The current state of CO2 flux chamber studies in the Arctic tundra: a review
The Arctic tundra plays an important role in the carbon cycle as it stores 50% of global soil organic carbon reservoirs. The processes (fluxes) regulating these stocks are predicted to change due to direct and indirect effects of climate change. Understanding the current and future carbon balance ca...

The Arctic tundra plays an important role in the carbon cycle as it stores 50% of global soil organic carbon reservoirs.
