[en] The transport of excess atmospheric CO2 (defined as the fraction of dissolved
inorganic carbon (DIC) that can escape as CO2 to the atmosphere due to water-air equilibration),
by the five rivers entering the Scheldt estuary is investigated. Excess CO2 originates
from both respiration in the soil and the river and represents 10 % of the DIC and 6 % of the
total carbon input into the estuary. The ventilation of this CO2 in the estuary is however a
minor contribution (10 %) to the total estuarine emission to the atmosphere, compared to
heterotrophic activity and acidification due to nitrification within the estuarine zone.
