Abstract:

In response to the 2010 Governor’s Action Plan to clean up the Barnegat Bay–Little Egg Harbor (BBLEH) estuary in New Jersey, the U.S. Geological Survey (USGS) partnered with the New Jersey Department of Environmental Protection in 2011 to begin a multidisciplinary research project to understand the physical controls on water quality in the bay. Between 2011 and 2013, USGS scientists mapped the geological and morphological characteristics of the seafloor of the BBLEH estuary using a suite of geophysical tools. However, this mapping effort included only surficial characterization of bay sediments; to verify the sub-surface geophysical data, sediment cores were required. Data Series 985 associated with this metadata record serves as an archive of sedimentologic data from 18 vibracores collected from Barnegat Bay between May and August of 2014 by the U.S. Department of Agriculture Natural Resources Conservation Service (NRCS) on behalf of the USGS. The vibracores were collected in conjunction with an ongoing NRCS subaqueous soil survey for the BBLEH estuary. The data presented in this report, including descriptive core logs, core photographs, processed grain-size data, and Geographic Information System (GIS) data files with accompanying formal Federal Geographic Data Committee metadata, can be viewed or downloaded from https://pubs.usgs.gov/ds/985/ds985_data/.

Purpose:

This zip archive includes the grain-size data in Microsoft Excel format and associated metadata for sediment samples from vibracores collected in 2014 from Barnegat Bay, New Jersey.

Supplemental_Information:

The locations of vibracore sites were chosen based on analysis of high-resolution seismic reflection profiles collected by the USGS throughout the bay (Andrews and others, 2015). A total of 18 marine vibracores were collected from Barnegat Bay in water depths greater than 1.5 meters (m) between May and August of 2014 from the NRCS Research Vessel (R/V) Doerner. A vessel-mounted tripod system was used to position, deploy, and recover the vibracores. At two additional target sites, coring efforts failed to recover sediment. A 5 1/2-horsepower Briggs and Stratton motor attached to a concrete vibrator head with a 3-m shaft was used to vibrate 7.62-centimeter (cm) diameter aluminum core barrels into the estuarine seafloor to refusal. After recovery, cores were capped, sealed, and labeled. Measurements of compaction were recorded for each core based on a comparison of the external riser height and the depth of the sediment-water interface inside the barrel. Date, time, site location (latitude and longitude), water depth, tidal period, total extracted core length, and estimated compaction were recorded for each core. All vibracores were stored in a refrigerator at the NRCS Plant Materials Center (PMC) in Cape May, N.J., until they were transported from the NRCS PMC to the USGS St. Petersburg Coastal and Marine Science Center (SPCMSC) in early September for description and textural analysis. Surficial sediments previously collected from Barnegat Bay were analyzed in the sediment laboratory at the Woods Hole Coastal and Marine Science Center (WHCMSC); therefore, the inorganic sample fractions were returned to that laboratory for textural analysis to facilitate comparisons. Coarse fractions (sand and gravel) were oven-dried, weighed and dry-sieved. Fine fractions (silt and clay) were analyzed using a Multisizer 3 Coulter Counter, which uses electrical impedance to measure the size distribution of sediments ranging in size from 0.4 to 1,200 microns (micrometers, μm). The combination of both techniques allows for the weight percentages of grain sizes from -5 to 11 phi to be determined. The sediment classification and frequency percentages were calculated using GSSTAT software (Poppe and others, 2004). The grain-size data can be viewed or downloaded from https://pubs.usgs.gov/ds/985/ds985_data/.

Attribute_Accuracy_Report:

The positional accuracy of the core locations is determined by the accuracy of the Hemisphere Crescent XF100 Series Global Positioning System (GPS) receiver used to locate the samples at the time of collection. Sample depths were measured to the nearest centimeter using a metric tape measure. The sediment textural data was analyzed using standard procedures at the Woods Hole Coastal and Marine Science Center (WHCMSC). Coarse fractions (sand and gravel) were dry-sieved, and fine fractions (silt and clay) were analyzed using a Multisizer 3 Coulter Counter. The sediment classification and frequency percentages were calculated using GSSTAT software (Poppe and others, 2004).

At the SPCMSC core-analysis laboratory, each vibracore was cut into 1-m sections and split in half lengthwise. One-half of each core was described using standard sediment-logging methods then photographed, sealed, and archived at the SPCMSC core repository. The other half was sub-sampled for grain-size analysis based on physical description.

Process_Step:

Process_Description:

The percent total organic matter (TOM) for 38 samples from 10 cores was determined using a mass loss technique known as loss-on-ignition (LOI). Samples were selected when visual characteristics indicated high organic matter content. During LOI processing, samples were combusted at high temperatures, oxidizing all organic carbon and allowing determination of mass loss by weight. Bulk wet samples were split, homogenized, placed on pre-weighed aluminum trays, and weighed. All weights were recorded with a precision of 0.01 grams (g) using an analytical balance. The wet sediment and tray were placed inside a drying oven pre-heated to 60 degrees Celsius (°C) for 48 hours. Water content was determined as the mass of water (lost when dried) relative to the initial wet sediment mass. The dried samples were homogenized using a porcelain mortar and pestle. Approximately 5 g of the ground sediment was placed in a pre-weighed porcelain crucible, weighed, and then placed inside a laboratory muffle furnace equipped with stabilizing temperature controls. The furnace was heated to 110 °C for a minimum of 6 hours to remove hygroscopic water absorbed onto the sediment particles. The furnace temperature was then lowered to 60 °C and the sediment was reweighed. The dried sediment was returned to the furnace and heated to 550 °C for 6 hours. The furnace temperature was cooled and held at 110 °C overnight, and then cooled to 60 °C before weighing. The mass lost during the 6-hour baking period, relative to the 110 °C dry mass, was used as a metric of organic matter content. The LOI organic content of the 38 organic-rich samples ranged from 0.91 to 77.55 percent. Prior to grain-size analysis, these samples were chemically leeched of all organic matter to prevent organics from being counted as part of the sample and biasing the grain-size distribution. Organic matter was removed from the samples using approximately 8 milliliters (mL) of 30 percent hydrogen peroxide (H2O2) overnight. The H2O2 was then evaporated through slow heating on a hot plate, and the sediment was washed and centrifuged twice with deionized water. Due to the high organic content of some samples, excess amounts of H2O2 were added to induce reactions and ensure full digestion.

Process_Description:

Surficial sediments previously collected from Barnegat Bay were analyzed in the sediment laboratory at the Woods Hole Coastal and Marine Science Center (WHCMSC); therefore, the inorganic sample fractions were returned to that laboratory for textural analysis to facilitate comparisons. For the analysis of the inorganic sediment fraction, approximately 50 grams (g) of wet sample were wet-sieved through a 0.062 millimeter (mm) sieve to separate the coarse and fine fractions. For several of the organic-rich samples, less than 50 g of wet sediment remained after the organic matter was removed. In two cases, the organic content was high enough that an insufficient amount of inorganic sediment remained for textural analysis. Coarse fractions (sand and gravel) were oven-dried, weighed and dry-sieved. Fine fractions (silt and clay) were analyzed using a Multisizer 3 Coulter Counter, which uses electrical impedance to measure the size distribution of sediments ranging in size from 0.4 to 1,200 microns (micrometers, μm). The combination of both techniques allows for weight percentages of grain sizes from -5 to 11 phi (ϕ) to be determined. The sediment classification and frequency percentages were calculated using GSSTAT software (Poppe and others, 2004).
