Watershed biogeochemistry in cold but warming regions
Why study the arctic?
Global annual average temperature has changed.warmer
The most exchange is happening in Arctic
Permafrost: not so rock solid anymore
Ice wedge, active flayer detachment
Warming and Slope stability
Big rainfall, the soil moves down slopes
Climate change will alter:
Precipitation amounts, type and timing
Runoff volumes and timing, sub surface flow
Why does arctic biogeochemistry matter?
Local importance: water quality, fisheries
Global importance: feedback on global cycle and climate
Nitrate: An important nutrient.
Nitrate and other stuff g
