Dissolved methane dynamics and isotopic source analysis in the Chongqing section of Yangtze River, Three Gorges Reservoir
Key Points
This research aims to analyze dissolved methane dynamics and sources in the Three Gorges Reservoir.
Isotopic analysis of methane sources and dynamics in the reservoir
Field sampling conducted in the Chongqing section
Assessment of methane emissions and carbon cycle interactions
Identified major sources of methane emissions in the reservoir, showing significant impacts on the local carbon cycle.
Found distinct isotopic signatures for methane sources within the Three Gorges environment.
Demonstrated variations in methane concentration correlating with seasonal changes.
Abstract
As the largest reservoir in China, the Three Gorges Reservoir is an important source of methane (CH4) emissions. In order to further understand the natural carbon cycle of CH4 in...
