Dataset: Accretion rates and carbon sequestration in Oregon salt marshes
Blue Carbon is the carbon captured and stored in coastal ecosystems, such as seagrass meadows, and salt marsh habitat. As part of an EPA study focused on ecosystem services of tidal wetlands, we quantified the carbon sequestration and accretion rates in salt marsh habitat in eight Oregon estuaries (Alsea, Coos, Coquille, Nestucca, Netarts, Salmon, Tillamook, and Yaquina). Carbon sequestration rates were quantified using Cs-137 radioisotope, combined with bulk density and carbon content. This EPA dataset will be incorporated into products of the PNW Blue Carbon Working group, including the Pacific Northwest Blue Carbon Database and synthesis reports and manuscripts.
