Project: Delta Wetlands and Resilience: Blue Carbon and Marsh Accretion

Description: The funding for this project will be used to advance the science around and provide new quantification tools for carbon sequestration, greenhouse gas (GHG) emissions, elevation change, and marsh accretion and migration in tidal and managed wetlands in the Delta. This will include identifying critical knowledge gaps, thus setting the stage for more advanced modeling of these services. The outcomes of this study, will be delivered in journal publications, a dynamic scenario planning tool, and reports targeted for managers. As a result, this will lead to more informed decision-making, and development of more resilient and beneficial projects.

Reference Number: 3600BQ1996039

Implemented By: San Francisco Estuary Institute

Objective: Specific objectives of this Project are to: • Improve estimates of historic & current carbon sinks in the Delta • Produce a GIS tool, the Delta Landscape Scenario Planning Tool, to provide spatially explicit analysis of past, present and future carbon storage, GHG flux, elevation and subsidence in the Delta • Improve the organic matter accumulation functions in the Marsh Elevation Model (MEM) • Improve the sediment input functions in MEM to reflect changing sediment availability in the Delta • Identify necessary modifications to improve the MEM marsh accretion model for micro-tidal, tule-dominated freshwater marshes in the Delta • Estimate rates of carbon storage, subsidence, elevation change and GHG flux associated with current landscape position and for various restoration scenarios in the Delta • Assess the relative resiliency of Delta marshes to Sea Level Rise (SLR) • Model various wetland restoration scenarios to predict carbon sequestration and GHG benefits of different spatio-temporal restoration strategies • Provide organic and sediment accretion framework for a (future) spatially explicit model of marsh sustainability linking MEM with a hydrodynamic model for the CASCaDE II project • Estimate the historic, current, and future carbon storage in the Delta. • Synthesize and spatially display the best available science for variability in resilience of Delta tidal marshes to sea level rise • Disseminate results in operationalized formats to managers and scientists
