TL;DR: In this article, the authors confirm the significance of greenhouse gas emissions from tropical reservoir but stress the importance of considering all the gas pathways upstream and downstream of the dams and taking into account the reservoir age when upscaling emissions rates at the global scale.

TL;DR: In this article, the authors measured simultaneously the methane (CH4) and carbon dioxide (CO2) surface concentrations and water-air fluxes by floating chambers (FC) in the Petit-Saut Reservoir (French Guiana) and its tidal river (Sinnamary River) downstream of the dam, during two field experiments in wet (May 2003) and dry season (December 2003).

TL;DR: In this paper, water-air fluxes were measured in three tropical reservoirs and their respective rivers downstream of the dams and the results showed that despite their relatively small surfaces, rivers downstream downstream of dams accounted for a significant fraction (9 − 33% for CH4 and 7 − 25% for CO2) of the emissions across the reservoir surfaces classically taken into account for reservoirs.

TL;DR: In this paper, the authors measured emissions of CH 4 and CO 2 from the hydroelectric dam of Petit Saut on the Sinnamary River in French Guyana over a 2 year period.

TL;DR: Galy-Lacaux et al. as mentioned in this paper presented emission fluxes and distributions of dissolved methane and carbon dioxide measured in the reservoir of Petit Saut over three and a half years, since the beginning of impounding (1994) and during operation (1995-1997).
