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.
