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 the lack of a framework for estimating the inland water surface area and gas transfer velocity and by the absence of a global CO2 database. Here we report regional variations in global inland water surface area, dissolved CO2 and gas transfer velocity. We obtain global CO2 evasion rates of 1.8… 
Substantial decrease in CO2 emissions from Chinese inland waters due to global change
It is suggested that the CO2 emissions from Chinese inland waters have greatly offset the terrestrial carbon sink and are therefore a key component of China’s carbon budget.
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
Biogeochemistry: Conduits of the carbon cycle
The global emission rate from streams, rivers, lakes and reservoirs is estimated to be about two petagrams of carbon per year, which is higher than previous figures because of the contributions from streams and rivers.
Carbon dioxide emissions from the Three Gorges Reservoir, China
Carbon dioxide (CO2) emission from the river-type reservoir is an hotspot of carbon cycle within inland waters. However, related studies on the different types of reservoirs are still inadequate.
Methane and carbon dioxide emissions from inland waters in India – implications for large scale greenhouse gas balances
This study presents coordinated flux measurements of CH4 and CO2 in multiple lakes, ponds, rivers, open wells, reservoirs, springs, and canals in India and illustrates the importance of considering inland water GHG exchange in large scale assessments.
Large contribution to inland water CO2 and CH4 emissions from very small ponds
Very small ponds have been omitted from greenhouse gas budgets. Estimates of CO2 and CH4 emissions from 427 lakes and ponds show that very small ponds account for 15% of CO2 and 40% of diffusive CH4
Revision of methane and carbon dioxide emissions from inland waters in India
Substantial greenhouse gas (GHG) emissions including methane (CH4) and carbon dioxide (CO2) from inland waters have captured international concern (Barros et al., 2011; Bastviken et al., 2011;
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 from dry watercourses
Abstract Temporary watercourses that naturally cease to flow and run dry comprise a notable fraction of the world’s river networks, yet estimates of global carbon dioxide (CO2) emissions from


Carbon dioxide and methane emissions from the Yukon River system
Carbon dioxide (CO2) and methane (CH4) emissions are important, but poorly quantified, components of riverine carbon (C) budgets. This is largely because the data needed for gas flux calculations are
Amazon River carbon dioxide outgassing fuelled by wetlands
Wetland carbon export is potentially large enough to account for at least the 0.21 petagrams of carbon emitted per year as CO2 from the central Amazon River and its floodplains, suggesting a substantial fraction of CO2 evasion from inland waters.
Trends in the sources and sinks of carbon dioxide
Efforts to control climate change require the stabilization of atmospheric CO2 concentrations. This can only be achieved through a drastic reduction of global CO2 emissions. Yet fossil fuel emissions
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
CO2 emissions from saline lakes: A global estimate of a surprisingly large flux
[1] The role of saline lakes in CO2 exchange with the atmosphere was evaluated on the basis of calculated partial pressure (pCO2) and CO2 exchange rates with the atmosphere derived from a compilation
Plumbing the Global Carbon Cycle: Integrating Inland Waters into the Terrestrial Carbon Budget
A BSTRACTBecause freshwater covers such a small fraction of the Earth’s surface area, inland freshwater ecosystems (particularly lakes, rivers, and reservoirs) have rarely been considered as
Outgassing from Amazonian rivers and wetlands as a large tropical source of atmospheric CO2
It is suggested that the overall carbon budget of rainforests, summed across terrestrial and aquatic environments, appears closer to being in balance than would be inferred from studies of uplands alone.
Physical controls on carbon dioxide transfer velocity and flux in low‐gradient river systems and implications for regional carbon budgets
[1] Outgassing of carbon dioxide (CO2) from rivers and streams to the atmosphere is a major loss term in the coupled terrestrial-aquatic carbon cycle of major low-gradient river systems (the term
Carbon Dioxide Supersaturation in the Surface Waters of Lakes
Lakes are a small but potentially important conduit for carbon from terrestrial sources to the atmospheric sink, and the potential efflux of CO2 from lakes is about half as large as riverine transport of organic plus inorganic carbon to the ocean.
A catchment-scale carbon and greenhouse gas budget of a subarctic landscape
The overall catchment budget, given the size distribution of the individual ecosystem types and a first approximation of run-off as dissolved organic carbon, reveals a landscape currently with a significant sink capacity for atmospheric CO2, which is extremely sensitive to environmental changes, particularly those that affect the birch forest ecosystem.
