Our capacity to estimate regional and global budgets of greenhouse gases (GHG, including CO2, CH4 and N2O) from aquatic ecosystems has been significantly improved during the past decade, thanks to the substantial increase in field measurements. However, global estimates of these fluxes remain highly uncertain. Moreover, compared with terrestrial ecosystems, the field of aquatic GHG research is still young and the mechanisms behind the spatiotemporal patterns and variability of GHG concentrations and fluxes in aquatic ecosystems are not sufficiently understood, constraining model development. Therefore, to improve our estimations and understanding of regional and global GHG budgets from aquatic ecosystems, this session welcomes contributions on e.g.:
1) Field observations of GHG dynamics and fluxes in aquatic ecosystems, both freshwater and marine systems.
2) Experiments revealing physicochemical or biological processes or factors of relevance for GHG production, consumption, transport, emission, or uptake.
3) Model development or simulation efforts to estimate GHG dynamics and fluxes across different spatial and temporal scales along the aquatic continuum.
Contributions providing additional perspectives of relevance for aquatic GHG cycling and fluxes are also of interest.
