Abstract Land-to-water hydrological connections represent a key regulatory mechanism of carbon transport, controlling carbon dioxide (CO2) emissions from lakes; however, as of yet, there is no assessment of its role at a pan-Arctic scale across large climatic and topographical gradients. We hypothesized that hydrologically well-connected lakes in wetter regions are CO2 sources fueled by stronger lateral fluxes of external carbon relative to drier regions.
