  • Investigating the dynamics that reshape permafrost environments
    on June 25, 2022 at 9:49 am

    When permafrost thaws, water can flow more quickly through the ground, creating a complex subsurface flow system. Researchers at the Barrow Environmental Observatory in Alaska gained insight into this process by taking daily measurements of the electrical resistivity of the ground. The results show that vegetation and the snowpack that accumulates on the vegetation in winter control the temperatures of the ground and the flow of water in the ground. Where snow accumulates, ground temperatures […]
