University of Alaska Fairbanks researchers have developed a way to use radar to detect open water zones and other changes in Alaska’s frozen rivers in the early winter. The approach can be automated to provide current hazard maps and is applicable across the Arctic and sub-Arctic. Many Alaskans, especially in rural parts of the state, […]
Research testing new technology to more effectively locate polar bear dens across the Arctic is showing promising results. Researchers from Simon Fraser University and Brigham Young University (BYU), collaborating with Polar Bears International, hope that improving detection tools to locate dens—which are nearly invisible and buried under snow—will help efforts to protect mother polar bears […]
Specialized portable radar could serve as an early warning system to reduce risk for humans working on shorefast sea ice, according to a recently published study. The researchers suggest that use of portable interferometric radar can quickly reveal small changes that could indicate imminent movement or detachment of the ice, which is important as climate […]
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 […]
