seismic surveys for oil and gas exploration in the Arctic National Wildlife Refuge remained for decades, according to the study. The findings counter assertions made […]
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 […]
Volcanoes can pulse and inflate before they erupt. Earthquakes can tear the ground along fault lines like a losing raffle ticket. Satellites can see these landscape events from space, and, now, a new tool will help scientists to better visualize them. This spring, a team of scientists at the University of Alaska Fairbanks and […]
