Building a More Complete Representation of Methane Dynamics Across Earth's Ecosystems
Building a More Complete Representation of Methane Dynamics Across Earth's Ecosystems
Session ID#: 246841
Session Description:
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.
