Small artificial waterbodies are widespread and persistent emitters of methane and carbon dioxide
Abstract Inland waters play an active role in the global carbon cycle and emit large volumes of the greenhouse gases (GHGs) methane (CH4) and carbon dioxide (CO2). A considerable body of research has improved emissions estimates from lakes, reservoirs, and rivers but recent attention has been drawn...

Abstract Inland waters play an active role in the global carbon cycle and emit large volumes of the greenhouse gases (GHGs) methane (CH4) and carbon dioxide (CO2).
