Funding to collect and analyze these cores was provided by the U.S. Geological Survey Coastal and Marine Geology and Earth Surface Dynamics Programs. Assistance in the field was provided by Nick Ferina, Julie Bernier, and Jordan Sanford under the skilled leadership of captain David Bennett of the R/V Gilbert. Grain-size analyses were completed by Kate McMullen and Larry Poppe. Don Hickey assisted in the collection of samples for radiocarbon dating, and these samples were converted to graphite targets at the U.S. Geological Survey, Reston, VA, and analyzed at the Center for Accelerator Mass Spectrometry, Lawrence Livermore National Laboratory, Livermore, CA. Katie Merriweather and Ashley Daigle helped process microfossil samples at the USGS Foraminifieral Research Laboratory in St. Petersburg, FL. We benefited from valuable discussions with Lee Edmiston (Apalachicola Bay National Estuarine Research Reserve) on the natural history of oysters in the bay and Joe Donoghue (Florida State University) on the Quaternary evolution of the Apalachicola Bay region.  Reviews by Brian Buczkowski, Kate McMullen, and VeeAnn Cross helped the authors to substantially improve this report.
