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_Gamma_Spec_Data.zip file includes all gamma spectroscopy analysis results from Barnegat Bay, New Jersey collected in May 2014 (USGS FAN 2014-310-FA) by the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center.

Completeness_Report: This is a complete processed gamma spectroscopy data file for Barnegat Bay sediments collected during U.S. Geological Survey Field Activity 2014-310-FA. 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. Dried ground sediments (15 g) were sealed in airtight polypropylene containers. The sample weights and counting container geometries were matched to pre-made calibration standards. The sealed samples were allowed to sit for a minimum of 3 weeks to allow Ra-226 to come into secular equilibrium with its daughter isotopes Pb-214 and Bi-214. The sealed samples were then counted for 24 - 48 hours on a planar-style, low energy, high purity germanium, gamma-ray spectrometer. Sample count rates were corrected for detector efficiency (referenced to the IAEA RGU-1 standard), standard photopeak intensity, and self-absorption corrections using a U-238 sealed source. Activities are decay-corrected to the date of field collection.
