Although the brown pelican was delisted as an endangered species in 2009, nesting areas are threatened by continued land loss and are extremely vulnerable to storm impacts. The U.S. Fish and Wildlife Service proposed to restore Breton Island to pre-Hurricane Katrina conditions through rebuilding the shoreface, dune, and back-barrier marsh environments. Prior to restoration, scientists from the U.S. Geological Survey’s (USGS) St. Petersburg Coastal and Marine Science Center Geologic and Morphologic Evolution of Coastal Margins project collected high-resolution geophysical (topography, bathymetry, and sub-bottom profiles) and sedimentologic data from around Breton Island to characterize the geologic framework of the island platform, nearshore, and shelf environments. These data will be used to characterize the geologic framework around Breton Island, identify potential borrow areas for restoration efforts, quantify seafloor change, and provide information for sediment transport and morphologic change models to asses island response to restoration and natural processes. Data release doi:10.5066/F79C6VKF associated with this metadata record serves as an archive of sediment data from vibracores, push cores, and submerged grab samples collected from around Breton and Gosier Islands, Louisiana, during two surveys conducted in July 2014 and January 2015 (USGS Field Activity Numbers 2014–314–FA and 2014–336–FA, respectively). Sedimentologic and stratigraphic metrics (for example, sediment texture or unit thicknesses) derived from these data can be used to ground-truth the geophysical data and characterize potential sand resources or can be incorporated into sediment transport or morphologic change models. Data collection and processing methods are described in Data Series 1037 (https://doi.org/10.3133/ds1037). Data products, including sample location tables, descriptive core logs, core photographs and x-radiographs, results of sediment grain-size analyses, and geographic information system (GIS) data files with accompanying formal Federal Geographic Data Committee (FGDC) metadata can be downloaded from https://doi.org/10.5066/F79C6VKF. Purpose: Dissemination of processed sediment data from vibracores collected from around Breton Island, Louisiana, in January 2015 (USGS FAN 2014–336–FA). Supplemental_Information: From January 11-17, 2015, USGS scientists collected 56 vibracores were collected from back-barrier, nearshore, and offshore areas around Breton Island. Offshore vibracore locations were selected to ground-truth interpretations from previously collected seismic data (Forde and others, 2016).

The grain-size data presented in the summary statistics spreadsheets (https://coastal.er.usgs.gov/data-release/doi-F79C6VKF/data/2014-336-FA_GrainSize_SumStats.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 also reported, and the standard deviation of the averaged results are reported for most parameters. Sample depths were measured to the nearest half-centimeter using a metric tape measure. Logical_Consistency_Report: The geographic position and water depth of each core site was recorded at the time of collection with a Furuno depth sounder located amidship of the 110-foot M/V Thunderforce. The draft of the vessel was added to the reading to get the actual current water depth at the time of coring. The actual core site was offset from the back of the boat by up to 18 feet. Core elevations are the cell values extracted from a 100-meter cell size bathymetric grid derived from USGS bathymetric data (DeWitt and others, 2016). 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 (https://coastal.er.usgs.gov/data-release/doi-F79C6VKF/data/2014-336-FA_GrainSize_RunStats.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: Data release doi:10.5066/F79C6VKF associated with this metadata record includes the geographic locations, core descriptions, core photos, and grain-size data for 1,672 samples from 56 vibracores collected from around Breton Island, Louisiana, in January 2015 (USGS FAN 2014–336–FA).

Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The surface elevations of the vibracore sites are the cell values extracted from a 100-meter cell size bathymetric grid created from USGS bathymetric data (DeWitt and others, 2016). Lineage: Process_Step: Process_Description: USGS scientists collected 56 vibracores from around Breton Island in January 2015 (U.S. Geological Survey Field Activity Number 2014–336–FA). Cores were collected from the M/V Thunderforce, a 110-foot steel multiuse vessel operated by American Vibracore Services (AVS). This vessel uses an A-frame to lift the vibracore base onto the seafloor. An Alpine pneumatic vibracore head attached to a 5.08-cm (4-inch) diameter steel barrel with 9.21-cm (3.625-inch) diameter polycarbonate core liners was used to collect most of the samples. For the nine cores designated for optically stimulated luminescence (OSL) dating, a 7.62-cm (3-inch) diameter aluminum core barrel was used to shield the recovered sediments from light. A penetrometer with proprietary software developed by AVS was incorporated for real-time monitoring and recording of subsurface penetration. After extraction, each core was capped, sealed, and labeled with core number and orientation. The cores were transported to the USGS SPCMSC sediment lab for processing and analysis.

Grain-size samples consisted of 2-cm sections sampled at varying intervals down-core depending on the number and thickness of the observed sedimentologic units. Textural descriptions for the core logs are based on macroscopic observations; the quantitative grain-size data are represented by down-core plots on the core logs. Sediment color is based on the Munsell soil color system.

A total of 1,672 samples from 56 vibracores were analyzed. Core samples consisted of approximately 2-cm sections of the core. In order to prevent shell fragments from damaging the Coulter analyzers, particles greater than 1 mm in diameter were separated from all samples prior to analysis using a number 18 (1000 µm, 1 mm) U.S. standard sieve, which meets the American Society for Testing and Materials (ASTM) E11 standard specifications for determining particle size using woven-wire test sieves. Prior to sieving, samples were homogenized in the sample bag and wet-sieved to remove any large particles. Two subsamples from each sample were processed through the LS 200 or the LS 13 320 particle-size analyzers a minimum of three runs each. These instruments measure the particle-size distribution of each sample by passing sediment suspended in solution between two narrow panes of glass in front of a laser. Light is scattered by the particles into characteristic refraction patterns measured by an array of photodetectors as intensity per unit area and recorded as relative volume for 92 size-related channels (bins). The size-classification boundaries for each bin were specified on the basis of the ASTM E11 standard.

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 (1922) size scale. A macro developed by the USGS was applied to calculate the average and standard deviation of each sample (six runs per sample) and highlight runs that varied from the set average by more than plus or minus (±) 1.5 standard deviations. Excessive deviations from the mean are likely the result of equipment error or extraneous material in the sample and are not considered representative of the sample. Those runs were removed from the results and the sample average was recalculated using the remaining runs. The individual run statistics are available from https://coastal.er.usgs.gov/data-release/doi-F79C6VKF/data/2014-336-FA_GrainSize_RunStats.zip. The averaged results for all samples, including the number of runs used, the standard deviation of the averaged results, and class-size distributions, are summarized in a series of Excel workbooks with each core on its own tab and are available from https://coastal.er.usgs.gov/data-release/doi-F79C6VKF/data/2014-336-FA_GrainSize_SumStats.zip.

The Exif headers were initially populated by the camera’s imaging software but were subsequently updated by USGS staff to include core-related supplemental information. A Python version 2.7.3 script (UpdatePhotoEXIFv2.py) was run to incorporate location information and auxiliary details into the appropriate locations within the Exif header of each full-resolution JPEG image. The Python script used ExifTool version 10.25 to write the information to the image headers. The following tags were populated in the JPEG image headers. Information is duplicated in some tags.
