Energy fluxes have been measured at one static summer site located over typical Moist Acidic Tussock tundra (MAT) and a mobile tower has been used to characterize three other ecosystem types (Shrub tundra (SHRUB), Moist Non-Acidic (MNT) tundra, and a Sphagnum dominated Tundra (MOSS)).

The Shrub tundra type represents an ecosystem type that is likely to be dominant in predicted climate change scenarios and field results already show that sensible heat fluxes in the shrub tundra are greater than that at the typical MAT site. The increase in sensible heat fluxes over this important vegetation type could lead to a positive feedback on climate change by producing warmer temperatures.

The MNT site represents an important tundra type that differs in its surface energy exchange and permafrost dynamics.

Finally the MOSS site represents a previously undocumented ecosystem type that will elucidate how vegetation may modulate interactions between climate and permafrost.
