  abstract = {{I}n {N}ovember 2011, the partial pressures of carbon dioxide (p{CO}(2)) in water and air in a floodplain lake of the {A}mazon {R}iver in {B}razil were 800 +/- 75 and 387 +/- 8 ppmv, respectively. {T}urbulent {CO}2 fluxes from the lake measured with eddy covariance ranged from 0.05 to 2.2 mmol m(-2) s(-1). {T}he corresponding gas transfer velocities k(600) ranged from 1.3 to 31.6 cm h(-1), averaging 12.2 +/- 6.7 cm h(-1). {A}t moderate to high wind speed, k(600) increased with wind speed, with values above parameterizations for other lake ecosystems. {D}uring the prevailing tropical low wind speed (below 2.7 m s(-1)) and high insolation conditions, unexpected high k(600) values (up to 20 cm h(-1)) were obtained and correlated with latent heat and sensible heat fluxes. {I}n {A}mazonian open lakes, owing to long quiescent periods of low wind speed but extremely high daytime insolation and heat fluxes, thermal enhancement makes time-integrated gas transfer velocities four to five times higher than those computed from classic wind parameterization.},
