abstract = "We used a three-dimensional model to assess the dynamics of
diffusive carbon dioxide flux (FCO2) from a hydroelectric
reservoir located at Amazon rainforest. Our results showed that
for the studied periods (2013 summer/wet and winter/dry seasons)
the surface averaged FCO2 presented similar behaviors, with
regular emissions peaks. The mean daily surface averaged FCO2
showed no significant difference between the seasons (p > 0.01),
with values around -1338 mg C m - 2 day - 1 (summer/wet) and -1395
mg C m - 2 day - 1 (winter/dry). At diel scale, the FCO2 was large
during the night and morning and low during the afternoon in both
seasons. Regarding its spatial distribution, the FCO2 showed to be
more heterogeneous during the summer/wet than during the
winter/dry season. The highest FCO2 were observed at transition
zone (-300 mg C m - 2 h - 1) during summer and at littoral zone
(-55 mg C m - 2 h - 1) during the winter. The total CO2 emitted by
the reservoir along 2013 year was estimated to be 1.1 Tg C year -
1. By extrapolating our results we found that the total carbon
emitted by all Amazonian reservoirs can be around 7 Tg C year - 1,
which is 22% lower than the previous published estimate. This
significant difference should not be neglected in the carbon
inventories since the carbon emission is a key factor when
comparing the environmental impacts of different sources of
electricity generation and can influences decision makers in the
selection of the more appropriate source of electricity and, in
case of hydroelectricity, the geographical position of the
reservoirs.",
