Landscape process domains drive patterns of CO 2 evasion from river networks
Abstract Streams are important emitters of CO 2 but extreme spatial variability in their physical properties can make upscaling very uncertain. Here, we determined critical drivers of stream CO 2 evasion at scales from 30 to 400 m across a 52.5 km 2 catchment in northern Sweden. We found that turbul...
