Accurately measuring and predicting methane (CH₄) fluxes is crucial for enhancing modeling capabilities to respond effectively to climate and land-use change. However, our incomplete understanding of CH₄ dynamicsbetween the biosphere, pedosphere, and atmosphere in terrestrial and aquatic ecosystems has led to large uncertainties. This session aims to bridge connections and evaluate differences in CH₄ dynamics through the soil-plant continuum and Earth’s Critical Zone across a variety of climates and ecosystems. We encourage submissions that (1) explore CH₄ production and oxidation pathways, including CH₄ soil uptake, via biogeochemical or microbiome analyses, (2) identify soil-vegetation interactions through the rhizosphere using biogeochemical and physiological studies across a range of landscape positions and hydrologic conditions, (3) develop methods for scaling plot-level observations in CH₄ dynamics to the ecosystem or landscape levels, and (4) examine the impact of observational errors and model uncertainties on CH₄ fluxes.
