Project: Restoring Living Shorelines: Opportunities to Combine Shore Protection with Amelioration of Ocean Acidification

Description: The grantee will implement eelgrass restoration as a part of living shoreline projects to combine opportunities for shore protection with carbon storage (in living biomass) and sequestration (buried), and amelioration of ocean acidification (pH increased during periods of active photosynthesis).

Reference Number: 0540P01209

Implemented By: San Francisco State University, Estuary and Ocean Science Center

Objective: 1) Restore eelgrass at two living shorelines sites (San Rafael and Giant Marsh, near Richmond) in San Francisco Bay. 2) Gather some of the first measurements of eelgrass “blue carbon” in restoration projects in the state or elsewhere, and determine if initial planting density benefits establishment and, in turn, carbon storage and sequestration. 3) Use co-location of eelgrass with native oysters at living shorelines projects to evaluate oyster reef protection of eelgrass from wave disturbance and feedbacks to ecosystem functions and services, including capacity to buffer pH and sequester carbon. 4) Assess effects of eelgrass on pH and carbonate chemistry that may benefit shell formation in native oysters and other species as ocean acidification intensifies.
