Two NASA aurora research rockets launched from Poker Flat Research Range earlier this month provided good data for learning more about the fastest observable variations of the solar wind-driven light displays. One rocket gathered information about flickering aurora, and the other gathered data about fast-pulsating aurora. Flickering auroras are fast, localized and associated with higher-frequency […]
Mount Churchill stands in a white corner of the Alaska map, deceptive in its cold, windblown silence. At least twice in the last few thousand years, the peak’s ice-covered caldera has spewed ash that reached as far as Ireland and piled up to force northern animals out of the territory. The Alaska Highway and other […]
Scientists have produced the first remote sensing analysis of how water clouded by sediment in glacier meltwater moves on the surface of Kachemak Bay. The bay on Alaska’s Kenai Peninsula is home to a rich variety of marine life that can be affected by the sediment. Work led by Lea Hartl of the Alaska Climate Research […]
An early exit of Alaska’s spring snow means more acreage could burn during the coming wildfire season, which begins when the snow melts off, says new research from the University of Alaska Fairbanks “The most significant finding is that during many of the largest, most extreme fire seasons, we had early snowoff,” explained Peter Bieniek, […]
