Study Information

Abstract

This dataset includes salt marsh soil Pb-210, Cs-137, Bi-214, and Pb-214 radionuclide activities, bulk density, and loss on ignition measurements for soil cores collected at nine sites along the U.S. East Coast. Soil cores were collected in the following coastal salt marsh estuaries: Kennebec (ME), Plum Island (MA), Connecticut (CT), Delaware (NJ/DE), York (VA), James (VA), Cape Fear (NC), Edisto (SC), and Altamaha (GA). The data were used to determine rates of salt marsh vertical accretion and the change in accretion over time using the constant rate of supply model for Pb-210 activities.

Keywords: accretion, carbon sequestration, mineral, organic, sea level rise, salt marsh
