Wildfire and Alaskan Permafrost
Deploying geophysical equipment in the Nome Creek (AK) area to assess the effect of wildfire on permafrost. Small electrical signals are injected into the ground through metal stakes connected to the orange cable in the foreground. The measured response is used to detect belowground permafrost conditions.
