Spatial variability of CO2 and CH4 concentrations from Petit-Saut reservoir (French Guiana)

Variability in greenhouse gas emissions from reservoirs creates uncertainty in global estimates of C emissions from reservoirs. We measured CO2 and CH4 surface water concentrations at 44 sites in the reservoir (including sites in open, littoral and transitional areas) during the dry season in 2018. We linked gas concentrations with environmental parameters.

水库温室气体排放的变异性导致了全球对水库碳排放估计的不确定性。我们在2018年干旱季节对水库内44个地点（包括开阔、沿岸和过渡区域）的CO2和CH4地表水浓度进行了测量。我们将气体浓度与环境参数进行了关联。
