Lead 210 profiles in sediment cores in South Bay, Virginia

This dataset includes 210Pb (dpm g) and bulk carbon (mg/ml) data from four 20-cm sediment cores collected in South Bay, Virginia. Two of the cores were collected in 2011, one from within the restored Zostera marina (eelgrass) meadow and one from a nearby bare site. The other two cores were collected in 2014 from a different meadow site and a different bare site. Both meadow cores were collected within original restoration seed plots. The SB-5 bare core was collected north of the restored meadow. The 2-bare core was collected west of the meadow, near Man and Boy Channel. 210Pb and carbon profiles from the meadow sites were used to establish meadow carbon accumulation rates in 2011 and 2014, respectively. Bare areas in this system appear to be non-depositional. Excess 210Pb was not observed in the profiles from the two bare cores.
