报告简介：

     _{Streams and rivers emit petagrams of CO2, yet there is little known about how discharge variability impacts stream CO2 at broad scales. This research analyzed changes of pCO2 and CO2 efflux with discharge in 813 conterminous US streams and rivers. Half of the streams and rivers (49%) showed positive pCO2–discharge responses, while significantly more (80%) showed positive CO2 efflux–discharge responses.}
