Atmospheric C (TAC) is continuously transported by rivers at the continents’ surface as soil dissolved and particulate organic C (DOC, POC) and dissolved inorganic C (DIC) used in rock weathering reactions. Global typology of the C export rates (g.m−2.yr−1) for 14 river classes from tundra rivers to monsoon rivers is used to calculate global TAC flux to oceans estimated to 542 Tg.yr−1, of which 37 % is as DOC, 18 % as soil POC and 45 % as DIC. TAC originates mostly from humid tropics (46 %) and… 

Fluvial organic carbon losses from a Bornean blackwater river

Concentrations of dissolved organic carbon (DOC) and particulate organic carbon (POC) were analysed from the source to the mouth of the River Sebangau in Cen- tral Kalimantan, Indonesia during the

Global-scale daily riverine DOC fluxes from lands to the oceans with a generic model

Predicting the oceanic input of organic carbon by continental erosion

For a large set of major world rivers we established the empirical relations existing between the observed organic carbon fluxes and the climatic, biologic, and geomorphologic patterns characterizing

Amounts, isotopic character, and ages of organic and inorganic carbon exported from rivers to ocean margins: 1. Estimates of terrestrial losses and inputs to the Middle Atlantic Bight

Rivers transport carbon (C) from terrestrial ecosystems to the coastal ocean, providing significant heterotrophic support within both rivers and receiving coastal waters. The amounts and ages of

Production, storage, and output of particulate organic carbon: Waipaoa River basin, New Zealand

We compute the particulate organic carbon (POC) yield of the Waipaoa River, New Zealand, using sediment rating curves in conjunction with measurements of the carbon content of the suspended sediment.

Storage of terrestrial carbon in boreal lake sediments and evasion to the atmosphere

Carbon mass balance studies of 20 small, forested catchments and seven lakes on the Precambrian Shield in central Ontario during a 12-year period have shown that most carbon in the study lakes is

Estimating the lateral transfer of organic carbon through the European river network using a land surface model

Abstract. Lateral carbon transport from soils to the ocean through rivers has been acknowledged as a key component of global carbon cycle, but is still neglected in most global land surface models



Sinks of the anthropogenically enhanced carbon cycle in surface fresh waters

The carbon chemistry of rivers and lakes has been severely affected by man's activities. This is evident from the data base of the SCOPE/UNEP project, Carbon Transport in Major World Rivers. Increase

Transport of organic carbon in the world’s rivers

Total transport of organic carbon to the world's oceans in dissolved and particulate form in rivers is estimated as 0.37 × 10 15 gC yr -1 by an inventory and extrapolation of data on loss of carbon

Transfer of particulate organic carbon and nitrogen from the Yangtze River to the ocean

The Yangtze River transports 12 million tons of particulate organic carbon (POC) to the oceans annually, with a computed yield of 6 t km/sup -2/ of drainage basin area. Concentrations of POC can

Geochemistry of the Amazon: 2. The influence of geology and weathering environment on the dissolved load

In the Amazon Basin, substrate lithology and erosional regime (seen in terms of transport-limited and weathering-limited denudation) exert the most fundamental control on the chemistry of surface

How to Establish and Use World Budgets of Riverine Materials

Average river water composition is often taken as a reference of surface water chemistry (Stumm and Morgan, 1981), and global river inputs have been used to set up the elemental mass balance of

Organic matter losses from four watersheds in the humid tropics1

Organic matter ( OM ) losses in runoff water were examined for four watersheds in Guatemala, ranging in size between 170 and 5,247 km2. Total organic matter (TOM) concentrations for the largest river

Global trends in the nature of organic matter in river suspensions

Riverine organic matter consists of a labile (metabolizable) and a residual (non-metabolizable) fraction1. The labile fraction can be oxidized or 'lost' within the rivers2, their estuaries3, and in
