TL;DR: In this paper, the role of inland water ecosystems in the global carbon cycle has been investigated and it is shown that roughly twice as much C enters inland aquatic systems from land as is exported from land to the sea, roughly equally as inorganic and organic carbon.
Journal ArticleDOI
Outgassing from Amazonian rivers and wetlands as a large tropical source of atmospheric CO2.
TL;DR: 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.
Journal ArticleDOI
The global control of silicate weathering rates and the coupling with physical erosion: new insights from rivers of the Canadian Shield
TL;DR: The chemical evolution of the surface of the Earth is controlled by the interaction of rainwaters, the atmosphere and the continental crust as discussed by the authors, which is the main reason why the knowledge of the parameters that control chemical denudation on Earth is of crucial importance.

Carbon isotope fractionation of dissolved inorganic carbon (DIC) due to outgassing of carbon dioxide from a headwater stream
Daniel H. Doctor,Carol Kendall,Stephen D. Sebestyen,James B. Shanley,Nobuhito Ohte,Elizabeth W. Boyer +5 more
TL;DR: The stable isotopic composition of dissolved inorganic carbon (DIC) was investigated as a potential tracer of streamflow generation processes at the Sleepers River Research Watershed, Vermont, USA as discussed by the authors.

Spatial patterns in CO2 evasion from the global river network
Ronny Lauerwald,Ronny Lauerwald,Goulven Gildas Laruelle,Goulven Gildas Laruelle,Jens Hartmann,Philippe Ciais,Pierre Regnier +6 more
TL;DR: In this article, the authors presented the first global maps of CO2 partial pressures (pCO2) in rivers of stream orders 3 and higher and the resulting FCO2 at 0.5° resolution constructed with a statistical model.

Study and Interpretation of the Chemical Characteristics of Natural Water
TL;DR: The chemical composition of natural water is derived from many different sources of solutes, including gases and aerosols from the atmosphere, weathering and erosion of rocks and soil, solution or precipitation reactions occurring below the land surface, and cultural effects resulting from human activities.
