Carbon sequestration rates in managed and tidal freshwater marshes in the Waccamaw National Wildlife Refuge, South Carolina This SSP project resulted in one publication. Carbon storage was compared between impounded and naturally tidal freshwater marshes along the Lower Waccamaw River in South Carolina, USA. Soil cores were collected in (1) naturally tidal, (2) moist soil (impounded, seasonally drained since ~1970), and (3) deeply flooded "treatments" (impounded, flooded to ~90 cm since ~2002). Cores were analyzed for % organic carbon, % total carbon, bulk density, and 210Pb and 137Cs for dating purposes. Carbon sequestration rates ranged from 25 to 200 g C m-2 yr-1 (moist soil), 80-435 g C m-2 yr-1 (naturally tidal), and 100-250 g C m-2 yr-1 (deeply flooded). The moist soil and naturally tidal treatments were compared over a period...
