Description:

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.

Purpose:

14BRN_Grain-Size_Data.zip file includes Excel spreadsheets summarizing particle size 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.

Supplemental_Information:

The reported data are the calculated averages of multiple instrument analyses. The results of individual sample runs, and standard deviations for all sample averages are included in the unedited output files (http://pubs.usgs.gov/10.3133/ds993/downloads/14BRN_Grain-Size_Run_Statistics.zip). Sample runs in the output files for which the mean Folk and Ward grain size varied from the set average by more than 1.5 standard deviations are highlighted in yellow and were not included in final averaged results.

Attribute_Accuracy:

Attribute_Accuracy_Report:

The grain size data presented in the run statistics spreadsheets (http://pubs.usgs.gov/10.3133/ds993/downloads/14BRN_Grain-Size_Data.zip) represent the sample averages for a subset of the statistical parameters calculated by GRADISTAT. The number of runs included in the averaged results are reported, and the standard deviation of the averaged results are reported for most parameters.

Logical_Consistency_Report:

The complete grain size dataset including all GRADISTAT parameters, results of individual sample runs, and standard deviations for all sample averages are included in the unedited output files (http://pubs.usgs.gov/10.3133/ds993/downloads/14BRN_Grain-Size_Run_Statistics.zip). Sample runs in the output files for which the mean Folk and Ward grain size varied from the set average by more than 1.5 standard deviations are highlighted in yellow and were not included in final averaged results.

Completeness_Report:

This is a complete grain size dataset that includes results for 30 surface sediment and 191 subsurface sediment samples sectioned from sediment cores collected in Barnegat Bay and Little Egg Harbor, New Jersey in May 2014 (U.S. Geological Survey Field Activity Numbers 2014-310-FA).

Process_Step:

Process_Description:

Eight box cores and 22 ponar grab samples, subsectioned into 221 surface and subsurface sediment samples, were collected from Barnegat Bay and Little Egg Harbor, New Jersey in May 2014 (USGS Field Activity Numbers 2014-301-FA, and 2014-322-FA). Samples were transported to the USGS St. Petersburg, FL Coastal and Marine Science Center (SPCMSC) for analysis.

Process_Step:

Process_Description:

Prior to particle size analysis, all samples had organic material chemically removed using approximately 8 mL of 30% hydrogen peroxide (H2O2) overnight. The H2O2 was then evaporated and the sediment was washed and centrifuged twice with deionized water.

Process_Step:

Process_Description:

Grain-size analyses were performed using a Coulter LS200 (https://www.beckmancoulter.com/) particle-size analyzer, which uses laser diffraction to measure the size distribution of sediments ranging in size from 0.4 μm to 2 mm (clay to very coarse-grained sand). In order to prevent shell fragments from damaging the LS200, particles greater than 1 mm in diameter were separated from all sediments prior to analysis using a number 18 U.S. standard sieve. If there was sediment > 1 mm, the material was dried and the dry weight was recorded. After the samples were washed through the sieve with filtered municipal water, a few milliliters of sodium hexametaphosphate solution was added to act as a deflocculant. The sediment slurry was sonicated with a wand sonicator for 30 – 60 seconds before being introduced into the Coulter LS200 to breakdown aggregated particles. The pre-sieved <1 mm dried fraction was introduced directly into the Coulter LS200. Two subsamples from each sample were processed through the Coulter LS200 a minimum of three runs each.

Process_Step:

Process_Description:

The raw grain-size data were processed with the free software program GRADISTAT (Blott and Pye, 2001; http://www.kpal.co.uk/gradistat), which calculates the mean, sorting, skewness, and kurtosis of each sample geometrically in metric units and logarithmically in phi units (Φ) (Krumbein, 1934) using the Folk and Ward (Folk, 1957) method. GRADISTAT also calculates the fraction of sediment from each sample by size category (for example, clay, coarse silt, fine sand) based on a modified Wentworth (Wentworth, 1922) size scale. A macro function in Microsoft Excel, developed by the USGS SPCMSC, was applied to the data to calculate average and standard deviation for each sample set (six runs per sample), and highlight runs that varied from the set average by more than ± 1.5 standard deviations. Excessive deviations from the mean are likely the result of equipment error or extraneous organic material in the sample and are not considered representative of the sample. The highlighted runs were removed from the results and the sample average was recalculated using the remaining runs.
