Thawing permafrost is literally shifting the ground beneath our feet. Guido and his team are using high-resolution aerial and satellite imagery to document landscape change and thaw processes on the Seward and Baldwin peninsulas. Learn about the Perma-X research, the free Arctic Landscape Explorer web tool, and what lies ahead as the big thaw unfolds.
