Anthropogenic effects on greenhouse gas (CH4 and N2O) emissions in the Guadalete River Estuary (SW Spain)

by Rebecca Herrera

Burgos et al. (2014) discuss seasonal variations of the greenhouse gases methane (CH4) and nitrous oxide (N2O) in the Guadalete River Estuary ending in the Cadiz Bay of southwestern Spain. They found that greenhouse gas concentrations were higher in the more inland parts of the estuary compared to the mouth of the river. Concentrations of methane and nitrous oxide varied depending largely upon the seasonal precipitation regime. It was also observed that the Guadalete Estuary acted as a source, rather than a sink, of greenhouse gases throughout the entire year, as observed by measuring the fluxes of CH4 and N2O from the Estuary.
