Dataset: Soil properties and accretion rates of C3 and C4 marshes at the Global Change Research Wetland, Edgewater, Maryland

This data release includes soil properties for marsh sediment cores taken in both a C3 (Schoenoplectus americanus) and C4 (Spartina patens) dominated marsh adjacent to the SMARTX warming plots at the Smithsonian Environmental Research Center. Large push cores were collected from each of the dominant vegetation types and analyzed for bulk density, % organic matter, and accretion rates using 210Pb analysis.
