Cores were typically on the order of tens of centimeters to one meter long. Cores were subsampled in the field in 1-cm increments and returned to the lab for grain-size, loss-on-ignition (organic content), and/or Pb-210 isotope analyses on selected intervals. Not every interval of each core was analyzed for every parameter. Sandier cores were not analyzed for Pb-210. For muddy cores, organic contents and grain-size distributions were analyzed in greater abundance than Pb-210. The files provided include one netcdf file for each of the twelve cores. Each file contains grain-size distribution data for each interval in the core that was analyzed. The files for Brown’s Cove (BC), Bull Island (BI), Charleston (CH), Crown Point (CP), East Flats 2 (EF2), Isthmus Slough (IS), Kentuck Flats (KF), and Kunz Marsh (KM) all include down-core lead-210 (Pb-210) isotope activity data. These are total activities (i.e., they have not been corrected for in situ or supported lead production; see Souza, 2022 for discussion). All files except the files for Crown Point, East Flats, Kentuck Flats, and North Point include down-core organic content data. This dataset is available to the public for a wide variety of uses including scientific research and analysis.
