Title:
Sediment Sample Locations Collected in May 2014 from Barnegat Bay, New Jersey (U.S. Geological Survey Field Activity Number 2014-310-FA)
Abstract:
Barnegat Bay, located along the eastern shore of New Jersey, was significantly impacted by Hurricane Sandy in October 2012. 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.

Why was the data set created?

The 14BRN_Site_Information.zip file includes core location information and water quality parameters for sampling sites occupied in Barnegat Bay, New Jersey from May 12-14, 2014 by the U.S. Geological Survey (USGS), St. Petersburg Coastal and Marine Science Center.

How was the data set created?

  2. How were the data generated, processed, and modified?
    Date: 2014 (process 1 of 2)
    Water quality parameters including salinity, pH, temperature, dissolved oxygen (DO), specific conductance, and oxidation-reduction potential (ORP), were collected at each site using a YSI Professional Plus multiparameter meter at a depth of 1 m below the water surface. Water depth was also recorded at all sample locations at the time of collection by direct measurement. Site coordinates were recorded on a Garmin GSPmap 62Stc handheld Global Positioning System (GPS) receiver. Person who carried out this activity:
