Open AccessIntegrating terrestrial and aquatic ecosystems to constrain estimates of land-atmosphere carbon exchange
In this Perspective, we put forward an integrative framework to improve estimates of land-atmosphere carbon exchange based on the accumulation of carbon in the landscape as constrained by its lateral export th...

Open AccessHow humans alter dissolved organic matter composition in freshwater: relevance for the Earth’s biogeochemistry
Dissolved organic matter (DOM) is recognized for its importance in freshwater ecosystems, but historical reliance on DOM quantity rather than indicators of DOM composition has led to an incomplete understandin...

Open AccessRepresenting the function and sensitivity of coastal interfaces in Earth system models
Between the land and ocean, diverse coastal ecosystems transform, store, and transport material. Across these interfaces, the dynamic exchange of energy and matter is driven by hydrological and hydrodynamic pr...

Constraining dissolved organic matter sources and temporal variability in a model sub-Arctic lake
Circumpolar lakes comprise ~ 1.4 million km2 of arctic and subarctic landscapes and are vulnerable to change in vegetation, permafrost distribution, and hydrological conditions in response to climate warming. How...

Open AccessSimilarity of stream width distributions across headwater systems
The morphology and abundance of streams control the rates of hydraulic and biogeochemical exchange between streams, groundwater, and the atmosphere. In large river systems, the relationship between river width...

Erratum: Global carbon dioxide emissions from inland waters
Nature 503, 355–359 (2013); doi:10.1038/nature12760 In Fig. 1a of this Article, the highest value on the colour scale should be 11,772 instead of 1,772. This has been corrected in the HTML and PDF versions of ...

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 the lack of a f...

Anthropogenic aerosols as a source of ancient dissolved organic matter in glaciers
Glacier-derived dissolved organic matter represents a quantitatively significant source of ancient, but bioavailable, carbon to downstream ecosystems. Anthropogenic aerosols supply glaciers with aged organic m...

Significant efflux of carbon dioxide from streams and rivers in the United States
Current estimates of carbon dioxide evasion from inland waters are based on incomplete spatial coverage. Streams and rivers in the United States release 97 Tg of carbon to the atmosphere each year, according t...
