- 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
- darken surfaces
- 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
- contributors to melting of permafrost
- oil + gas production + transport (melt permafrost)
- 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
- summer
- minimal relief + glacial deposits
- Human Factors
