  • Arctic Tundra Water Cycle
    • Human Factors
      • oil + gas production + transport (melt permafrost)
        • contributors to melting of permafrost
          • construction of oil + gas installations + infrastructure
          • dust along side of road
            • darken surfaces
              • increase absorption of sunlight
          • removal of vegetation
            • insulates permafrost
        • increase run-off + river discharge
          • increase risk of flooding
        • increased evaporation in summer from large areas of wetland
        • ***** mining creates artificial lakes
          • disrupt drainage
          • expose permafrost to further melting
        • drainage disrupted by road construction
    • Physical Factors
      • minimal relief + glacial deposits
        • prevent drainage
        • contribute to water logging in summer
          • soil highly saturated
      • low permeability
        • due to permafrost + crystalline rocks
      • water stored as ground ice in permafrost for most of the year
        • summer
          • active layer thaws
          • water pools fill landscape
            • poor drainage - cant infiltrate soil
