U.S. Rivers and Streams Saturated With Carbon

Rivers and streams in the United States are releasing substantially more carbon dioxide into the atmosphere than previously thought, according to researchers publishing their results in the current issue of the journal Nature Geoscience.

Their findings could change the way scientists model the movement of carbon among land, water and the atmosphere.

"Direct measurements of carbon dioxide concentrations and fluxes in streams and rivers are still extremely rare," said Henry Gholz, program director in the National Science Foundation’s (NSF) Division of Environmental Biology, which funded the research.

"This study demonstrates that both are much higher than assumed. The research should enable more predictive and precise models of carbon cycling at regional to global scales."
