Carbon Accumulation and Its Long-Term Stability in Blue Carbon Ecosystems II Posters

Session ID#: 84846

Session Description:
Blue carbon ecosystems (BCEs) are coastal ecosystems, such as salt marshes, mangroves, tidal freshwater wetlands, and seagrass meadows, with manageable and atmospherically significant carbon stocks and fluxes. Each of these systems stores organic carbon in its soils or sediments, which comprise its carbon sediment “sink”.  Such sequestration of carbon provides a valuable ecosystem service by mitigating carbon pollution.  Although carbon accumulation rates have been measured in all types of BCEs, less attention has been paid to the similarities and differences in carbon accumulation processes in different ecosystem types and the relative stability of carbon sediment sinks under sea-level rise and global climate change.  In this session, we invite those working in a variety of BCEs to present their work on carbon storage assessments, but with a particular focus on cross-BCE comparisons, process-level modeling, impacts from climate change/sea-level rise, carbon crediting, and restoration challenges.  We welcome papers from across the globe on empirical studies, modeling, and management concerns.  Our overall goal is to facilitate discussion on the science of carbon sequestration, challenges in implementation, and opportunities for partnering with land managers to increase long-term carbon storage in blue carbon sediment sinks.
