Title:
Vibracore locations collected in 2014 from Barnegat Bay, New Jersey
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/0985/ds985_data/.
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 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 2 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-meter 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.
