Abstract:
Scientists from the U.S. Geological Survey (USGS), St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted a time-series collection of shallow sediment cores from the back-barrier environments along the Chandeleur Islands, Louisiana from March 2012 through July 2013. The sampling efforts were part of a larger USGS study to evaluate the effects on the geomorphology of the Chandeleur Islands following the construction of an artificial sand berm in response to the Deep Water Horizon oil spill. The objective of this study was to evaluate the response of the back-barrier tidal and wetland environments to the berm. This report serves as an archive for sedimentological, radiochemical, and microbiological data derived from the sediment cores. Data is available for a time-series of four sampling periods: March 2012; July 2013; September 2012; and July 2013. Data is available in downloadable spreadsheet, Joint Photographic Experts Group and Portable Document File formats. Additional files included: ArcGIS shape files of the study sites, detailed results of sediment grain size analyses, and formal Federal Geographic Data Committee (FDGC) metadata.
Purpose:
This zip archive, GIS_Core_Locations.zip, includes the sample locations in ESRI shapefile format for sediment samples collected from March 2012 to July 2013 from the Chandeleur Islands, Louisiana (U.S. Geological Survey Field Activity Numbers 12BIM01, 12BIM02, 12BIM05, and 13BIM06).

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The positional accuracy of the sample locations is determined by the accuracy of the raw position data recorded by the GPS antenna during data collection. Differential Geographic Positioning System (DGPS) coordinates were obtained using post-processing software packages (National Geodetic Survey's On-Line Positioning User Service (OPUS), version 2.2 and Waypoint Product Group's GrafNav and GrafNet, version 8.30).
Logical_Consistency_Report:
This dataset contains the post-processed DGPS coordinates for samples collected during four separate surveys in 2012 and 2013.
Completeness_Report:
This is a complete, processed physical parameters data file for the 12BIM01, 12BIM02, 12BIM05, and 13BIM06 core time series archive.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
All static base station sessions were processed through OPUS, and the results were entered into a spreadsheet to compute a final, time-weighted positional coordinate (latitude, longitude, and ellipsoid height). Base-station positional error for each GPS session was calculated as the absolute value of the final position minus the session position value. The maximum horizontal error of the base station coordinates used for post-processing the sample locations was 0.00018 seconds latitude and 0.00045 seconds longitude.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
All static base station sessions were processed through On-Line Positioning User Service (OPUS) maintained by the National Oceanic and Atmospheric Administration (NOAA) and the National Geodetic Survey (NGS). The base location results from OPUS were entered into a spreadsheet to compute a final, time-weighted positional coordinate (latitude, longitude, and ellipsoid height). Base-station positional error for each GPS session was calculated as the absolute value of the final position minus the session position value. For this survey, the standard deviation or the base station ellipsoid height was 0.006 m and the maximum vertical error for the base station was +/- 0.021 m. All sample locations were post-processed to the base station coordinates.
Lineage:
Process_Step:
Process_Description:
A GPS base station was erected at a temporarily installed USGS benchmark (TMRK) located on the sound side of the Chandeleur Islands within about 6 km of the furthest sample site. GPS receivers recorded the 12-channel full-carrier-phase positioning signals (L1/L2) from satellites via the Thales choke-ring antenna. This GPS instrument combination was duplicated on the rover GPS. The base receiver and the rover receiver record their positions concurrently at 1-second (s) recording intervals throughout the survey. Occupation times at the sample sites ranged from 5 to 30 minutes.

Process_Description:
The coordinate values of the GPS base station (TMRK) are the time-weighted average of values obtained from the National Geodetic Survey On-Line Positioning User Service (OPUS). The base station coordinates were imported into GrafNav and GrafNet, version 8.3 (Waypoint Product Group) and the GPS data from the rover were post-processed to the concurrent GPS session data at the base station. The GPS data were processed and exported in the World Geodetic System of 1984 (WGS84) (G1150) geodetic datum.
