Emissions of carbon dioxide from inland waters to the atmosphere are a crucial link in the global carbon cycle. A comprehensive analysis reveals that this connection is much stronger than was previously thought. See Article p.355 There has been a growing recognition in recent decades that inland waters release considerable amounts of CO2 into the atmosphere. Until now it has been difficult to obtain global estimates of how much carbon is transferred in this way. This study combines new data…

A review of CO2 and associated carbon dynamics in headwater streams: A global perspective
Terrestrial carbon export via inland aquatic systems is a key process in the global carbon cycle. It includes loss of carbon to the atmosphere via outgassing from rivers, lakes, or reservoirs and
Carbon Dioxide Emissions along the Lower Amazon River
A large fraction of the organic carbon derived from land that is transported through inland waters is decomposed along river systems and emitted to the atmosphere as carbon dioxide (CO2). The Amazon
Terrestrial carbon inputs to inland waters: A current synthesis of estimates and uncertainty
Globally, inland waters receive a significant but ill‐defined quantity of terrestrial carbon (C). When summed, the contemporary estimates for the three possible fates of C in inland waters (storage,
Where Carbon Goes When Water Flows: Carbon Cycling across the Aquatic Continuum
The purpose of this review is to highlight progress in unraveling carbon cycling dynamics across the continuum of landscapes, inland waters, coastal oceans, and the atmosphere. Earth systems are
Low contribution of internal metabolism to carbon dioxide emissions along lotic and lentic environments of a Mediterranean fluvial network
Inland waters are significant sources of carbon dioxide (CO2) to the atmosphere. CO2 supersaturation and subsequent CO2 emissions from inland waters can be driven by internal metabolism, external
Emissions from dry inland waters are a blind spot in the global carbon cycle
Groundwater data improve modelling of headwater stream CO 2 outgassing with a stable DIC isotope approach
Abstract. A large portion of terrestrially derived carbon outgasses as carbon dioxide (CO 2) from streams and rivers to the atmosphere. Particularly, the amount of CO 2 outgassing from small
Organic carbon transport in the Songhua River, NE China: Influence of land use
Carbon transported by rivers is an important component of the global carbon cycle. Here, we report on organic carbon transport along the third largest river in China, the Songhua River, and its major
Fluvial carbon export and CO2 efflux in representative nested headwater catchments of the eastern La Plata River Basin
This study involved a baseline evaluation of fluvial carbon export and degas rates in three nested rural catchments (1 to 80 km2) in Taboão, a representative experimental catchment of the Upper

Global carbon dioxide emissions from inland waters
Carbon dioxide (CO2) transfer from inland waters to the atmosphere, known as CO2 evasion, is a component of the global carbon cycle. Global estimates of CO2 evasion have been hampered, however, by
Riverine coupling of biogeochemical cycles between land, oceans, and atmosphere
Streams, rivers, lakes, and other inland waters are important agents in the coupling of biogeochemical cycles between continents, atmosphere, and oceans. The depiction of these roles in global-scale
Carbon dioxide and methane emissions and the carbon budget of a 10-year old tropical reservoir (Petit Saut, French Guiana)
The emissions of carbon dioxide (CO2) and methane (CH4) from the Petit Saut hydroelectric reservoir (Sinnamary River, French Guiana) to the atmosphere were quantified for 10 years since impounding in
Organic carbon and nitrogen export from a tropical dam-impacted floodplain system
Tropical floodplains play an important role in organic matter transport, storage, and transformation between headwaters and oceans. However, the fluxes and quality of organic carbon (OC) and organic
Differential mobilization of terrestrial carbon pools in Eurasian Arctic river basins
TLDR
By radiocarbon dating various terrestrial OC components in fluvially and coastally integrated estuarine sediments, a unique framework is presented for deconvoluting the contrasting mobilization mechanisms of surface vs. deep (permafrost) carbon pools across the climosequence of the Eurasian Arctic.
The global abundance and size distribution of lakes, ponds, and impoundments
One of the major impediments to the integration of lentic ecosystems into global environmental analyses has been fragmentary data on the extent and size distribution of lakes, ponds, and

The terrestrial biosphere is assumed to take up most of the carbon on land. However, it is becoming clear that inland waters process large amounts of organic carbon and must be considered in
