Aquatic habitats in the lowland Amazon emit large quantities of carbon dioxide (CO2). However, information on CO2 fluxes from seasonally flooded forests that constitute 80% of the surface area of aquatic environments in the lowland Amazon basin is sparse. We provide the first multi-year measurements of CO2 exchanges within flooded forests of the central Amazon basin. Our approach combines measurement of dissolved CO2 concentrations and fluxes between the water and atmosphere and ecological data. Although the rates of CO2 emission by flooded forests are lower than other aquatic habitats, such as open waters in rivers and lakes, the combination of high CO2 concentrations and a large area results in an appreciable regional out gassing of carbon dioxide from flooded forests. These fluxes can represent about half of the net primary production of flooded forests in the central Amazon basin.
