This session will focus on the investigation of the three major greenhouse gas fluxes (CO2, CH4 and N2O) from terrestrial and aquatic ecosystems with a strong focus on methane (CH4) and/or nitrous oxide (N2O) fluxes. Given the fact that both CH4 and N2O emissions from land or water bodies (lakes, reservoirs and streams) can easily offset known carbon sinks (when converted to CO2-eq.), and that knowledge on the drivers of CH4/N2O as well as their temporal and spatial variability is still limited, we encourage measuring, monitoring and modeling studies of both greenhouse gases.
Studies that focus on testing hypotheses, isolating mechanisms, specific processes, upscaling, technological advancement and identifying knowledge gaps are of particular interest. With this session we aim to integrate both the aquatic and terrestrial communities that study GHG budget. Therefore studies that already link terrestrial and aquatic GHG budgets would be most suitable for this session, however studies that present only one or the other are still encouraged stimulating discussion regarding the lack of interaction between the two sides. We specifically look for contributions from emerging new research infrastructures that focus on the biogeochemical cycles such as ICOS (Integrated Carbon Observation System), National Ecological Observation Network (NEON), Terrestrial Ecological Research Network (TERN), and others.
