Session ID#: 15416

Session Description:
Coastal marshes, mangroves, and seagrass meadows sequester significant amounts of “blue carbon.” The complex interactions of climate, land-use, sea level, species composition, and human management regulate the strength of these carbon sinks. Compared with terrestrial ecosystems, our ability to measure and model the vertical (CO2 and CH4) and lateral (DOC and DIC) exchanges of carbon in coastal wetlands in the interface of the land, atmosphere, and ocean is limited. Their ecosystem services and the associated values of conservation and restoration in mitigating climate change have only recently been recognized by policymakers, coastal managers, and the society at large. We aim to bring together biogeochemists, wetland ecologists, earth system modelers, and social scientists to discuss the quantity of coastal blue carbon and its role in global carbon cycling and climate change mitigation; and to report recent advances in measurement methods and modeling ability to predict and evaluate the blue carbon credit.
