Contrasting methane emissions from upstream and downstream rivers and their associated subtropical reservoir in eastern China.

ABSTRACT: Subtropical reservoirs are an important source of atmospheric methane (CH₄). This study investigated the spatiotemporal variability of bubble and diffusive CH₄ emissions from a subtropical reservoir, including its upstream and downstream rivers, in eastern China. There was no obvious seasonal variation in CH₄ emissions from the main reservoir, which increased slightly from the first half year to the next half year. In the upstream river, CH₄ emissions were low from February to June and fluctuated widely from July to January due to bubble activity. In the downstream river, CH₄ emissions were lowest in February, which was possibly influenced by the low streamflow rate from the reservoir (275 m³ s^-1) and a short peri
