B42C:
Coastal Wetland Carbon: Recent Advances in Measurements, Modeling, and Syntheses II


Submit an Abstract to this Session


Session ID#: 59733

Session Description:
Coastal marshes, mangroves, and seagrass sequester significant amounts of “blue carbon” in soils, sediments, and biomass. Complex interactions of climate, land use, sea level, species composition, and human management regulate the strength of the carbon sinks and the greenhouse gas balance (including CO2, CH4, and N2O). Our ability to measure and model the vertical and lateral exchanges of coastal carbon at the land-ocean interface is limited. Their ecosystem services and the associated values of conservation and restoration in mitigating climate change have only recently been recognized. We aim to bring together biogeochemists, wetland ecologists, earth system modelers, ecological engineers, and social scientists to discuss coastal carbon pools and fluxes, and their roles in global carbon cycling and climate change mitigation. We also aim to report recent advances in measurement methods, including the eddy covariance and remote sensing techniques, modeling, and synthesis that support carbon accounting in coastal wetland ecosystems.
