Linking Terrestrial Carbon Cycle Timescales and Processes
Linking Terrestrial Carbon Cycle Timescales and Processes
Session ID#: 250629
Session Description:
Understanding impacts of global climate, land use, and biodiversity changes on terrestrial carbon pools and fluxes requires accurate quantification of rates of carbon cycling. Quantifying these changes requires detecting signals in heterogeneous systems, identifying functional carbon pools, and determining controls on fluxes into, out of, and between these pools.Isotopic methods are uniquely suited for tracking timescales of carbon cycling, particularly radiocarbon, δ13C (e.g., C3/C4 transitions), and other radionuclides. Measurements of carbon cycling rates made with any of these methods can serve as powerful constraints for models, although each method has limitations and biases. We invite contributions from empirical studies (field & laboratory) across scales that use radiocarbon or other isotopic tracers to quantify timescales of terrestrial carbon cycling, quantify method biases, or identify functional carbon pools in soils (including microbes) and vegetation, as well as model-based approaches using observations of these tracers to constrain carbon stocks or fluxes.
