Short summary
Basin-wide comparisons of 3 major greenhouse gases (GHGs) were combined with measurements of C isotopes in DOC, CO2, and CH4 to explore how dams and urban wastewater modify the continuum of riverine GHG dynamics in a highly human-impacted river basin in Korea. Contrasting dam effects on 3 GHGs and pulsatile increases in GHGs downstream of urban tributaries delivering wastewater-derived GHGs and old DOC suggest anthropogenic discontinuities in riverine metabolic processes and GHG dynamics.
