Résumé
Globally, streams represent major CO2 emitters, accounting for approximately 70% of the total flux from inland waters. Hence, a proper understanding of carbon dioxide (CO2) uptake and emissions from streams is crucial for accurately estimating aquatic global carbon emissions. However, diurnal dynamics of these fluxes are still not comprehensively quantified, contributing to a high uncertainty in regional and global carbon budgets. Within the EuroRun project, the 1st Collaborative European Freshwater Science Project for Young Researchers, we aimed to assess spatial and seasonal variability of day- and night-time CO2 fluxes of 34 streams across 11 European countries. CO2 fluxes were measured with drifting flux chambers once per season at midday and midnight. The median CO2 fluxes during the day amounted to 1.4 µmol m-2 h-1 (IQR 0.5 to 3.1) and during the night to 2.1 µmol m-2 h-1 (IQR 0.95 to 3.75). The CO2 fluxes during night exceeded those during day by up to eight times. Interestingly, these differences occurred throughout all seasons and showed no latitudinal patterns. Our results highlight the importance of night-time fluxes to accurately assess CO2 fluxes from streams. As most studies are performed during the day, our survey indicates that global carbon budgets are currently underestimating the amount of CO2 released by streams.
