Soil Trace Gas Pulses: Measurements, Patterns, Mechanisms, and Impacts of Soil Responses to Drying and Re-wetting
Soil Trace Gas Pulses: Measurements, Patterns, Mechanisms, and Impacts of Soil Responses to Drying and Re-wetting
Session ID#: 156628
Session Description:
Re-wetting dry soils triggers pulses of biotic and abiotic metabolism that can dominate biogeochemical cycling in ecosystems that experience drought. These pulse events contribute to a significant fraction of total soil carbon, nitrogen, and VOC emissions from soils, and can play important roles in regional greenhouse gas and NOx budgets. Trace gas pulses are not well-parameterized in current biogeochemical models, in part due to the multiscale and dynamic nature of these events; however, technological and experimental advances are increasing the temporal and spatial resolution at which we can identify, characterize, and explain pulse responses to environmental drivers at multiple scales.
We welcome contributions that improve our abilities to measure trace gas pulses from soils and that quantify individual and interactive mechanisms that drive pulse dynamics. We also welcome submissions that address the inherent challenges of scaling re-wetting pulses to understand their contributions to regional and global biogeochemical budgets and that apply pulse paradigms toward sustainable soil management.
