Scientists from the U.S. Geological Survey (USGS) developed a multidisciplinary study of sediment transport and hydrodynamics to understand the mechanisms that govern estuarine and wetland responses to storm forcing. This report details the physical and chemical characteristics of surficial and downcore sediments from two areas within the bay. Eleven sites were sampled in both the central portion of the bay near Barnegat Inlet and in the southern portion of the bay in Little Egg Harbor. Laboratory analyses include Be-7, Pb-210, bulk density, porosity, x-radiographs, and grain-size distribution. These data will serve as a critical baseline dataset for understanding the current sedimentological regime and can be applied to future storms for understanding estuarine and wetland evolution. This report serves as an archive for sedimentological and radiochemical data derived from the surface sediments and box cores. Downloadable data are available as Excel spreadsheets, PDF files, and JPEG files, and includes sediment core data plots and x-radiographs, as well as, physical-properties, grain-size, alpha-spectoscopy, and gamma-spectroscopy data. Federal Geographic Data Committee metadata are available for analytical datasets in the data downloads page of this report. Purpose: The 14BRN_Alpha_Spec_Data.zip file includes all alpha spectroscopy radiochemistry analysis results from the eight box cores collected from Barnegat Bay, New Jersey in May 2014 (USGS FAN 2014-310-FA) by the U.S. Geological Survey (USGS), St. Petersburg Coastal and Marine Science Center.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The radioisotopic activities reported in the Microsoft Excel spreadsheets include the counting error for all samples. Logical_Consistency_Report: The data include core ID, sample depth interval in core (cm), total Pb-210 activity, and total Pb-210 counting error. Completeness_Report: This is a complete processed alpha spectroscopy radiochemistry data file for USGS FAN 2014-310-FA (14BRN). Lineage: Process_Step: Process_Description: In the field, the cores were sectioned at 1-cm intervals for the length of the core, placed in individual storage bags, and stored on ice. The section core samples were transported to the USGS SPCMSC.

The dried sediment was homogenized to a fine powder using a porcelain mortar and pestle. Total Pb-210 (via granddaughter polonium-210; [Po-210]) was determined by alpha spectroscopy following the procedure of Marot and Smith (2012). Briefly, approximately 5 g of sediment was spiked with 0.5 mL of Po-209 of known activity (12 decays per minute per milliliter [dpm mL-1]). Sediments were leached with a combination of concentrated nitric and hydrochloric acid with the addition of 30 % hydrogen peroxide (H2O2) to remove organics. Sediments were taken to near dryness and re-saturated three times with hydrochloric acid until all nitric acid was removed. Po-209 and Po-210 were electroplated onto silver planchets and counted on an alpha spectrometer. Count rate efficiencies for Po-209 were determined and applied to Po-210 counts. Total Pb-210 is then assumed to be in secular equilibrium with Po-210 in the down-core sediment.
