  abstract = {{R}iverine transport of organic carbon from terrestrial ecosystems to the oceans plays an important role in the global carbon cycle. {T}he {R}ed {R}iver is located in {S}outheast {A}sia where river discharge, sediment loads and fluxes of elements (carbon, nitrogen and phosphorus) associated with suspended solids have been dramatically altered over past decades as a result of reservoir impoundment and land use, population, and climate change. {D}issolved organic carbon ({DOC}) and particulate organic carbon ({POC}) concentrations were measured monthly at four stations of the {R}ed {R}iver system from {J}anuary 2008 to {D}ecember 2010. {T}he results reveal that {POC} changed synchronically with total suspended solids ({TSS}) concentration and with the river discharge, whereas no clear trend was observed for {DOC} concentration. {T}he mean value of total organic carbon ({TOC} = {DOC} + {POC}) flux in the delta of the {R}ed {R}iver was 31.5 x 10(13) +/- 4.0 x 10(13) {M}g{C}.yr (1) (range 27.9-35.8 x 10(13) {M}g{C}.yr (1) which leads to a specific {TOC} flux of 2012 +/- 255 kg{C}.km(-2).yr(-1) during this 2008-2010 period. {A}bout 80% of the {TOC} flux was transferred to the estuary during the rainy season as a consequence of the higher river water discharge. {T}he high mean value of the {POC}:{C}hl-a ratio (1585 +/- 870 mg{C}.mg{C}hl-a(-1)) and the moderate {C}:{N} ratio (7.3 +/- 0.1) in the water column system suggest that organic carbon in the {R}ed {R}iver system is mainly derived from erosion and soil leaching in the basin. {T}he effect of two new dam impoundments in the {R}ed {R}iver was also observable with lower {TOC} fluxes in 2010 compared with 2008.},
