Short summary
We measured the impacts of permafrost disturbances, namely retrogressive thaw slumps, on the carbon balance in a high Arctic tundra ecosystem. We used a novel approach (dual eddy covariance sampling strategy) to measure continuous CO2 exchange from undisturbed and disturbed tundra simultaneously. We further validate eddy covariance fluxes with portable chamber measurements. Our findings show that permafrost disturbances change the carbon balance from being a net sink to a net source.
