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 […]
Altruistic helping — the act of giving away something desirable, even at a cost to oneself — is perhaps no more evident than when it comes to food. Human adults often respond to hungry people, whether through food banks or fundraisers, or by simply handing over their lunch. But when, and how, does […]
University of Alaska Fairbanks scientists are developing a new method to predict ecosystem change in Interior Alaska, and their techniques could prove useful elsewhere in the world. The study uses real-time water data, rather than simulations, to predict ecosystem “tipping points.” “We’re pretty good, as ecosystem ecologists, at using stream chemistry to tell us […]
By 2099, winds along Alaska’s northwestern coasts are projected to grow stronger, according to a new study from the University of Alaska Fairbanks. To understand past and future winds, programmer Kyle Redilla, of UAF’s International Arctic Research Center, and Sarah Pearl, an undergraduate from Dartmouth College, analyzed over 30 years of data from 67 airports […]
