Abstract

Globally, inland waters emit over 2 Pg of carbon (C) per year as carbon dioxide (CO2), of which the majority originates from streams and rivers. Despite the global significance of fluvial CO2 emissions, little is known about their diel dynamics. We present the first large-scale assessment of day- and night-time CO2 fluxes at the water-air interface across European streams. Fluxes were directly measured four times throughout one year using drifting chambers. Median CO2 fluxes amounted to 1.4 and 2.1 mmol m-2 h-1 at midday and midnight, respectively, with night fluxes exceeding those during the day by 39%. Diel CO2 flux variability was mainly a...  more
