Drunken trees in a black spruce forest near Fairbanks, Alaska. As permafrost thaws, the ground subsides, and surface moisture conditions can become too wet for the trees to survive.

The rhizones pictured above are used to extract microbe samples from the sediment core. The microbes being studied are responible for producing and oxidizing methane.

Weather conditions in early April cultivate this rime ice on a precipitation gauge in Barrow. Rime forms when supercooled droplets collect and rapidly crystalize on a surface.
