  abstract = {{T}he {R}ed {R}iver ({V}ietnam) is representative of a south-east {A}sian river system, strongly affected by climate and human activities. {T}his study aims to quantify the spatial and seasonal variability of {CO}2 partial pressure and {CO}2 emissions of the lower {R}ed {R}iver system. {W}ater quality monitoring and riverine p{CO}(2) measurements were carried out for 24 h at five stations distributed along the lower {R}ed {R}iver system during the dry and the wet seasons. {T}he riverine p{CO}(2) was supersaturated relative to the atmospheric equilibrium (400 ppm), averaging about 1589 +/- 43 ppm and resulting in a water-air {CO}2 flux of 530.3 +/- 16.9 mmol m(-2) d(-1) for the lower {R}ed {R}iver. p{CO}(2) and {CO}2 outgassing rates were characterized by significant spatial variation along this system, with the highest values measured at {H}oa {B}inh station, located downstream of the {H}oa {B}inh {D}am, on the {D}a {R}iver. {S}easonal p{CO}(2) and {CO}2 outgassing rate variations were also observed, with higher values measured during the wet season at almost all sites. {T}he higher river discharges, enhanced external inputs of organic matter from watersheds and direct inputs of {CO}2 from soils or wetland were responsible for higher p{CO}(2) and {CO}2 outgassing rates. {T}he difference in p{CO}(2) between the daytime and the night-time was not significant, suggesting weak photosynthesis processes in the water column of the {R}ed {R}iver due to its high sediment load.},
